Local and global process of stimuli in autism using face

Abstract

The aim of the study was how people with autism configure faces. We collected data from autistic and normal children. In a lighted room participants were presented with 24 stimuli constructed by three dots configuring a face. Stimuli were provided in upright or inverted and symmetric or asymetric, which are determined by the relative distances and positions among dots making either face or no face. The error rate was measured. The results showed that autistics showed a significant error when the face stimili were presented inverted fashion, suggesting that they focused on local feature in face processing.
