杏仁核参与加工认知与情绪相互作用的机制

认知与情绪是如何相互作用的已经成为心理学研究领域一个热点话题。自上而下观点将情绪看作一种评价过程,个体需要对动机及所处社会背景信息做出评价,以产生合适的情绪;自下而上观点将情绪看作对刺激特征的感知过程,.并促进随后的再认、记忆和注意等加工过程。社会性情绪、恐惧情绪效价获得与再认、情绪性记忆与注意的研究表明,情绪是一种受到社会背景所影响的自下而上加工(刺激驱动)和自上而下加工(概念驱动)过程交互作用的结果,而杏仁核则是参与这两种加工过程最重要的神经基础。

面孔再认中的同性别偏向及影响因素的综述

面孔再认是社会生活中重要的认知过程,是对保存在长时记忆中的面孔信息的提取。面孔再认包括学习和再认两个阶段。本文对面孔再认中存在同性别偏向现象进行了介绍,并从面孔信息的完整性、面孔的呈现方式、面孔的表情以及加工阶段的注意力四方面论述影响面孔再认中同性别偏向现象的因素,对这一领域的研究进行了综述和展望。     

故事情境下真实记忆与虚假记忆的活动差异

以故事情境为实验材料,采用学习再认实验范式,通过操纵再认靶词与故事情境的关联性考察了情境故事对关联虚假记忆和真实再认神经活动的影响。结果发现：在记忆再认的熟悉性加工和回想性加工阶段,虚假记忆与真实记忆所诱发FN400和LPC成分走向一致;在额叶后提取阶段,虚假再认所诱发的晚慢成分波幅大于真实再认。结果说明：情境性关联虚假记忆与真实记忆表现出相似的熟悉性和回想性加工,但在后期需耗费额外的加工资源进行成功的提取。     

依赖于唤醒与效价的情绪记忆增强效应：自动与控制加工*

情绪记忆增强(Emotionally Enhanced Memory, EEM)效应受到刺激的唤醒度和效价的影响。Kensinger 等人提出依赖于唤醒的 EEM 效应与自动加工相联系,依赖于效价的 EEM 效应与控制加工相联系。然而现有研究并不能为这一假设提供充分的证据。本研究的三个实验采用学习--再认范式和 DA 范式(divided attention paradigm)相结合的方法,分别考察了在两种注意条件下依赖于唤醒和依赖于效价的EEM 效应在编码阶段的加工机制。结果发现,中性词、正性非唤醒词、负性非唤醒词在集中注意条件下的记忆再认成绩显著高于分散注意条件下的记忆再认成绩;正性唤醒词在集中注意条件下的记忆再认成绩也显著高于分散注意条件下的记忆再认成绩,但负性唤醒词的记忆再认成绩在两种注意条件下不存在显著差异。这表明依赖于效价的 EEM 效应与控制加工相联系,而依赖于唤醒的 EEM 效应并不总是与自动加工相联系,其加工还受到情绪效价的调节,对于负性刺激,依赖于唤醒的 EEM 效应与自动加工相联系;对于正性刺激,依赖于唤醒的EEM效应则与控制加工相联系。     

职业生涯高原教师的职业事件编码和再认特点

该研究运用Tversky的社会认知实验范式,对职业生涯高原教师和非职业生涯高原教师在职业生活事件的编码和再认阶段的加工特点进行比较研究。结果发现:(1)职业生涯高原教师比非职业生涯高原教师具有更多的负性编码,存在负性编码偏向;(2)职业生涯高原教师比非职业生涯高原教师具有更多的负性再认,存在负性再认偏向;(3)职业生涯高原教师在编码和再认阶段具有负性的社会认知加工特点。     

整合对联结再认和项目再认的促进作用：“只有收益”观点

研究旨在探讨整合如何影响联结再认和项目再认及其加工过程。编码阶段要求被试学习复合词和非复合词, 提取阶段完成联结再认和项目再认测验。结果显示, 复合词比非复合词有更好的联结再认表现, 但在项目再认表现上两者之间没有显著的差异。ERP结果显示, 在联结再认上, 复合词诱发显著的FN400效应(与熟悉性加工有关)和LPC效应(与回想加工有关), 非复合词只诱发显著的LPC效应, 且复合词比非复合词有更大的LPC效应。在项目再认上, 复合词比非复合词诱发更大的FN400效应。总而言之, 整合在促进联结再认的同时并不会损害项目再认的表现, 支持了“只有收益”观点。     

中国人的群体参照记忆效应

在自我参照效应范式中加入参照认同群体加工任务,比较了中国被试在参照中国人和参照美国人进行记忆加工时的再认率及“记得”与“知道”判断的成绩。两项实验结果一致表明,参照中国人加工的再认成绩显著高于参照美国人,表明记忆加工的认同群体参照效应,而在“记得”与“知道”指标上并无差异;参照中国人加工的再认成绩和“记得”判断成绩显著低于自我参照加工。根据个体自我、关系自我和集体自我的分类方法,自我参照效应反映了个体自我对于记忆加工的影响,群体参照效应则主要反映了集体自我的影响     

再认条件下元监测判断的影响因素

探讨了再认条件下元监测判断的影响因素。以中文双字词对作为实验材料 ,安排在不同预先呈现时间、有无进行有意识记 ,以及不同识记遍数等条件下进行元监测判断。用计算机随机呈现项目 ,再认之前先让被试做元监测判断 ,判断是否是记过的项目的把握程度 ,再对有意识记过的项目做迫选再认 ,作为标准测验 ,以验证元监测判断的准确性。结果是预先呈现时间长、有意识记过的和识记遍数多的项目 ,对其再认的反应时较短 ,相应的元监测判断等级也较高 ;对只看而未有意记过的项目的判断是呈现时间长的判断等级反而低于呈现时间短的。此结果表明 ,再认条件下 ,元监测判断的等级的高低与识记项目的激活程度有关     

多项式加工树模型在再认启发式中的应用

摘 要 再认启发式利用再认线索进行决策。以往研究采用一致率、击中率、虚报率和区分指数来表示再认启发式使用,然而这些方法都存在局限。多项式加工树模型能够分离不同的认知加工过程,为了解决再认使用与知识使用的混淆,研究者提出一种多项式加工树模型 r-model 测量再认启发式的使用。本文将重 点介绍 r-model,具体包括 r-model 的内容、数据分析以及考虑个体差异的分层 r-model。最后,从 r-model 的模型修正和边界条件两个方面提出未来研究方向。 关键词 再认启发式;流畅启发式;多项式加工树;贝叶斯分层模型     

The fluency of social hierarchy: the ease with which hierarchical relationships are seen, remembered, learned, and liked

We tested the hypothesis that social hierarchies are fluent social stimuli; that is, they are processed more easily and therefore liked better than less hierarchical stimuli. In Study 1, pairs of people in a hierarchy based on facial dominance were identified faster than pairs of people equal in their facial dominance. In Study 2, a diagram representing hierarchy was memorized more quickly than a diagram representing equality or a comparison diagram. This faster processing led the hierarchy diagram to be liked more than the equality diagram. In Study 3, participants were best able to learn a set of relationships that represented hierarchy (asymmetry of power)--compared to relationships in which there was asymmetry of friendliness, or compared to relationships in which there was symmetry--and this processing ease led them to like the hierarchy the most. In Study 4, participants found it easier to make decisions about a company that was more hierarchical and thus thought the hierarchical organization had more positive qualities. In Study 5, familiarity as a basis for the fluency of hierarchy was demonstrated by showing greater fluency for male than female hierarchies. This study also showed that when social relationships are difficult to learn, people's preference for hierarchy increases. Taken together, these results suggest one reason people might like hierarchies--hierarchies are easy to process. This fluency for social hierarchies might contribute to the construction and maintenance of hierarchies.     

Social status as a cue for tacit coordination

The present paper investigates how and when social status may serve as a cue for tacit coordination. In three experimental studies, we demonstrate that low status individuals are inclined to defer to the preferences of high status individuals, thereby facilitating coordination success. Furthermore, we investigate the boundary conditions of this effect. More specifically, we show that social status only facilitates coordination success when the people involved have asymmetric (or conflicting) preferences (Study 2), and when there is a clear social hierarchy (Study 3). In the general discussion, we relate these findings to earlier research on dominance hierarchies, social power, deference and perspective-taking and we provide suggestions for future research.     

The Challenge of Being a Challenger: Social Dominance Orientation Shapes the Impact of “Challenger vs. Leader” Comparisons

The current research investigates when and how comparative advertising effectiveness is shaped by social dominance orientation (SDO), that is, the degree to which one desires to maintain the status quo in social hierarchies. We examine these issues with regard to “challenger vs. leader” comparisons that seek to change the relative standing of competitors in a product category by documenting the superiority of challenger brands over market leaders. Findings demonstrate that the resistance to change characterizing high (vs. low) SDO individuals makes them respond (1) less favorably to “challenger vs. leader” comparisons that seek to alter the existing category hierarchy and (2) more favorably to “leader vs. challenger” comparisons that preserve this status quo in the category hierarchy. The theoretical implications of these findings are discussed, as are avenues for future research.     

Interpersonal hierarchy expectation: introduction of a new construct

The goal of these series of studies was to introduce a new individual difference construct, interpersonal hierarchy expectation (IHE), and to show that it predicts interpersonal perception. IHE means expecting social interactions and relationships to be hierarchically structured. I developed a self-report questionnaire to measure IHE (IHE Scale [IHES]). In 5 studies, 581 undergraduates took the IHES together with an array of self-report personality measures. Three studies included a measure of hierarchy perception. According to prediction, people who expected interpersonal hierarchies were prone to perceive hierarchies in interactions and relationships. The IHES is an easy to apply, short, self-report measure that might prove useful in personnel training and selection as well as in other studies of personality and social behavior.     

Are male tokens bad for females? The effect of social dominance orientation on high‐status tokens' evaluations of low‐status members

Prior research has not given much attention to understanding how those in the numeric minority (i.e., tokens) with high social status (e.g., males) react to those with low social status (e.g., females). We draw from social dominance orientation (SDO) to better understand how male tokens' beliefs about group‐based hierarchies affect their evaluation of a highly qualified female candidate. We conducted a laboratory study in which participants were placed in a selection situation and were asked to evaluate a highly qualified female candidate. We discovered a significant interaction between token status and SDO such that male tokens who were high in SDO were more likely to evaluate negatively a highly qualified female.     

Social dominance and interpersonal power: Asymmetrical relationships within hierarchy‐enhancing and hierarchy‐attenuating work environments

We studied whether high‐social dominant employees sustain hierarchies in different hierarchy‐enhancing and hierarchy‐attenuating organizations endorsing harsh and soft power tactics. We found that social dominance orientation was positively associated with harsh power tactics, and negatively associated with soft power tactics. Employees higher in social dominance orientation endorsed harsh and opposed to soft power tactics as respectively hierarchy‐enhancing and hierarchy‐attenuating legitimizing myths that promote a dominant‐submissive form of intergroup relationships. We also found that supervisors higher in social dominance, due to their dominant position, strongly opposed soft power tactics more than subordinates did. Amongst high‐social dominant employees in the hierarchy‐attenuating (vs. hierarchy‐enhancing) organization, we observed the strongest opposition to soft power tactics, which are the tactics most shared in an organization which tends to attenuate hierarchies.     

Child psychopathology and deviant family hierarchies

The association between child psychopathology and reversals in family hierarchies (where the child is seen as equal or higher in the hierarchy than the parental figures) were examined with the Madanes Family Hierarchy Test on a sample of 177 clinic-referred boys. Madanes' original findings of the association of substance use and deviant family hierarchy were replicated in this younger sample, (age 7 to 12). Boys diagnosed with Conduct Disorder reported significantly more deviant hierarchies while boys diagnosed with Overanxious Disorder reported significantly fewer deviant hierarchies. Follow-up results revealed some instability and lack of informant agreement, but the hierarchy measure was not confounded by age, race, SES, IQ, or parents' marital status.     

Dominance status predicts social fear transmission in laboratory rats

Acquiring information about stimuli that predict danger, through either direct experience or inference from a social context, is crucial for individuals’ ability to generate appropriate behaviors in response to threats. Utilizing a modified demonstrator–observer paradigm (fear conditioning by proxy) that allows for free interaction between subjects, we show that social dominance hierarchy, and the interactive social behaviors of caged rats, is predictive of social fear transmission, with subordinate rats displaying increased fear responses after interacting with a fear-conditioned dominant rat during fear retrieval. Fear conditioning by proxy conserves some of the pathways necessary for direct fear learning (e.g., lateral amygdala) but is unique in that it requires regions necessary for emotional regulation (e.g., anterior cingulate cortex), making this paradigm an important tool for evaluating learning and behavior in the laboratory setting.     

Pride and punishment: Entitled people's self‐promoting values motivate hierarchy‐restoring retribution

What is the purpose of punishment? The current research shows that for entitled people—those with inflated self‐worth—justice is about maintaining societal hierarchies. Entitled people more strongly hold self‐enhancing values (power and achievement; Studies 1 and 3). They are also more likely, when thinking about justice for offenders, to adopt a hierarchy‐based justice orientation: Perceptions that crime threatens hierarchies, motives to restore those hierarchies, and support for retribution (Studies 2 and 3). Further, the relationship of entitlement to justice orientation is mediated by self‐enhancing values when entitlement is measured (Study 3) and manipulated (Studies 4, 5 and 6). Together these studies suggest that entitlement—and the resultant preoccupation with one's status—facilitates a view of justice as a hierarchy‐based transaction: one where criminal offenders and their victims exchange power and status. These findings reveal the self‐enhancing and hierarchy‐focused nature of entitlement, as well as the roots of retribution in concerns about status, power, and hierarchies.     

Classroom‐ and School‐Level Contributions to Bullying and Victimization: A Review

School bullying is increasingly viewed by researchers as a group phenomenon that extends beyond the perpetrator–victim dyad and is embedded in the wider social context. This paper reviews the literature on classroom and school factors contributing to bullying and victimization among children and adolescents. Considerable variability in the prevalence of these problems exists between classrooms and schools, which are highly relevant contexts for students' social development. Along with individual characteristics, both classroom‐ and school‐related factors explain the bullying dynamic. The contexts may also exacerbate, or buffer against, the effects of individual‐level risk for bullying involvement and the consequences of victimization. We discuss findings on the contributions of demographic and structural characteristics (e.g. grade level, classroom and school size), peer contextual factors (e.g. status hierarchy, group norms and bystander behaviours) and the role of teachers. Finally, implications for research and school‐based antibullying programs are considered. Copyright © 2014 John Wiley & Sons, Ltd.
