Progress in psychological science can be limited by a number of factors, not least of which are the starting assumptions of scientists themselves. We believe that some influential accounts of autism rest on a questionable assumption that many of its behavioral characteristics indicate a lack of social interest – an assumption that is flatly contradicted by the testimony of many autistic people themselves. In this article, we challenge this assumption by describing alternative explanations for four such behaviors: low levels of (...) eye contact, infrequent pointing, motor stereotypies, and echolalia. The assumption that autistic people's unusual behaviors indicate diminished social motivation has had profound and often negative effects on the ways they are studied and treated. We argue that understanding and supporting autistic individuals will require interrogating this assumption, taking autistic testimony seriously, considering alternative explanations for unusual behaviors, and investigating unconventional – even idiosyncratic – ways in which autistic individuals may express their social interest. These steps are crucial, we believe, for creating a more accurate, humane, and useful science of autism. (shrink)

In response to the 32 commentaries, we clarify and extend two of the central arguments in our target article: Social motivation is a dynamic, emergent process, not a static characteristic of individuals, and autistic perspectives are essential to the study of autistic social motivation. We elaborate on how taking these two arguments seriously can contribute to a more accurate, humane, and useful science of autism.

Alexithymia is a subclinical trait involving difficulty describing and identifying emotions. It is common in a number of psychiatric conditions. Alexithymia in children is sometimes measured by parent report and sometimes by child self-report, but it is not yet known how closely related the two measures are. This is an important question both theoretically and practically, in terms of research design and clinical practice. We conducted a preliminary study to investigate this question in a sample of 6- to 11-year-old neurotypical (...) children and their parents. Parent and child reports were not correlated, and 93% of parents under-estimated their child’s level of alexithymia relative to the child’s self-report. Based on these results, we hypothesize that when asked to report on the child’s alexithymia, children and parents may not be reporting on the same phenomenon, and thus these two measures may not be interchangeable. These provocative findings, however, must be considered preliminary: our analyses were sufficiently powered to detect a strong relation between the two types of report had one existed, but our analyses were not sufficiently powered to distinguish between a small relation and no relation at all.
