Hypometria. Saccade amplitude (A) and probability (B) of observing a hypometric saccade, given that a saccade was generated, are plotted against saccade latency relative to stop cue onset. Data are from countermanding trials with (magenta circles) and without (blue squares) blinks. For both monkeys, hypometria was rare on trials without blinks, regardless of when the saccade occurred, but more prevalent after the onset of the stop cue in the blink trials.
