Colour and autism spectrum disorders
-
Anna Franklin
Abstract
There is converging evidence for atypical perception in those with Autism Spectrum Disorders (ASD). This chapter reviews a series of studies that have initiated the investigation of colour perception in ASD. Research is reviewed that identifies effects of colour on reading speed, visual discrimination and atypical behaviour in ASD. We also reviewed research that suggests that encoding of colour is atypical in those with ASD, and studies that provide evidence for reduced chromatic discrimination in those with the disorder. The theoretical and practical implications of investigations of colour perception in ASD are highlighted. Avenues for further research are suggested that could clarify how those with ASD process and experience the world of colour.
