We examined whether 2 types of interpolated tasks (i.e., retrieval-practice via free recall or guessing a missing critical item) improved final recognition for related and unrelated word lists relative to restudying or completing a filler task. Both retrieval-practice and guessing tasks improved correct recognition relative to restudy and filler…

One of the foundational principles of human memory is that repetition (i.e., being presented with a stimulus multiple times) improves recall. In the current study a group of participants who studied a list of cue-target pairs twice recalled fewer targets than a group who studied the pairs only once, a negative repetition effect. Such a…

Testing typically enhances subsequent recall of tested material. In contrast, it has been proposed that consolidated memories can be destabilized when reactivated and then need to be reconsolidated in order to persist. Learning new material immediately after reactivation may disrupt reconsolidation. We investigated whether the well-known benefits…
