The present study analyzed individual differences in the use of organizing strategies and considered their relation to retention performance on lowand high-meaningful paired associates. It also assessed the influence of instructions on the performance of 297 college students using different organizing strategies. The main conclusions reached were: (a) the type of organizing strategy used in memorizing strongly influences recall on tasks involving short-term memory; (b) relatively speaking, subjects are fairly consistent in their use of a particular memory strategy, although they have greater difficulty using high-level organizing strategies on some low-meaningful tasks; and (c) orienting instructions exert a potent influence on retention performance.Until recent years, experimental psychologists have been critical of the strategies that their subjects invariably use in memorizing. Whenever possible, they designed their experiments to eliminate what they regarded as idiosyncratic techniques (Woodworth & Schlosberg, 1954, p. 708). In the sixties, however, many researchers turned to a consideration of human learning as it actually occurs. This shift in approach has led to research on strategies, with interest focusing mainly on natural language mediators and their influence on short-and longterm retention. A major conclusion has been that natural language mediators enhance retention more than rote learning (e.g., Adams, Thorsheim, & Mclntyre, 1969; Groninger, 1966; Montague, Adams, & Kiess, 1966), although there has been some 1 This study derives from a doctoral dissertation submitted to the Department of Educational Psychology of New York University in partial fulfillment of the requirements for the Ph.D. degree.
