Abstract: Visual information is organised according to visual grouping principles. In visual grouping tasks individuals with ASD haveshown equivocal performance. We explored neural correlates of Gestalt grouping in individuals with and without ASD.Neuromagnetic activity of individuals with (15) and without (18) ASD was compared during a visual grouping task testinggrouping by proximity versus similarity. Individuals without ASD showed stronger evoked responses with earlier peaks inresponse to both grouping types indicating an earlier neuronal differentiation between grouping principles in individualswithout ASD. In contrast, individuals with ASD showed particularly prolonged processing of grouping by similarity suggestinga high demand of neural resources. The neuronal processing differences found could explain less efficient groupingperformance observed behaviourally in ASD.Keywords Autism spectrum disorder (ASD) · Gestalt perception · Grouping · Magnetoencephalography (MEG)
