Kindergarten, fourth-grade, and tenth-grade subjects were shown pictures representing combinations of high and low inter-item association and high and low category relatedness. Results support a hypothesis that young children cluster in recall as a function of associations while older individuals show organizational flexibility which serves to…

Reports two experiments showing a possible developmental shift from memory organization based on associative criteria to an organization based on categorical criteria. Children in first, fourth, and seventh grades were given a sort/recall task with items that could be organized into groups of categorical or associative pairs. (Author/CB)
