Losing the light at the end of the tunnel: Depression, future thinking, and hope

Is the capacity to experience hope central to our ability to entertain desirable future possibilities in thought? The ability to project oneself forward in time, or to entertain vivid positive episodic future thoughts, is impaired in patients with clinical depression. In this article, I consider the causal relation between, on the one hand, the loss of the affective experience of hope in depressed patients, and on the other hand, the reduced ability to generate and entertain positive episodic future thinking. I suggest that findings in the philosophy of emotion may shed light on this causal relation.

The effects of left dorsolateral prefrontal transcranial direct current stimulation on episodic future thinking following acute psychosocial stress

ABSTRACT Introduction Research on stress-related disorders and brain imaging suggests that (acute) stress might impact the capacity to mentally simulate specific episodic future events (EFT) through the effects of cortisol on brain regions supporting this cognitive function, such as the prefrontal cortices. This study aims to examine the mechanisms underlying this link, using transcranial Direct Current Stimulation (tDCS) over the left dorsolateral prefrontal cortex. Methods 60 healthy participants were subjected to the Montreal Imaging Stress Task (MIST), followed by either active or sham tDCS. After stimulation, the EFT task was administered. Salivary cortisol was measured throughout the protocol. Results Higher cortisol AUCi values were linked to less specific episodic future thoughts. Moreover, active tDCS enhanced EFT specificity irrespective of cortisol, especially in high trait ruminators. We did not observe an effect from active tDCS on cortisol AUCi, and equally there was no interaction effect between cortisol AUCi and stimulation condition predictive for EFT specificity. Conclusion Although we did not find evidence for the effects of tDCS on the HPA-system, our data reveal a crucial link between two critical predictors of mental health for the first time, and provide a solution to help rehabilitate EFT deficits.

Exploring the impacts of implicit context association and arithmetic booster in impulsivity reduction.

People have a higher preference for immediate over delayed rewards, and it is suggested that such an impulsive tendency is governed by one’s ability to simulate future rewards. Consistent with this view, recent studies have shown that enforcing individuals to focus on episodic future thoughts reduces their impulsivity. Inspired by these reports, we hypothesized that administration of a simple cognitive task linked to future thinking might effectively modulate individuals’ delay discounting. Specifically, we used one associative memory task targeting intervention of context information, and one working memory task targeting enhancement of individual’s ability to construct a coherent future event. To measure whether each type of cognitive task reduces individuals’ impulsivity, a classic intertemporal choice task was used to quantify individuals’ baseline and post-intervention impulsivity. Across two experiments and data from 216 healthy young adult participants, we observed that the impacts of intervention tasks were inconsistent. Still, we observed a significant task repetition effect such that the participants showed more patient choices in the second impulsivity assessment. In conclusion, there was no clear evidence supporting that our suggested intervention tasks reduce individuals’ impulsivity, and that the current results call attention to the importance of taking into account task repetition effects in studying the impacts of cognitive training and intervention.

Discrete Emotions Caused by Episodic Future Thinking: A Systematic Review With Narrative Synthesis

Engaging in episodic future thinking, where a person imagines a specific, personal future, influences decisions partly through evoking affective experiences. While there is a growing literature on how future thinking influences affect, few studies have assessed this effect on discrete emotions. In this systematic review, we examined studies assessing the effects of episodic future thinking on discrete emotions. The aim was to provide an overview of which emotions have been studied, the evidence for an effect of future thinking on emotions, and the characteristics of emotional, episodic future thoughts. We identified 12 experimental studies (N = 2825) and synthesized these narratively. Findings suggest that episodic future thinking has some influence on several different emotions, including happiness, anxiety, and sadness. While the effects for most emotions were inconsistent, consistent effects were found for enjoyment and compassion. Imagining positive, personal future events can evoke enjoyment. Similarly, imagining instances of helping others in the future can elicit compassion. We suggest possible explanations for why future thinking only consistently influences some discrete emotions, emphasizing the cognitive appraisals and behavioral functions associated with different discrete emotions. We provide suggestions for empirically assessing effects of episodic future thinking on discrete emotions in future research.

Afterlife future thinking: imagining oneself beyond death.

Studies on episodic future thinking (the capacity to simulate possible experiences in one's personal future) have ignored future thinking that extends beyond death. We here examined personal afterlife projections in comparison with autobiographical memories and future projections in Thai (Study 1) and American (Study 2) samples. Participants reported all three types of events and rated their characteristics. In both studies, the characteristics of afterlife events were rated lower than those of memories and future events. Participants who believed in the afterlife generally rated afterlife events higher than non-believers and those who were uncertain, although this effect was most pronounced in Study 2. The content of afterlife events followed religious beliefs in the afterlife, and the majority of afterlife events were expected to take place immediately after death. The findings show that afterlife thoughts demonstrate characteristics that are comparable to memories and episodic future thoughts, and are shaped by religious beliefs.

Mental time travel into the episodic future, episodic past, and episodic counterfactual past in everyday life

AbstractTo date, studies exploring the relationship of counterfactual thoughts with episodic memories and episodic future thoughts have focused mainly on voluntary mental time travel. We explore mental time travel in everyday life and find that episodic counterfactual thinking occurs to a much lesser extent than thinking about the past or the future (12%, 22%, and 54%, respectively), is used mainly for mood regulation purposes, and the temporal distribution decreases as a function of time. We observe similarities in phenomenological detail: memories and counterfactual thoughts sharing similar ratings of sensory detail, memories and future thoughts sharing similar ratings of positivity, and counterfactual and future thoughts sharing similar ratings of mental time travel. We discuss the implications of episodic counterfactual thinking in everyday life.

Health Anxiety

Abstract. Health anxiety, characterized by excessive concern about one’s health, is a serious and costly public health problem. The disorder might become chronic if left untreated. Unfortunately many patients do not receive timely or proper treatment due to sparse treatment resources. Also, existing treatment programs, though effective for many, do not work for all. This paper discusses the conceptualization of health anxiety and future directions based on novel research findings. These include: (i) the content and characteristics of autobiographical memories and episodic future thoughts in severe health anxiety, (ii) related concepts such as cyberchondria with excessive Internet browsing on health issues and health anxiety by proxy, where parents display and might confer health anxiety towards their children, (iii) an epidemiological perspective on the association between health anxiety and subclinical psychotic experiences in preadolescence. Exploring these new dimensions could have important implications for the further development of preventive strategies and effective treatment.

Autobiographical Memory and Episodic Future Thinking in Severe Health Anxiety: A Comparison with Obsessive–Compulsive Disorder

Severe health anxiety is characterized by intrusive worries about harboring a serious illness. In the present study, 32 patients with severe health anxiety, 32 control participants and a clinical control group of 33 patients with obsessive–compulsive disorder (OCD) reported unprompted and anxiety-related autobiographical memories and episodic future thoughts. Compared to control participants, the patient groups displayed similar patterns in the characteristics of the reported events and regarding the maladaptive cognitive and behavioral strategies used, when the events came to mind. Patients with severe health anxiety reported more events related to their own illness or death than either of the other groups, and exploratory analyses suggested that they were more inclined than OCD patients to check their own bodies when anxiety-related events came to mind. Autobiographical memories and episodic future thoughts have not previously been examined in patients with severe health anxiety, but could play an important role in this disorder.

Psychometric Evaluation of an Episodic Future Thinking Variant of the Autobiographical Memory Test – Episodic Future Thinking-Test (EFT-T)

Abstract. Future-oriented variants of the Autobiographical Memory Test (AMT) are often used to assess the generation of specific episodic future thoughts, however, as yet the underlying factor structure of items in this modified test has not been examined. Therefore, over two studies we examined the factor structure and validity of an episodic future thinking variant of the Autobiographical Memory Test (Episodic Future Thinking-Test; EFT-T). In Study 1, exploratory factor analysis ( N = 466) showed a one-factor structure underlying responses to positive, negative, and concrete noun cue words on the EFT-T. In Study 2, confirmatory factor analysis with a different sample ( N = 304) and using different cue words showed a good fit for a single-factor structure. In both studies, good convergent validity was found with scores on the EFT-T correlating with autobiographical memory specificity scores, with support for divergent factors also. Mixed support was found for associations with measures of mental imagery, and the implications for measurement are discussed. These studies provide the first evidence that the EFT-T unidimensionally assesses specificity in episodic future thinking across two cue word sets.

Autobiographical memory and episodic future thinking in severe health anxiety: A comparison with obsessive-compulsive disorder

Severe health anxiety is characterized by intrusive worries about harboring a serious illness. In the present study, 32 patients with severe health anxiety, 32 control participants and a clinical control group of 33 patients with obsessive–compulsive disorder (OCD) reported unprompted and anxiety-related autobiographical memories and episodic future thoughts. Compared to control participants, the patient groups displayed similar patterns in the characteristics of the reported events and regarding the maladaptive cognitive and behavioral strategies used, when the events came to mind. Patients with severe health anxiety reported more events related to their own illness or death than either of the other groups, and exploratory analyses suggested that they were more inclined than OCD patients to check their own bodies when anxiety-related events came to mind. Autobiographical memories and episodic future thoughts have not previously been examined in patients with severe health anxiety, but could play an important role in this disorder.

Spontaneous future cognitions: an integrative review.

Spontaneous future cognitions refer to mental representations about the future that enter consciousness with no immediately preceding attempt of bringing them to mind. They are studied under different terms in several areas of psychology, but with little interdisciplinary exchange of findings and theoretical developments. Different conceptions of spontaneous future cognition derive from separate literatures and are rarely considered together, leaving their potential conceptual overlaps as well as their unique features unclarified. In this article, I review research on spontaneous future cognitions in relation to mind wandering, involuntary episodic future thoughts, and intrusive future imagery in cravings and clinical disorders. I conclude that more research is needed to clarify the potential functions served by spontaneous future cognitions in everyday life, under which conditions they may become dysfunctional, how they are triggered by situational cues, and how their content may be constrained by motivational factors and beliefs. The burgeoning field of spontaneous future cognitions forms a promising novel approach to the cognitive and motivational regulation of behavior in everyday life.

People infuse their passwords with autobiographical information

ABSTRACTPasswords might unlock more than our computer accounts. A New York Times Magazine described anecdotes of people who infused their passwords with autobiographical information [Urbina, I. (2014, November 20). The Secret Life of Passwords. New York Times. Retrieved from https://www.nytimes.com/2014/11/19/magazine/the-secret-life-of-passwords.html]. We suspected people infused their passwords with autobiographical information so they could privately remember that information. Across two studies we took a systematic approach to address the extent to which people infused passwords with autobiographical information and the functions that information served. We also examined the self-reported consequences of people infusing their passwords with autobiographical information. Across both studies, 41.6–71.1% of people infused their passwords with autobiographical memories; in Study 2, 9.3% of people infused their passwords with episodic future thoughts. People who infused their password with autobiographical information reported that information served identity, social, and directive functions, and they created their password to remember that information. These studies show that people do not simply use passwords to unlock their computer accounts. Some people might use passwords as mementos to cue autobiographical information.

Envisioning the times of future events: The role of personal goals.

Episodic future thinking refers to the human capacity to imagine or simulate events that might occur in one's personal future. Previous studies have shown that personal goals guide the construction and organization of episodic future thoughts, and here we sought to investigate the role of personal goals in the process of locating imagined events in time. Using a think-aloud protocol, we found that dates were directly accessed more frequently for goal-related than goal-unrelated future events, and the goal-relevance of events was a significant predictor of direct access to temporal information on a trial-by-trial basis. Furthermore, when an event was not directly dated, references to anticipated lifetime periods were more frequently used as a strategy to determine when a goal-related event might occur. Together, these findings shed new light on the mechanisms by which personal goals contribute to the location of imagined events in future times.

Imagining possible selves across time: Characteristics of self-images and episodic thoughts

Thinking about our possible selves can entail thinking about self-related imagined future events. When remembering and imagining, individuals can use both 1st person (field) and 3rd person (observer) perspectives. There is currently a paucity of research examining the visual perspectives of episodic future thoughts that represent possible selves. We hypothesised that temporally distant self-images would elicit more observer perspectives in episodic thoughts than temporally near self-images and current self-images. Utilising a repeated measures design, sixty-eight undergraduate students completed IAM, I Will Be near and I Will Be far conditions (Rathbone, Conway, & Moulin, 2011) to generate self-images and their related episodic thoughts. It was found that episodic qualities were reliably affected by different self-images. Specifically, observer perspective predilections increased with future temporal distance. Findings are discussed in relation to self-continuity with recommended practical applications of visual perspective utilisation for wellbeing.

Prevalence and determinants of direct and generative modes of production of episodic future thoughts in the word cueing paradigm.

Recent research suggests that episodic future thoughts can be formed through the same dual mechanisms, direct and generative, as autobiographical memories. However, the prevalence and determinants of the direct production of future event representations remain unclear. Here, we addressed this issue by collecting self-reports of production modes, response times (RTs), and verbal protocols for the production past and future events in the word cueing paradigm. Across three experiments, we found that both past and future events were frequently reported to come directly to mind in response to the cue, and RTs confirmed that events were produced faster for direct than for generative responses. When looking at the determinants of direct responses, we found that most past and future events that were directly produced had already been thought of on a previous occasion, and the frequency of previous thoughts predicted the occurrence of direct access. The direct production of autobiographical thoughts was also more frequent for past and future events that were judged important and emotionally intense. Collectively, these findings provide novel evidence that the direct production of episodic future thoughts is frequent in the word cueing paradigm and often involves the activation of personally significant "memories of the future."

Amnesia and future thinking: Exploring the role of memory in the quantity and quality of episodic future thoughts.

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 impairments are characterized by a paucity of memories from Recent Life. In comparison with controls, two features of his future thoughts are apparent: Reduced episodic future thinking and outdated content of his episodic future thoughts. This article suggests neuropsychologists should look beyond popular conceptualizations of the past-future relation in amnesia via focussing on reduced future thinking. Investigating both the quantity and quality of future thoughts produced by amnesic patients may lead to developments in understanding the complex nature of future thinking disorders resulting from memory impairments. We highlight the clinical importance of examining the content of future thoughts in amnesic patients, rather than only its quantitative reduction. We propose an explanation of how quantitative and qualitative aspects of future thinking could be affected by amnesia. This could provide a useful approach to understand clinical cases of impaired prospection. Systematic group investigations are required to fully examine our hypothesis. Although the current study utilized typical future thinking measures, these may be limited and we highlight the need to develop clinically relevant measures of prospection.

Predicting the phenomenology of episodic future thoughts

Recent findings suggest that multiple event properties contribute to shape the phenomenology of episodic future thoughts, but the specific role of each property is not yet fully understood. This study shows that different phenomenological features are predicted by distinct event properties. The vividness of an episodic future thought largely depends on the familiarity of its constitutive elements (i.e., the envisioned location, persons and objects), while the visual perspective adopted is instead related to the temporal distance of the imagined event. Cognitive feelings such as the sense of pre-experiencing the future depend on sensory-perceptual qualities, and are further modulated by the personal importance attributed to the event. These findings suggest that the essence of episodic future thought-the sensation of mentally visiting one's personal future-lies, in part, in the relevance of imagined events with respect to personal goals.

What differentiates episodic future thinking from complex scene imagery?

We investigated the contributions of familiarity of setting, self-relevance and self-projection in time to episodic future thinking. The role of familiarity of setting was assessed, in Experiment 1, by comparing episodic future thoughts to autobiographical future events supposed to occur in unfamiliar settings. The role of self-relevance was assessed, in Experiment 2, by comparing episodic future thoughts to future events involving familiar others. The role of self-projection in time was assessed, in both Experiments, by comparing episodic future thoughts to autobiographical events that were not temporal in nature. Results indicated that episodic future thoughts were more clearly represented than autobiographical future events occurring in unfamiliar setting and future events involving familiar others. Our results also revealed that episodic future thoughts were indistinguishable from autobiographical atemporal events with respect to both subjective and objective detail ratings. These results suggest that future and atemporal events are mentally represented in a similar way.

Tracking the construction of episodic future thoughts.

The ability to mentally simulate possible futures (episodic future thinking) is of fundamental importance for various aspects of human cognition and behavior, but precisely how humans construct mental representations of future events is still essentially unknown. We suggest that episodic future thoughts consist of transitory patterns of activation over knowledge structures at different levels of specificity, with general knowledge about the personal future (i.e., personal semantic information and anticipated general events) providing a context or frame for retrieving, integrating, and interpreting episodic details. In line with this hypothesis, Study 1 showed that the construction of episodic future thoughts is frequently a protracted generative process in which general personal knowledge is accessed before episodic details. We then explored in more detail the nature of this general personal knowledge and tested the hypothesis that it is mainly organized in terms of personal goals. Study 2 showed that cuing participants with knowledge about personal goals increased the ease of future event production during a fluency task. Study 3 further demonstrated that cuing participants with their personal goals facilitated access to episodic details during the imagination of future events. Taken together, these findings indicate that general personal knowledge and, in particular, knowledge about personal goals plays an important role in the construction of episodic future thoughts.
