antisaccadetaken

Antisaccadetaken, commonly referred to as the antisaccade task or antisaccade paradigm, is a cognitive oculomotor task used to study inhibitory control and voluntary gaze. In a typical trial, a participant fixates a central point; a peripheral cue appears, and the instruction is to suppress looking toward the cue and instead generate a saccade to the mirror location on the opposite side. The task assesses the ability to inhibit a reflexive response and to execute a voluntary eye movement in a non-preferred direction.

Procedures usually include alternating pro-saccade and anti-saccade conditions. In pro-saccade trials, participants look toward the cue; in anti-saccade trials they look away from the cue. Key metrics are antisaccade error rate (occurrence of looking at the cue), antisaccade latency (time from cue onset to the initiation of the antisaccade), and error-correction rate. Antisaccade latencies are typically longer than pro-saccades due to the additional processing required to inhibit the reflex and plan a mirror movement.

Neural basis involves widespread oculomotor and cognitive control networks. The dorsolateral prefrontal cortex (DLPFC), frontal eye fields (FEF), supplementary eye fields (SEF), and posterior parietal cortex contribute to voluntary control and inhibition, while the superior colliculus and basal ganglia (including the subthalamic nucleus) participate in saccade generation and suppression.

Clinical and research relevance includes assessment of executive function and inhibitory control. Antisaccade performance is often altered in schizophrenia and other psychiatric or neurodevelopmental conditions, and it is used to study aging, neurodegenerative diseases, and the development of oculomotor control across the lifespan. Variants include memory-guided and delay versions, as well as gap versus overlap cue designs.
