Intertemporal decision-making is important for both economy and physical health. Nevertheless, in daily life, individuals tend to prefer immediate and smaller rewards to delayed and larger rewards, which is known as delay discounting (DD). Episodic future thinking (EFT) has been proven to influence DD. However, there is still no inconsistent conclusion on the effect of negative EFT on DD. Considering the perceived controllability of negative EFT may address the issue (Controllability refers to the extent to which progress and result of an event could be controlled by ourselves). In the current study, we manipulated EFT conditions (baseline, neutral EFT, negative-controllable EFT and negative-uncontrollable EFT), delayed time (i.e. 1 week, 1 month, 3 months, 6 months, 1 year and 3 years) and reward magnitude (small, large). We mainly found that when experiencing negative-uncontrollable EFT compared to negative-controllable EFT in the delayed time of 6 months with large rewards, individuals chose more delayed rewards, suggesting that negative-uncontrollable EFT effectively reduced DD under conditions of both large-magnitude reward and longer delayed time. The current study provides new insight for healthy groups on optimising EFT. In that case, individuals are able to gain long-term benefits in financial management and healthcare.

Although people with heroin addiction demonstrate impairment in delay discounting, no studies have explored the effects of drug-related cues on this impairment in this population. The present study aimed to examine the effects of suprathreshold and subthreshold drug-related cues on the level of delay discounting in individuals with heroin addiction. Study 1 recruited 37 male with heroin addiction and 34 male healthy individuals to complete an adapted version of the delay-discounting task. Drug-related or neutral cues of 500ms were presented before cross-selection was performed. Study 2 recruited 35 men with heroin addiction and 33 male healthy individuals who completed an adapted version of the delayed discounting task. Drug or neutral cues were presented for 33 ms with the addition of masked stimuli. The area under the curve values in the supra- and subthreshold drug-related cue conditions were significantly smaller than those in the neutral cue conditions in the group of participants with heroin addiction, but no such differences were found in the control group. This suggests that the level of delay discounting in people with heroin addiction is influenced by supra- and subthreshold drug-related cues, resulting in higher subjective discounting of delayed rewards. This finding may have clinical significance in the prevention of and intervention for heroin addiction. [ABSTRACT FROM AUTHOR]

Accruing evidence has attested to the plasticity of people's metaphorical perspectives on the movement of events in time, which oscillate between the ego-moving perspective and the time-moving perspective contingent on, among others, perception of distance to the future by virtue of individual differences in lifestyle and personality. Building on and extending this avenue of inquiry, the current research investigated the relationship between life history strategy, another time-related construct, and the preferred perspective in the resolution of a temporally ambiguous question. Studies based on self-report (Study 1) and behavioral (Study 2) measures showed consistent results, such that individuals with a fast life history strategy and those who preferred the smaller-sooner reward tended to adopt the ego-moving perspective, whereas individuals with a slow life history strategy and those who preferred the larger-later reward tended to adopt the time-moving perspective. Examination of the priming effect of temporal perspectives on intertemporal decision-making revealed that differential perceptions of temporal distance underlay the strategy-time relationship (Study 3). Taken as a whole, the current findings suggested that individual differences in life history strategy may also influence people's preferred perspective in the interpretation of ambiguous language related to time.

Background and aims: The intertemporal and risk decision-making impairments are vital cognitive mechanisms in internet use disorder (IUD). However, the underlying neural mechanisms for these two decision-making dysfunctions in individuals with IUD remain unclear. Methods: This study employed Functional Near-Infrared Spectroscopy (fNIRS) to record changes in blood oxygen concentration in the prefrontal cortex of individuals with IUD during intertemporal and risk decision-making tasks. Results: The findings revealed that the intertemporal decision-making deficits in IUD group were primarily associated with reduced activation in the left dorsolateral prefrontal cortex (dlPFC) and orbitofrontal cortex (OFC) and FC from the left dlPFC to the right dlPFC. On the other hand, risk decision-making impairments were linked to decreased OFC activation and weakened functional connectivity from the left dlPFC to the right dlPFC and OFC. Discussions and Conslusions: These results suggested that while there were common neural mechanisms underlying intertemporal and risk decision-making impairments in individuals with IUD, specific neural foundations existed for each type of dysfunction.

Numerous studies have examined the neural substrates of intertemporal decision-making, but few have systematically investigated separate neural representations of the two attributes of future rewards (i.e., the amount of the reward and the delay time). More importantly, no study has used the novel analytical method of representational connectivity analysis (RCA) to map the two dimensions' functional brain networks at the level of multivariate neural representations. This study independently manipulated the amount and delay time of rewards during an intertemporal decision task. Both univariate and multivariate pattern analyses showed that brain activity in the dorsomedial prefrontal cortex (DMPFC) and lateral frontal pole cortex (LFPC) was modulated by the amount of rewards, whereas brain activity in the DMPFC and dorsolateral prefrontal cortex (DLPFC) was modulated by the length of delay. Moreover, representational similarity analysis (RSA) revealed that even for the regions of the DMPFC that overlapped between the two dimensions, they manifested distinct neural activity patterns. In terms of individual differences, those with large delay discounting rates (k) showed greater DMPFC and LFPC activity as the amount of rewards increased but showed lower DMPFC and DLPFC activity as the delay time increased. Lastly, RCA suggested that the topological metrics (i.e., global and local efficiency) of the functional connectome subserving the delay time dimension inversely predicted individual discounting rate. These findings provide novel insights into neural representations of the two attributes in intertemporal decisions, and offer a new approach to construct task-based functional brain networks whose topological properties are related to impulsivity.

Objectives: The aims to investigate the mediating effect of intertemporal decision- making on the association between personality traits and self-management among individuals with in Type 2 Diabetes (T2DM). Method: Patients with T2DM in the early stages of hospitalization at two tertiary hospitals in Shenyang and Jinzhou, Liaoning Province, May 2022 to January 2023. Questionnaires, including General Demographic, Self-Management, Big Five Personality, and Intertemporal Decision-Making, were administered. Pearson correlation analysis examined relationships between personality traits, intertemporal decision-making, and self-management. Hierarchical regression analysis identified self-management predictors. Mediation analysis used the PROCESS SPSS Macro version 3.3 model 4 to investigate intertemporal decision- making as mediator between personality traits and self-management. Results: Pearson correlation analysis revealed significant associations between self-management scores, personality traits, and intertemporal decision-making. Hierarchical regression revealed that Neuroticism and Conscientiousness accounted for 20.8% of the variance in self-management, while intertemporal decision-making explained 4.5% of the variance. Finally, using the Bootstrap method, the mediation analysis showed that intertemporal decision-making partially mediated the effect of personality traits on self-management. Conclusion: This study emphasizes the importance of intertemporal decision- making in improving self-management behaviors among patients with T2DM. Interventions targeted at modifying intertemporal decision-making preferences could be effective in enhancing self-management behaviors, leading to better health outcomes. [ABSTRACT FROM AUTHOR]

Although procrastination has been extensively studied, precrastination remains an unsolved puzzle. Precrastination is the tendency to start tasks as soon as possible, even at the cost of extra effort. Using the near bucket paradigm with 81 undergraduate students, this study examined the relationship between precrastination and time perspective, proactive personality, and subjects' differential performance in intertemporal decision-making. The results confirmed the cognitive-load-reduction (CLEAR) hypothesis. Precrastination was found to be positively predicted by the future time dimension of time perspective and negatively predicted by proactive personality. In addition, there is a significant positive correlation between precrastination and delay discounting of intertemporal decision-making, which exists only for the loss situation.

According to the positive time-discounting assumption of intertemporal decision-making, people prefer to undergo negative events in the future rather than in the present. However, negative discounting has been identified in the intertemporal choice and loss domains, which refers to people’s preference to experience negative events earlier rather than later. Studies have validated and supported the "anticipated dread" as an explanation for negative discounting. This study again explored the effect of anticipated dread on intertemporal choice using content analysis; that is, having participants identify anticipated dread among reasons for negative discounting. This study also validated the effect of anticipated dread on negative discounting by manipulating anticipated dread. This study adds empirical and direct evidence for the role of anticipated dread in negative discounting.

Sleep restriction affects people's decision-making behavior. Nap restriction is a vital subtopic within sleep restriction research. In this study, we used EEG to investigate the impact of nap sleep restriction on intertemporal decision-making (Study 1) and decision-making across risky outcomes (Study 2) from ERP and time-frequency perspectives. Study 1 found that habitual nappers restricting their naps felt more inclined to choose immediate, small rewards over delayed, large rewards in an intertemporal decision-making task. P200s, P300s, and LPP in our nap-restriction group were significantly higher than those in the normal nap group. Time-frequency results showed that the delta band (1 ~ 4 Hz) power of the restricted nap group was significantly higher than that of the normal nap group. In Study 2, the nap-restriction group was more likely to choose risky options. P200s, N2s, and P300s in the nap deprivation group were significantly higher than in the normal nap group. Time-frequency results also found that the beta band (11 ~ 15 Hz) power of the restricted nap group was significantly lower than that of the normal nap group. The habitual nappers became more impulsive after nap restriction and evinced altered perceptions of time. The time cost of the LL (larger-later) option was perceived to be too high when making intertemporal decisions, and their expectation of reward heightened when making risky decisions—believing that they had a higher probability of receiving a reward. This study provided electrophysiological evidence for the dynamic processing of intertemporal decision-making, risky decision-making, and the characteristics of nerve concussions for habitual nappers.

To investigate the mechanism of episodic foresight of different valences on intertemporal decision-making, this study examined the mediating role of future self-continuity in the influence of episodic foresight on intertemporal decision-making and the moderating role of perceived control in two experiments. The results found that (1) future self-continuity mediated the effect of episodic foresight on individuals' intertemporal decision-making; and (2) perceived control moderated the indirect effect of episodic foresight on intertemporal decision-making through future self-continuity. Under low perceived control, individuals with positive episodic foresight had stronger future self-continuity and preferred future options, while individuals with negative episodic foresight had lower future self-continuity. In contrast, under high perceived control, individuals with different episodic foresight potencies did not show significant differences in their future self-continuity levels, but all showed higher levels and tended to choose the delayed option when faced with an intertemporal choice. From the perspective of the self-cognition, this study provided new insights into the relationship between episodic foresight and intertemporal decision-making and the psychological mechanisms of intertemporal decision-making.

Substance use disorder (SUD) is characterized by continued drug use despite adverse consequences. Methcathinone is a new type of psychoactive substance that is associated with high excitement and impulsive behaviors. However, it is unclear if individuals with methcathinone use disorders (MCUD) are with impaired decision-making ability. We analyzed the task performance in 45 male MCUD subjects and 35 male matched healthy controls (HC) with intertemporal decision-making task. Constant sensitivity discounting model was used to estimate potential changes in both discounting rate and time sensitivity. The results showed that MCUD individuals exhibited a higher delay discounting rate (p = 0.003, Cohen's d = 0.683) and reduced sensitivity to time (p < 0.001, Cohen's d = 1.662). The delay discounting rate was correlated to the first age for drug use (r = − 0.41, p = 0.004), and the time sensitivity was negatively correlated with the duration of abstinence (r = − 0.31, p = 0.036). We conclude that MCUD individuals are with impaired decision-making ability and time perception disturbances. [ABSTRACT FROM AUTHOR]

Objective:To explore the relationship between the intertemporal decision-making andtime perspective in heroin abstainers.Methods:According to DSM-5,333 heroin abstainers in a compulsory detoxification center were selected and investigated with the Monetary Choice Questionnaire（MCQ） and Zimbardo Time Perspective Inventory（ZTPI）.The MCQ was used to evaluate the delayed discount rate（k value） of intertemporal decision-making.Results:The average k value of heroin abstainers was 0.38.In ZTPI,the score of past negative time perspective was the highest（3.46±0.60） and the score of the future time perspective was the lowest（3.15±0.48）.The scores of present fatalism,present optimism,past negative perspective and past positive perspective were positively correlated with k value（r=0.16,0.13,0.14,0.10,Ps <0.05）,while the scores of future time perspective were negatively correlated with k value（r=-0.29,P <0.01）.The regression results showed that the scores of hedonic time perspective were positively associated with k value（β=0.19）,and the scores of future time perspective were negatively associated with k value（β=-0.33）.Conclusion:The higher the score of current heroin abstainers’ optimism,the more they tend to choose the immediate option,and the higher the score of future time perspective,the more they tend to choose the delayed option.

Purpose: To study the variations of delay discounting rates as a function of fluency, contents, and functions of future thoughts in healthy subjects. Background: Delay discounting (DD) is a concept that can measure a frequent tendency toward smaller, yet immediate rewards, while a delayed reward is greater in value. DD describes people's choices in intertemporal decisions and is associated with self‐control. Future thinking (FT) and having a vivid imagination of the future can reduce individuals' DD rates. However, constructing a specific episodic future representation was merely studied in relation to DD. Although fluency and contents of future thoughts have been reported related to various disorders and behaviors, their association with DD has not been previously addressed. Methods: The present study applies a verbal fluency task named the personal future task (PFT), the functions of future thinking scale (FoFTS), and the 27‐item delay discounting questionnaire (DDQ) in order to assess fluency, contents, and functions of future thoughts, and delay discounting in healthy subjects (N = 114, Female = 64%, Male = 36%, Mage = 34.22, SDage = 7.15). Results: Findings indicate that fluency of future thoughts is associated with DD. Among the contents of FT categories, financial contents (future thoughts about money and real estate matters), and regarding functions of FT, engaging in FT for planning are related to DD. Due to the final model, the above‐mentioned correlated variables can be considered as significant predictors of intertemporal choices when controlling for education and gender (R2 = 0.4, Adjusted R2 = 0.33, F = 5.186, p‐value = 0.001). Conclusion: The frequency of future thoughts one can generate, specifically future thoughts about financial contents, is associated with less short‐sighted intertemporal decisions. The former relationship is enhanced for longer delays (e.g., 5–10 years). Besides, individuals who frequently engage in FT for planning (planning out sequences of actions) discount future rewards to a lesser extent. [ABSTRACT FROM AUTHOR]

The intertemporal stability of research and development (R&D) investment is a key issue in successfully promoting the continuation of innovation activities under high uncertainty in entrepreneurship. R&D smoothing helps firms to navigate the uncertainties of the external environment and maintain the stability of their investments in innovation. Chief executive officers (CEOs) are the most important decision-makers in firms’ strategic planning. However, overconfident CEOs may overlook the importance of their firms’ strategic actions on innovative activities. Drawing on upper echelons theory, this paper examines how CEO overconfidence affects firms’ R&D smoothing. Using a sample of firms listed in China’s Growth Enterprises Market between 2013 and 2020, this study finds that CEO overconfidence has a significant negative impact on R&D smoothing. Furthermore, our findings reveal that firms’ internal control quality and institutional investor monitoring can mitigate the negative association between CEO overconfidence and R&D smoothing. Our findings provide new insights into the micro-level theoretical explanations for R&D smoothing and offer practical implications for technology-based entrepreneurial firms. [ABSTRACT FROM AUTHOR]

Obesity and related diseases have become one of the leading causes of death worldwide, which has been linked to biopsychosocial effects such as type 2 diabetes, cardiovascular disease, various cancers, depression, and weight stigma. Episodic future thinking (EFT) has been found to support the development of changes in health behaviors. However, the effectiveness of EFT in enhancing weight loss behavior and health outcomes is not well supported. To establish implementation options for the EFT intervention, and critically synthesize the data that assesses the impact of EFT on weight loss behavior and health outcomes. Searches were performed across 5 Chinese and 9 English databases systematically from inception to March 2023. Randomized controlled trials, written in English or Chinese were included. Two independent reviewers evaluated all relevant studies, who also assessed the risk of bias, and extracted the data. Meta-analyses were conducted using Review Manager 5.4.1. The quantity of evidence's certainty was assessed using the Risk bias assessment tool RoB2 (revised version 2019). This study was registered in PROSPERO. A total of 1740 participants were included, and 18 studies were eligible for inclusion. Meta-analysis reported a statistically significant effect size favoring EFT on delay discounting (AUC) (MD = 0.1, 95 % CI: [0.02, 0.17], P = 0.01; I2 = 73 %), delay discounting (K) (MD = − 0.85, 95 % CI: [− 1.44, − 0.26], P = 0.005; I2 = 77 %), energy intake (MD = − 107.59, 95 % CI: [− 192.21, − 22.97], P = 0.01; I2 = 57 %), grocery purchased (SMD: − 0.91, 95 % CI:[− 1.48, − 0.34], P = 0.002; I2 = 63 %), and BMI (MD = − 2.73, 95 % CI: [− 5.13, − 0.32], P = 0.03; I2 = 0 %, two studies). EFT was found to have favorable effects on delay discounting, energy intake, grocery purchased, and BMI of individuals. The presence of high heterogeneity is evident in most of the outcomes. The modalities of EFT intervention are still in the exploratory phase, there is no consensus on the valence, context type, longest delay time, and practice strategy, and it needs to be further explored for different populations. It is anticipated that additional well-designed studies will continue developing high-quality evidence in this field. [ABSTRACT FROM AUTHOR]

Intertemporal decision-making refers to the process whereby an individual evaluates and selects among competing alternatives based on the cost and benefit over time. While most previous studies on temporal discounting focused their attention on the gain context, only a few explored the loss context. In the present study, both the event-related potentials (ERPs) and the graph theory analysis were employed to investigate the differences in intertemporal decision-making between the gain and loss frameworks. Our results suggested that participants preferred the short latency/small amount (SS) alternatives and exhibited a smaller discount rate in a loss context compared to a gain framework. Furthermore, our ERP data indicated that the P200 component could constitute a preliminary assessment of the decision-making, related to gain and loss. In contrast, the N2 component was associated with negative emotions and showed significantly bigger amplitudes in the loss context, when compared to the gain framework. Further analyses of brain networks suggested the loss decision-making brain network to have a larger small-worldness index given individuals' loss aversion. Taken together, intertemploral decision-making in a loss context was accompanied by a greater brain response due to the negative emotions linked to loss aversion.

The processes involved in value evaluation and self‐control are critical when making behavioral choices. However, the evidence linking these two types of processes to behavioral choices in intertemporal decision‐making remains elusive. As the ventromedial prefrontal cortex (vmPFC), striatum, and dorsolateral prefrontal cortex (dlPFC) have been associated with these two processes, we focused on these three regions. We employed functional magnetic resonance imaging during a delayed discounting task (DDT) using a relatively large sample size, three independent samples. We evaluated how much information about a specific choice could be decoded from local patterns in each brain area using multivoxel pattern analysis (MVPA). To investigate the relationship between the dlPFC and vmPFC/striatum regions, we performed a psychophysiological interaction (PPI) analysis. In Experiment I, we found that the vmPFC and dlPFC, but not the striatum, could determine choices in healthy participants. Furthermore, we found that the dlPFC showed significant functional connectivity with the vmPFC, but not the striatum, when making decisions. These results could be replicated in Experiment II with an independent sample of healthy participants. In Experiment III, the choice‐decoding accuracy in the vmPFC and dlPFC was lower in patients with addiction (smokers and participants with Internet gaming disorder) than in healthy participants, and decoding accuracy in the dlPFC was related to impulsivity in addicts. Taken together, our findings may provide neural evidence supporting the hypothesis that value evaluation and self‐control processes both guide the intertemporal choices, and might provide potential neural targets for the diagnosis and treatment of impulsivity‐related brain disorders.

Temporal factors have an important role in intertemporal decision-making. Temporal focus is the extent to which individuals characteristically direct their attention to the past, present, and/or future. Temporal focus can influence resource allocation. It was not known, however, whether temporal focus might affect intertemporal decision-making. The purpose of this study is to investigate how life history strategies and temporal focus together influence intertemporal decision-making. Study 1 used a questionnaire to preliminarily explore the relationship between temporal focus and intertemporal decision-making. Results showed that temporal focus was positively associated with individuals' intertemporal decision preferences, and the more individuals preferred future focus, the higher their rate of temporal discounting. Study 2 examined the joint effect of the temporal focus and life history strategy on intertemporal decision-making by manipulating the temporal focus of individuals with different life history strategies. The manipulation of temporal focus influenced intertemporal decision preferences of fast strategy individuals, that is, the short-term small reward in the future focus and the long-term large reward in the past focus, but has no effect on the intertemporal decision preference of slow strategy individuals. The entire study confirms life history theory and validates the role of perceptual time-based models in intertemporal decision-making. • Temporal focus can influence intertemporal decision-making. • Temporal focus influence fast-strategy for intertemporal decision-making. • Temporal focus does not influence fast-strategy for intertemporal decision-making. • Manipulating temporal focus can guide individuals to rational decision making.

Discount rates are often elicited using incentivized or hypothetical multiple price lists. We conduct two multiple price lists according to Coller and Williams (Experimental Economics2: 107–127, 1999) with varying ranges of larger–later payments. Participants carry out both tasks and are randomly assigned to a task order as well as to a payment or no-payment treatment. Our results indicate that the range of the first completed task anchors discount rate decisions. Participants who begin the task with the lower range of the larger–later payments stated lower discount rates than participants who start with the task containing a wider range. Paying monetary incentives does not influence the detected anchor effect. [ABSTRACT FROM PUBLISHER]

The relationship between intertemporal and risky decision-making has received considerable attention in decision research. Single-process theories suggest that choices involving delay and risk are simply two manifestations of the same psychological mechanism, which implies similar patterns of neural activation. Conversely, the dual-system theory suggests that delayed and risky choices are two contrasting types of processes, which implies distinct brain networks. How these two types of choices relate to each other remains unclear. The current study addressed this issue by performing a meta-analysis of 28 intertemporal decision-making studies (862 subjects) and 51 risky decision-making studies (1539 subjects). We found no common area activated in the conjunction analysis of the delayed and risky rewards. Based on the contrast analysis, delayed rewards were associated with stronger activation in the left dorsal insula, while risky rewards were associated with activation in the bilateral ventral striatum and the right anterior insula. The results align with the dual-system theory with separate neural networks for delayed and risky rewards. • Neural signatures of delayed and risky rewards are compared. • Delayed and risky rewards engaged distinct neural circuits. • Delay elicited more activation in left dorsal insula than risk. • Risk elicited more activation in VS and right anterior insula than delay. • The meta-analysis findings favor the dual-system theory.

The author derives a new concept of the model of the subject discounting of utility function or consumption on a theoretical basis. He surveys the formation and evolution of models for calculating the subjective discount factor (β) . This paper focuses on the exponential and hyperbolic discounting utility model, which is among the current mainstream for its simplicity. The author builds on these models, as well as alternative models generated by the critics of the two oldest models of discounting. The aim of this paper is to find a model that extends the generalized hyperbolic model parameters representing the effect of uncertainties of the environment in the intertemporal decision-making. The original generalised hyperbolic model was extended with the subjective probability of the negative environment with its negative effect on current consumption and the positive effect on future consumption of the agents or vice versa. The paper presents a link between the neoclassical and hedonic approach. The parameters introduced in the model are mainly of psychological nature (risk aversion, loss aversion, etc.). Using the final parametric model, we may, for instance, explain why the subjective discount factor (β) is increasing, i.e. leading to delaying (desired) consumption, although the subjective discount rate (ρ) (patience of consumption) is positive and also increasing.
