    Practices of SeeingVisual Analysis : An Ethnomethodological Approach

    Charles Goodw in

    A p rimord ial site for the an alysis of hum an langu age, cognition an d action

    consists of a situation in which mu ltiple participan ts are attempting to carry out

    courses of action together while attending to each other, the larger activities that

    their cur rent actions are embedded within, and relevant phenomena in their

    surrou nd . Vision can be central to this p rocess.1. The visible bodies of

    participan ts provide systematic, changing d isplays about relevant action an d

    orientation. Seeable structure in the environment can not only constitute a locus

    for shared visual attention, but can also contribute crucial semiotic resources for

    the organization of current action (consider for example the u se of graphs an d

    charts in a scientific d iscussion). For the past thirty years both Conversation

    Analysis and Ethnom ethodology have p rovided extensive analysis of how

    hu man vision is socially organized . Both fields investigate the p ractices that

    participan ts use to build and shape in concert with each other the stru ctured

    events that constitute the lifeworld of a comm un ity of actors. Phenomena

    investigated in which vision plays a central role range from sequ ences of talk, to

    medical and legal encounters, to scientific knowledge.

    The approach taken by both ethnomethodology and conversation analysis to

    the study of visual p henom ena is qu ite distinctive. At least since Saussure

    proposed studying langue as an an alytically distinct subfield of a more

    encompassing science of signs, different kinds of semiotic phenomena (language,

    visual signs, etc.) have typ ically been analyzed in isolation from each other.

    How ever in the work to be d escribed here neither vision, nor the images or other

    phenomena that participan ts look at, are treated as coherent, self-contained

    1 Vision is not, however, essential as both the comp etence of the blind and

    teleph one conversations d emonstrate. Below it will be argued that situated

    action is accomplished through the juxtaposition of multiple semiotic fields,

    only some of wh ich m ake vision relevant.

    dom ains that can be su bjected to analysis in th eir own terms. Instead it quickly

    becomes app arent that visual ph enomena can only be investigated by taking into

    account a diverse set of semiotic resources and meaning-making practices that

    participan ts dep loy to build th e social worlds that they inhabit and constitute

    through on going processes of action. Many of these, such as stru cture provided

    by current talk, are not in any sense visual, but the visible phenomena that the

    participan ts are attend ing to cannot be prop erly analyzed w ithout them. The

    focus of analysis is not thu s not rep resentations or v ision p er se, but instead the

    part p layed by visual phenomena in the prod uction of meaningful action.

    Both the m ethodology and the forms of analysis used in this app roach can

    best be demonstrated throu gh sp ecific examples.

    Gaze between Speakers and HearersIn formu lating the d istinction between comp etence and performance Chomsky

    (1965: 3-4) argu ed that actual speech is so full of perform ance errors, such as

    sentence fragments, restarts and pau ses, that both lingu ists and p arties faced

    with the task of acquiring a langu age should ignore it. Investigating a corpus of

    conversation recorded on video Goodwin (1980a, 1981, Chapter 2) indeed found

    precisely the false starts and changes of plan in m id-course that Chomsky

    describes. In the following instead of prod ucing an u nbroken gramm atical

    sentence the speaker says:2

    2 Talk is transcribed using the system d eveloped by Gail Jefferson (see Sacks,

    Schegloff and Jefferson Sacks, et al. 19 74: 731-733). Talk receiving som e formof emphasis is marked with und erlining or bold italics. Punctuation is used to

    transcribe intonation: A period indicates falling pitch, a question mark rising

    pitch, and a comm a a falling contour, as wou ld be found for examp le after a

    non-terminal item in a list. A colon indicates lengthening of the current sound .

    A d ash marks the sud den cut-off of the current sound (in English it is

    frequen tly realized as glottal stop). Comm ents (e.g., descriptions of relevant

    nonvocal behavior) are pr inted in italics within dou ble parentheses. Num bers

    within single parentheses mark silences in second s and tenths of a second . A

    degree sign () ind icates that th e talk that follows is being spoken with low

    How ever, when the video is examined it is foun d th at the restart occurs at a

    specific place: precisely at the point w here the speaker br ings her gaze to her

    add ressee, and finds that her add ressee is looking elsewhere:

    Gaze Arrives

    Moreover, the restart acts as a request for the Hearers gaze. Thu s immed iately

    after the restart the h earer starts to move her gaze to the speaker.

    Paradoxically, if the speaker had not p rodu ced a restart at this point she

    could h ave said something that w ould ap pear to be an unbroken gramm atical

    unit if one examined only the stream of speech (e.g., En a coup le of girls from

    there ), but which would in fact be interactively a sentence fragment since her

    add ressee attended to only part of it.

    The identities of speaker an d hearer are th e most generic participan t

    categories relevant to th e produ ction of a strip of talk. The p henomena examined

    here (which occur pervasively in conversation) provide evidence that the w ork of

    volume. Left brackets connecting talk by d ifferent sp eakers mark the p oint

    where overlap begins.

    being a hearer in face-to-face interaction requires situated use of the body, and

    gaze in particular, as a w ay of visibly displaying to others th e focus of ones

    orientation. Moreover speakers not on ly use their own gaze to see relevant action

    in the bod y of a silent hearer, bu t actively change the structure of their emerging

    talk in term s of what th ey see.

    What relevance do p rocesses such as th ese have to the oth er issue raised by

    Chom sky (1965 :3), that of d etermining from the data of performance the

    underlying system of rules mastered by the speaker-hearer? Many repairs

    involve the rep etition, with some significant change, of something said elsewh ere

    in the u tterance:

    We wen t- I went to

    If he could- If you could

    Such rep etition has the effect of delineating th e boun dar ies and stru cture of

    many d ifferent units in the stream of speech. Thu s, by analyzing w hat is the

    same an d wh at is d ifferent in these examples one is able to d iscover: First, where

    the stream of speech can be d ivided into significant subu nits; second , that

    alternatives are p ossible in a p articular slot; third, wh at some of these

    alternatives are (here d ifferent p ronouns); and fourth, that these alternatives

    contrast w ith each other in some significant fashion, or else the rep air wou ld not

    be war ranted . Repairs in other examples not only d elineate basic un its in the

    stream of speech (noun p hrases for examp le), but also demonstrate the different

    forms su ch units can take, and th e types of operations that can be performed

    up on th em (see Goodwin 1981 :170-173). Repairs further requ ire that a listener

    learn to recognize that not all of the sequences within the stream of speech are

    possible sequences within the language, e.g., that I does not follow to in We

    went t- I went to . In ord er to deal with such a repair a hearer is thus required

    to make one of the most basic distinctions posed for anyone attemp ting to

    decipher the stru cture of a langu age: to differentiate what are and are not

    possible sequences in th e language, that is between gram matical and

    un gramm atical structures. The fact that this task is posed m ay be crucial to any

    learning process. If the party attemp ting to learn the language d id not have to

    deal w ith ungram matical possibilities, if for example she was exposed to only

    well-formed sentences, she might not have the data necessary to d etermine the

    boundar ies, or even the structure of the system. Chomskys argument that the

    repairs found in natu ral speech so flaw it that a child is faced with data of very

    degenerate qu ality does not app ear warranted. Rather it might be argued that

    if a child g rew u p in an ideal world w here she heard only well-formed sentences

    she would not learn to p rodu ce sentences herself because she w ould lack the

    analysis of their structure p rovided by events such as repair. Crucial to this

    process is the way in wh ich visual phenomena , such as dispreferred gaze states

    can both lead to repair, and d emonstrate that the participan ts are in fact

    attending in fine detail to wh at might ap pear to be quite ephem eral structure in

    the stream of speech.

    What h as just been d escribed p rovides one example of the method ologies and

    forms of analysis used to investigate visual ph enomena within Conversation

    Analysis. Several observa tions can be m ade. First, the focus of analysis is not

    visual events in isolation, but instead the systematic practices used by

    participants in interaction to achieve courses of collaborative action with each

    other in the p resent case the interactive construction of turns at talk, and the

    utterances that emerge w ith those turn s. Visual events, such as gaze, play a

    central role in th is process but their sense and relevance is established th rough

    their embedd edness in other mean ing making tasks and practices, such as the

    prod uction of a strip of talk that is in fact heard and attended to by its add ressee.

    This links vision to a h ost of other phenom ena includ ing language an d the visible

    body as an unfolding locus for the display of meaning and action. Second , what

    the analyst seeks to do is not to provide his or her ow n gloss on how v isual

    phenomena m ight be m eaningful, but instead to demonstrate how the

    participan ts themselves not on ly actively orient to par ticular kinds of visual

    events (such as states of gaze), bu t use them as a constitu tive featu re of the

    activities they are engaged in (for example by modifying th eir talk in terms of

    wh at they demonstrably see). Third, in addition to the spatial dimension that is

    natu rally associated w ith vision, these p rocesses also have an intrinsic temporal

    dimension as changes in visual events are marked by, and lead to, ongoing

    changes in the organ ization of emerging action. If one had only a static snap shot,

    or measured only a single structural possibility, such as mutu al gaze instead of

    looking a t the temp orally u nfolding interplay of different combinations of

    participan t gaze, the type of analysis being pursued here would be impossible.

    Fourth, such analysis requires data of a particular type, specifically a record that

    maintains as much information as possible about the setting, embod ied displays

    and spatial organization of all relevant participan ts, their talk, and h ow events

    change throu gh time. In p ractice no record is comp letely adequ ate. Every camera

    position exclud es other views of what is hap pening. The choice of where to p lace

    the camera is but the first in a long series of crucial analytical decisions. Despite

    these limitations a video or film record d oes constitute a relevant d ata source,

    something that can be worked w ith in an imperfect world .

    Fifth, crucial problems oftranscription are posed. The task of translating the

    situated, embod ied p ractices used by p articipants in interaction to organize

    phenomena relevant to vision p oses enorm ous theoretical and m ethodological

    problems. Our ability to transcribe talk is built up on a process of analyzing

    relevant stru cture in the stream of speech, and marking those distinctions with

    wr itten symbols, that extends back thousand s of years, and is still being mod ified

    today (for examp le the system developed by Gail Jefferson (Sacks, Schegloff and

    Jefferson 1974: 731-733) for transcribing the texture of talk-in-interaction,

    includ ing phenom ena, such as momentary restarts and sou nd stretches, that are

    crucial for the analysis being reported here). When it comes to the transcription

    of visual ph enomena we are at the very beginning of such a p rocess. The arrows

    and other symbols Ive used to mark gaze on a transcript (see Goodw in 1981)

    capture on ly a small part of a larger comp lex constituted by bod ies interacting

    together in a relevant setting. The decision to describe gaze in terms of the

    speaker-hearer framework is itself a major analytic one, and by no means simp le,

    neutral description. Moreover a gazing head is embed ded within a larger

    postu ral configuration, and indeed different par ts of the body can

    simultaneously d isplay orientation to different p articipants or regions (see

    Kend on 1990b, Schegloff 1998), creat ing participation frameworks of

    considerable complexity. Thus on occasion a transcriber w ants some way of

    indicating on the p rinted page posture and alignment. In ad dition, not only the

    bodies of the participants, but also phenomena in their surrou nd , can be crucial

    to the organization of their action. To try to m ake the ph enomena Im analyzing

    independently accessible to the reader so that she or he can evaluate m y analysis,

    Ive experimented w ith using tran scription symbols, frame grabs, diagrams, and

    movies embedded in electronic versions of papers. Multiple issues are involved

    and no method is entirely successful. On the one han d th e analyst needs

    materials that maintain as mu ch of the original structure of the events being

    analyzed as p ossible, and wh ich can be easily and repetitively replayed. On the

    other hand, just as a raw tape recording d oes not display the analysis of

    segmental structure in the stream of speech p rovided by transcription with a

    phonetic or alph abetic writing system, in itself a video, even one that can be

    embedd ed w ithin a paper, does not provide an analysis of how visible events are

    being parsed by p articipants. The comp lexity of the phenom ena involved

    requires multiple methods for rendering relevant d istinctions (e.g., accurate

    transcription of speech, gaze notation, fram e grabs, diagrams, etc., see also Ochs

    1979). Moreover , like the two-faced Roman god Janus, any tran scription system

    mu st attend simultaneously to two separate fields, looking in one direction at

    how to accurately recover throu gh a systematic notation the end ogenous

    structure of the events being investigated, while simultaneously keeping an other

    eye on the add ressee/ reader of the analysis by attemp ting to present relevant

    descript ions as clearly and vividly as possible. In man y cases d ifferent stages of

    analysis and presentation w ill require m ultiple transcriptions. There is a

    recursive interplay between analysis and method s of description.

    Work in Conversation Analysis has provid ed extensive stud y of how the gaze

    of participants tow ard each oth er is consequen tial for the organization of action

    within talk-in-interaction. Phenomena investigated include th e way in w hich

    speakers change the structure of an emerging utterance, and the sentence being

    constructed within it, as gaze is moved from one typ e of recipient to another, so

    that the u tterance maintains its app ropriateness for its addressee of the mom ent

    (Goodw in 1979, 1981); how speakers modify d escript ions in term s of their

    hearers visible assessment of wh at is being said (M.H. Goodwin 1980b); how

    genres such as stories are constructed not by a speaker alone, but instead

    through the d ifferentiated visible d isplays of a range of structurally d ifferent

    kind s of recipients (speaker, pr imary addressee, pr incipal character, etc. See

    Goodwin 1984); the organization of gaze and co-participation in medical

    encoun ters (Heath 1986, Robinson 1998); the interactive organization of

    assessments (Goodw in and Goodw in 1987), gesture (Goodw in in press, Streeck

    1993, 1994), the u se of gaze in activities such as w ord searches (M.H. Good win

    and C. Goodw in 1986), etc. Though not strictly lodged within Conversation

    Analysis the w ork of Kendon (1990a. 1994, 1997) on both the interactive

    organ ization of bodies as they frame states of talk, and on gesture, is central to

    the stu dy of visible behavior in interaction. Haviland (1993) provides imp ortant

    analysis of the interactive organization of gesture within narration (for extensive

    analysis of gesture from a p sychological perspective see McNeill 1992).

    Scientific Images

    The visible, gazing bod y, and the orientation of participants tow ard eachother as they co-prod uce states of talk is central to the w ork in

    ConversationalAnalysis just examined . By w ay of contrast mu ch work w ithin

    Ethnomethod ology has focused not on th e bodies of actors, but instead on the

    images, diagrams, graph s and other visual p ractices used by scientists to

    construct the crucial visual working environm ents of their d isciplines. As noted

    by Lynch and Woolgar (1990:5):

    Manifestly, what scientists laboriously piece together, pick up in

    their hand s, measure, show to one another, argue about, and

    circulate to others in th eir comm un ities are not natural objects

    indep enden t of cultural processes and literary forms. They are

    extracts, tissue cultures, and residu es imp ressed w ithin grap hic

    matrices; ordered, shaped, and filtered samples; carefully aligned

    ph otograph ic traces and chart record ings; and verbal accoun ts.

    These are the p roximal things" taken into th e laboratory and

    circulated in p rint and they are a rich repository ofsocial

    actions.

    Despite importan t d ifferences in su bject matter and method ology both fields

    emphasize the importan ce of focusing not on representations or other v isual

    phenomena as self-contained en tities in their own right, but instead on how they

    are constructed, attend ed to, and used by par ticipants as componen ts of the

    p. 162

    10/40

    endogenous activities that make u p the lifeworld of a setting. Thus, in

    introdu cing their imp ortant volume onRepresentation in Scientific Practice Lynch

    and Woolgar (1990: 11) define their inqu iry as follows:

    Instead of asking what d o we m ean, in various contexts, by

    representation? the stud ies begin by asking, What do the participants,

    in this case, treat as representation?

    Note that what m ust be investigated is specified both in term s of the orientation

    of the pa rticipants, and with respect to the features of the relevant local setting

    (e.g., in this case). This leads to a distinctive ethn omethod ological persp ective

    on reflexivity :

    Reflexivity in th is usage m eans, not self-referential nor reflective

    awareness of representational practice, but the inseparability of a theory

    of representation from the h eterogeneous social contexts in wh ich

    representations are composed and used (Lynch and Woolgar 1990 12).

    In a classic article Lynch (1990 :153-154) formulates the task of analyzing

    scientific representa tions as that of describing the publicly visible externatized

    retina that is the site for the p ractices implicated in the social constitution of the

    objects that are th e focus of scientific work:

    This study is based on the prem ise that visual displays are more

    than a simple matter of supplying p ictorial illustrations for

    scientific texts. They are essential to how scientific objects and

    orderly relationships are revealed an d mad e analyzable. To

    app reciate this, we first need to wrest the idea ofrepresentation from

    an ind ividu alistic cognitive foundation, and to replace a

    preoccup ation with images on th e retina (or alternatively mental

    images or pictorial ideas) with a focus on the externalized retina

    of the graphic and instrum ental fields u pon which the scientific

    image is imp ressed and circulated.

    Using as d ata images from scientific journal art icles and books Lynch describes

    two families of practices used to constitu te the visible scientific object: selection

    and mathematization. Selection, illustrated through dou ble images in wh ich a

    photograph and a diagram of entities visible in the ph otograph are presented

    side by side, is described as a host of practices that iteratively transform one

    p. 163

    11/40

    10

    image of an entity into another (e.g. the photograp h to the diagram) while

    simultaneously structuring and shap ing what it is that is being represented.

    Crucial to this process is that fact that d ifferent selective/ shaping practices,

    including Filtering, Uniforming, Upgrading and Defining can be repetitively

    app lied creating not just a single image, but a linked, d irectional chain of

    representations Indeed mu ch of the w ork of actually d oing science consists in

    building and shap ing what Latour (1986) (see also Latou r and Woolgar 1979)

    have called inscriptions in this fashion. Mathematization refers not simp ly to

    the use of nu mbers, but instead to the host of practices used to tr ansform

    recalcitrant events into mathematically tractable visual and graphic displays e.g.,

    graph s, charts and d iagrams. Thus an image showing a map of lizard territories

    is assembled throu gh, among oth er operations, driving stakes into the lizard s

    environment to create a grid for measurement (and thus injecting a scientifically

    relevant Cartesian sp ace into the very h abitat being stud ied), repetitively

    capturing lizards, distingu ishing th em from each other by cutting off a different

    pattern of toes on each lizard, recording each capture on a pap er map of the

    staked ou t territory, and finally draw ing lines around collections of points to

    create the m ap . As noted by Lynch (1990: 171) the p rod uct of these p ractices, e.g.,

    the published map , is a hybrid object that is demon strably mathem atical,

    natural and literary. Note how in all of these cases the focus of analysis is on the

    contextually based practices of the participan ts who are assembling an d using

    these images to accomp lish the w ork that defines their p rofession.

    Though em erging from psychological anthropology, rather than

    ethnomethdology, Hutchins (1995) grou nd breaking stud y of the cognitive

    practices required to nav igate a ship outlines a major p erspective for the an alysis

    of both images and seeing as forms of work-relevant p ractice. Hu tchins

    dem onstrates how the practices required to navigate a ship are not situated

    within the mental life of a single individu al, but are instead em bedd ed w ithin a

    distributed system that encomp asses visual tools such as maps and instruments

    for juxtaposing a land mark and compass bearing within the same visual field,

    and actors in stru cturally d ifferent p ositions wh o use alternative tools and, in

    part because of this, perform d ifferent kind s of cognitive operations, many of

    wh ich h ave a strong visual comp onent (e.g., locating land marks, p lotting

    positions on a map, etc.).

    Images in Interaction

    All of the work discussed so far takes as its point of departure for theinvestigation of visual ph enomena the task of describing an d analyzing the

    practices used by participan ts to construct the actions and events that m ake up

    their lifeworld. Rather than stand ing alone as a self-contained analytic dom ain,

    visual ph enomena are constituted and mad e meaningful through the way in

    wh ich they are embedd ed w ithin this larger set of practices. However, within

    this common focus, two quite d ifferent ord ers of visual p ractice have been

    examined. Research in science studies has investigated the images prod uced by

    scientists, and the way in w hich they visually and math ematically structure thewor ld that is the focus on their inquiry, without h owever looking in much detail

    at how scientists attend to each other as living, meaningful bodies, or structure

    wh at they are seeing through the organ ization of talk-in-interaction. By w ay of

    contrast studies of the interactive organ ization of vision in conversation looked

    in considerable detail at how participan ts treat the visual displays of each

    others bodies as consequential, and how this is relevant to the moment-by-

    moment production of talk, but d id not focus m uch analysis on images in the

    environment. Clearly all of the phenomena noted the visible body,

    participation, gesture, the d etails of talk and language u se, visual structure in the

    surrou nd , images, maps and other representational practices, the pu blic

    organ ization of visual practice within the worklife of a profession, etc. are

    relevant. The question arises as to wh ether it is possible to analyze such d isparate

    phenomena w ithin a coherent analytic framework.

    Before turn ing to stud ies that have probed such questions several issues must

    be noted . First, it is clearly not the case that the on ly acceptable analysis is one

    that includes th is full range of all possible visual p henom ena. Both p articipants

    and the structures that p rovide organization for action and events use visible

    phenomena selectively. Parties speaking over the telephone can see neither either

    others bodies nor events in a common surrou nd . A scientific journ al can be read

    in the absence of the parties who constructed its text and d iagrams. More

    interestingly within face-to-face interaction participants can continuously shift

    between actions that invoke, and p erhaps require, gaze toward specific events in

    the surround , and those make relevant gaze toward no more than each others

    bodies, and even in th is more limited case there may be a real issue as to whether

    it is relevant to attend to everything that a body does, e.g., some gestures mad e

    by a speaker may not requ ire gaze toward them from an ad dressee. There is thu s

    an essential contingency, not only for the analyst bu t more crucially for the

    participants themselves, as to what su bset of possible visual events are in fact

    relevant to the organ ization of the actions of the mom ent. Moreover, this means

    that in ad dition to investigating how different kinds of visible phenom ena are

    organized, the analyst mu st also take into account how participan ts show each

    other what kind s of events they are expected to take into account at a p articular

    mom ent, for example to indicate that a participan t, gesture, or entity in th e

    surrou nd should be gazed at. There is thus not only comm un ication through

    vision, bu t also ongoing comm un ication abou t relevant vision (Goodw in 1981,

    1986; in p rep aration, Streeck 1988).

    Second visual events are quite heterogeneous, not only in wh at they m ake

    visible, but more crucially in their structure. Consider for example the issue of

    temporality. Both gestures and the d isplays of postu ral orientation used to bu ild

    participation framew orks are performed by th e body w ithin interaction.

    However, while gestures, like the bits of talk they accompany, are typically brief

    (e.g. they frequently fall within the scope of a single utterance) and display

    semantic content relevant to th e topic of the m oment, participation d isplays

    frame extended strips of talk and typically provide information abou t the

    participants orientation rather th an the specifics of wh at is being d iscussed.

    Bodily displays with one kind of temp oral du ration (and information content)

    are thus embed ded within another class of visual displays being mad e by the

    body w hich have a quite different structure.

    Third , the structure of visual signs, including their possibilities for

    prop agation through space and time, can be intimately tied to the medium used

    to construct them. A major theme of Shakespeares sonnets focuses on the

    contrast between the temporally constrained hu man bod y, cond emned to

    inevitable decay, and the (limited) possibilities for transcending such corruption

    provid ed by language inscribed on the p rinted page which can remain fresh and

    alive long after its author an d subject have passed into du st. This contrast

    between th e temp oral possibilities provided by alternative media (e.g., the bod y

    and docum ents) constitutes an ongoing resource for pa rticipants in vernacular

    settings as they bu ild, throu gh interaction w ith each other, the events that make

    up their lifewor ld. In ad dition to the d isplays made by a fleeting gesture or local

    participation framework, participants also have access to images and docum ents

    wh ich can encompass m ultiple interactions and quite d iverse settings. This arises

    in par t from the specific media u sed to constitute the signs they contain. Rather

    than being lodged within an ever changing hu man body, such d ocum ents

    constitute w hat Latou r (1987: 223) has called imm utable mobiles, portable

    material objects that can carry stable inscriptions of various types from place to

    place and through time.

    However, despite the way in w hich crucial aspects of the structure of images

    and docum ents remain constant in d ifferent environm ents, they are not self-

    contained visual artifacts that can be analyzed in isolation from the processes of

    interaction and w ork practices through w hich they are mad e relevant and

    meaningful. The same image or docum ent can be construed in quite different

    ways in alternat ive settings. For example, a schedule listing all arriving and

    dep arting flights was a m ajor tool for almost all workgroups at th e airport

    stud ied by the Xerox PARC workplace project (Brun-Cottan et al. 1991, Goodwin

    and Goodw in 1996, Suchman 1992), and indeed it linked diverse w orkers

    throughou t North America into a common w eb of activity. However w hile

    baggage loaders carefully structured their work to anticipate arriving flights, so

    that p lanes could be speedily unloaded , these same arrival times were almost

    ignored by gate agents looking at the same schedule, but concerned w ith the

    dep arture of passengers. Each work group h ighlighted the comm on docum ent in

    ways relevant to the specific work tasks it faced. Similarly, on the oceanographic

    ship reported in Goodwin (1995) a map showing where samples would be taken

    in the Atlantic at the mou th of the Amazon, was a major docum ent at all stages

    of the research project. Before the ship sailed th e places where samples could be

    taken w as the focus of intense political debate betw een d ifferent grou ps of

    scientists and the Brazilian and American governm ents; after the project was

    15/40

    14

    comp leted the map p rovided an infrastructure for graph ic displays that could be

    used in pu blished journal articles to show wh at the scientists had found about

    how the w aters of the Am azon and the Atlantic interacted w ith each other, i.e., a

    way of making visible relevant scientific phenomena; during the voyage itself the

    map not only provided a comm on framework for the quite different work of

    various teams of scientists and the crew nav igating the sh ip, but could also be

    looked at by lab technicians not able to go to bed for days at a time because of the

    map s incessant samp ling d emand s, to locate places wh ere stations w ere far

    apart and rest was p ossible. In brief, though the material form of images and

    docum ents gives them an extended temporal scope, and the ability to travel from

    setting to setting, they cann ot be analyzed as self-conta ined fields of visually

    organized m eaning, but instead stand in a reflexive relationship to th e settings

    and p rocesses of embodied hum an interaction through w hich they are

    constituted as m eaningful entities. To explicate such events ana lysis must deal

    simultaneously with th e quite different structure and temporal organization of

    both local embodied p ractice and endu ring graph ic displays.

    Finally, the visual (and other p roperties) of settings stru cture environments

    that sh ape, on an historical time scale, the activities systematically performed

    within th ose settings. A very simp le examp le is provided by the bridge of the

    oceanographic ship which not only had a wind ow facing forward so the

    helmsman could steer the ship and watch for trouble, but also a window facing

    backward s. This was u sed by a w inch operator who had the task of lifting heavy

    instrument packages in and out of the sea. Though being u sed here to d o science,

    this arrangem ent is in fact a systematic solution to a repetitive problem faced by

    sailors, such as fishermen using n ets, who have to m aneuver heavy objects while

    a sea. Solutions found to these tasks, such as the rear facing w indow with the

    visual access it provides (as well as the forward window facilitating n avigation),

    are built into the tools that constitute the work environments u sed by subsequent

    actors faced w ith similar tasks. See Hutchins (1995) for illum inating analysis of

    this process, includ ing tools that visually structure complex mathematical

    calculations, as well as map s. Both w ork environm ents and many of the tools

    used within them (comp uter d isplays, etc.) structure in quite specific ways the

    embodied visual p ractices of those who inhabit such settings.

    15

    In an attemp t to come to terms w ith such issues Goodw in (in press) has

    prop osed that images in interaction are lodged within end ogenous activity

    systems constituted through th e ongoing, changing dep loyment of mu ltiple

    semiotic fields which mutually elaborate each other. The term semiotic field is

    intended to focus on signs-in-their-med ia, i.e., the way in w hich what is typ ically

    been attended to are sign p henomena of various typ es (gestures, maps, displays

    of bodily orientation, etc.) which have variable structural properties that arise in

    part from the d ifferent kind s of materials used to make them visible (e.g., the

    body, talk, documents, etc.). Bringing signs lodged within different fields into a

    relationship of mutu al elaboration produ ces locally relevant meaning and action

    that could not be accomp lished by one sign system alone. Consider for example a

    place on a m ap ind icated by a p ointing finger wh ich is being construed in a

    specific fashion by the accomp anying talk. Neither the map as a w hole, that is a

    self-sufficient representation, nor the pointing finger in isolation from a) its

    target (the spot on th e map ) and b) the construal being p rovided by the talk, nor

    the talk alone w ould be sufficient to constitute the action m ade visible by the

    conjoined use of the three semiotic fields, each of wh ich p rovid es resources for

    specifying how to relevantly see and understand the others (see the brief

    d iscussion of the Rodney King data below for a specific examp le; see Goodwin

    in preparation for more detailed analysis of pointing). The particular subset of

    semiotic fields available in a setting that p articipants orient to as relevant to the

    construction of the actions of the m oment constitutes a contextual configuration.

    As interaction u nfolds contextual configurations can change as new fields are

    add ed to, or d ropp ed from, the specific mix being u sed to constitute the events of

    the moment. Thus, as contextual configurations change th ere is both un folding

    pu blic semiotic structure an d contingency(and indeed in some circum stances

    actions can m isfire when ad dressees fail to take into accoun t a relevant semiotic

    field, such as the sequential organization p rovided by a prior unheard utterance

    see Goodw in in preparation for an examp le).

    Professional Vision

    Work settings provid e one environment in wh ich the interplay between situated,

    embodied interaction, and the u se of visual images of different types, can be

    systematically investigated. In man y w ork settings par ticipants face the task of

    classifying visual phenom ena in a w ay that is relevant to the work they are

    charged w ith performing. Frequently they m ust also construct different kinds of

    representations of visual stru cture in the environment that is the focus of their

    professional scrut iny. We will now briefly examine how such vision is socially

    organ ized in two tasks faced by archaeologists: 1) color classification and 2) Map

    making, and then look at how such professional vision was both constructed and

    contested in the tr ial of four policemen charged w ith beating an African

    American motor ist, Mr. Rodney King. The key eviden ce at the trial was a

    videotape of the beating.

    Color Classification as Historically Structured Professional Practice

    As par t of the work involved in excavating a site, archaeologists make m aps

    showing relevant stru cture in the layers of dirt they uncover. In ad dition to

    artifacts, such as stone tools, archaeologists are also interested infeatures,such the

    remains of an old h earth or the ou tlines of the posts that held up a building. Such

    features are typically visible as color d ifferences in th e dirt being examined (e.g.,

    the remains of a cooking fire will be blacker than the su rroun ding soil, and the

    holes used for p osts will also have a different color from the soil aroun d them).

    Field archaeologists thu s face the task of systematically classifying the color of

    the d irt they are excavating. The m ethods th ey use to accomp lish this taskconstitute a form of professional visual p ractice. As dem onstrated by the

    discussion of Lynchs analysis of scientific representation, and the brief

    description of the oceanograp hers, crucial work in m any different occup ations

    takes the form of classifying and constructing visual p henomena in w ays that

    help shap e the objects of knowledge th at are the focus of the w ork of a profession

    (e.g., architects, sailors plotting courses on charts, air traffic controllers,

    professors making graphs and overheads for talks and classes, etc.). Such

    professional vision constitutes a persp icuou s site for systematic stud y of howdifferent kinds of phenomena intersect to organize a commu nitys practices of

    seeing.

    Goodwin (1996, in press) describes how archaeologists code the color of the

    dirt they are excavating throu gh u se of a Munsell chart. The following show s two

  • 8/3/2019 Handbook of Visual Analysis an Ethnomethodological Approach

    18/40

    17

    archaeologists performing th is task, the Mu nsell page that they are u sing, and

    the coding form where they will record their classification:

    17 Pam: En this one. ((Points at color patch))

    18 (0.4) ((Jeff moves trowel))

    19 Jeff: nuhhh?20 (1.8)

    21 Pam: Or that one? ((Points at color patch))

    Within this scene are a nu mber of different kinds of phenomena relevant to

    the organ ization of visual p ractice, includ ing tools that stru cture the process of

    seeing an d classification, and docum ents that organize cognition an d interaction

    in the current setting w hile linking these p rocesses to larger activities and other

    settings. These archaeologists are intently examining the color of a tiny sam ple of

    d irt because they have been given a coding form to fill out. That form t ies their

    work at th is site to a range of other settings, such as the offices and lab of the

    senior investigator, where the form being filled in here will eventually become

    part of the perm anent record of the excavation, and a componen t of subsequent

    analysis. The multivocality of this form, the way in which it displays on a single

    . 168

  • 8/3/2019 Handbook of Visual Analysis an Ethnomethodological Approach

    19/40

    18

    surface the actions of multip le actors in structura lly d ifferent positions, is show n

    visually in vivid fashion by th e contrast between the printed coding categories,

    and the hand written entries of the field workers.

    The use of a coding form su ch as this to organize the perception of natu re,

    events, or people within the d iscourse of a p rofession carries with it an array of

    perceptual and cognitive operations that have far reaching impact. Coding

    schemes d istributed on forms allow a senior investigator to inscribe his or her

    perceptual d istinctions into the w ork p ractices of the technicians w ho code the

    data. By using such a system a w orker views the world from the perspective it

    establishes. Of all the possible ways that the earth could be looked at, the

    perceptual w ork of field workers using this form is focused on d etermining the

    exact color of a minu te samp le of d irt. They engage in active cognitive work, but

    the p arameters of that work have been established by the classification system

    that is organ izing their perception. In so far as the coding scheme establishes an

    orientation toward the world, a work-relevant w ay of seeing, it constitutes a

    structure of intentionality whose proper locus is not the isolated, Cartesian mind ,

    but a m uch larger organizational system, one that is characteristically m ediated

    through mu nd ane bureaucratic docum ents such as this form.

    Rather than stand ing alone as self-explicating textual objects, forms are

    embedd ed w ithin webs of socially organized, situated practices. In ord er to make

    an entry in the slot provided for coloran archaeologist mu st make u se of another

    tool, the set of standard color samp les provided by a Mu nsell chart. This chart

    incorporates into a portable physical object the resu lts of a long history of

    scientific investigation of the p roperties of color.

    The Mun sell chart being u sed by the archaeologists contains not just on e, but

    three different kind s of sign systems for describing each point in the color space

    it provides: 1) a set of carefully controlled color samples arranged in a grid to

    dem onstrate the changes that result from systematic variation of the variables of

    Hu e , Chroma and Value u sed to d efine each color (each p age displays an

    ordered set of Value and Chroma variables for a single hue); 2) numeric

    coordinates for each row and column , the intersection of what specifies each

    square as a p air of nu mbers (e.g., 4/ 6 on the 10YR Hue page); and 3) standard

    color names such as dark yellowish brown (these names are on the left facing

    p. 169

  • 8/3/2019 Handbook of Visual Analysis an Ethnomethodological Approach

    20/40

    19

    page w hich is not reproduced here). Moreover these systems are not p recisely

    equivalent to each other. For example several color squares can fall within the

    scope of a single nam e.

    Why d oes the Munsell page contain mu ltiple, overlapping representation of

    wh at is app arently the same visual entity (e.g., a par ticular choice within a larger

    set of color categories)? The answer seems to like in the way that each

    representation as a semiotic field with its own distinctive prop erties makes

    possible alternative operations and actions, and thus fits into d ifferent kind s of

    activities. Both the names and nu mbered grid coordinates can be written, and

    thus easily transported from the actual excavation to the other w ork sites, such as

    laboratories and journals, that constitute archaeology as a profession. The

    numbers p rovide the most precise description, and d o not require translation

    from language to langu age. However locating the color indexed by the

    coordinates requ ires that the classification be read with a Mu nsell book at hand .

    By way of contrast the color names can be grasped in a way that is adequate for

    most p ractical pu rposes by any competent sp eaker of the language u sed to write

    the rep ort. The outcome of the activity of color classification initiated by the

    empty square on th e coding form is thu s a set of portable lingu istic objects that

    can easily be incorporated into the u nfolding chains of inscription th at lead step

    by step from the d irt at the site to reports in the archaeological literature.

    How ever, as arbitrary linguistic signs produ ced in a medium that d oes not

    actually m ake visible color, neither the color names nor the num bers, allow d irect

    visual comparison betw een a sam ple of dirt an d a reference color. This is

    precisely what the color patches and viewing h oles make possible. In brief, rather

    than simply specifying unique p oints in a larger color space, the Mun sell chart is

    used in mu ltiple overlapp ing activities (comparing a reference color and a p atch

    of dirt as par t of the work of classification, transpor ting those results back to the

    labe, comparing sam ples, publishing reports, etc.), and thu s represents the

    same entity, a particular color, in multiple ways, each of which makes p ossible

    different kind s of operations because of the unique p roperties of each

    representational system.

    In addition to its various sign system s it also contains a set of circular holes,

    positioned so that one is ad jacent to each color patch. To classify color the

    p. 170

    21/40

    20

    archaeologist puts a sm all samp le of dirt on the tip of a trowel, pu ts the trowel

    directly un der th e Munsell page and then m oves it from hole to hole until the

    best match w ith an adjacent color samp le is found . With elegant simplicity the

    Mun sell page with its holes for viewing the sam ple of dirt on the trow el

    juxtaposes in a single visual field two qu ite different kind s of spaces: 1) actual

    dirt from the site at the archaeologists feet is framed by 2) a theoretical space for

    the r igorous, replicable classification of color. The latter is both a conceptual

    space, the prod uct of considerable research into p roperties of color, and an actual

    physical space instantiated in the orderly m odification of variables arranged in a

    grid on the Mu nsell page. The pages juxtaposing color p atches and viewing holes

    that allow the d irt to be seen right n ext to the color sample provide an

    historically constituted architecture for perception, one that encapsulates in a

    material object theory an d solutions d eveloped by earlier w orkers at other sites

    faced w ith the task of color classification. By juxtap osing unlike spaces, but on es

    relevant to th e accomp lishment of a specific cognitive task, the char t creates a

    new , distinctively hum an, kind of space. It is precisely here, as bits of d irt are

    shaped into the work relevant categories of a specific social group, that nature

    is transformed into culture.

    How are the resources provided by the chart made visible and relevant

    within talk-in-interaction? At line 17 Pam moves her han d to the space above the

    Mun sell chart an d points to a p articular color patch wh ile saying En this one.

    Within th e field of action created by the activity of color classification, what Pam

    does here is not simply an indexical gesture, but a p roposal that the ind icated

    color migh t be the one they are searching for. By virtue of such cond itional

    relevance (Schegloff 1968) it creates a new context in w hich rep ly from Jeff is the

    expected n ext action. In line 19 Jeff rejects the p roposed color. His move occurs

    after a noticeable silence in line 18. However that silence is not an em pty space,

    but a p lace occup ied by its own relevant activity. Before a comp etent answ er to

    Pams prop osal in line 17 can be made, the dirt being evaluated h as to be placed

    un der the viewing hole next to the samp le she indicated, so that the tw o can be

    compared . During line 18 Jeff moves the trowel to this position. Because of the

    spatial organization of this activity, specific actions have to be p erformed before

    a relevant task, a color comparison, can be competently performed. In brief, in

    p. 171

  • 8/3/2019 Handbook of Visual Analysis an Ethnomethodological Approach

    22/40

    21

    this activity the spatial organization of the tools being w orked w ith, and th e

    sequential organization of talk in interaction interact with each other in th e

    prod uction of relevant action (e.g. getting to a place where one m ake an expected

    answer requires rearrangement of the visual field being scrutinized so that th e

    jud gment being requested can be competently p erformed ). Here socially

    organized vision requ ires embod ied manipulation of the environment being

    scrutinized.

    It is comm on to talk about stru ctures such as the Munsell chart as

    representations. How ever exclusive focus on the representational prop erties of

    such structures can seriously distort our u nd erstand ing of how such entities are

    embedd ed w ithin the organization of human p ractice. With its viewholes for

    scru tinizing sam ples, the page is not simp ly a perspicuous rep resentation of

    current know ledge about th e organization of color, but a space designed for the

    ongoing prod uction of particular kinds ofaction.

    We will now look at how a group of archaeologists make a m ap. This process

    will allow us to examine the interface between seeing, writing practices, talk,

    human interaction and tool use (see Goodw in 1994 for more d etailed analysis).

    Map Making and t he Pract ices of Seeing it Requires

    Map s are central to archaeological practice. The p rofessional seeing required to

    prod uce and m ake use of a visual document, such as a map, encompasses notonly the image itself but also the ability to competently see relevant structure in

    the territory being m app ed, mastery of appropriate tools, and on occasion the

    ability to an alyze the w ork-relevant actions of anothers body. These d ifferent

    kinds of phenomena can be brough t together within the temporally unfolding

    process of hu man interaction used to accomp lish the activity of making a map . In

    the following, two archaeologists are making a map to record w hat they have

    foun d in a p rofile of the d irt on the side of one of the square holes they have

    excavated. Before actually setting pen to paper some relevant events in the d irt,such as the bound ary between two different kinds of soil, are highlighted by

    outlining them w ith the tip of a trowel. The structure visible in the dirt is then

    map ped on a sheet of graph pap er. Typically this task is don e by two

    participan ts working together. One u ses a pair of rulers (one laid horizontally on

    the surface, and the other a hand held tape measure used to m easure d epth

    22

    beneath the sur face) to measure the length an d d epth coordinates of the points in

    the dirt that are to be transferred to the m ap, and then speaks these coord inates

    as pairs of numbers (e.g., at fifteen th ree point tw o). The second p erson p lots

    the points specified on th e graph pap er, and d raws lines between successive

    measurements. What w e find here is a small activity system that encomp asses

    talk, writing, tools and distributed cognition as tw o parties collaborate to inscribe

    events they see in the earth onto p aper. Here Ann, the party draw ing the map, is

    the senior Archaeologist at the site, and Sue, the person making measurem ents is

    her Student:

    The sequence to be examined begins with a d irective. Ann, the w riter, tells Sue

    the measurer, to Give me the ground su rface over here to aboutninety.

    How ever before Sue has p roduced any num bers, indeed before she has said

    anything w hatsoever, Ann in lines 4 and 5 challenges her, telling her that what

    she is doing is wrong: No- No- Notat ninety.From you t o about ninety.

    Directives are a classic form of speech action that sociolingu ists have used to

    probe the relationship between language and social structure, and in particular

    issues of power and gender. Here Sue formats both her d irective and her

    correction in very strong, d irect aggravated fashion. No forms of mitigation are

    foun d in either utterance, and Ann is not given an opportun ity to find and

    correct the trouble on h er own. Directives formatted in this fashion h ave

    frequen tly been argu ed to d isplay a hierarchical relationship, i. e., Ann is treating

    Sue as someone that she can give direct, unm itigated ord ers to. And indeed Ann

    is a professor and Sue is her stud ent.

    Issues of power do not how ever exhau st the social phenomena visible in th is

    sequence. Equally imp ortant are a range ofcognitive processes that are as

    socially organized as the relationships between the participants. For example, in

    that Sue has not p rodu ced an answer to the directive, how can Ann see that there

    is something w rong w ith a response that has not even occurred yet? Crucial to

    this process is the ph enomenon ofconditional relevance first described by

    Schegloff (1968). Basically a first ut terance creates an interp retive environm ent

    that w ill be used to an alyze whatever occurs after it. Here no subsequ ent talk has

    yet been produced. How ever, providing an answer in this activity system

    encompasses more than talk. Before speaking the set of nu mbers that counts as a

    prop er next bit of talk, Sue m ust first locate a relevant point in the d irt and

    measure its coordinates. Both her movement throu gh space, and h er use of tools

    such as a tape measu re, are visible events. As Ann finishes her directive Sue is

    holding the tape m easure against the d irt at the left or zero end of the profile.

    How ever, just after hearing ninety Sue m oves both her body and the tape

    measure to right, stopping near the 90 mark on the up per ru ler. By virtue of

    the field interpretation opened u p through cond itional relevance, Sues

    movement and tool use can now be analyzed by Ann as elements of the activity

    she has been asked to p erform, and foun d w anting. Sue has moved imm ediately

    . 173

    25

    to ninety instead of measuring the relevant points between zero and ninety. The

    sequential framew ork created by a directive in talk thu s provid es resources for

    analyzing and evaluating the visible activity of an ad dressees body interacting

    with a relevant environment.

    Additional elements of the cognitive operations and kinds of seeing that Ann

    requires from Sue in order to make her measurements are revealed as the

    sequence continues to unfold. Making the relevant measurements p resupposes

    the ability to locate where in the d irt measurements should be mad e. However

    Sues response calls this presupp osition into question and leads to Ann telling

    her explicitly, in several different w ays, what she shou ld look for in order to

    determine where to measure. After Ann tells Sue to measure points between zero

    and ninety, Sues does not imm ediately move to points in that r egion bu t instead

    hesitates for a full second before replying w ith a w eakOh (line 7). Ann th en

    tells her w hat she shou ld be looking for Wherever theres a change in slope

    (line 8). This description of course presup poses Sues ability to find in the d irt

    wh at will could as a change in slope. Sue again moves her tape measure far to

    the right. At this p oint, instead of relying upon talk alone to make explicit the

    phenomena that she w ants Sue to locate, Ann m oves into the sp ace that Sue is

    attending to and points to one place that should be measured w hile describing

    more explicitly w hat constitutes a change in slope: See so if itsfairlyflat Ill

    need one where itstops being fairly flat like right th ere.

    One of the th ings that is occurr ing within this sequence is a p rogressive

    expansion of Sues und erstanding as the d istinctions she must make to carry out

    the task assigned to her are explicated and elaborated. In th is process of

    socialization th rough language th ere is a growth in intersubjectivity as d omains

    of ignorance that p revent the successful accomplishm ent of collaborative action

    are revealed and transformed into practical knowledge, a way of seeing, that is

    sufficient to get the job at hand don e, such that Sue is finally able to un derstand

    wh at Ann is asking h er to do (that is to see the scene in front of her in a manner

    that p ermits her to m ake an ap prop riate, comp etent response to the d irective). It

    wou ld how ever be wrong to see the un it within which this intersubjectivity is

    lodged as simply these two mind s coming together in the work at han d. Instead

    the d istinction being explicated, the ability to see in the very complex perceptual

    field provid ed by the landscape they are attending to, those few events that

    coun t as points to be transferred to the m ap, are central to wh at it means to see

    the world as an archaeologist, and to use that seeing to bu ild the artifacts, such as

    this map , which are constitut ive of archaeology as a profession. Such seeing

    wou ld be expected of any competent archaeologist. It is an essential part of what

    it means to be an archaeologist, and it is these professional p ractices of seeing

    that Sue is being held accountable to. The relevant unit for the analysis of the

    intersu bjectivity at issue here the ability of separate ind ividu als to see a

    comm on scene in a congru ent, work-relevant fashion is thus not these

    individuals as isolated entities, but instead archaeology as a profession, a

    comm un ity of comp etent practitioners, most of whom have never m et each

    other, but w ho n onetheless expect each other to be able to see and categorize the

    wor ld in w ays that are relevant to the w ork, scenes, tools and ar tifacts that

    constitute their profession.

    The ph enomena examined so far provide some demonstration of how what is

    to be seen in a m ap, scene, hum an bod y or image stand s in a reflexive

    relationship to other semiotic structures that p articipants are u sing to constitute

    visual phenom ena as a relevant component of the events and activities that make

    up their lifeworld . These structures includ e language, the constitution of action

    and context provid ed by sequen tial organization, and ways of seeing events and

    using images of d ifferent typ es that are lodged w ithin the p ractices of particular

    social commu nities, such as the profession of archaeology.

    Professional Vision in Court

    Parties who are not competent m embers of relevant social comm unities can lack

    the ability, and/ or the social positioning, to see and articulate visual events in a

    consequential way. These issues were mad e d ramatically visible in the trial of

    four Los Angeles policemen w ho were recorded on v ideotape ad ministering a

    beating to an African American motorist, Mister Rodn ey King, whom they hadstopped after a high speed p ursu it triggered by a traffic violation. When the tape

    of the beating was show n on n ational television there was outrage, and even the

    head of the Los Angeles police d epartm ent thought that conviction of the officers

    was almost autom atic. How ever, at their first trial (they w ere later tried again in

    Federal ra ther than state cour t for violating Mister Kings civil rights) all fourp. 175

  • 8/3/2019 Handbook of Visual Analysis an Ethnomethodological Approach

    28/40

    27

    policemen w ere acquitted, a verdict that triggered an u prising in the city of Los

    Angeles, with neighborhood s being burn ed, federal troops being called in, etc.

    The crucial evidence at the trial was a visual d ocum ent: the videotape of the

    beating. Rather than transparently proving the guilt of the policemen w ho were

    seen on it beating a man lying p rone on the groun d, the tape in fact provided the

    policemens lawyers w ith their evidence for convincing the jury that th eir clients

    were not gu ilty of any w rongd oing. They did this by using langu age, pointing

    and expert testimony to structure how the jury saw the events on the tape in a

    way the exonerated the p olicemen. In essence they used the tap e of the beating to

    dem onstrate that Mr. King w as the aggressor, not the p olicemen, and that the

    policemen w ere following prop er police practice for subd uing a violent,

    dan gerous su spect (see Goodwin 1994 for more d etailed analysis of such

    professional vision). Crucial to their success was their use of another policeman,

    Sargent Du ke, as an expert witness. It was argued that laymen could n ot

    prop erly see the events on the tap e. Instead, the ability to legitimately see wh at

    the body of a suspect was d oing, such as Mr. Kings as he lay on the ground

    being beaten, and specifically whether th e suspect w as being aggressive or

    comp liant, was lodged w ithin the work practices of the social group charged

    with arresting susp ects: the p olice. The ability to see such a body, and code it in

    terms of its aggressiveness, was a component of the professional practices that

    policemen u se to code the events that are the focus of their w ork. It so far as such

    vision is a pu blic comp onent of the work p ractices of a p articular social group ,

    someone wh o wasnt present bu t who is a member of the profession, a

    policeman, can m ake auth oritative statements abou t what can be legitimately

    seen on th e tape. How ever, while policemen constitute a socially organized

    profession, susp ects and victims of beatings d ont. Therefore there is no one with

    the social stand ing, i.e., mem bership and mastery of the practices of a relevant

    social group , to act as an expert w itness to articulate what w as happening from

    Mister Kings p erspective.

    What was to be seen on the tape was structured through the way in w hich

    different semiotic fields, such as structure in the stream of speech, pointing

    wh ich h ighlighted specific places and phenomena in the image being looked at,

    and events in the image itself, mu tually elaborated each other to p rovide a

  • 8/3/2019 Handbook of Visual Analysis an Ethnomethodological Approach

    29/40

    28

    construal of events that served the pu rposes of the party articulating the image.

    The following p rovides an examp le. At the p oint wh ere we enter th is sequence

    the prosecutor has noted that Mr. King ap pears to be moving into a position

    app ropriate for han dcuffing him, and that on e officer is in fact reaching for his

    han dcuffs, i.e. the su spect is being cooperative.

    1 Prosecu tor: So uh would you ,

    2 again consider this to be:

    3 a nonagressive, movement by Mr. King?

    4 Sgt. Duke: At this t ime no I wouldn't. (1.1)

    5 Prosecutor : It is aggressive.

    6 Sgt. Duke: Yes. It 's starting to be. (0.9)

    indicates that Sgt. Duke is pointing on the screenat the body part described in his talk.

    By noting the submissive elements in Mr. Kings posture, and the fact that one of

    the officers is reaching for his handcuffs the prosecutor has shown that th e tape

    demon strates that Mr. King is being cooperative. If he can establish this point

    hitting Mr. King again would be un justified, and the officers should be found

    guilty of the crimes they are charged with. The contested vision being d ebated

    here has very h igh stakes.

    To rebut the vision p roposed by the p rosecutor, Sgt. Duke uses the seman tic

    resources provided by language to code as aggressive extremely subtle body

    movements of a man lying face down beneath the officers (lines 7-11). Note for

    examp le not only line 13s explicit placement of Mr. King at the very edge, the

    beginning, of an aggressive spectrum introdu ced in earlier testimony, but also

    p. 176

  • 8/3/2019 Handbook of Visual Analysis an Ethnomethodological Approach

    30/40

    29

    how very small movements are made mu ch larger by situating them w ithin a

    prosp ective horizon through the repeated u se ofstarting to (lines 6, 8, 13). The

    events visible on the tape are structured, enhanced and amp lified by the

    language used to describe them.

    This focusing of attention organizes the p erceptu al field p rovided by the

    videotape into a salient figure, the aggressive susp ect, wh o is highlighted against

    an am orphous backgroun d containing nonfocal participan ts, the officers doing

    the beating. Such stru cturing of the materials prov ided by the image is

    accomp lished n ot only through talk, but also through gesture. As Sergeant Duke

    speaks he brings his hand to the screen and points to the par ts of Mr. Kings

    body that he is arguing d isplay aggression. The pointing gesture and the

    perceptual field wh ich it is articulating m utu ally elaborate each other. The

    touchable events on the television screen provide visible evidence for the

    description constructed th rough talk. What emerges from Sgt. Dukes testimony

    is not just a statement, a static category, but a demonstration built through the

    active interplay between coding scheme and the image to w hich it is being

    app lied. As talk and image mu tually enhance each other a demonstration that is

    greater than th e sum of its parts em erges, while simultaneously Mr. King, rather

    than the p olice officers becomes the focus of attention as the experts finger

    articulating the image delineates what is relevant w ithin it.

    By virtue of the category system erected by the defense, the minu te rise in Mr.

    Kings buttocks noted on the tape u nleashes a cascade of perceptual inferences

    that have the effect of exonerating the offers. A rise in Mr . Kings body becomes

    interp reted as aggression, which in tu rn justifies the escalation of force. Like

    other p arties, such as th e archaeologists, faced with the task of coding a visual

    scene, the jury was led to engage in intense, minute cognitive scrutiny as they

    looked at the tap e of the beating to decide the issues at stake in the case.

    How ever, once the d efense coding scheme is accepted as a relevant framework

    for looking at the tap e, the operative perspective for viewing it is no longer a

    laypersons reaction to a man lying on the grou nd being beaten, but instead a

    micro-analysis of the movements being m ade by that m ans bod y to see if it is

    exhibiting aggression.

    In the first trial, though the p rosecution dispu ted the an alysis of specific body

    movements as d isplays of aggression, the relevance of looking at th e tape in

    terms of such a category system w as not challenged . A key d ifference in the

    second tr ial, which led to the conviction of two of the officers, was th at there the

    prosecution gave the jury alternative frameworks for interp reting the events on

    the tap e. These included ways of seeing the m ovements of Mr. Kings body that

    Sgt. Duke highlighted as normal reactions of a man to a beating rather than as

    displays of incipient aggression. In the prosecutions argum ent Mr. King cocks

    his leg, not in p reparation for a charge, but because h is muscles natu rally jerk

    after being hit w ith a m etal club.

    The stud y of the p ractices used to structure relevant vision in scientific and

    workplace environments, what H utchins (1995) has called Cognition in the Wild,

    has become the focus of considerable research. A major initiative for such studies

    was provided by Lucy Scuhman in th e early 1990s when she initiated the

    Workp lace project while at Xerox PARC. The site chosen for research w as

    groun d op erations at a mid-sized airport. Docum ents and images of many

    different types, and the ability of actors in alternative structural positions to see

    and analyze events in relevant w ays, were crucial to the work of the airport.

    Phenomena that received extensive stud y includ ed w ork relevant seeing of

    docum ents, airplanes and events (Goodw in and Goodw in 1996), the constitution

    of shared workspaces (Suchman 1996), the stud y of how a common docum ent

    coordinated different kinds of work in different w ork settings, and the p ractices

    involved in seeing and shaping p henom ena in collaborative work (Suchman and

    Trigg 1993, Bru n-Cottan 1991). In part because of the central role played by

    visual phenom ena in the work being analyzed, the projects final report w as

    submitted as a videotape (Brun-Cottan et al. 1991). Subsequent analysis growing

    from this project has focused on th e organization of both d ocuments and visual

    phenomena in a range of occupational settings, such as law firms and th e work

    of architects. In England Christian Heath and his collaborators have investigated

    the structuring of vision w ithin interaction in a ran ge of settings includ ing the

    control room for the Lond on Und erground, centers for the produ ction of

    electron ic news, ar t classes, etc. (Heath and Luff 1992, 1996, Heath and Nicholls

    1997). In much of th is research there is a focus on h ow core practices for the

  • 8/3/2019 Handbook of Visual Analysis an Ethnomethodological Approach

    32/40

    31

    organization of talk, reference, gesture and other p henomena central to the

    prod uction of action within hum an interaction can encompass not only talk but

    also embod iment in a world p opu lated by work-relevant objects. Hinderm aash

    and Heath (in p ress) investigate reference within su ch a framew ork. LeBaron

    (1998), Streeck (1996) and LeBaron and Streeck (in p ress) examine how gesture

    emerges from the interaction of working h and s acting in th e world in settings

    such as architects meetings and auto body shops. Robinson (1998) has provided

    analysis of participants in m edical interviews organize their interaction by

    attending to how gaze is shifted from other participants to relevant visual

    materials in the setting, such as medical records. Whalen (1995) analyzed how

    the talk of operators respond ing to emergency 911 calls was organized in part by

    the task of filling in requ ired information on a computer screen w ith a sp ecific

    visual organization. Rogers Hall and Reed Stevens have investigated visual

    practices in a ran ge of school, scientific and occup ational settings (Hall and

    Stevens 1995; Stevens an d H all in p ress). Research in Compu ter Supp orted

    Cooperative Work h as focused sp ecifically on new form s of visual access created

    by electronic media. Heath (in p ress) and Heath and Luff (1993) have d one

    considerable research on interaction mediated th rough video, demonstrating the

    crucial ways in w hich resources available to parties who are actually co-present

    to each other are not available in media spaces. Yamazaki and his

    colleagues,have explored the systematic problems that arise when p articular

    kinds of d irectives, such as instructions for how to use CPR to start a h eart attack

    victims heart, are given through talk alone, for example over the p hone, without

    access to a relevant visual environment. Patients usually die, since the novice is

    not able to place his or her hand s at the appropriate spot on the patients body.

    To remedy som e of these issues technologies that incorporate basic resources

    available for doing reference in face-to-face interaction, such as p ointing, have

    been developed . These include a remote controlled car w ith a laser that has the

    ability to move while clearly marking the specific places being pointed at in a

    remote environ ment (Yamazaki et al. 1999). Nishizaka (in press) has investigated

    how par ticipants coordinate gaze both sp atially and temporally on electronic

    docum ents such as compu ter screens. Kawatoko (in p ress) has investigated how

    lathe workers organize p erceptu al fields so to make visible the invisible

    p. 178

    33/40

    32

    movements of their cutting tools.. Both Kwatoko and Ueno (in press) have

    examined the organization of vision on m any d ifferent levels (from docum ents to

    systematic placement of objects on the warehouse floor as part of its work flow)

    in the w ork p ractices of large warehouse. In all of this work p ractices for seeing

    relevant p henomena are systematically embedd ed within processes of social

    organization, structures of mu tual accoun tability and the organ ization of activity.

    Conclusion

    Within both Conversation Analysis and Ethnomethod ology visual phenom ena

    have been analyzed by investigating how th ey are made m eaningful by being

    embedd ed w ithin the practices that p articipants in a var iety of settings use to

    construct the events and actions that m ake up their lifeworld. This has led to the

    detailed stud y of a range of quite different kinds of phenom ena, from th einterplay between gaze, restarts and gramm ar in the building of utterances

    within conversation, to the construction and use of visual representations in

    scientific practice, to how the ability of lawyers to shap e wh at can be seen in the

    videotape of policemen beating a suspect can contribute to d isruption of the

    body politic that leaves a city in flames, to the part played by visual practices in

    both trad itional and electronic workp laces. Visual phenomena that h ave received

    particular atten tion include 1) the body as a visible locus for disp lays of

    intentional orientation throu gh both gaze and postu re; 2) the body as a locus for

    a variety of different kinds of gesture, from iconic elaboration on w hat is being

    said in the stream of speech, to pointing, to the hand as an agent engaged with

    the world arou nd it; 3) visual documents of man y different types used in both

    scientific practice and the w orkp lace, e.g., maps, grap hs, Mun sell charts, coding

    forms, schedules, television screens providing access to distant sites,

    architectural d rawings, comp uter screens, etc. 4) material structure in th e

    environment where action and interaction are situated. This perspective brings

    together within a common analytic framework both the d etails of how the visible

    body is used to build talk and action in moment to moment interaction, and the

    way in w hich h istorically structured v isual images and features of a setting

    participate in that process. Rather than standing alone as self-contained, self-

    explicating images, visual phenom ena become meaningful throu gh the way in

    wh ich th ey help elaborate, and are elaborated by, a range of other semiotic fields

    sequential organization, structure in the stream of speech, encompassing

    activities, etc. that are being used by par ticipants to both construct and make

    visible to each other relevant actions. The focus of analysis is always on how the

    participan ts in a setting themselves display a consequential orientation to v isual

    phenomena (e.g., by shifting gaze after a restart, focusing th eir work on a

    Mun sell chart, building images as a core comp onent of the p ractices used to

    make visible scientific phen omen a, etc.). A var iety of different m ethod ologies are

    employed. How ever a basic comp onent of many research p rojects includ es going

    to the site where th e activities being investigated are actually performed, an d

    examining wh at the p articipants are doing th ere as carefully as possible.

    Videotap e records are frequently m ost useful because of the way in which they

    preserve limited but crucial aspects of the spatial and environmental features of a

    setting, the tem poral u nfolding organization of talk, the visible displays of

    participants bodies, and changes in relevant phenomena in the setting as

    relevant courses of action unfold. Analysis typically requires not only viewing

    the tape, ethnograph ic records and docum ents collected in a setting, but also the

    construction of new visual representations such as tran scripts of many d ifferent

    types (note how some in this pap er incorporate both d etailed transcription of the

    talk and a var iety of different kind s of graph ic representations). While this

    analysis sheds mu ch important new light on how visual ph enomena are

    organized throu gh systematic discursive practice, it is not restricted to vision per

    se but is instead investigating the m ore general practices used to build action

    within situated human interaction.
