Event-based prospective memory refers to remembering to perform an intended action in response to an anticipated event at some point in the future. In this article, the authors examined predictors of self-reported everyday memory failures using the Prospective and Retrospective Questionnaire (PRMQ; Smith, Della Sala, Logie, & Maylor, 2000) in a population-based sample of older adults (age range = 60-90 years; N = 250). The retrospective component refers to the content of the intention, in other words, remembering what has to be done. 1992; 4:257–267.

Marsh Received: 22 January 2007/Accepted: 10 December 2008 Springer-Verlag 2009 Abstract Implementation intentions are detailed and systematic plans that are developed during intention formation. 337 A key feature of many prospective memory tasks (in contrast to retrospective memory tasks) is the absence of an explicit reminder to recall the task when an opportunity to realize the intention occurs (e.g., Graf & Uttl, 2001). Greater effect of highly active antiretroviral therapy on survival in people aged > or =50 years compared with younger people in an urban observational cohort. The sheaf of papers could also remind us of a previously established intention to send out reprints to colleagues who have requested them. There are two main models of time perception, attention-based models, and memory-based models. This recall is triggered by either a stimulus or 'cue' or a time. For example, if you drank the last drop of milk this morning, no one would remind you on your way home from work to stop at the supermarket to buy some more.

Cues such as these engage retrospective memory processes for experiences that were recorded in the past.
