The method of organization in free recall in the form of either clustering or subjective organization is explored in this study. This is just one of the possible forms of retrieval that may be employed. Other possibilities include serial recall, alphabetization, and imagery. To the extent that subjects employ such other strategies, correlations between organization indices and recall will be attenuated. This study explores this issue in two ways: first, about half the subjects (college students) were instructed to use a clustering strategy on a categorizable list. It was predicted that the correlation between clustering and recall would be higher for instructed than for non-instructed subjects. Secondly, subjects were asked to indicate the types of strategies they employed on a post learning questionnaire. It was predicted that subjects in the instructed group would report fewer strategies. The relationship of other individual difference variables to organization and recall has had little examination. Organization has been found to vary with internality-externality, intellectual ability, with chronological age, and with impulsivity/reflectivity in children. This study examined a number of such variables. (DEP)
