Effects of Time of Day and Information Importance on Adults’ Memory for a Short Story

An experiment is reported that tested subjects’ memory for information in a short story, either immediately after hearing the story or after a delay of one week. The story was presented, and the subjects tested, either in the morning or in the afternoon. The results showed that, although there was no overall effect of time of day of presentation on recall, relatively more important information from the story was recalled after a delay following presentation in the late afternoon, and more unimportant information following original presentation in the morning. The time of day of the delayed recall test did not have any effect on performance.
