Error repetition is a frequently observed phenomenon in a daily life when older adults use IT-based equipments; they repeat the same errorful operation at the same phase in the interaction just after they made the error. Previous researches identified this phenomena with an experimental task (KANJI selection task) both by younger and older adults, when they should maintain multiple goals; i.e., under divided attention, or in the task switching condition. Based on these results, error repetition phenomena appear to be related to cognitive control and Prefrontal function, and in this study an experiment was executed to see its relationship to time-of-day effects. Sixteen older and 33 younger adults participated experiments, half of them came in the morning, and the other in the afternoon. As previous experiments, both age groups showed error repetitions only with the condition in which the task was switched every 3 trials. Conditions of Time-of-day showed significant effects only with older participants, showing more repetitive errors at non-peak time. Relationship between aging, cognitive control as prefrontal functions and error-repetitions will be discussed.
