Familiar face recognition in children with autism; the differential use of inner and outer face parts

Abstract

We investigated whether children with autistic spectrum disorders (ASD) have a deficit in recognising familiar faces. Children with ASD were given a forced choice familiar face recognition task with three conditions: full faces, inner face parts and outer face parts. Control groups were children with developmental delay (DD) and typically developing (TD) children. Children with ASD and children with DD recognised slightly fewer faces than did TD children, but there was no ASD-specific deficit. All groups displayed the dame pattern of face part superiority: full-face superiority over inner face, and inner face superiority over outer face. Thererfore, the pattern of familiar face recognition by children with ASD was similar to the pattern found in other children.
