Reward expectation does not alter reaction times or movement times. A, Reaction time on each trial was defined as the time between the end of the sound stimulus and the exit from the center port. B, Average reaction times on each reward contingency for each mouse (11 mice, 6 sessions each mouse) on trials with leftward choices. C, Reaction time as in B for rightward choices. D, Movement time on each trial was defined as the time between the exit from the center port and the entry to a side port. E, Average movement times for each mouse for leftward choices. F, Average movement times for rightward choices. No statistical significance (p ≥ 0.05) is indicated by n.s.
