Figure 2.

Left panel: relative priming, calculated as primed minus nonprimed associational breadth scores, was elevated only for emotion cue words and only for the rapid eye movement (REM) sleep nap group. Right panel: detail of REM priming effect: post hoc tests show that only cue words with a positive emotional valence produced a priming effect at P < 0.05; two bars are shown for nonemotion cues due to slightly different size groups of participants receiving at least one negative (n = 19) and at least one positive (n = 12) cue word. P values are shown for pertinent within- and between-group contrasts.
