Figure 5. Differential impact of REM sleep on emotional reactivity.

Figure 5

Difference in mean ratings between the pre-sleep and post-sleep test sessions across 4 emotion categories (fear, sad, anger, and happy) for (a) the Nap group overall performance, (b) only for those in the Nap group who obtained REM sleep, and (c) only for those in the Nap group who did not obtain REM sleep. Within-group comparisons (symbol above individual bars) reflect paired t-test significance (relative to null) at *<0.05 and **<0.01. Error bars represent s.e.m. Modified from (Gujar et al 2010).
