antisaccade

A saccade that is directed toward a stimulus.

antisaccade

A voluntary eye movement made in the direction opposite to the side where a stimulus is presented. The subject is asked to fixate a small dot for some time. A stimulus is then presented to one side and the subject is asked to inhibit a reflex eye movement towards it but to make a saccade in the opposite direction. Analysis of the errors and/or latencies of the antisaccades indicate dysfunction in the frontal lobe, which controls the saccadic eye movements. See saccadic eye movement.

It was found that proactive interference affected low-span participants more than high-span (Kane & Engle, 2000), high-span participants were less vulnerable than low-span to salient distractors in a dichotic listening task (Conway, Cowan, & Bunting, 2001), high-span identified antisaccade targets faster than low-span in a antisaccade task (Kane, Bleckley, Conway, & Engle, 2001) and high-span were faster or less error prone than low-span in a Stroop task (Kane & Engle, 2003; Long & Prat, 2002).
