Given sufficient differences between direct and averted gaze and a long duration of exposure to the stimulus, individuals with ASD can make accurate judgments of eye contact. For example, high-functioning adults with ASD are as accurate as typical adults in discriminating between direct gaze and gaze averted 30 to the left or right. However, both children and adults with ASD are less accurate than controls in discriminating small differences between direct and averted gaze. Even when differences between direct and averted gaze are large, high-functioning adults with ASD are less accurate and slower than controls when the duration of exposure is short. These results suggest that the ability to discriminate between direct and averted gaze is impaired in individuals with ASD compared to that in typical individuals.
