We investigated the perception of illusory contours in infants with high-risk of Autism spectrum disorder (ASD) who had siblings with ASD and that in infants without the risk of ASD who had no siblings with ASD. The infants without the risk of ASD (6-8 months of age, n=13) showed a significant visual preference for illusory contour figures (IC) against the figures that had no illusory contour. On the contrary, the high-risk infants (6-8 months of age, n=16) showed no significant visual preference for the IC figures. Additionally, although fourteen of the high-risk infants were tested again at 11-13 months of age, they showed no significant preference for the IC figures. The difficulty of the high-risk infants in detection of the IC figures may be a specific trend in visual perception of infants with high-risk of ASD.
