Item-based directed forgetting for categorized lists: Forgetting of words that were not presented.

The effect of item-based directed forgetting (DF) on recognition memory for categorized word lists was examined. For half of the categories, all studied exemplars were followed by a remember cue; for the other half of the categories, all studied exemplars were followed by a forget cue. In Experiment 1, a 2-alternative forced-choice recognition test showed decreased recognition for to-be-forgotten items.
