自我效能感和认知风格对刻板印象激活效应的影响

通过两个实验考察了自我效能感与认知风格在刻板印象激活效应(个体刻板印象的激活会影响个体随后的行为表现,使之符合所激活的刻板印象)中的作用,初步探讨了刻板印象的激活引发行为改变的内在心理机制。实验1采取单因素被试间实验设计,将被试随机分配到实验组和控制组,接着完成智力测试与自我效能感评价任务。结果发现自我效能感在刻板印象激活效应对于智力测试成绩的影响中起着中介作用。在此基础上,实验2进一步纳入认知风格,首先对被试的握力进行前测,1周后再将被试随机分配到高耐力组和低耐力组进行再测。结果表明:自我效能感在刻板印象激活引发的行为表现中依然起着中介作用。与此同时,虽然场依存的被试更易受刻板印象激活效应的影响,而场独立的被试则不易受到这种情境的影响,但是认知风格未起到中介作用。     

社会认知双加工视角下的刻板印象激活机制

刻板印象激活过程中意识干预与否的问题,催生了内隐与外显两种激活理论长久以来的争端。其根源在于现有研究的刻板激活操作不严谨、两类范式不可比等多个方面。社会认识双加工理论提供了独特的分阶段比较视角。在该理论视角下,文章从梳理内隐及外显理论争端入手,分析各自存在的问题,并以双加工理论为指导,设计了一项内隐及外显任务分离启动研究,以期为探明刻板印象的认知激活机制,提供方法上的支撑。     

“父母激活”理念及其临床意义

运用Rodgers演化概念分析法对父母激活的概念、属性特征、替代术语和相关术语、先决条件和影响因素、结果和意义以及测评指标进行分析,并揭示其在儿科护理领域的临床价值和意义。概念属性包含信念、知识、能力和信心４个维度。先决条件和影响因素包括父母受教育程度、婚姻状况、孩子病程长短和医疗保健服务提供者是否为父母提供激活干预措施等。结果和意义包括提升患儿健康相关结局、提升父母照护孩子的信心、减轻父母心理压力以及促进卫生系统和社区资源的有效利用等。澄清父母激活这一理念的内涵有助于提高医护人员对其的了解与重视,为后续父母激活干预措施的提出和践行提供一定的理论依据。

     

重复启动条件下语义启动效应减少的机制

采用重复启动范式探讨语义启动效应减少的机制。结果发现,在SOA为短的167ms条件下,重复/相同和重复/相关的启动效应无差异,且重复/相关启动并未导致语义启动效应的减少;而在SOA为长的1200ms条件下,重复/相同和重复/相关的启动效应差异显著,且重复/相关启动导致了语义启动效应的减少,而重复/相同未导致语义启动效应的减少。在抵消了期望和消退的作用后,在SOA为1200ms条件下所得到的重复/相同和重复/相关启动效应的差异,是由于扩散受到了阻碍而导致的。这一结论支持了激活扩散是有一定条件的观点。     

亚词汇水平加工的本质:形旁的语音激活

该研究利用启动命名技术,探讨了汉字加工时是否存在着形旁的语音激活。把含有独立成字的形旁的合体字（如“躲”）作为启动字,与形旁同音的字（如“深”）作为目标字。结果发现,当合体字是低频字时,目标字的命名速度显著加快。高频合体字则没有此效应。集合Ｚｈｏｕ和Ｍａｒｓｌｅｎ－Ｗｉｌｓｏｎ关于声旁语义激活的研究,该文得出结论说,汉字亚同汇水平的加工与词汇水平的加工表现一样,两者之间并无本质性的差别。     

关系持续预期与规范目标激活：合适性逻辑下的信任决策

人际互动过程中,信任作为决策过程受到诸多因素的影响,信任的决策逻辑在不同的研究背景中存在冲突。本研究以合适性为信任决策框架,互动关系为激活规范目标的变量,分析了存在互动关系持续预期和不存在互动关系持续预期对信任行为的影响及其影响机制。结果表明：（1）被试间存在关系持续时,信任水平较高;关系持续预期消失时,信任水平显著下降。（2）被试对关系持续的重要性感知与其信任决策显著相关。（3）情境中的目标未被激活时,个体的信任倾向与信任决策显著相关;而当情境目标被激活时,信任倾向与信任决策相关不显著。     

An inter-hemispheric imbalance in the psychopath’s brain

Psychopathy is associated with two extremities. On the one hand, psychopathic individuals lack any concern for social norms and they are severely poor in maintaining healthy social relationships. In addition, the ability of individuals with psychopathy to feel certain emotions such as empathy, guilt or fear is seriously compromised. In contrast to these deficits, some behaviors and tendencies are exaggerated in psychopathy. For instance, psychopathic individuals display higher than normal impulsivity, stimulation-seeking, aggression and risk-taking. There are indications in the literature that pro-social behavior, as well as the feelings of empathy, guilt and fear are mediated predominantly by regions within the right hemisphere (RH), whereas impulsivity, stimulation-seeking, aggression and risk-taking are linked primarily with left hemisphere (LH) activity. From a neurobiological perspective, it seems that psychopathy may be associated with an altered and imbalanced inter-hemispheric dynamics; a relatively hyperfunctioning LH and/or a hypofunctioning RH. Furthermore, within the psychopathic population, the RH hypofunctioning is more characteristic of primary psychopathy with its affective and interpersonal deficits, while the LH hyperfunctioning is most typical of the secondary psychopathy which is marked by impulsivity and antisocial style.     

Self-regulation during a single performance episode: Mood-as-information in the absence of formal feedback

This investigation used a daily diary methodology to examine goal revision and effort allocation processes over a single, 2-weeks performance episode in which individuals prepared for a course exam. Growth curve modeling revealed that daily goal exhibited a curvilinear trend in which it was stable and relatively high at the beginning of the time period, but rapidly declined as the exam approached. Daily effort exhibited a trend opposite of the goal trend, remaining low and relatively stable at the beginning and increasingly rapidly as the exam approached. Current mood predicted daily goal revision, with positive mood being positively related to goal revision and negative mood being negatively related to goal revision. The traits of behavioral activation system (BAS) sensitivity and behavioral inhibition system (BIS) sensitivity moderated within-person relationships of positive and negative mood with goal revision. Simultaneous and lagged relationships among mood, goals, and daily effort were also examined.
