Oculomotor performance in the reactive and voluntary saccade conditions of Experiment I. Mean saccadic gain are shown in the pre- (white bars) and post-exposure phases (black bars). Upper row: reactive adaptation task of the Adapt-Left group (A) and Adapt-Right group (B); lower row: voluntary adaptation task of the Adapt-Left group (C) and the Adapt-Right group (D). Error bars indicate ±1 SEM. Asterisks denote significant differences between pre- and post- phases (Post hoc LSD test, p < 0.001).
