Item-specific representations were not modulated by pre-sleep testing.

To understand whether the pre-sleep testing influences memory reactivations, we performed a three-way repeated measures ANOVA, with pre-sleep testing (tested vs. untested), item-specificity (WI vs. BI), and post-sleep memory (remember vs. forget) as factors. No significant interaction effect was found in any individual time window (p > 0.081). Furthermore, a two-way repeated measures ANOVA with pre-sleep testing and item-specific representations as factors for post-sleep remembered items did not reveal any significant interaction effect (pcluster > 0.383).
