Fig 2. Anti-saccade performance of CUD/AUD subjects and control subjects on the cocaine eye-tracking task.
Panels A and B show mean total anti-saccade errors and attentional bias scores (± SEM), respectively. The attentional bias score was calculated as anti-saccade errors on cocaine-stimulus trials / total anti-saccade errors on all trials, providing an indicator of attentional bias towards cocaine cues.
