Abstract

This study examines whether ADHD traits are associated with distorted perceptions of cognitive performance. 200 adults will complete online tasks and, after each, will rank their performance relative to a hypothetical comparison group. It is hypothesized that estimated performance will be higher than actual performance at higher levels of ADHD.
