Abstract

The premotor theory of attention postulates that attention allocation and saccadic programming are strictly linked. We conducted an eye-tracking study to test this theory. Participants were presented with a centrally-located cue arrow and were instructed to make a saccade to the corresponding peripheral dot while attending to the center, in order to report a briefly-displayed target letter. Using two separate temporal cutoff criteria from the arrow onset, we found both significant increases in performance accuracy with practice and decreases in performance accuracy with longer cue delays, but with accuracies being above chance across conditions. These results suggest that attention allocation and saccadic programming may be governed by separate mechanisms.
