Prospective memory (PM) involves remembering intended actions in response to a target event or at a particular time. Both the PM theories and laboratory-based studies suggest that event-based tasks are less difficult to perform. The present study investigated whether the superior performance of event-based tasks generalizes to real-life intentions, and examined the relationships between the intention completion and various characteristics of daily living, for example, busyness, routine, affect, and stress. Every day, for 5 days, 129 participants listed their intentions for the following day and indicated whether intentions were time-based or event-based. As each day concluded, they evaluated the intention completion and characteristics of the passing day. The difference in performance between the two types of tasks was reversed using real-life intentions: Time-based intentions were performed better. Performance was also positively related to routine and positive affect and adversely related to stress. Mechanisms underlying PM performance in daily life are discussed.
