A Illustration of the Posner cued detection task. After 1000 ms of fixation, a cue (thickened placeholder) appeared for 100 ms at either side of the screen. On short SOA trials (short-SOA), the target (the letter X) occurred 150 ms after cue onset; on long SOA trials (long-SOA), the target appeared 600 ms after cue onset. The target appeared either on the same side of the screen as the cue (Congruent condition) or on the opposite site (Incongruent condition). Patients were required to press a central button with their right hand as soon as the target appeared while maintaining central fixation throughout the stimuli presentation. Catch trials (n = 24) had the same duration and cue presentation, but no target followed the cue. All trial types (n = 336) were equiprobable and randomly interleaved. Stimuli are not drawn to scale. B Patients’ performance is neurotypical. Two-way-ANOVA, *p = 0.047; **p = 0.008; ***p < 0.001. Error bars represent normalized SEM. n = 28 independent participants.
