The act of rejecting reduces the desire to reconnect: Evidence for a cognitive dissonance account

Through three experiments we examined whether the act of rejecting reduces the desire to reconnect with others. In Experiment 1, female participants who had just rejected a job applicant were less motivated to make new friends than the controls. In Experiment 2, female participants who had insufficient justifications to reject a paper were more reluctant to work with others than those who had sufficient justifications to reject. In Experiment 3, high-choice female participants showed more reduction in reconnecting desire than low-choice female participants. Furthermore, female participants who could misattribute their discomfort away showed less reduction in reconnecting desire. However, in all three experiments, male participants showed less reduction in reconnection desire than females. A follow-up survey showed that males and females differed in their senses of social connectedness and their different discomfort level at rejecting others. Overall, results supported the cognitive dissonance account which posits that, because the act of rejecting is in conflict with the fundamental motive to affiliate, such conflict may compel the mind to modify the existing attitude. Thus rejecting reduces the desire to forge new social connections.

基于啮齿类动物的决策行为研究及其脑机制

介绍了近年来以啮齿类动物为对象,关于决策的行为表现及其内在脑机制的研究进展。首先介绍了决策的概念,以及啮齿类动物的决策模型。在这些模型的基础上,总结了不同决策模型的共同的心理过程：计算、动机和记忆,并且介绍了业已发现的参与这些心理机制的脑机制。最后,还从决策的角度探讨了其与药物成瘾之间的关系,包括成瘾药物对决策行为的影响以及决策个体差异与药物成瘾易感性之间的关系     

LGM模型中缺失数据处理方法的比较:ML方法与Diggle-Kenward选择模型

追踪研究中缺失数据十分常见。本文通过Monte Carlo模拟研究,考察基于不同前提假设的Diggle-Kenward选择模型和ML方法对增长参数估计精度的差异,并考虑样本量、缺失比例、目标变量分布形态以及不同缺失机制的影响。结果表明:(1)缺失机制对基于MAR的ML方法有较大的影响,在MNAR缺失机制下,基于MAR的ML方法对LGM模型中截距均值和斜率均值的估计不具有稳健性。(2)DiggleKenward选择模型更容易受到目标变量分布偏态程度的影响,样本量与偏态程度存在交互作用,样本量较大时,偏态程度的影响会减弱。而ML方法仅在MNAR机制下轻微受到偏态程度的影响。     

中文阅读中副中央凹语义信息的提取：来自ERPs的证据

书面语言阅读过程中, 关于读者能否提取预视词汇的语义信息, 以往的研究仍有争议。鉴于边界技术在研究该问题时具有无法严格控制预视词呈现时间等一些局限性, 近年来有研究者利用ERPs技术结合伴侧RSVP范式对拼音语言中的语义预视效应进行研究。本研究首次将这一方法应用到中文句子阅读中, 并对实验材料进行了更严格的控制, 保证关键屏(目标名词位于右侧副中央凹处)内容在实验条件间完全相同, 避免以往类似研究中关键词自身属性信息对实验结果产生干扰。ERPs数据分析发现, 在关键屏呈现后, 语义违背相比合理条件诱发了更大的N400成分, 而关键后屏(目标名词位于中央凹处)呈现后, 两种条件间的N400成分无显著差异。该结果支持中文句子阅读中预视词汇语义信息可以得到提取, 并参与随后的语义整合过程。     

Be loyal but not addicted: Effect of online game social migration on game loyalty and addiction

To increase game loyalty but decrease game addiction, this study examines online game social migration and tests the mediating effects of offline social value and maladaptive cognition on the basis of the theory of consumption value and the cognitive behavioral model of pathological Internet use. The results are as follows: (i) Overall, online game social migration is associated with greater game loyalty and less game addiction; (ii) The positive association between online game social migration and game loyalty was mediated by offline social value; and (iii) Online game social migration is associated with lower game addiction. This paper provides a new perspective (taking into account both business interests and players' psychological health) for online game research and also offers practical guidance for cooperation between game companies and the public.

不同相关线索下海洛因成瘾者的反应差异及反应抑制特征：来自ERP的证据

采用ERP技术, 探究海洛因成瘾者在不同相关线索下的脑电反应及其与冲动性的关系。实验采用组间实验设计和双选择Oddball范式, 要求海洛因成瘾组和健康对照组被试对标准刺激与偏差刺激分别做不同的按键反应, 记录他们的EEG数据。结果发现：相比对照组被试, 海洛因成瘾者在观看药物相关线索时诱发的N2波幅更小, P3波幅更大; 在成瘾组内, 相比用药工具线索, 用药动作线索诱发了更小的N2波幅和更大的P3波幅。这表明海洛因成瘾者对药物相关线索存在反应抑制缺陷, 且不同的药物相关线索会激发海洛因成瘾者不同程度的反应抑制缺陷, 用药动作线索比用药工具线索更大程度地影响成瘾者的反应抑制能力, 反映出更高的动作冲动性。
