Effects of environmental context manipulated by the combination of place and task on free recall

Abstract

Three experiments, using a 2 (study context) × 2 (test context) between‐subjects design, were conducted to examine the effects of environmental context manipulated by the combination of two contextual elements, place and task, on free recall. Undergraduates individually studied nouns and received a free‐recall test, with a 10‐minute filled retention interval. The contexts were manipulated by the combination of task and place in Experiment 1, by place alone in Experiment 2, and by task alone in Experiment 3. For the manipulation of place and task, two perceptually distinctive places and two distinctive tasks (a calculation task and a fine‐motor task) were used. Tasks were imposed before and after studying target items and before a free‐recall test. Significant environmental‐context effects were yielded in Experiment 1, but not in the other experiments. The implications of the results are discussed.
