Perception of talker age by young adults with high-functioning autism

People with high-functioning Autism (HFA) can accurately identify social categories from speech, but they have more difficulty connecting linguistic variation in the speech signal to social stereotypes associated with those categories. In the current study, the perception and evaluation of talker age by young adults with HFA was examined. The participants with HFA performed similarly to a typically-developing comparison group in age classification and estimation tasks. Moreover, the participants with HFA were able to differentiate among talkers of different ages in a language attitudes task and rated older talkers as more intelligent than younger talkers. These results suggest that people with HFA are able to make reasonable social judgments about talkers based on their speech, at least for familiar social categories and personally relevant social attitudes.
