Figure 2. Behavioral results of the two studies.
Effects of task are presented in the left column graphs while effects of incentives are on the right. Panel A. In Experiment 1, mean reaction time of correct trials was shorter for Reward than No- Reward trials, and for LC task relative to HC. In this version of the task, response accuracy was similar across conditions. Panel B. In Experiment 2, subjects’ responses were faster (top graph) and more accurate (bottom graph) for LC than HC, and for Reward or Penalty relative to No-Reward. No accuracy or reaction time difference was present between Reward and Penalty.
