Recent studies have shown that imagining or simulating future events relies on many of the same cognitive and neural processes as remembering past events. According to the constructive episodic simulation hypothesis, such overlap indicates that both remembered past and imagined future events rely heavily on episodic memory: future simulations are built on retrieved details of specific past experiences that are recombined into novel events. An alternative possibility is that commonalities between remembering and imagining reflect the influence of more general, non-episodic factors such as narrative style or communicative goals that shape the expression of both memory and imagination. We consider recent studies that distinguish the contributions of episodic and non-episodic processes in remembering the past and imagining the future by using an episodic specificity induction—brief training in recollecting the details of a past experience—and also extend this approach to the domains of problem solving and creative thinking. We conclude by suggesting that the specificity induction may target a process of event or scene construction that contributes to episodic memory as well as to imagination, problem solving, and creative thinking.

Exact Repetition

Episodic memory is widely conceived as a fundamentally constructive, rather than reproductive, process that is prone to various kinds of errors and illusions. With a view towards examining the functions served by a constructive episodic memory system, we consider recent neuropsychological and neuroimaging studies indicating that some types of memory distortions reflect the operation of adaptive processes. An important function of a constructive episodic memory is to allow individuals to simulate or imagine future episodes, happenings and scenarios. Since the future is not an exact repetition of the past, simulation of future episodes requires a system that can draw on the past in a manner that flexibly extracts and recombines elements of previous experiences. Consistent with this constructive episodic simulation hypothesis, we consider cognitive, neuropsychological and neuroimaging evidence showing that there is considerable overlap in the psychological and neural processes involved in remembering the past and imagining the future.

Delayed Recognition

Human beings’ ability to envisage the future has been recently assumed to rely on the reconstructive nature of episodic memory ( Schacter & Addis, 2007 ). In the present research, young adults mentally reexperienced and preexperienced temporally close and distant autobiographical episodes, and rated their phenomenal characteristics as well as their novelty. Additionally, they performed a delayed recognition task including remember-know judgments on new, old-remember, and old-imagine words. Results showed that past and future temporally close episodes included more phenomenal details than distant episodes, in line with earlier studies. However, future events were occasionally rated as already occurred in the past. Furthermore, in the recognition task, participants falsely attributed old-imagine words to remembered episodes. While partially in line with previous results, these findings call for a more subtle analysis in order to discriminate representations of past episodes from true future events simulations.

Memory is typically thought of as enabling reminiscence about past experiences. However, memory also informs and guides processing of future experiences. These two functions of memory are often at odds: Remembering specific experiences from the past requires storing idiosyncratic properties that define particular moments in space and time, but by definition such properties will not be shared with similar situations in the future and thus may not be applicable to future situations. We discovered that, when faced with this conflict, the brain prioritizes prediction over encoding. Behavioral tests of recognition and source recall showed that items allowing for prediction of what will appear next based on learned regularities were less likely to be encoded into memory. Brain imaging revealed that the hippocampus was responsible for this interference between statistical learning and episodic memory. The more that the hippocampus predicted the category of an upcoming item, the worse the current item was encoded. This competition may serve an adaptive purpose, focusing encoding on experiences for which we do not yet have a predictive model.

Episodic memory (memories of the personal past) and prospecting the future (anticipating events) are often described as mental time travel (MTT). While most use this description metaphorically, we argue that episodic memory may allow for MTT in at least some robust sense. While episodic memory experiences may not allow us to literally travel through time, they do afford genuine awareness of past-perceived events. This is in contrast to an alternative view on which episodic memory experiences present past-perceived events as mere intentional contents. Hence, episodic memory is a way of coming into experiential contact with, or being again aware of, what happened in the past. We argue that episodic memory experiences depend on a causal-informational link with the past events being remembered, and that, assuming direct realism about episodic memory experiences, this link suffices for genuine awareness. Since there is no such link in future prospection, a similar argument cannot be used to show that it also affords genuine awareness of future events. Constructivist views of memory might challenge the idea of memory as genuine awareness of remembered events. We explain how our view is consistent with both constructivist and anti-causalist conceptions of memory. There is still room for an interpretation of episodic memory as enabling genuine awareness of past events, even if it involves reconstruction.

Pluralistic Contexts

Research on the strategic organization of time often assumes that collective efforts are motivated by and oriented toward achieving desirable, although not necessarily well-defined, future states. In situations surrounded by uncertainty where work has to proceed urgently to avoid an impending disaster, however, temporal work is guided by engaging with both desirable and undesirable future outcomes. Drawing on a real-time, in-depth study of the inception of the Restoration and Renewal program of the Palace of Westminster, we investigate how organizational actors develop a strategy for an uncertain and highly contested future while safeguarding ongoing operations in the present and preserving the heritage of the past. Anticipation of undesirable future events played a crucial role in mobilizing collective efforts to move forward. We develop a model of future desirability in temporal work to identify how actors construct, link, and navigate interpretations of desirable and undesirable futures in their attempts to create a viable path of action. By conceptualizing temporal work based on the phenomenological quality of the future, we advance understanding of the strategic organization of time in pluralistic contexts characterized by uncertainty and urgency.

To Come

Time, according to medieval theologians and philosophers, was experienced in radically different ways by God and by his creation. Indeed, the obligation to dwell in time, and therefore to have no sure knowledge of what was to come, was seen as one of the primary qualities which marked the post-lapsarian state. When Adam and Eve were cast out of the garden of delights, they entered a world afflicted with the changing of the seasons, in which they were obliged to work and consume themselves with the needs of the present day and the still unknown dangers of the next. Medieval concerns about the use and abuse of time were not merely confined to anxiety about the present, or awareness of seized or missed opportunities in the past. The future was equally worrying, in particular the extent to which this part of time was set aside for God alone, or whether it was permissible to seek to know the future, either through revelation and prophecy, or through science. In the fourteenth and fifteenth centuries, the scientific claims of astrology to provide a means to explain the outcome of past and future events, circumventing God’s distant authority, became more and more insistent. This paper begins by examining one skirmish in this larger battle over the control of the future.

AbstractThere are many questions we can ask about time, but perhaps the most fundamental is whether there are metaphysically interesting differences between past, present and future events. An eternalist believes in a block universe: past, present and future events are all on an equal footing. A gradualist believes in a growing block: he agrees with the eternalist about the past and the present but not about the future. A presentist believes that what is present has a special status. My first claim is that the familiar ways of articulating these views result in there being no substantive disagreement at all between the three parties. I then show that if we accept the controversial truthmaking principle, we can articulate a substantive disagreement. Finally, I apply this way of formulating the debate to related questions such as the open future and determinism, showing that these do not always line up in quite the way one would expect.

Humans frequently create mental models of the future, allowing outcomes to be inferred in advance of their occurrence. Recent evidence suggests that imagining positive future events reduces delay discounting (the devaluation of reward with time until its receipt), while imagining negative future events may increase it. Here, using a sample of 297 participants, we experimentally assess the effects of cued episodic simulation of positive and negative future scenarios on decision-making in the context of both delay discounting (monetary choice questionnaire) and risk-taking (balloon-analogue risk task). Participants discounted the future less when cued to imagine positive and negative future scenarios than they did when cued to engage in control neutral imagery. There were no effects of experimental condition on risk-taking. Thus, although these results replicate previous findings suggesting episodic future simulation can reduce delay discounting, they indicate that this effect is not dependent on the valence of the thoughts, and does not generalise to all other forms of “impulsive” decision-making. We discuss various interpretations of these results, and suggest avenues for further research on the role of prospection in decision-making.

Human beings regularly 'mentally travel' to past and future times in memory and imagination. In theory, whether an event is remembered or imagined (its ‘mnemicity’) underspecifies whether it is oriented towards the past or the future (its ‘temporality’). However, it remains unclear to what extent the temporal orientation of such episodic simulations is cognitively represented separately from their status as memories or imagination. To address this question, we investigated whether episodic simulations are more easily distinguishable in memory by virtue of their temporal orientation or their mnemicity. In three experiments (N = 360), participants were asked to generate and later recall events differing along the lines of temporal orientation (past/future) and mnemicity (remembered/imagined). Across all of our experiments, we consistently found that participants were more likely to confuse in recall event simulations that shared the same temporal orientation rather than the same mnemicity. These results show that the temporal orientation of episodic representations can be cognitively represented separately from their mnemicity and have implications for debates about the role of temporality in episodic simulation.
