Pre-saccadic attention for motion stimuli

A White, M Rolfs, M Carrasco

Saccade preparation results in selective performance benefits at target locations. These presaccadic attention shifts have been well documented for static stimuli. However, they have rarely been studied using dynamic stimuli, partly because saccadic suppression may affect motion processing around the time of saccades. Here, observers viewed an annular array of six motion patches (100% coherence, 6 possible directions). Following the appearance of a central movement cue, they saccaded to the patch to the left or to the right of fixation. During the latency of the saccade a speed change could occur in one of the six patches (the test patch), and we measured observers' sensitivity as a function of the distance between the test patch and the saccade target and the time relative to the saccade. Sensitivity was always highest at the two possible saccade targets, but within the last 100 ms before the saccade, the spatial profile of sensitivity shifted towards the current target. Motion appears to be a highly sensitive stimulus for the study of presaccadic attention and using it we will investigate the effect of relative motion direction at locations across the visual field.
