The effect of a classification, or encoding, task on intentional free recall was examined. Examination of the serial position curves for immediate and free recall shows clear effects assigned to long-term store. Consideration of effects regarding levels of processing gives a parallel account differing only in terminology and emphasis. (CHK)

Meyer found subjects were faster to determine if a stimulus word was a member of either of two prespecified categories if the categories were close in meaning. A reanalysis of the data favors instead a model emphasizing the role of decision-making processes in categorization and flexibility of task strategies. (CHK)

The "property-set model" is proposed for concept learning and subsequent recognition and classification of old and new exemplars. In an experimental evaluation of alternative models, the property-set model was the best predictor of both recognition and classification performance. (Author/RM)

In two experiments on free and cued recall, spacing between categorically related items, presentation rate and category size were varied and the effects on recall of items as a function of their serial order were studied. Results suggest subjects organize material during acquisition by retrieving and rehearsing previously studied items. (CHK)
