The Effect of Decision Strategy on Deciding to Defer Choice

Recent research has examined consumer decision making when the option of not choosing any of the alternatives is also provided. The findings from this research suggest that the decision to defer choice is sensitive to the uncertainty of choosing the most preferred option from the set of alternatives provided. Building on this research, the author tests whether the decision to defer choice is also influenced by task variables that influence decision uncertainty. In the first experiment, this proposition is tested for choice problems in which information on three relatively equally attractive alternatives is presented either sequentially or simultaneously. As predicted, the preference for the defer-choice option was greater when the three alternatives were presented simultaneously. A second study forced subjects into using one of four decision strategies in order to choose between two non-dominated alternatives. The preference for the no-choice option was found to be higher when the rule required explicit attribute tradeoffs and lower when it simplified choice. These results suggest that choice uncertainty is influenced by the decision strategy used to determine the preference among alternatives. We conclude with a discussion of the implications of the results for marketers' communication strategies.     

高校辅导员的边界分割偏好与工作-非工作冲突:边界分割管理策略的调节作用

采用问卷调查法,对312名高校辅导员进行调查,探讨边界分割偏好、组织分割供给和个人边界分割策略与工作-非工作冲突的关系。结果表明:(1)辅导员的边界分割偏好与工作-非工作冲突正相关;(2)组织分割供给和个人边界分割策略均能减弱边界分割偏好与工作-非工作冲突之间的正相关。本研究提示高校应在不影响工作的前提下尽量向辅导员提供更多的组织分割供给,同时辅导员也可以通过灵活运用边界分割策略,进行自主的工作-非工作边界管理。     

学步儿童的不顺从行为与亲子互动的关系

通过对138名学步儿童及其母亲的观察研究,分析儿童的不顺从行为与亲子互动之间的关系。结果表明:(1)在亲子互动中,母亲的言语策略多于身体策略。(2)母亲的模糊言语显著地正向预测儿童的反抗,母亲的远处身体指导显著地正向预测消极不顺从。(3)母亲的反应性与明晰言语、模糊言语、积极身体指导和远处身体指导正相关,与严厉言语和消极身体指导负相关。(4)儿童反应性负向预测消极不顺从和拒绝/协商行为。     

儿童在生词阅读中对类推策略应用的研究现状

字形与字音对应关系的类推策略在儿童开始学习阅读时是否已经存在;如果存在,类推发生于单词的什么位置;另外,这种类推能力是逐渐增长的,还是保持不变的。上述问题是20年来关于生词阅读策略研究的核心问题。从2位代表性人物Goswami和Bowey的研究入手,文章回顾并分析了针对上述问题的研究历程,展示了现有争论的方法论根源,同时对一些新的研究趋势进行了分析和展望。     

儿童图形识别取样的时空策略

本研究探讨儿童图形识别取样的时间和空间策略。被试为24名六年级学生和24名三年级学生,刺激材料为20个不规则无意义几何图形。结果发现:六年级学生采取取样空间扩展为主,取样时间调整为辅的策略,三年级学生采用增加取样时间为主,扩展取样空间为辅的取样策略。任务难度加大时,被试采用恒定取样点时间和增加取样点数目的时-空策略。在空间取样策略发展上,学生年龄和任务难度的交互影响显著。     

浅谈脂肪肝的诊治策略

脂肪肝已成为威胁国人健康仅次于病毒性肝炎的第二大肝病。通过对脂肪肝发病机制、发病原因、诊断方法和防治措施的深入研究,能够确定行之有效的诊治策略。针对病因和(或)诱因进行预防,走出在脂肪肝治疗上的误区,对遏制脂肪肝的日益严重的发病趋势和降低医疗费用有着十分重要的意义。     

Covenants and reputations

In their classic analyses, Hobbes and Hume argue that offensively violating a covenant is irrational because the offense ruins one’s reputation. This paper explores conditions under which reputation alone can enforce covenants. The members of a community are modeled as interacting in a Covenant Game repeated over time. Folk theorems are presented that give conditions under which the Humean strategy of performing in covenants only with those who have never offensively violated or performed with an offensive violator characterizes an equilibrium of the repeated Covenant Game. These folk theorems establish that for certain ideal settings Hobbes’ and Hume’s arguments against offensively violating covenants are compelling. However, these ideal settings presuppose that the community has certain mechanisms that generate common knowledge of the identities of those with whom one should perform. I analyze the results of computer simulations of the interactions in a community whose members must rely upon private communication alone. The computer simulation data show that in this community, reputation effects cannot effectively deter members from offensively violating covenants. I conclude that Hobbes’ and Hume’s warnings against offensive violation are compelling only on condition that the community is sufficiently structured to generate common knowledge among its members. I also conclude that even in such structured communities, the Humean strategy is not the uniquely “correct” policy.     

Personality,reciprocity, and strength of conflict resolution strategy

The present field study investigates how an individual’s interpersonal conflict resolution behavior is affected by the individual’s personality (assessed by the Big 5) and a situational factor (the other party’s conflict behavior), as well as how the two factors interact. A hierarchical regression analysis based on 256 student–roommate/friend dyads shows that both factors are important. Extraversion and Agreeableness were significantly related to most conflict strategies used by students. The results show that interactions between the parties in conflict situations are strongly governed by the norm of reciprocity. Finally, we found some empirical support for the interaction effect between personality and situation, suggesting that an individual’s conflict behavior is more complex than what the dispositional or the situational view may suggest.     

诊断认知策略的几何类比推理测验题的特征及其编制研究

该文在新一代测验理论的视角下,以几何类比推理测验为研究对象,以认知策略的诊断为目的,研究更能引发被试的规则构建策略或选项剔除策略的项目的特征。研究结果表明,项目中元素数量是影响被试使用规则构建策略或选项剔除策略的关键因素,元素数量越多时越倾向于用规则构建策略,而元素数量越少时倾向于用选项剔除策略。研究结果可直接用于测验设计,使得测验能更多在某一策略的框假下分析描述被试特征。
