Three experiments are presented that explore the assertion that loss aversion and diminishing sensitivity drive the effect of experience on choice behavior. The experiments are focused on repeated choice tasks where decision makers choose repeatedly between alternatives and get feedback after each choice. Experiments 1a and 1b show that behavioral tendencies that were previously interpreted as indications of loss aversion in decisions from experience are better described as products of diminishing sensitivity to absolute payoffs. Experiment 2 highlights a nominal magnitude effect: A decrease in the magnitude of the nominal payoffs eliminates the evidence for diminishing sensitivity. These and related previous results can be captured with a model that assumes reliance on small samples of subjective experiences, and an increase in diminishing sensitivity with payoff variability.

在多重系统理论研究基础上,运用即时反馈训练范式,以大学生为被试,考查相关维度数量对基于规则和信息整合两种结构的类别学习的影响.结果表明:(1)相关维度数量是影响类别学习的重要因素,基于规则单维度结构的学习显著优于信息整合结构和基于规则双维度结构的学习,基于规则双维度结构的学习与信息整合结构的学习没有显著差异.(2)反应策略受到规则复杂性的影响,当类别结构中隐含的规则比较简单时,学习者使用规则策略;当类别结构中隐含的规则比较复杂时,学习者难以掌握规则,就会使用相似性策略.研究结果支持"难度观",而不支持多重系统理论. 相似文献

Changes in migrants' backgrounds and societies sending and receiving migrants might increase adaptation issues and reduce retention. To enhance migrants' well‐being/health and their likelihood of staying it is necessary to gain an understanding of psychological and social factors that contribute to resilience and adaptation. This paper presents findings from a qualitative study that investigated the experiences, interpretations and actions of German migrant couples to New Zealand throughout the whole migration process to identify these factors. In depth, episodic interviews were conducted with four couples who decided to stay in New Zealand and four couples who decided to return to Germany. Interview data were complemented with participant observation. This paper provides insights into how the pre‐migration experiences, interpretations and actions of German migrants to New Zealand influenced their establishment, their interpretations and actions and consequently adaptation, well‐being/health and the decision whether to stay in New Zealand or to return to Germany. The findings illuminate the influence of psychological and social factors on migration experiences, interpretations and actions throughout the migration process. The paper offers some solutions for addressing the identified barriers to successful migration and integration into host societies. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

The most original aspect of Hedwig Conrad-Martius’ research is her interpretation of nature, performed through the phenomenological
method. She pinpoints the very essences of the natural phenomena, discovering entelechies inside them and a trans-physical
dimension. She reads the evolution of nature in a new way, against the deterministic interpretation of it. Inside nature one
can discover many levels, qualitatively different. The human being participates to all of them, but his/her peculiarity is
linked to the mental–spiritual life. 相似文献

According to classical decision theory, an agent realises at time t the option with maximum expected utility (determined by his beliefs and desires at t), where the relevant options are possible actions performed at t. I consider an alternative according to which the relevant options are in general plans, complex courses of action extending into the future. 相似文献

Recent and puzzling experimental results suggest that people’s judgments as to whether or not an action was performed intentionally
are sensitive to moral considerations. In this paper, we outline these results and evaluate two accounts which purport to
explain them. We then describe a recent experiment that allegedly vindicates one of these accounts and present our own findings
to show that it fails to do so. Finally, we present additional data suggesting no such vindication could be in the offing
and that, in fact, both accounts fail to explain the initial, puzzling results they were purported to explain.
