One important issue in cognitive aging research is the question of why memory declines in old age. Amongst the many memory sub-domains, prospective memory - memory for future intentions - has recently become of interest. While there is meta-analytic evidence of age-related decline in prospective memory performance, results on age-related differences vary considerably across studies. The “puzzle of inconsistent age-related declines in prospective memory” is a pressing issue in current gerontology and has not been resolved satisfactorily by previous research. Earlier studies have examined the role of cue focality in age-related differences in prospective memory performance. However, cue focality seems to explain only part of the age-related variance in prospective memory performance. Therefore, the present proposal systematically examines the additional influence of three alternative mechanisms possibly underlying adult age differences in prospective memory performance. Conceptually, predictions are derived from the multiprocess theory of prospective memory in which cue focality was initially introduced as only one of four prospective memory and ongoing task-related aspects potentially influencing prospective memory performance in general. Specifically, in three experiments on young and older adults using the same general empirical paradigm, besides the role of cue focality, the effects of ongoing task absorption, prospective memory cue distinctiveness, and cue-action associativity on age-related prospective memory performance will be investigated. Furthermore, besides specifying the relative importance of these different factors, for the first time possible interaction effects of the factors will be tested. By additionally examining ongoing task performance, it will be explored if the different factors affect prospective memory performance in the same or in different ways. Being the first study to systematically test the full set of predictors proposed by the multiprocess theory in young and older adults, the proposed research will not only enhance our understanding of mechanisms underlying age differences in the delayed realization of intentions but also substantially contribute to the conceptual knowledge in the field of cognitive aging.
