From: The possibility to make choices modulates feature-based effects of reward
Behavioral results. (a) Mean reaction times in single-trials as a function of the proportion of choice-trials (0 to the left, 0.33 to the right) in the same block. The dashed line represents reaction times to targets in the color associated with low reward, the solid line reaction times to targets in the color associated with high reward. Error bars show standard errors of the means. (b) Mean reaction times in single-trials as a function of the preceding trial type (after a single trial with a high-reward target, after a single-trial with a low-reward target, and after a choice-trial), shown separately for targets associated with a low reward (striped bars) and for targets associated with a high reward (black bars). Error bars show standard errors of the means.
