This study compared activity-based intentions with event- and time-based intentions. Forty-five participants completed a laboratory session that tested activity-, event-, and time-based prospective memory. Participants were then asked to keep a record of their planned academic and work-related activities for 1 week. Results revealed a main effect of context such that participants were better at performing intentions in the naturalistic setting than in the laboratory. A strong trend of intention type showed that event-based tasks were more likely to be performed than activity- and time-based tasks. An interaction of context and intention type suggested that participants were significantly better at performing time-based tasks in the naturalistic setting than in the lab. Nearly half of the participants reported using simple memory aids such as alarm clocks, parent or friend reminders, or other external cues. Strikingly, very few reported using electronic devices to aid their memory for future intentions.
