Color Afterimages in Autistic Adults
Maule, John; Stanworth, Kirstie; Pellicano, Elizabeth; Franklin, Anna
Journal of Autism and Developmental Disorders, v48 n4 p1409-1421 Apr 2018
It has been suggested that attenuated adaptation to visual stimuli in autism is the result of atypical perceptual priors (e.g., Pellicano and Burr in "Trends Cogn Sci" 16(10):504-510, 2012. doi:10.1016/j.tics.2012.08.009). This study investigated adaptation to color in autistic adults, measuring both strength of afterimage and the influence of top-down knowledge. We found no difference in color afterimage strength between autistic and typical adults. Effects of top-down knowledge on afterimage intensity shown by Lupyan ("Acta Psychol" 161:117-130, 2015. doi:10.1016/j.actpsy.2015.08.006) were not replicated for either group. This study finds intact color adaptation in autistic adults. This is in contrast to findings of attenuated adaptation to faces and numerosity in autistic children. Future research should investigate the possibility of developmental differences in adaptation and further examine top-down effects on adaptation.
