Saccade launch and landing point distributions. Gaussian kernel density estimates and histograms of the time headways of saccade launch points (cyan) and landing points (purple; black dots in Fig. 2). The data were pooled across all participants. The panels show data for the three different speeds in Experiment 1. Both the time headways and the amount of variation appear to drop as the speed increases (see Table 1 for between-subjects deviations and Table 2 for within-subjects deviations. See Supplementary Fig. S1 for analysis of the increase in speed and the distance of saccade landing points).
