Covariograms of percept switches and large (>1°) retinal image shifts.

<p>Shifts were produced by saccades (red) or stimulus jumps (blue). A: Switches from the non-preferred to the preferred eye. B: Switches from the preferred to the non-preferred eye. Top panels show the results from individual subjects. Bottom panels plot the mean across all four subjects. Shaded areas denote ± 1 SEM. Gray horizontal lines represent zero deviation from the baseline shift predictor (c.f., <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0061702#s2" target="_blank">Methods</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0061702#pone-0061702-g002" target="_blank">Figure 2</a>). The vertical gray bar is an estimate (mean±SD) of the moment that the actual percept switch occurred relative to the moment of the button press (i.e., the reaction time obtained from the stimulus flip condition in control experiments). Red and blue horizontal lines above the graphs from individual subjects indicate a significant peak in that time window for saccade or stimulus jump frequency, respectively; similarly, red and blue lines underneath the graphs indicate significant troughs.
