SPLLOC 2

Main Goal: to test the validity of the Aspect and the Discourse Hypotheses with reference to the acquisition of perfective and imperfective forms in L2 Spanish.

Relevant features:

1. Cross-sectional design with native speaker controls

2. A combination of different task types

3. Data available online for use by other researchersAudio files (mp3 & .wav)

Transcripts (CHILDES)

Tagged files (MOR)

Perfective and Imperfective forms in Spanish Perfective (preterit): bounded

Llegué tarde. (I arrived late.) Preparaste el almuerzo. (You prepared lunch.) Ella pintó. (She painted).

Imperfective (imperfect): unbounded Llegaba tarde. (I would arrive late/was arriving late) Ella preparaba el almuerzo cuando … (She was

preparing lunch when…) Estaban cansados. (They were tired)

SPLLOC 2 Research Questions:

1. Emergence: What is the pattern of Tense-Aspect development of English L2 learners of Spanish?

2. AH VS DH: Can the observed pattern be accounted for by the Aspect Hypothesis, the Discourse Hypothesis, or both?

3. Acquisition of Imperfective Semantic meanings: Which reading is the imperfect associated with in the first place (habitual, continuous, progressive)?

Page 6: Task Design in L2 Tense and Aspect Research: What matters? Nicole Tracy-Ventura Laura Dominguez University of Southampton Contact email: N.Tracy-Ventura@soton.ac.uk

L2 Tense and Aspect Research

Various hypotheses proposed to explain the L2 acquisition of tense-aspect morphology. For example: Aspect Hypothesis (Andersen & Shirai, 1994,1996) Discourse Hypothesis (Bardovi-Harlig, 1998) Default Past Tense Hypothesis (Salaberry, 1999, 2008) Distributional Bias Hypothesis (Andersen, 1994) Minimalist Hypothesis (Montrul & Slabakova, 2002)

Despite a large body of research, still several issues to be resolved: Inconclusive results when comparing competing hypotheses

(AH vs. DH). Acquisition of the imperfective has not been adequately

addressed (Bardovi-Harlig, 2005).

Page 7: Task Design in L2 Tense and Aspect Research: What matters? Nicole Tracy-Ventura Laura Dominguez University of Southampton Contact email: N.Tracy-Ventura@soton.ac.uk

Aspect Hypothesis(Andersen & Shirai, 1994, 1996)

Perfective and Imperfective morphology emerge in a sequence determined by the inherent semantic properties of the verbal predicate

Achievements (recognize, wake up) Accomplishments (build a house, write a

letter) Activities (swim, walk, sing) States (be, want, love)

Discourse Hypothesis(Bardovi-Harlig 1998)

L2 learners’ use of temporal-aspectual forms is guided by narrative structure

FOREGROUND moves time along chronologically PERFECTIVE

BACKGROUND supporting information, description, evaluation,

prediction IMPERFECTIVE

Page 12: Task Design in L2 Tense and Aspect Research: What matters? Nicole Tracy-Ventura Laura Dominguez University of Southampton Contact email: N.Tracy-Ventura@soton.ac.uk

Studies testing the DH vs. AH

For example: Bardovi-Harlig (1998) Liskin-Gasparro (2000) López-Ortega (2000) Comajoan & Pérez Saldanya (2005) Salaberry (2009)

Results complicated because the cases where the hypotheses make opposite predictions have been difficult to elicit using more free and open-ended tasks Non-Prototypical Pairings

Page 13: Task Design in L2 Tense and Aspect Research: What matters? Nicole Tracy-Ventura Laura Dominguez University of Southampton Contact email: N.Tracy-Ventura@soton.ac.uk

What about the ‘elusive imperfect’?(Bardovi-Harlig, 2005)

The imperfect has multiple semantic interpretations but research has rarely taken this into consideration. (e.g., habitual, progressive, continuous)

Are there meanings of the imperfect acquired before others?

Page 14: Task Design in L2 Tense and Aspect Research: What matters? Nicole Tracy-Ventura Laura Dominguez University of Southampton Contact email: N.Tracy-Ventura@soton.ac.uk

In sum

Various hypotheses have been proposed to explain the acquisition of past tense morphology. How do we make sense of all the results?

Ayoun & Salaberry (2005) suggest that it’s not that one hypothesis is right and another is wrong. Each hypothesis might explain a different stage of development.

However, What if our elicitation tasks are to blame? Most studies have not designed tasks considering

prototypical and nonprototypical forms and discourse role.

Page 15: Task Design in L2 Tense and Aspect Research: What matters? Nicole Tracy-Ventura Laura Dominguez University of Southampton Contact email: N.Tracy-Ventura@soton.ac.uk

Elicitation Tasks in Tense-Aspect Research

Oral: Personal narratives Impersonal narratives

(e.g., Modern Times) Role-plays Interviews and semi-

structured interviews Free conversation

Written: Personal narratives Impersonal narratives Essays/compositions Multiple choice Fill-in-the-blank Appropriateness

judgments Sentence conjunction

*Most studies use one or two task types, not a range.

Page 16: Task Design in L2 Tense and Aspect Research: What matters? Nicole Tracy-Ventura Laura Dominguez University of Southampton Contact email: N.Tracy-Ventura@soton.ac.uk

Issues with Tasks

Problems eliciting past tense morphology with prompts such as “What happened in the story”: Learners and NS use historical present Learners and NS focus on main events, i.e.,

foreground and not as much on background.

Few nonprototypical pairings occur naturally Lafford (1996) no nonprototypical imperfect

pairings

Page 17: Task Design in L2 Tense and Aspect Research: What matters? Nicole Tracy-Ventura Laura Dominguez University of Southampton Contact email: N.Tracy-Ventura@soton.ac.uk

Task type can affect:

1. amount of lexical diversity Film retells – much higher percentage of achievement verbs than

the three other lexical aspect classes (Bardovi-Harlig, 2000)

2. amount of foreground and background Impersonal narratives – more examples of foreground than

background (Liskin-Gasparro, 2000). personal narratives – usually less constrained and often include

more background (Bardovi-Harlig, 2005).

3. rates of appropriate use Learners most accurate with cloze tests, then written retells, then

spoken retells (Bardovi-Harlig, 1998; Camps, 2002)

Page 18: Task Design in L2 Tense and Aspect Research: What matters? Nicole Tracy-Ventura Laura Dominguez University of Southampton Contact email: N.Tracy-Ventura@soton.ac.uk

Conclusions

Need tasks that accomplish the following: naturally elicit the past tense elicit a variety of verb types in both prototypical and

nonprototypical pairings. are rich in background (vs. foreground). elicit the imperfect with different meanings (habitual,

progressive, continuous).

Need to have the same learners (across proficiency levels) do a variety of text and task types: Narratives, description, biographical controlled vs. less controlled production and comprehension

Preliminary Results

Tasks were successful at eliciting past. Pictures worked well for eliciting different

lexical aspect classes and habitual/progressive events.

More equal amounts of foreground/background elicited in the narratives.

Next steps in analysis

Finish coding all tasks Consider across-group and within-group

results for evidence of developmental stages Compare learners’ use of imperfect

morphology on production tasks with the results of the comprehension task

Compare learners’ performance across production tasks

TBLT Implications

Past tense morphology is a developmental feature.

When designing tasks: pay attention to the verb phrases used

Are there both prototypical and nonprototypical pairings?

consider the amount of foreground and background.

Try to include equal amounts think about how useful prompts are use various text and task types
