Autistic Adults Show Similar Performance and Sensitivity to Social Cues on a Visual Perspective Taking Task as Non-autistic Adults.

Autistic and non-autistic adults completed a visual perspective taking (VPT) task, reporting an object's location from an actor's perspective, or their own. On half the trials the actor looked at and reached for the object, and on half did not. Accuracy and reaction time were measured. In Experiment 1, both groups (N = 34, mean age = 24 years) responded slower when reporting the actor's perspective, with no group differences in this effect. Experiment 2 included "other" VPT trials only. Both groups (N = 30, mean age = 25 years) showed sensitivity to the actor's behaviour, more accurately reporting his perspective when he acted upon the object. No group differences were observed. In contrast to developmental studies, these experiments suggest similar VPT abilities in autistic and non-autistic adults.
