Abstract

In understanding the nature of visual cognition, it is important to determine how individual differences affect performance.
We have found relationships between symptoms of both ADHD and anorexia nervosa and performance on a simple visual search task at high set sizes. Both correlate with search accuracy such that greater symptoms predict worse performance. Critically, the type of errors made by each group reveals clear dissociations: ADHD-symptomatic individuals produced high miss rates while anorexia-symptomatic individuals produced high false alarm rates. We discuss how these differences in performance errors reveal how and why individual characteristics may influence visual performance.
