The paper updates the Enhanced Perceptual Functioning (EPF) model, originally proposed by Mottron and Burack in 2001, to better understand the perceptual characteristics of autistic individuals. The EPF model highlights differences in visual and auditory perception, enhanced low-level discrimination, use of posterior networks in complex tasks, enhanced perception of static stimuli, diminished perception of complex movements, and a differential relationship between perception and general intelligence. These differences may explain the choice of special abilities in savant autistics and the variability in presentations within Pervasive Developmental Disorders (PDD). The model suggests that overfunctioning of brain regions involved in primary perceptual functions may contribute to the autistic perceptual endophenotype. The authors review the original EPF model, assess relevant research from the past five years, and present an updated EPF model based on eight principles of autistic perception. They also discuss the mechanisms underlying EPF, including neuronal growth, cortical rededication, and compensatory adaptations, and highlight the importance of local and global processing in understanding autistic perception.The paper updates the Enhanced Perceptual Functioning (EPF) model, originally proposed by Mottron and Burack in 2001, to better understand the perceptual characteristics of autistic individuals.
