Prior work on retrieval-induced forgetting showed that retrieving a subset of formerly studied items can impair item recognition of related, nonretrieved material. Here it was investigated whether retrieval practice can also impair the items’ recognition as member of a studied category. Participants studied pre-experimentally unrelated words that were categorized by their font colors. After study, a subset of the words was retrieval practiced using a word stem completion task. Finally, an episodic category recognition test based on confidence ratings was applied. ROC analysis of the data demonstrated a reliable impairment in the nonretrieved items’ category recognition relative to control items. The result indicates that retrieval-induced forgetting is not restricted to item recognition but generalizes to category recognition tasks. Inhibitory as well as noninhibitory explanations of the finding are discussed.
