RT switch costs and accuracy at the immediate and remote tests for the wake (green) and sleep (black) groups. (A) Action switch costs decreased across the wake retention interval but increased across the sleep interval. (B) Classification switch costs decreased across both wake and sleep retention intervals. (C) If classification task and action jointly switched, full switch costs slightly decreased across retention intervals and remained above zero in both wake and sleep groups. (D) Accuracy only decayed across the wake retention interval, leading to a higher accuracy for the sleep than the wake group at remote test. Means ± SEM are indicated (dot plots overlaid). Asterisks above individual conditions indicate significant differences from zero. (***) P < 0.001, (**) P < 0.01, (*) P < 0.05.
