Research Abstract

Patients with Asperger syndrome suffer from severe impairment in social cognition despite their intellectual ability comparable to matched controls. The present research investigated their ability to recognize emotional information from subliminally or supra-liminally presented social stimuli. The results revealed that adults with Asperger syndrome rely on peculiar cognitive strategy in recognizing facial expressions. The present study has also identified an event-related potential that reflects cross-modal integration between emotional prosody and subliminally presented facial expression.
