Figure 1. Experimental design and skill memory retention.

Figure 1

(a,b) Participants underwent 20 minutes of resting state fMRI before and after training on either the serial reaction time task (SRTT) or the force tracking task (FTT) while receiving reward, punishment, or control feedback. In the SRTT (c), participants responded to a cue appearing in one of four locations on a screen. In the FTT (d), participants modulated their grip force to track a moving target. In both tasks, the stimulus could follow either a random- or fixed-sequence, and skill memory was assessed by comparing performance during random- and fixed-sequence trials.
