Histograms of reaction time (RT) in the Pro Gap task before (top) and after (bottom) training in the Pro Gap task. Each of the 7 columns shows data for 1 of the 7 subjects (left to right, S1→S7). Number of correctly executed saccades is shown by open bars extending up. Number of saccades made in the wrong direction is shown by bars extending down. Anticipatory saccades (RT < 75 ms) are denoted by shaded bars. Vertical dashed line denotes 100 ms. Red lines indicate ex-Gaussian curve fits.
