How do we remember future plans? In this study, three experiments were conducted to examine this issue. Thirty to forty different undergraduate or graduate students participated as subjects in each experiment. In Experiment 1, subjects were asked to memorize plans for a day, assuming that they were of tomorrow in the ‘future’ condition and that they were of yesterday in the ‘past’ condition. The result showed that plans for the morning and the evening were recalled better than plans for the daytime (the U-shape effect), only in the future condition. In Experiment 2, plans were presented without time, so that subjects could not use any specific schema associated with time. In this condition, the U-shape effect disappeared. In Experiment 3, subjects were required to memorize plans for two days, tomorrow and the day after tomorrow. The result showed the U-shape effect for each day, not for two consecutive days. These results lead to the conclusion that some ‘temporal information’ about a day may affect the memory for future plans.
