Abstract: | ![]() The purpose of this study was to clarify the effect of the time of day on memory for the content of plans, and to examine the influence of knowledge of daily activities on it. Twenty‐four undergraduates participated as subjects in the experiment. Participants were told to memorize 24 plans of one day (e.g. ‘13:00’, ‘making a telephone call’), and were then asked to recall them in the test phase. Furthermore, we tried to explore their knowledge of everyday activities using a questionnaire. The result showed that plans of night, morning, and evening were recalled better than that of afternoon. This result was explained by the notion that knowledge of one's personal daily activities might affect memory of plans. Copyright © 2002 John Wiley & Sons, Ltd. |
