Abstract
A correct use of the visual behavior (VB), and its integration with motor function, represents the earliest mean used by infants to explore and act on the social and non-social surrounding environment. The aim of this mini review is to present influential evidence of abnormalities in the VB domain in ASD individuals and to discuss the implication of these findings for early identification and intervention. We analyzed the possible anomalies in oculomotor abilities, visual attention, and visual-motor integration, as parts of a wider visual behavior defect, that could affect children with autism spectrum disorders (ASD) since the early stages of development. Conclusion: According to the literature, difficulties in these three areas have been often reported in children with ASD, and the visual-perception deficit could have cascading effects on learning processes and on social development. Despite this evidence of atypical VB in ASD, their investigation is not yet included into diagnostic processes, and they are not yet considered a specific treatment target.What is Known:•Atypical social use of visual behavior is one the first symptoms in children with autism spectrum disorders•Individuals with autism spectrum disorders often show unusual visual exploration of the surrounding environmentWhat is New:•It is possible to hypothesize that early visual behavior abnormalities may affect experiences that permit learning processes and social and communicative development in infants•An early assessment of visual behavior, as a core symptom of ASD, might improve the diagnostic processes and might help to developing more individualized treatments.
