Advancement of myopic loss aversion theory has been hamstrung by conflicting results, methodological inconsistencies, and a piecemeal approach toward understanding the key factors influencing decision problem framing. A series of controlled experiments provides a more holistic view of the variables promoting myopia. Extending the information horizon promotes broad framing, which propels risk. Evaluation frequency and decision frequency interact regardless of information horizon, supporting the notion that restricting either mechanism alleviates myopia. When conducting evaluations infrequently, neither segregating nor aggregating retrospective returns significantly alters risk preferences. Moreover, students and real retirement plan participants exhibit comparable appetites for risk, implying that both groups frame decision problems similarly. Explanations for these findings and avenues for future research are discussed. 相似文献

Individuals who score high in intolerance of uncertainty (IU) display reduced threat extinction. Recently, it was shown that replacing threat associations with novel associations during extinction learning (i.e., presenting a novel tone 100% of the time) can promote threat extinction retention in individuals with high IU. This novelty facilitated extinction (NFE) effect could be driven by the tone's novelty or reliability. Here, we sought to address this question by adjusting the reliability of the novel tone (i.e., the reinforcement rate) during NFE. We measured skin conductance response during an associative learning task in which participants (n = 92) were assigned to one of three experimental groups: standard extinction, NFE 100% reinforcement, or NFE 50% reinforcement. For standard extinction, compared to NFE 100% and 50% reinforcement groups, we observed a trend for greater recovery of the conditioned response during extinction retention. Individuals with high IU relative to low IU in the standard extinction group demonstrated a larger recovery of the conditioned response during extinction retention. These findings tentatively suggest that NFE effects are driven by the novelty rather than the reliability of the new stimulus. The implications of these findings for translational and clinical research in anxiety disorder pathology are discussed. 相似文献

Recent research on verbal probability statements has revealed that some expressions (e.g., possible) are especially appropriate for describing outcomes in the high end of a distribution, whereas other expressions (e.g., certain) are more appropriate for describing low-end values. However, some dimensions appear to be reversible, with higher achievements sometimes associated with high and sometimes with low values, depending on frame. We report three experiments where this “reframing effect” is studied in communications of estimated performance time, both from a speaker's and from a listener's perspective. We hypothesize that statements describing tasks as “taking time” suggest a duration frame, and find accordingly that statements about how many hours that possibly will be spent on a task, or the time a task possibly takes, lead to high time estimates. Statements focusing on the actor's role suggest, in contrast, a speed frame, thus statements about what the actor can possibly do lead to low time estimates. Estimates of the time a task certainly takes or when it is certainly done follow the opposite pattern. The results are in line with approaches that see production and comprehension of language as a dynamical and context-driven process. 相似文献

The purpose of this study was to determine features of language use in the texts of poets who committed suicide and to identify psychological factors contributing to depression and suicide. Texts of suicidal and non-suicidal poets were analyzed via the Linguistic Inquiry and Word Count program. ANOVA and logistic regression analysis revealed predictors of suicide: higher percentage of words self-oriented, expressed negative emotions, ambiguity, exclusion attitude toward reality, and lower percentages of words related to others, world entitativity, and experiencing the world. The data support hypotheses that suicide is facilitated by weak social bonds, egocentrism, helplessness, and visions of an unordered, uncertain, and unsafe world. 相似文献

死亡凸显效应(mortality salience effect)是恐惧管理理论(terror management theory,TMT)中一个最重要的假设,它认为与死亡有关的想法会加强个体的世界观防御。不确定感管理模型(uncertainty management model)对死亡凸显效应做出了新的解释,指出以往的研究忽视了个体的不确定感对防御行为的影响。将这种理论和TMT进行了整合与探讨,可以认为死亡凸显对个体具有双重影响,个体在思考自己的死亡后会启动双重防御体系。未来的研究,应该关注各种防御方式互相影响的关系等。 相似文献

A conditioned taste aversion experiment tested context-switch effects on retrieval of conditioned stimulus (CS)–unconditioned stimulus (US) acquisition performance in rats. A context switch impaired performance when the target flavour was trained in a context where a different flavour underwent extinction. Conditioned taste aversion in the absence of previous extinction of the alternate flavour was not context dependent. It is suggested that the ambiguity in the meaning of the extinguished cue leads animals to pay attention to the context, so that the information learned in that context becomes context dependent. 相似文献

The influences of optimism and pessimism on ambiguity aversion were investigated in two tasks that manipulated the presence or absence of a potentially competitive experimenter. A total of 112 participants chose which option—ambiguous or known-risk—they preferred in the two slightly differing Ellsberg urns tasks. Optimism was measured using the Extended Life Orientation Test (ELOT). Highly optimistic people showed significantly less ambiguity aversion than less optimistic people when information was given that the number of balls was randomly determined. This pattern was present but less pronounced in the condition when the composition of the ambiguous urn could be interpreted as being influenced (rigged) by the experimenter. Pessimism was uninfluential. Perceptions of the situation, especially the degree of trust in the experimenter, were significantly influenced by the participants' optimism. People who do not have highly optimistic personalities tend to shy away from choosing ambiguous options. When ambiguity is clear, and trust issues are removed, people's optimistic outlook influences their degree of ambiguity aversion and thus their decisions. 相似文献
