EDITORIAL
Our Vision for Autism Research
One dilemma facing all researchers is the choice of where
to submit their next paper. The scientific content of a
Journal, its readership, impact factor, the speed of
publication and how editors dealt with previous submis-
sions are some of the factors that authors consider when
choosing a venue for their manuscript. In launching a
new publication, editors should convey to potential
authors the essence of a Journal in order to attract those
papers that will establish its future character. In introdu-
cing this second issue we articulate some of the editorial
considerations underlying publication priorities.
Autism Research was established by the International
Society for Autism Research (INSAR) to satisfy the
pressing need for a publication outlet for high quality
papers dealing with the full range of basic and beha-
vioural sciences that underlie research into autism
spectrum disorders. The Journal is also an important
vehicle for INSAR, whose aim is to advance autism
research. The Editors recognize that these goals are well
served by publishing both positive and negative findings.
Exciting new findings, especially from hypothesis driven
research, are the bread and butter of scientific journals,
and they are sought for this journal as well.
Nevertheless, research into autism is also marked by
intriguing findings that have been neither replicated nor
refuted, either because replication has never been
attempted or because a failure to replicate has not been
published. Consequently, in order to support new
hypotheses or new data, authors may refer to unrepli-
cated findings, which may simply be false positives.
Scientific advance in part requires identifying those
hypotheses that are not supported by empirical data
and on the publication of definitive negative studies.
There is usually a bias against the publication of negative
findings in research. The field of autism research is one
with a large, potentially vulnerable lay audience that
actively follows research. Therefore, the Editors consider
it important to publish both replications and non-
replications to foster the ultimate emergence of a
balanced picture.
At times, the pressure to report positive findings in the
face of nonsignificant results from primary analyses may
lead authors to perform ad hoc analyses to support an
auxiliary hypothesis. Thus, a hypothesis that is refuted in
the main finds support in a subgroup of data. Determin-
ing scientific merit in such cases can be difficult for
reviewers and Editors because the findings may help
describe true heterogeneity, or they may be spurious.
Subgroup analyses planned a priori, statistical limitations
created by subdividing data and plausibility are all factors
that help assess validity in such cases.
Statistical power is an important concern, and some
studies lack statistical power at the outset. The issue is
particularly problematic with respect to genetic studies,
in which associations observed in modest-sized samples
are given undue weight; these issues will be discussed in
more detail in a future editorial. For this reason, we ask
authors to provide a statement regarding power in all
submitted manuscripts. Studies that are preliminary, or
perhaps out of necessity under-powered, should be
submitted as short reports and these limitations noted.
Another phenomenon in autism research over the
decades has been a tendency for some influential
hypotheses to lack explanatory power. Autism is a
complex disorder involving both deficits in multiple
domains of functioning and a very wide range of severity.
Authors should to state clearly which aspects of ASDs
their hypotheses and data address and which aspects of
the disorder and its full range of expression are not
accounted for.
The phenomenon of ‘‘selective referencing’’ is a
troubling issue for scientific publishing in general.
Examples include instances in which manuscripts con-
tain only citations that support the authors’ views or
referencing may appear to over-represent subset of
groups, perhaps even driven by geography. Neither
scenario provides a fair and balanced basis upon which
a proper judgement can be made about the merits of a
given study. Referencing should be broadly inclusive.
Both supportive and contradictory citations and text
should be provided to the reader to place the study at
hand in a balanced context.
What sort of papers would Autism Research like to
publish? In addition to definitive advances in specific
areas, manuscripts that address the complexity and
heterogeneity in autism directly, or contribute to its
understanding seem likely to move the field forward.
Another variable that is often neglected in studies is
variation in severity of phenotypic expression. Reliably
measuring symptom severity, and hence identifying
neurobiological and psychological differences across the
spectrum, is likely to contribute to identification of

different aetiological factors, advances in treatment and
preventative strategies. Another neglected area is the
consideration of developmental processes in neurobiolo-
gical research. While psychological studies of autism are
often intrinsically developmental in their approach, our
understanding of neurobiology comes largely from
studies of adult humans and animals. A proper under-
standing of ASDs requires identifying the neurobiological
changes that accompany development.
The last decade has seen a huge expansion in molecular
and statistical genetic studies of autism. Although there is
much interest in relating genetic variation to specific
behavioural phenotypes, it is equally important to
understand the impact of genetic variation on brain
structure and function, particularly at the cellular level.
Changed attitudes to post-mortem studies of autism will
hopefully lead to an increasing number of submissions in
this area. But it will also be important to model the
consequences of genetic change in animal systems,
which involves assessing the relevance of the specific
model. This is perhaps more straightforward when an
animal model replicates specific genetic variation found
in people with ASDs. However, assessing the validity of
animal models of neuropathology or behavioural ab-
normalities without a clear and direct genetic link is
intrinsically more problematic and should be carefully
addressed by authors.
Publishing treatment research is not currently a
priority for this Journal, as this area is well provided for
by other titles. The exception to this general rule is when
an intervention reveals an important aspect of under-
lying mechanisms. This type of data would be especially
welcomed by the Journal. The Editors recognize that
scientific research does not occur in a political and
sociological vacuum, thus we welcome editorial articles
that deal cogently with funding, ethical and public
health concerns that have broad implications for the
field. If potential authors wish to determine the suit-
ability of specific manuscripts for this Journal, they
should contact any member of the Editorial team for a
discussion.
Finally, we will seek scholarly reviews of important
topics for each issue. These are solicited by the Editors
from leading experts in the field, but may also be
submitted as an unsolicited manuscript. If you wish to
provide a review, please first contact one of the editors to
discuss the idea and determine its relevance to the
journal.
To end, we are extremely pleased by the response of the
scientific community to the new Journal. Two issues have
now been published. They are available on the internet
and will soon arrive in your mailbox. Thank you for
submitting your work, and please continue. We hope that
the guidelines offered above help authors decide what
manuscripts to submit to Autism Research. In addition, we
seek feedback from you, the readers, of these first two
issues, about the complexion of the journal thus far, and
your reactions to the direction it is taking.
