Decline in episodic memory is one of the most prominent cognitive deficits seen in late adulthood. It is therefore surprising that few studies have examined how the related capacity for episodic foresight might also be affected in this age group. Preliminary evidence suggests that older adults show deficits in generating phenomenological characteristics of future events, but the critical question of whether such deficits extend to generating and executing appropriate future intentions remains to be addressed. Here, we present 2 studies. In Study 1, we report the results of our pilot testing, which was used to develop and validate stimuli for the first measure of this construct that is appropriate for use in adult populations. In Study 2, we administer this measure to 40 older and 40 younger adults. The results indicate that, relative to their younger counterparts, older adults are less likely to spontaneously acquire items that would later allow a problem to be solved, and are also less likely to subsequently use these items to solve the problems. These data provide important initial evidence that the capacity to apply episodic foresight in a functionally adaptive way is impaired in late adulthood. The results also provide important validation data for a novel measure of episodic foresight that has potential application to many other groups, including clinical groups known to have difficulties anticipating and planning for the future.

People with schizophrenia have known difficulties with episodic foresight, and it now appears that those difficulties extend to the performance of foresightful preparatory behaviours. Because preparatory behaviours are central to routine and adaptive planning, difficulties with episodic foresight may contribute to or be a result of some of the functional difficulties experienced by people with schizophrenia. Further research is needed to determine whether interventions might be developed for people with reduced episodic foresight. Interventions may include the use of remedial tools that support and encourage the performance of foresightful behaviour, or cognitive training programs that actively improve the ability and propensity to exercise foresight independently.

These data provide important evidence suggesting that the functional aspect of episodic foresight is disrupted in long-term opiate users. While these deficits appear to have some links to impaired executive control, additional work is needed to gain a more complete understanding of the underlying cognitive and neural mechanisms involved. This, in turn, will have important implications for tailoring interventions with opiate users to maximise the likelihood of successful independent functioning.

Objective: Stroke is often associated with increased difficulty engaging in specific future-directed thoughts and behaviors, such as generating phenomenological characteristics of future events (a component of episodic foresight) and executing directed preparatory behaviors (a component of prospective memory). The objective of this study was to clarify whether this group also exhibits increased difficulties using episodic foresight to appropriately guide future-directed behaviors. Method: Stroke patients (n = 26) and demographically matched healthy controls (n = 26) were administered a behavioral measure that met strict criteria for assessing episodic foresight. In keeping with our focus on the functional application of foresight, this measure required participants to identify a problem, self-generate a resolution, and execute the appropriate future-directed intention. Results: Relative to controls, individuals who had suffered a stroke were less likely to acquire items that would later allow a problem to be solved and were also less likely to subsequently use these items to solve the problems. There were no group or task differences between left- and right-hemisphere-stroke subgroups. There were also no significant associations between our measure of episodic foresight with other cognitive measures or a measure of daily function. Conclusions: These data indicate that the capacity to apply episodic foresight in an adaptive way can be disrupted after stroke. Future work is now needed to more fully delineate the implications of difficulties engaging episodic foresight in everyday life as well as how these difficulties might be remediated.
