情节式未来思考中目标加工研究进展

情节式未来思考是个体将自我投射到未来以预先经历某事件的能力,个人目标加工在情节式未来思考中发挥着重要作用。目前对情节式未来思考中目标加工的行为学研究通常将其划分为目标过程模拟和目标结果模拟两种类型,以探究其对执行意图的影响为主;脑机制神经影像学研究则聚焦于默认网络的内侧前额叶和后扣带的重要作用,以及默认网络、额顶控制网络和奖赏区的协同作用。未来研究应进一步探讨情节式未来思考目标加工的形式、年龄差异及其与时间距离的关系。     

未来心理时间的新取向：集体未来思考

集体未来思考是指想象一个尚未发生的群体事件,其与集体记忆之间存在着复杂的相互作用。目前对集体未来思考的研究发现它的记忆基础更多为语义记忆。而有关集体未来思考的脑机制研究则相对较少,但在遗忘症患者中发现个体未来思考和集体未来思考是可分离的,并且非海马依赖的未来场景构建与集体未来思考可能存在重要联系。未来研究应该注重不同文化背景下的集体未来思考,探讨其产生条件及影响因素,并加强在正常人群中神经机制的研究,以更好地揭示集体未来思考的实质。     

未来取向研究概述

未来取向是指个人的思想和行为偏好未来的方向, 同时也是个体对于未来的思考和规划过程。未来取向心理结构的代表性观点有要素观、过程观和动机认知行为观。主要测量方式包括问卷法、投射法、圆环测验、讲故事技术和完成故事技术。个体的年龄、性别、人格和情绪等是未来取向的主要影响因素。未来取向在健康行为、物质滥用和学业成绩等方面起着积极作用。明确未来取向的功能机制、完善测量工具、采用精巧的实验设计并进一步探讨未来取向的脑机制是未来研究的方向。     

自我相关未来思考:两种基本类型及其主要心理成分比较

自我相关未来思考是个体产生自我相关未来想法的心理加工,它包括未来情景思考和未来个人语义思考两种基本类型。两类思考都需记忆、自我和主观时间三种主要心理成分参与,但参与的具体形式可能有所不同:未来情景思考可能主要依赖于情景记忆和语义记忆、情景自我知识和语义自我知识、经验时间;未来个人语义思考可能主要依赖于语义记忆、语义自我知识和知道时间。三种主要心理成分在两种思考类型中的作用可能是相同的,其中,记忆是原材料,自我起引导作用,主观时间是先决条件。将来可以参照思考未来公众抽象问题的研究进一步明确自我和记忆在未来个人语义思考中的作用,还可以通过探究不同心理成分内部及成分间的交互作用进而了解各成分在自我相关未来思考中的作用机制。     

未来定向和社会化

未来定向是指人们如何看待自己的未来,目标,希望以及期望,未来定向往往与青少年的积极的结果联系在一起。未来定向的研究领域涉及对个人有重要影响的生活领域,个人的学习,工作,娱乐,分析不同国家的文化背景,不同的社会地位的个体其未来定向存在的差异;讨论了不同性别,不同年龄的差异;探讨了个体的同一性发展,自我探索,自我承诺水平,自我效能感,内在控制感等与未来定向的关系。     

未来情景思考对目标达成的双刃作用及其机制

未来情景思考指个体想象并预先感受某个可能在未来发生的自我相关情景事件的心理加工,它对目标达成可产生双刃影响:一些思考方式会妨碍目标达成,如想象理想的结果或过程;而另一些思考方式则会促进目标达成,如过程模拟和想象较为消极的目标相关场景。对于未来情景思考是促进还是妨碍目标达成,动机水平的高低和执行意向的清晰程度可能是关键调节因素,相应的干预策略可通过增强这两者而将未来情景思考对目标达成的妨碍作用转化为促进作用。进一步的研究需系统探讨不同方式的未来情景思考影响目标达成的认知神经机制,并对目标特征和人格特点如何调节未来情景思考对目标达成的影响进行探讨。

本研究用修订的Fingman和Perlmuter的未来时间透视问卷、Lev-enson的控制观量表对167名大学生、46名进修教师和33名老年大学学员进行了测量。结果表明:①不同年龄被试者的未来时间透视具有相似的模式,即关注近的未来,并具有显着年龄差异和性别差异。②被试者关注未来时间的长度与控制观的内控水平呈正相关,与有势力的他人、机遇两水平呈负相关,但均未达到显着水平;关注未来时间的密度与控制观的三水平均呈微弱相关;但思考未来时间的清晰度与控制观的内控水平呈极显着的正相关,与有势力的他人、机遇两水平则呈显着负相关。     

创造性思维的脑机制

创造性思维是创造性的核心。近年来,脑电和脑成像技术的发展为研究创造性思维的神经基础提供了有力的技术支持,对创造性思维的脑机制研究取得了较大进展。创造性思维的脑机制研究主要包括顿悟的脑机制、发散性思维的脑机制、远距离联想的脑机制、言语创造性和图画创造性的对比的脑机制研究。研究结果显示创造性思维需要多个脑区的参与,因不同的认知任务其关键脑区而有所不同。对创造性思维的脑机制研究进行了总结,对这些研究可能存在创造性思维究竟应该定义为“领域一般的”还是“领域特殊的”的解释进行了讨论,并指出了研究中可能存在的基线任务设置问题和未来研究中需要在研究手段、研究设计、研究领域等方面加以改进的建议

Emotion matters: The influence of valence on episodic future thinking in young and older adults

In young adults, valence not only alters the degree to which future events are imagined in rich episodic detail, but also how memorable these events are later on. For older adults, how valence influences episodic detail generation while imagining future events, or recalling these details at another time, remains unclear. We investigated the effect of valence on the specificity and memorability of episodic future thinking (EFT) in young and older adults. Among young and older adults, negative EFT was accompanied by less episodic detail generation relative to positive and neutral EFT. A similar reduction in episodic specificity for negative EFT was found two days later when participants recalled their previously imagined events. Notably, while older adults generated less episodically specific future thoughts relative to young adults, age did not influence the effect of valence on episodic detail generation at imagination or recollection.     

Episodic future thinking: Linking neuropsychological performance with episodic detail in young and old adults

Episodic future thinking (EFT) has been linked with our ability to remember past events. However, its specific neurocognitive subprocesses have remained elusive. In Experiment 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 Experiment 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 than did young adults. These results extend the data and emphasize the importance of the multiple subprocesses underlying EFT.     

Does goal relevant episodic future thinking amplify the effect on delay discounting?

Delay discounting (DD) is the preference for smaller immediate rewards over larger delayed rewards. Research shows episodic future thinking (EFT), or mentally simulating future experiences, reframes the choice between small immediate and larger delayed rewards, and can reduce DD. Only general EFT has been studied, whereby people reframe decisions in terms of non-goal related future events. Since future thinking is often goal-oriented and leads to greater activation of brain regions involved in prospection, goal-oriented EFT may be associated with greater reductions in DD than general goal-unrelated EFT. The present study (n = 104, M_age = 22.25, SD = 3.42; 50% Female) used a between-subjects 2 × 2 factorial design with type of episodic thinking (Goal, General) and temporal perspective (Episodic future versus recent thinking; EFT vs ERT) as between factors. Results showed a significant reduction in DD for EFT groups (p < 0.001, Cohen’s d effect size = 0.89), and goal-EFT was more effective than general-EFT on reducing DD (p = 0.03, d = 0.64).     

Do process simulations during episodic future thinking enhance the reduction of delay discounting for middle income participants and those living in poverty?

Two studies examined whether episodic future thinking (EFT; pre‐experiencing future events) reduces discounting of future rewards (DD). No studies have investigated whether process simulations (i.e., simulating the process of executing a future event) amplify EFT's reduction of DD. Study 1 examined the effect of incorporating process simulations into EFT (N = 42, M_age = 43.27; 91% female, family income = $75,976) using a 2 × 2 factorial design with type of episodic thinking (process, nonprocess/general) and temporal perspective (EFT, episodic recent thinking) as between‐subjects factors. Study 2 replicated Study 1 in a sample of adults living in poverty (N = 36; M_age = 38.44, 88% female; family income = $25,625). The results of both studies showed EFT reduced DD, but process‐oriented EFT did not amplify the effect of EFT. Our findings suggest the key ingredient in EFT's effect on DD is self‐projection into the future. This was also the first study to show EFT improves DD in a sample living in poverty.     

Reconstructing the times of past and future personal events

Humans have the remarkable ability to mentally travel through past and future times. However, while memory for the times of past events has been much investigated, little is known about how imagined future events are temporally located. Using a think-aloud protocol, we found that the temporal location of past and future events is rarely directly accessed, but instead mostly relies on reconstructive and inferential strategies. References to lifetime periods and factual knowledge (about the self, others, and the world) were most frequently used to determine the temporal location of both past and future events. Event details (e.g., places, persons, or weather conditions) were also used, but mainly for past events. Finally, the results showed that events whose temporal location was directly accessed were judged more important for personal goals. Together, these findings shed new light on the mechanisms involved in locating personal events in past and future times.     

老年人对情绪性事件的情景模拟:回忆过去与想象未来

研究采用自传体访谈技术,首次考察了老年人在对情绪性事件进行回忆和想象中生成的内部细节和外部细节数量,及其对回忆和想象内容的主观评估。结果发现:(1)无论是回忆还是想象任务,老年人都比年轻人提供了更少的内部细节和略多的外部细节;(2)与年轻人相似,老年人在想象未来积极事件时产生了更多的内部细节,表现出对积极信息的加工偏好;(3)老年人比年轻人更倾向于认为想象的事件与过去发生的事件相似度高,表明该群体在想象过程中更多地依赖了过去的记忆。该结果揭示了老年人对情绪性事件的回忆和想象特点,说明在回忆和想象过程中出现的与年龄有关的缺陷同样会体现在情绪性事件中,这很好地支持了建构性情景模拟假说。     

Does episodic future thinking improve prospective remembering?

Extant findings suggest interesting avenues for the investigation of the potential relationship between EFT and PM. However, as they stand, they are inconclusive as to the causal role that EFT may play in aiding prospective remembering. In one Experiment, we showed that accuracy in a prospective memory (PM) task performed on the second day was significantly higher when participants, on the first day, had mentally simulated the sequence of events expected to occur on the second day, including the PM task, than when they had performed control tasks. These data extend previous findings on the functional benefit of future simulations in different domains by revealing a substantial facilitation effect of future-oriented thoughts on PM performance when the mentally simulated future task matched the actually executed task.     

Mental time travel into the past and the future in healthy aged adults: an fMRI study

Remembering the past and envisioning the future rely on episodic memory which enables mental time travel. Studies in young adults indicate that past and future thinking share common cognitive and neural underpinnings. No imaging data is yet available in healthy aged subjects. Using fMRI, we scanned older subjects while they remembered personal events (PP: last 12 months) or envisioned future plans (FP: next 12 months). Behaviorally, both time-periods were comparable in terms of visual search strategy, emotion, frequency of rehearsal and recency of the last evocation. However, PP were more episodic, engaged a higher state of autonoetic consciousness and mental visual images were clearer and more numerous than FP. Neuroimaging results revealed a common network of activation (posterior cingulate cortex, precuneus, prefrontal cortex, hippocampus) reflecting the use of similar cognitive processes. Furthermore, the episodic nature of PP depended on hippocampal and visuo-spatial activations (occipital and angular gyri), while, for FP, it depended on the inferior frontal and lateral temporal gyri, involved in semantic memory retrieval. The common neural network and behavior suggests that healthy aged subjects thought about their future prospects in the past. The contribution of retrospective thinking into the future that engages the same network as the one recruited when remembering the past is discussed. Within this network, differential recruitment of specific areas highlights the episodic distinction between past and future mental time travel.     

Characteristics of personally important episodic memories,counterfactual thoughts,and future projections across age and culture

We have limited knowledge as to whether the phenomenological differences between episodic memories, counterfactuals, and future projections show the same pattern across age groups and diverse samples. Here we compared the characteristics of these mental events, reported by younger and older participants in a Turkish (Study 1) and in an American sample (Study 2). In both studies, memories contained more sensory-perceptual-spatial details, were easier to bring to mind, and more specific. Future projections were the most positive, whereas counterfactuals were the least emotionally intense. In Study 1, older participants rated the events more positively and experienced them with more perceptual detail, whereas younger participants reported the future to be more voluntarily rehearsed, important, and central. These age differences did not replicate in Study 2. Overall, phenomenological differences between the events are robust and replicate across diverse samples. However, age differences are more sensitive to cultural or individual differences.
