Reliability of the key measures from the motion coherence (A), multiple-object tracking (B, C), useful visual working memory change detection (D), and useful field of view (E, F, G, H) tasks. Note. Red markers indicate mean group performance from sessions 1 and 2. Error bars show ± standard error of measurement (SEM). Black markers indicate individual participant scores for session 1 and session 2; where multiple participants have the same score, black markers overlap.
