Remembering an event typically takes less time than experiencing it, suggesting that episodic memory represents past experience in a temporally compressed way. Little is known, however, about how the continuous flow of real-life events is summarised in memory. Here we investigated the nature and determinants of temporal compression by directly comparing memory contents with the objective timing of events as measured by a wearable camera. We found that episodic memories consist of a succession of moments of prior experience that represent events with varying compression rates, such that the density of retrieved information is modulated by goal processing and perceptual changes. Furthermore, the results showed that temporal compression rates remain relatively stable over one week and increase after a one-month delay, particularly for goal-related events. These data shed new light on temporal compression in episodic memory and suggest that compression rates are adaptively modulated to maintain current goal-relevant information. 相似文献

The way people envision their future (self-prospection) plays a key role in the energization required to pursue desired goals. We proposed that energization is determined by time distance from the imagined future-self and the individual’s consideration of future consequences (CFC). We hypothesized that, when imagining their distant (vs. near) future-self, individuals higher on CFC (i.e., those who construe a stronger link between present and future selves), would report greater energization. Participants completed the CFC scale, imagined their distant or near future-self, and reported their energy level. Imagining distant (vs. near) future-self fostered energy among participants higher on CFC (Experiments 1–2), an effect mediated by vividness of self-representations (Experiment 2). Self-prospection has implications for current states, and specifically for felt energy. 相似文献

In two experiments, we demonstrate that despite indicating indifference when probed about risk or delay in isolation, when forced to explicitly trade‐off between the two, participants prefer delayed over risky rewards. This pattern of findings sets a boundary condition for any common utility‐based comparison process involving both risk and delay. Furthermore, this change from indifference‐in‐isolation to delay‐preference‐in‐a‐trade‐off strengthens as reward amount increases. Exploratory modeling results suggest that the shift in preference can be explained by allowing for different discount rates for delay‐only choices compared with when delay is in competition with risk. This explanation is better than one in which probability weighting is different between risk‐only choices and risks considered in the presence of a delay. Together, the empirical and modeling work lays a path for future investigations of why and when people's evaluation of the properties of risky and delayed choices vary as a function of the alternatives on offer.

Episodic memories are comprised of details of “where” and “when”; spatial and temporal relations, respectively. However, evidence from behavioural, neuropsychological, and neuroimaging studies has provided mixed interpretations about how memories for spatial and temporal relations are organised—they may be hierarchical, fully interactive, or independent. In the current study, we examined the interaction of memory for spatial and temporal relations. Using explicit reports and eye-tracking, we assessed younger and older adults’ memory for spatial and temporal relations of objects that were presented singly across time in unique spatial locations. Explicit change detection of spatial relations was affected by a change in temporal relations, but explicit change detection of temporal relations was not affected by a change in spatial relations. Younger and older adults showed eye movement evidence of incidental memory for temporal relations, but only younger adults showed eye movement evidence of incidental memory for spatial relations. Together, these findings point towards a hierarchical organisation of relational memory. The implications of these findings are discussed in the context of the neural mechanisms that may support such a hierarchical organisation of memory. 相似文献

This study explored how genotype information affects identification narratives of multiracial individuals. Twenty-one multiracial individuals completed individual interviews before and after receiving a DNA analysis to clarify their genetically based racial ancestry. Based on results, this article proposes patterns of articulating racial identity by multiracial individuals. Four patterns extend evolving research in multiracial identification, namely (1) the individual articulates a monoracial identity; (2) the individual articulates one identity, but this can shift in response to various conditions; (3) the individual articulates an extraracial identity, opting out of traditional categories applied to race; and (4) the person distinguishes traditional categories of race from culture and owns the two identities in different ways. Implications of these findings are discussed. First, adding new ancestry DNA information further muddles the neat categories of race, consistent with the view of race as socially constructed. Second, results emphasize the fluidity of identification for multiracial individuals. Third, DNA information challenges the neat percentages people tend to associate with their backgrounds. Particularly for younger multiracial individuals, there was less of a sense that race was a real thing and more that culture played a big part in how they saw themselves. 相似文献

People tend to think positively about their future selves. However, it remains unclear to what extent this tendency depends on the positivity of their current self-appraisal. To study this problem, we employed the assumptions of construal level theory, the concept of self-enhancement, and the assumptions of temporal self-appraisal theory, and we examined the role of global self-esteem in the relationship between temporal distance and future self-appraisals measured in absolute (Study 1), comparative temporal (Study 2), or comparative social (Study 3) ways. In all three studies, when assessed in terms of specific dimensions, future self-appraisals increased with temporal distance only in people with low self-esteem, but when assessed in terms of general dimensions, self-appraisals were higher in the distant compared to the near future irrespective of self-esteem level. 相似文献

This study develops a classification scheme that effectively separates delayed marriage and true childless couples from delayed empty nest couples, newlywed and traditional empty nest couples. Unlike extant traditional and ‘modernised’ life cycle models, this approach separates true childless and delayed marriage childless couple households from their traditional counterparts using the couples' length of marriage and wife's age. It also uses couples' ages at marriage to separate delayed from the traditional empty nest households. The findings clearly indicate that nontraditional ‘childless couples’ differ from their traditional counterparts in underlying values, sex role norms, and attitudes, as well as in food and beverage consumption and major durable acquisition patterns. Implications of this classification scheme for comprehensive life cycle models and future research and managerial applications of these findings are also discussed.

研究由两个实验组成,实验一采用纯粹的视听方式,以线段长度和声音频率为材料,对时序信息的加工方式(自动加工与控制加工)、编码特点(时序信息是何时编码的)以及通道效应进行了研究。实验二以汉字为材料重复实验一的过程;结果表明,时序信息的加工存在视听通道效应,其机制源于记忆,且与实验材料的加工深度以及加工方式有关;时序信息既包含有自动加工,又包含有控制加工。视觉刺激倾向于自动加工,而听觉则倾向于控制加工;时序信息是在项目学习时编码获得的,而不是在提取时建构的。 相似文献

采用实验室录像观察对中国儿童的行为抑制性的发展进行了追踪研究(2岁、4岁、7岁)。儿童2岁时,有124名儿童参加了实验室观察。儿童4岁时,由于搬迁、退出或失约,有103名儿童参加。儿童7岁时由于以上原因有100名儿童参加实验室观察。在2岁、4岁、7岁至少参加一次观察的儿童有113名,而在三个时间点都参加观察的儿童有89名。我们对儿童2~7岁行为抑制性整体发展的稳定性以及行为抑制性和非抑制性的发展趋向进行了分析。结果表明,中国儿童从2岁到7岁的行为抑制性的整体发展稳定性较低。从2岁到7岁,行为抑制性-非抑制倾向比较稳定的儿童共28人,占总人数的31.5%。而行为抑制性-非抑制性不稳定的儿童为61人,占总人数的68.5%。随着年龄增长,本研究中的儿童的行为抑制性-非抑制性倾向有向中间型趋中的趋势。从2岁到7岁,行为抑制性的发展变化没有显著性别差异 相似文献
