• Atkinson and Shiffrin ( 1968 ) argued that performance on any memory task reflects the combined influence of both the fixed structure of the memory system and control processes tailored to the specific task. We investigated the role of control processes in governing the temporal contiguity and semantic contiguity effects in free recall—tendencies to organize recall based on proximity in the study list and pre-existing semantic associations. Subjects studied lists that contained four “clusters”, each composed of four semantically associated words but presented in random order such that associates were not in adjacent serial positions. Subjects were given either standard free-recall instructions, instructions to focus on order-based associations (i.e., the original order of presentation), or meaning-based associations (i.e., pre-existing semantic relationships). Replicating previous work, lists with strong semantic relationships resulted in a reduced overall temporal contiguity effect when recalled under standard free-recall instructions. However, under meaning-based recall instructions, the temporal contiguity effect was nearly eliminated. Detailed analyses of within-cluster transitions and an order reconstruction task revealed that temporal information was encoded, but control processes prevented it from dominating memory search. These results point to a need for more empirical work exploring how control processes change recall dynamics and for more theoretical work modeling the computational basis of these processes.
