Response to familiar faces , newly familiar faces , and novel faces as assessed by ERPs is intact in adults with autism spectrum disorders . Individuals with autism spectrum disorders ( ASD ) have pervasive impairments in social functioning , which may include problems with processing and remembering faces . In this study , we examined whether posterior ERP components associated with identity processing ( P2 , N250 and face-N400 ) and components associated with early-stage face processing ( P1 and N170 ) are atypical in ASD . We collected ERP responses to a familiar repeated face ( Familiar ) , an unfamiliar repeated face ( Other ) and novel faces ( Novels ) in 29 high-functioning adults with ASD and matched controls . For both groups , the P2 and N250 were sensitive to repetition ( Other vs. Novels ) and personal familiarity ( Familiar vs. Other ) , and the face-N400 was sensitive to repetition . Adults with ASD did not show significantly atypical processing of facial familiarity and repetition in an ERP paradigm , despite showing significantly poorer performance than controls on a behavioral test of face memory . This study found no evidence that early-stage facial identity processing is a primary contributor to the face recognition deficit in high-functioning ASD .
