Statistical estimation task: saccadic performance as a function of the width of distractors. Primary saccades only, excluding the infrequent revisits. (a) Hit rate: the ratio of the number of target circles fixated divided by the number of total circles fixated. (b) Saccade rate: number of circles fixated/s. (c) Number of target circles fixated/s. Three different lines represent three temporal epochs (blue: 1-s trial; black: first second of the 2-s trial; red: last second of the 2-s trial). Bars show ± SE; otherwise, SEs are smaller than the plotting symbols.
