Abstract
Combined recognition and probe recall tasks with 3 retention intervals, 1, 4, and 10 sec., to study 144 undergraduates' memory for faces. In recognition, Ss decided whether a test face was the same as or different from a previously presented original. In recall, Ss indicated the size of a probed-for feature (e.g., eyes) of a previously presented original face. The number of features relevant to S's memory decision, r, was varied in both tasks and RT was the dependent measure. In recognition, same RT increased with r only at the longer retention intervals while different RT decreased with the number of features that differed between test and original at all retention intervals, suggesting that different retrieval processes underlied same and different judgments. Recall RT increased with r but was unaffected by retention interval, suggesting that retrieval in recall was from a verbal representation. (21 ref.)
