Fig 10. The effects of reward outcome on RT on the subsequent trial.

(A) The bar plot shows the difference in median RT after correct and incorrect trials in Experiment 1, and the gray circles show the difference in median RT for individual subjects. The solid gray line shows the average difference over all schedules, and a gray asterisk next to it indicates that this average was significantly different from 0 (two-sided sign test, p < 0.05). A black asterisk indicates that the difference in RT for a given schedule was significantly different from 0 (two-sided sign test, p < 0.05), and outliers are indicated by circles with a red cross. (B, C) The same as in (A) but for Experiments 2 and 3, respectively.
