Abstract:
Clinical intuition and resent research (Senju et al., 2009) suggests that adults with high-functioning autism (HFA) are able to use explicit verbal information but fail to react upon subtle nonverbal cues in order to understand others and navigate social encounters.In order to investigate the relative influence of different domains of socially relevant information in HFA as compared to matched controls, we used verbal and nonverbal stimuli as a basis for an interpersonal impression formation task. Results demonstrated a reduced sensitivity to nonverbal cues in individuals with HFA when consideration of conflicting information from the different domains was required, although HFA participants could well evaluate nonverbal stimuli in isolation. Thus, in a more complex experimental setting nonverbal information had a comparably weak impact on the impression formation confirming that social processing is preferentially based on verbal information in HFA.
