(A) Example decision period trajectory of the left eye position overlaid with movements identified through velocity zero crossings. Color corresponds to movement cluster identity in (B ,C). Image is the last time point in the decision period. (B) Horizontal (x) and vertical (y) positions of eye across time from the trace in (A). Individual movements are plotted above as x/y traces, with dotted lines corresponding to the middle time point, and blue and red points indicating the start and end, respectively. Colors correspond to clusters in (C). (C) Top: example individual movements from 10 k-means clusters; magenta is the trajectory, blue and red are start and end points, respectively. Bottom: individual movement clusters for binocular (top row) and monocular (bottom row) conditions, with means plotted over 100 individual examples in gray. (D) Mean number of movements per trial for each cluster in binocular (blue) vs. monocular (magenta) conditions. (E) Mean amplitude of movement clusters for binocular (blue) and monocular (magenta) conditions. (F) Normalized movement frequency as a function of time before the jump for all clusters. (G) Mean trial duration (decision period only) for the two conditions. (H) Mean of the total distance traveled by the eye during the decision period for the two conditions. (I) Mean head pitch, measured as the angle between the eye and ear, across the decision period for the two conditions. (J) Relationship between the change in head pitch and change in cluster frequency between the binocular and monocular conditions. Dotted line is fit from linear regression.
