“…The present study could not confirm the eagle-eyed VA hypothesis of autism as postulated by Ashwin et al (2009a, b). VA in ASD was consistent with the one measured in TYP and SCH when using a short viewing distance, the default number of trials and no “post-hoc maximum likelihood analysis” in FrACT.…”

“…In their reply, Ashwin et al (2009b) explained their intent when making changes to the FrACT defaults and acknowledge that a chain of unrelated events may have affected the magnitude of the VA measures obtained, but not the existence of the difference between individuals with ASD and controls. They argue that both groups were tested under the same settings in randomized order and that the FrACT is obviously blind to diagnosis.…”

Autism spectrum disorders (ASD) have been associated with sensory hypersensitivity. A recent study reported visual acuity (VA) in ASD in the region reported for birds of prey. The validity of the results was subsequently doubted. This study examined VA in 34 individuals with ASD, 16 with schizophrenia (SCH), and 26 typically developing (TYP). Participants with ASD did not show higher VA than those with SCH and TYP. There were no substantial correlations of VA with clinical severity in ASD or SCH. This study could not confirm the eagle-eyed acuity hypothesis of ASD, or find evidence for a connection of VA and clinical phenotypes. Research needs to further address the origins and circumstances associated with altered sensory or perceptual processing in ASD.

Enhanced performance upon the Embedded Figures Test (EFT) in individuals with autism spectrum disorder (ASD) has informed psychological theories of the non-social aspects that characterise ASD. The Extreme Male Brain theory of autism proposes that enhanced visual acuity underpins greater attention to detail (assessed by the EFT) which is a prerequisite for Systemizing. To date, however, no study has empirically examined these relationships. 13 males with ASD and 13 male controls were assessed upon tasks argued to reflect these levels of processing. The ASD group were found to have significantly greater visual acuity, EFT performance and Systemizing ability than the control group. However, regression analysis revealed that the strongest relationship was between visual acuity and EFT performance.
