Figure 9.

Comparison of the motion sensitivity of perceptual and oculomotor data for At (A–D) and Av (E–H). A, E, The motion (coherence and time) dependence of evoked-saccade deviation (|γ₁| in Eq. 6b) plotted versus the motion dependence of behavior (a in Eq. 2). B, F, The motion dependence of voluntary-saccade latency plotted versus the motion dependence of behavior. C, G, The motion dependence of voluntary-saccade mistargeting plotted versus the motion dependence of behavior. In A–C and E–G, points represent data from all individual sessions. D, H, Discrimination thresholds measured from behavior (black) and inferred from evoked-saccade deviation (red) and voluntary-saccade latency (green) and mistargeting (blue) data. Thresholds were inferred using the best-fitting, absolute value of γ₁ as a parameter in the decision model. Points represent data from individual sessions. Lines are 41-session running means. Points for each data type were rescaled to have equal overall median values; therefore, only the relative trends across sessions are meaningful.
