Abstract

We conducted a perceptual organization task requiring detection of horizontal vs. vertical organization of elements in a 20x20 array, with 100, 90, 80, or 70% coherence. Eye tracking and pupilometry were employed as biomarkers of performance. Percent organization was correlated with pupil dilation and amount of horizontal saccades by participants.
