注意资源、学习方式与年龄因素对协作抑制的影响

本研究在前人研究的基础上,试图探讨不同编码因素对协作抑制效应的制约作用,从协作抑制角度为挖掘集体记忆的作用机制提供证据。实验1结果发现,集中注意条件下,出现协作抑制;分配注意条件下,协作抑制消失。说明学习时注意资源的投入程度,对协作抑制有影响。实验2结果发现不同的学习方式对协作抑制的影响在不同年龄被试身上表现不同。本研究将视角聚焦于编码因素,研究结果证实,协作抑制受到不同编码因素的制约,此外,本结果亦为协作抑制的提取策略破坏假说提供了新的证据。     

情绪调节效应的发展:一个V型发展趋势

从青少年早期到成人早期,个体情绪调节等高级社会认知功能得到进一步完善,对情绪调节的需求也日趋增长。情绪调节的发展是青少年情绪社会化发展一个重要的任务,学会采用有效的调节策略对自身情绪进行调节是青少年社会性发展的一个重要表现。在众多关于青少年社会行为研究中,对负性情绪调节能力的探究最为成熟与深入。以往研究指出,儿童青少年对负性情绪的体验激活和调控失败都是导致其非适应性行为的原因,情绪调节方式的错误选择会与其外化行为问题和和内化行为问题有很大的关联。由于青少年适应性行为的习得是多种社会性发展指标的重叠和交叉作用的体现,我们无法完全理清其中的复杂交互作用,因此从情绪调节策略的使用效应发展入手探讨个体的适应是寻求问题解决的一个可行手段。 以往研究者认为,成熟且有效的情绪调节指的是,个体能够通过控制自身的激活和唤醒以达到情绪性、生理性和社交的适应,最后达成个人的目标。情绪调节的发展也可被看作是从被动式的、有他人参与的调节（例如,社会性参照）逐渐进步为主动的、有意识的根据外部线索进行的情绪调节（例如,根据指导语提示调整自己情绪状态）。 本研究旨在探究不同年龄被试（青少年早期、青少年晚期、成人早期）在按照不同指导语提示要求下增强调节和减弱调节调节效应量的年龄差异。选取上海市初中生被试35名（22男,13女;M = 14.06岁,SD = 0.42 岁, 年龄范围：13-15岁）、高中生被试37名（13男,24女;M=16.56岁, SD=0.56岁, 年龄范围：16-18岁）以及成人被试35名（9男,26女;M = 23.60岁,SD = 1.96岁, 年龄范围：20-29岁）,采用3（年龄：初中生、高中生、成人,被试间变量）? 3（情绪刺激：正性、中性、负性,被试内变量）? 3（调节策略：增强调节、减弱调节、不调节,被试内变量）混合实验设计,使用情绪反应性—调节图片任务（Reactivity and Regulation-Image Task,REAR-I Task）对不同年龄被试情绪调节策略使用的效应量进行考察（Carthy, Horesh, Apter, Edge, & Gross, 2010）。 研究发现,从总体趋势来说,情绪调节策略的效应发展呈V型发展趋势。当不同年龄被试按照指导语要求对其情绪体验进行主动调节时,成人被试的调节效应是最大的,初中生次之,而高中生的调节效应则最低。情绪调节的V型发展趋势与以往研究中关于情绪调节态度以及自我发展的趋势相一致。另外,与增强调节策略的使用相比,减弱调节策略效应的发展是最大的。这可能与中国背景下减弱调节的适应价值有关。     

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。

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.
