时间是影响决策偏好一致性的重要因素,时间框架与行为决策之间的相互关系是决策科学领域关沣的重要问题.本研究采用实验方法,运用跨时选择研究范式对延迟决策和提前决策进行对比研究.实验结果表明,时间框架对跨时选样产生显著影响;同一时间距离条件下,提前框架下的时间折扣低于延迟框架下的时间折扣,即存在时间维度的框架效应. 相似文献

调节焦点理论提出,自我调节过程中存在着提升焦点和预防焦点这两种不同的目标追求策略。基于以往研究,本研究提出,自我解释和时间距离会交互影响着人们的调节焦点。研究结果发现,自我解释能够显著地预测调节焦点;独立自我解释更可能激活个体的提升焦点倾向,而依赖自我解释更可能激活个体的预防焦点倾向。此外,近期时间距离启动条件下,独立和依赖自我解释使得个体的调节焦点的差异倾向性更为明显,但是对远期时间距离的知觉则使得依赖自我解释的个体更加偏离预防焦点倾向,趋向于提升性焦点,并与独立自我解释差异不大。 相似文献

理论上,人们对不同个体行为是否违背道德的判断是完全一致的。本研究提出,人们对社会距离线索的知觉会影响对道德行为的判断。研究设计了两个实验,分别从社会距离直接启动和社会距离线索启动的角度对这一假设进行了检验。结果发现,较近的社会距离启动及社会距离线索都能促使个体采取更温和的道德判断,功利主义的色彩比较浓厚,而较远的社会距离启动促使个体采用更加严格的道德判断,表现出道义论倾向。文章最后讨论了这一结果对未来研究的意义。 相似文献

采用图片描述范式探讨了不同年级印尼留学生汉语句子产生中的跨语言句法启动效应。结果发现,印尼语主动句启动条件下中年级印尼留学生没有产生跨语言句法启动,而高年级印尼留学生产生了跨语言句法启动;印尼语被动句启动条件下中、高年级印尼留学生均产生明显的跨语言句法启动。本研究结果初步表明,印尼留学生印尼语-汉语间跨语言句法启动与词序无关而与汉语水平有关。即使启动句为词序不同的印尼语被动句时,也能产生印尼语-汉语间跨语言句法启动。中年级印尼留学生句法表征中母语句法特征占优势,高年级印尼留学生句法表征中母语和汉语两种句法 相似文献

本文分别以90名和70名大学生为被试,通过问卷调查和实验任务的方式,探究童年环境、当前环境压力、时间感知和跨期选择四者之间的关系。结果表明:(1)童年环境影响时间感知,相比童年社会经济地位高的个体,童年社会经济地位低的个体更倾向于高估时距。(2)在正常环境下,个体时间感知完全中介作用于童年环境和跨期选择之间的关系,童年环境通过影响个体时间感知进而影响个体的跨期选择。(3)在当前环境压力下,时间感知并未起到中介作用。研究表明,时间感知在童年压力与在当前环境压力条件下,对跨期选择的影响作用不同。 相似文献

组织与个人面临的许多决策, 既无纯粹获益, 也无纯粹损失, 往往需要同时对未来不同时间点的损益加以权衡, 这类损益兼具的决策称为混合跨期决策。过往研究通常沿用纯粹获益或损失跨期决策的理论框架, 缺乏与混合跨期决策相匹配的理论建构和决策过程探索。基于此, 本研究从趋近-回避动机理论出发, 探索动机冲突影响混合跨期决策的过程机制。研究1拟探讨混合跨期决策中动机冲突特点, 及其与决策行为之间的关系。研究2则计划分别操纵影响动机冲突程度的内源性因素(得失金额的相对差异程度)和外源性因素(资源有限程度), 试图揭示动机冲突程度与混合跨期决策之间的因果链条。研究3拟采用鼠标追踪技术, 基于决策过程指标进一步探索动机冲突影响混合跨期决策的过程机制。我们预期该研究结果有利于从动机冲突视角揭示并建构混合跨期决策的作用机制, 同时也将为涉及混合跨期情境的企业管理和个体消费决策提供科学依据。 相似文献

Prior research has provided substantial insight into individuals’ intertemporal preferences (i.e., preferences about delayed rewards). In the present study, we instead investigated the preferences of small groups of individuals asked to express collective intertemporal decisions. The paradigm consisted of three phases. During the precollaboration and postcollaboration phases, participants completed an intertemporal decision task individually. During the collaboration phase, participants completed a similar task in small groups, reaching mutually-agreed-upon decisions. The results suggest that group preferences were systematically related to the mean of the group members’ precollaboration preferences. In addition, collaborative decision making altered the group members’ intertemporal preferences. Specifically, individuals’ postcollaboration preferences converged toward the preferences of their respective groups. Furthermore, we found that individuals’ postcollaboration preferences were independently related to both their precollaboration preferences and the preferences of the other group members, suggesting that individuals’ postcollaboration preferences represented a revision of their precollaboration preferences based on the preferences observed in other group members. In Experiment 2, we demonstrated that similar patterns of results were found whether participants were making matching judgments or binary choices. 相似文献

We infer the thoughts and feelings of others by taking their perspectives. Similar processes could be used to understand how we will be affected by future events, by allowing us to take the perspective of our future self. In this paper, we test this idea using a previously presented framework for guiding predictions. The framework proposes that a shared neural mechanism is involved in controlling egocentric bias, both while shifting our perspective away from self and towards others, and while shifting our perspective from immediate to future perspectives. To test this framework, 36 adults performed an intertemporal choice task. They were then scanned using 3T functional magnetic resonance imaging while completing a false-belief “localizer” task, which requires egocentric bias control. A positive correlation was observed between the right temporoparietal junction (rTPJ) response during the false-belief task, and preferences for delayed rewards in intertemporal choices. A subset of participants performed the intertemporal choice task again in the scanner, which revealed that the response of the same rTPJ cluster, individually localized during the false-belief task, was higher during delayed over immediate reward choices. In addition, functional connectivity between the rTPJ and ventromedial prefrontal cortex was found to differ between immediate and delayed choices. The current results indicate an overlap in processes of egocentric bias control and those that determine preferences in intertemporal choices, offering a social cognitive explanation for why rewards are devalued with delay in temporal discounting. 相似文献

跨期选择以往的研究集中于金钱数量结果。基于维度加工的模型,本文探究了在跨期选择中,人们面对质量差异的结果(如,今天的低配版手机还是六个月后的高配版手机)vs.相对应的金钱结果(如,今天的5000元还是六个月后的6000元)的选择偏好差异。3个实验结果表明:人们面对质量结果(相比于金钱结果)的跨期选择表现得更耐心,而这种现象是由于人们面对选择时在结果维度差异感知不同所致。与金钱结果跨期选择相同,质量结果跨期选择的心理加工过程同样遵循维度间差异比较。本研究为基于维度的跨期选择模型提供了新的证据。 相似文献

The effects of self–other decision-making on intertemporal choice have been revealed in many studies using a monetary outcome. However, the outcome of intertemporal choice is not restricted to money; time is also a scarce and nonrenewable resource outcome. Thus, we conducted a series of experiments to address the effects of self–other decision-making on time-based intertemporal choice, a type of intertemporal choice that uses time as an outcome. Over the course of three experiments, differences in self–other decision-making were evidenced. Participants who made decisions for others were more likely to prefer the smaller but sooner (SS) option over the larger but later (LL) option and considered the gain of the SS option to be significantly greater than that of the LL option. Participants who made decisions for themselves were likely to prefer the LL option over the SS option. However, they considered the gains of the LL and the SS option to be indifferent. Changing the role of decision-making could affect the ability of individuals to consider the future consequences of their decisions. The effects of self–other decision-making on time-based intertemporal choice could be explained by the accounts of economic reasoning and construal level theory. The findings indicated that the effects of self–other decision-making on time-based intertemporal choice, which could be generated simply by rewording questions, can help individuals make optimal long-term choices without the need for increased control. 相似文献

Previous studies using Western samples have found that introducing uncertainty to an intertemporal choice decreases the degree of discounting future rewards. The authors of this article examined the effect of risk on intertemporal choice using Chinese participants and found that respondents preferred the smaller but sooner (SS) outcome to the larger but later (LL) one in the presence of risk, which indicates that risk increases rather than decreases the degree of discounting future rewards. Thus, variations in response patterns between different cultural groups suggest that culture may play an important role in intertemporal choice and researchers should delve into this topic from an emic rather than an etic perspective. 相似文献
