Experiment 3: Sleep protects verbal memory from non-associative interference. (A) Experimental design is nearly identical to Experiment 1 with the following exception: Just before testing, participants acquired a second list (C-D) that had no words in common with the first (A-B). (B) Percent test recall of A-B stimulus pairs for Sleep and Wake groups of participants is shown. Inset shows percent test recall of C-D stimulus pairs for the same 2 groups. †0.05 < P < 0.10; ns, not significant. The bars represent one standard error of the mean (SEM).
