Episodic foresight and aging

Quarterly Journal of Experimental Psychology, 2016

Episodic future thinking (EFT), the ability to project into the future to “preexperience” an event, and prospective memory (PM), remembering to perform an intended action, are both examples of future-oriented cognition. Recently it has been suggested that EFT might contribute to PM performance but to date few studies have examined the relationship between these two capacities. The aim of the present study was to investigate the nature and specificity of this relationship, as well as whether it varies with age. Participants were 125 younger and 125 older adults who completed measures of EFT and PM. Significant, positive correlations between EFT and PM were identified in both age groups. Furthermore, EFT ability accounted for significant unique variance in the young adults, suggesting that it may make a specific contribution to PM function. Within the older adult group, EFT did not uniquely contribute to PM, possibly indicating a reduced capacity to utilize EFT, or the use of compensa...

Episodic Future Thinking (EFT) has been linked with our ability to remember past events. However, its specific neurocognitive subprocesses have remained elusive. In Study 1, a study of healthy older adults was conducted to investigate the candidate subprocesses of EFT. Participants completed a standard EFT cue word task, two memory measures (Verbal Paired Associates I, Source Memory) and two measures of executive function (Trail Making Test, Tower Test). In Study 2, healthy young adults also completed an EFT task and neuropsychological measures. The link between neurocognitive measures and five characteristics of EFT was investigated. Specifically, it was found that Source Memory and Trail Making Test performance predicted the episodic specificity of future events in older but not younger adults. Replicating previous findings, older adults produced future events with greater semantic but fewer episodic details when compared with young adults. These results extend the data and emphasise the importance of the multiple subprocesses underlying EFT.

Efficient intention formation might improve prospective memory by reducing the need for resource-demanding strategic processes during the delayed performance interval. The present study set out to test this assumption and provides the first empirical assessment of whether imagining a future action improves prospective memory performance equivalently at different stages of the adult lifespan. Thus, younger (n = 40) and older (n = 40) adults were asked to complete the Dresden Breakfast Task, which required them to prepare breakfast in accordance with a set of rules and time restrictions. All participants began by generating a plan for later enactment; however, after making this plan, half of the participants were required to imagine themselves completing the task in the future (future thinking condition), while the other half received standard instructions (control condition). As expected, overall younger adults outperformed older adults. Moreover, both older and younger adults benefi...

Episodic future thinking refers to mentally traveling forward in time to preexperience an event, and emerging research suggests that this is more difficult for older adults. The current study was designed to better understand the effect of aging on separate component processes of age differences in episodic future thinking. Young (n ϭ 24) and older (n ϭ 25) adults were asked to construct a) atemporal scenarios, b) future scenarios, and c) a narrative that involved navigation. Each of these conditions assesses the capacity to construct and describe a scene, but only the future scenario requires a subjective sense of self in time (autonoetic consciousness). The composite measure of performance showed that relative to young adults, older adults have substantially reduced capacity for all three types of construction, suggesting that age-related difficulty imagining future episodic events may reflect a more general cognitive decline with age. In addition, older adults were worse at imagining future experiences than atemporal experiences, indicating limited capacity for autonoetic consciousness. Further, this difference between imagining atemporal and future experiences was not as evident among younger adults. These deficits in episodic future thinking have implications for the daily lives of older adults in terms of anticipating and planning for the future.

Existing laboratory paradigms of prospective memory instruct subjects to remember to perform a single, isolated act at an appropriate point in the experiment. These paradigms do not completely capture many everyday complex prospective memory situations in which a series or set of delayed actions is planned to be executed in some subsequent period of time. Weadapted a laboratory paradigm within which to study these prospective memory processes, and we investigated age-related influences on these prospective memory processes. Age-related declines were found in the planning, initiation, and execution of the set of tasks. In contrast, there were no age differences in plan retention or in the fidelity with which the plan was performed.

To examine the impact of memory accessibility on episodic future thinking. Single-case study of neurological patient HCM and an age-matched comparison group of neurologically Healthy Controls. We administered a full battery of tests assessing general intelligence, memory, and executive functioning. To assess autobiographical memory, the Autobiographical Memory Interview (Kopelman, Wilson, & Baddeley, 1990. The Autobiographical Memory Interview. Bury St. Edmunds, UK: Thames Valley Test Company) was administered. The Past Episodic and Future Episodic sections of Dalla Barba's Confabulation Battery (Dalla Barba, 1993, Cogn. Neuropsychol., 1, 1) and a specifically tailored Mental Time Travel Questionnaire were administered to assess future thinking in HCM and age-matched controls. HCM presented with a deficit in forming new memories (anterograde amnesia) and recalling events from before the onset of neurological impairment (retrograde amnesia). HCM's autobiographical memory impa...

Retrieved intentions often cannot be performed immediately and must be maintained until there is an opportunity to perform them. In 3 experiments, on seeing a target event, younger and older participants were to withhold an action until they encountered the appropriate phase of the experiment. When initial retrieval was made facile by the use of a salient retrieval cue, the age-related decrements were often dramatic, even over unfilled delay intervals as brief as 10 s (Experiments 1 and 2). When initial retrieval was difficult, older adults showed no forgetting over the retention interval (Experiment 3). Several theoretical perspectives were offered as explanations for the age differences observed with salient retrieval cues, including those that focus on age differences in metamemory, the degree to which plans are reformulated, and the ability to nonstrategically maintain current concerns in working memory.
