Loss aversion is an economic assumption about utility—people value giving up a good more than they value getting it. It also has hedonic meaning—the pain of a loss is greater in magnitude than the pleasure of a comparable gain. But value and pleasure are not necessarily identical. We test the hedonic interpretation of loss aversion in experimental markets. With hedonic forecasts, sellers imagine the pain of losing their endowment, and buyers imagine the pleasure of being endowed. With hedonic experiences, sellers rate the pleasure of having the endowment, and buyers rate the pain of being without it. Contrary to loss aversion, predicted pleasure is greater in magnitude than predicted pain, and experienced pleasure surpasses experienced pain. We show that the relative magnitude of pleasure and pain depends on beliefs about the likelihood of outcomes, as well as utilities. Surprise makes gains more pleasurable and losses more painful. With surprising gains and expected losses, pleasure can surpass pain. But when gains and losses are equally likely (or losses are surprising and gains are expected), the opposite pattern can occur. Finally, within‐group and between‐group prices are significantly correlated with hedonic experiences. Sellers who feel better with their endowments assign higher selling prices, and buyers who feel worse about the absence of endowment assign higher buying prices. Despite the fact that hedonic experiences deviate from loss aversion, these emotions predict the endowment effect. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

Recruitment of anterior and posterior structures in lexical-semantic processing: an fMRI study comparing implicit and explicit tasks 总被引:1,自引:0,他引:1
Previous studies examining explicit semantic processing have consistently shown activation of the left inferior frontal gyrus (IFG). In contrast, implicit semantic processing tasks have shown activation in posterior areas including the superior temporal gyrus (STG) and the middle temporal gyrus (MTG) with less consistent activation in the IFG. These results raise the question whether the functional role of the IFG is related to those processes needed to make a semantic decision or to processes involved in the extraction and analysis of meaning. This study examined neural activation patterns during a semantic judgment task requiring overt semantic analysis, and then compared these activation patterns to previously obtained results using the same semantically related and unrelated word pairs in a lexical decision task which required only implicit semantic processing (Rissman, J., Eliassen, J. C., & Blumstein, S. E. (2003). An event-related fMRI investigation of implicit semantic priming. Journal of Cognitive Neuroscience, 15, 1160-1175). The behavioral results demonstrated that the tasks were equivalent in difficulty. fMRI results indicated that the IFG and STG bilaterally showed greater activation for semantically unrelated than related word pairs across the two tasks. Comparison of the two task types across conditions revealed greater activation for the semantic judgment task only in the STG bilaterally and not in the IFG. These results suggest that the pre-frontal cortex is recruited similarly in the service of both the lexical decision and semantic judgment tasks. The increased activation in the STG in the semantic judgment task reflects the greater depth of semantic processing required in this task and indicates that the STG is not simply a passive store of lexical-semantic information but is involved in the active retrieval of this information. 相似文献

In the present study we address a multi‐issue negotiation agenda, where several issues are under consideration and parties have different priorities among these issues. We suggest that in such agendas loss aversion and within issue anchoring may constrain the configuration of offers that parties propose to each other during the course of negotiation. We specifically focus on offers in which negotiators self‐propose to give the other party more than was demanded on one of the issues, while still maintaining or improving their overall value. We term such offers Integrative Gambit Offers (“IGO”s) and show that although making such offers improves integrative negotiation outcome, the frequency of making them is relatively low, and does not increase as negotiators gain experience with the task.

Willingness to help victims unrelated to oneself, in situations where reciprocity is irrelevant, is a common form of altruism. Prior research showed that people are more willing to extend such help when the victims are identified, particularly when the target of help is a single individual. However, in the present research we found that only when the perceivers regard the victims as belonging to their own in-group, willingness to help a single identified individual is greater than willingness to help a group of individuals: identifying tsunami victims by name increased actual contributions only when the specified target was a single compatriot. The role of perceived shared social group in promoting the victim singularity advantage in contributions was mirrored in ratings of emotions, thus supporting an affective account of helping behavior. 相似文献

DECISION AFFECT THEORY: 总被引:9,自引:0,他引:9
Abstract— How do people feel about the outcomes of risky options? Results from two experiments demonstrate that the emotional reaction to a monetary outcome is nor a simple function of the utility of that outcome Emotional responses also depend on probabilities and unobtained outcomes Unexpected outcomes have greater emotional impact than expected outcomes Furthermore any given outcome is lets pleasant if an unobtained outcome is better We propose an account of emotional experiences associated with outcomes of decisions called decision affect theory. It incorporates utilities expectations and counterfactual companions into hedonic responses. Finally, we show that choices between risky options can be described as the maximization of expected emotional experiences as predicted by decision affect theory That is people choose the risky option for which they expect to feel better on average. 相似文献

Latin and Asian-Pacific immigrants are the fastest growing new-comer groups in the U.S. contributing to 85% of immigration totals. New immigrants experience multiple barriers to accessing genetic counseling resulting from cultural, linguistic, financial, and educational factors as well as having unique perceptions on health, illness, reproduction, and life as a whole. In addition, new immigrants lack familiarity with Western medical practices as well as genetic risk and available interventions. We provided perinatal genetic services to 2430 clients, mostly new immigrants of Latin and Asian-Pacific descent over a period of 6 years. Counseling aides sharing the clients' cultural backgrounds were employed. A study assessing the efficacy of cross-cultural education regarding advanced maternal age risk and amniocentesis was implemented and linked to a database containing demographic and clinical information. Practical observations relating to cultural beliefs in the two groups relevant to perinatal genetic counseling were made. 相似文献

Clinical approaches to mood and anxiety disorders in children and adolescents have historically been confined to either diagnosis- [e.g., for obsessive–compulsive disorder vs. generalized anxiety disorder (GAD), etc.] or domain-specific (e.g., for anxiety disorders vs. depressive disorders) treatments. However, as conceptualizations of mental illness shift towards a more dimensional model [e.g., the recent Research Domain Criteria (RDoC) from the National Institutes of Health], transdiagnostic treatments, such as the unified protocol for the treatment of emotional disorders in adolescents (UP-A; Ehrenreich et al. in Child Fam Behav Ther 31(1):20–37, 2008), are gaining support in the empirical literature. This paper reviews the common treatment targets across three emotional disorders commonly found in adolescence: GAD, social anxiety disorder, and major depressive disorder. In particular, similarities and differences across potential treatment mechanisms, including cognitive and information processing deficits, problem-solving difficulties, and avoidance strategies are examined. Finally, the case of 17-year-old “Andrea” is presented to demonstrate how transdiagnostic approaches like the UP-A can be effective in treating a range of emotional disorders in youth. 相似文献
