Visual acuity is no different in those with ASC

Our paper on visual acuity in autism has been accepted for publication in Vision Research (T Tavassoli, K Latham, M Bach, SC Dakin, S Baron-Cohen. Psychophysical Measures of Visual Acuity in Autism Spectrum Conditions. Vision Research, in press). In this paper we show that visual acuity (or the ability to resolve or recognise small high contrast objects such as letters) is not more acute in those with autism, as had been suggested in previous work (Ashwin et al., Biol Psych, 2009), but nor is it worse. Hopefully this will settle this issue! People with autism may well perceive things differently visually, but the evidence is that this is not down to differences in visual input or early visual processing.
