医患沟通对医生刻板印象表达的影响

从沟通频次与刻板印象传递性质的关系入手,以住院患者和尚未成为住院患者的大学生为被试,采用系列再生范式,利用10条4人再生链,探讨了医患沟通频次对医生刻板印象表达的影响。结果显示,与医生沟通频次高的住院患者在再生链的第2个位置传递医生的积极信息高于消极信息,但是经过4人的传递,住院患者对医生刻板印象信息的传递在积极信息与消极信息没有差异。而与医生沟通频次低的大学生在再生链的后期表现出传递医生消极信息的倾向。该结果表明：沟通频次能够调节有关医生的消极刻板印象的传递—与医生沟通频次高的群体在传递医生的刻板印象信息时,在传递的早期具有积极的倾向性;但经过多人传递之后,在效价方面已经没有倾向性;与医生沟通频次低的群体倾向于传递医生刻板印象的消极信息。     

情感一致性对刻板印象激活的影响

情感一致性是指情感具身反应(情感感受、表情及情感的相关身体动作等)和情感认知评价(情感观念性内容,积极或消极)在效价层面上的耦合关系。实验以89名大学生为被试,考察了情感一致性对(性别)刻板印象的影响。实验通过音乐启动相应的情感感受(积极或消极)操纵情感具身反应,采用快速组句任务启动相应的情感信念(积极或消极)操纵情感认知评价,89名被试被随机分配到四种实验条件下,最后所有被试参与(性别)刻板印象IAT测验。结果发现:情感不一致条件促进(性别)刻板印象激活;情感一致性没有导致流畅性的变化;情感感受调节了消极阈下情感信念对刻板印象激活的作用。     

情绪对内隐刻板印象表达的调节

采用IAT范式探讨不同情绪对内隐刻板印象表达的调节作用：实验1通过音乐唤醒被试的不同弥散性情绪状态(悲伤vs.愉悦), 并操纵其即时观念(刻板一致vs.刻板冲突), 探讨二者对内隐性别刻板印象表达的影响。实验2通过视频诱发被试不同的指向性情绪(同情vs.厌恶), 研究其如何调节大学生对不同感染途径的艾滋病患者和病毒携带者的内隐刻板印象表达。在此基础上引入四重模型(Quad Model)分析技术, 进一步细化情绪的调节作用究竟发生在认知加工的自动加工过程还是控制加工过程, 以及不同情绪是通过哪些心理成分调节内隐刻板印象的表达。结果表明：(1)当即时观念与刻板印象内容一致时, 积极弥散性情绪促进内隐刻板印象的表达; 反之则会抑制其表达; (2)弥散性情绪通过调节认知加工的自动化加工过程, 进而调节内隐刻板印象的表达, 但未参与调节控制性加工过程; (3)积极效价的指向性情绪会抑制被试对艾滋病患者的内隐刻板印象表达, 消极效价的指向性情绪会促进其表达; (4)指向性情绪通过自动激活成分, 调节内隐刻板印象表达的自动化加工过程; 同时也通过辨识力成分, 参与调节内隐刻板印象表达的控制性加工过程。     

知觉冲突印象形成的认知控制策略：以刻板化信息与反刻板化信息为例

以刻板化信息与反刻板化信息为例,采用词义Stroop范式和掩蔽版的目标-启动范式分别将实验任务分成高、低知觉负载或阈上、阈下启动两种水平,考察冲突信息知觉负载水平及其强度对他人印象形成的认知控制策略的影响。结果发现:(1)冲突信息启动方式与知觉负载的动态变化决定了个体对刻板化信息与反刻板化信息印象形成的认知控制策略。反应性控制耗费的认知资源少,对刻板一致化信息的印象加工更快捷,而对刻板冲突化信息的印象加工更缓慢,且易激活反刻板印象;而主动性控制耗费的认知资源多,对刻板一致化信息的印象加工更缓慢,而对刻板冲突化信息的印象加工更快捷,且易出现刻板印象偏差。(2)认知控制对刻板化信息与反刻板化信息采取不同的加工模式。刻板化信息与反刻板化信息同时在阈上启动时,其加工方式受到有意操作系统的主动性控制,即进行可意识到的、受意识控制的加工;而当这两类信息同时在阈下启动时,其加工方式受到自动监控系统的反应性控制,即进行无意识的、不受意识控制的加工。这些结果表明,个体通过所知觉到的刻板化信息与反刻板化信息,能灵活地在两种认知控制系统(有意操作系统vs.自动监控系统)中进行权衡,调节其权重(即,要么启动主动性控制,要么偏向反应性控制),从而形成最有利于他人的印象加工策略。即便处于知觉阈限之下,个体仍能通过无意识认知控制的方式对他人印象进行加工。     

群体关系对不同效价刻板印象信息传递的影响：系列再生法的证据

采用系列再生法探讨了群体关系对不同效价刻板印象信息传递的影响,共包括2个实验。实验1通过8条4人再生链传递信息,探讨了被试与靶子的群体关系对不同效价刻板印象信息传递的影响;实验2通过16条4人再生链传递信息,探讨了被试与靶子及听众的群体关系对不同效价刻板印象信息传递的影响。结果显示：个体更容易传递内群体的积极刻板印象信息和外群体的消极刻板印象信息,群体关系不同则被试对刻板印象信息的传递就不同。结论：不同效价的刻板印象信息其传递具有选择偏向,并且这种选择偏向会随着沟通者、靶子及听众间关系的变化而变化。     

元刻板印象的效价与效应相回馈吗?

元刻板印象的效价有积极和消极之分, 其效应也存在积极和消极之别。然而, 目前关于元刻板印象效价与效应的关系还存在争议。元刻板印象的威胁效应和促进效应遵从回馈原则, 而阻抗效应和窒息效应不遵从回馈原则。不同效应产生的条件包括元刻板印象检索难度、元刻板印象个体化程度、个体内部资源、印象管理动机以及群体社会地位等。未来研究可在不同元刻板印象效应的适用范围及边界条件, 干预方法, 激活方式的比较等方面进行拓展。     

农民工刻板印象的自动化激活:来自IAT的证据

采用内隐联想测验的研究范式,探讨了被试对农民工群体内隐刻板印象的自动化激活。结果发现,被试对"农民工/消极词"的反应时要小于"农民工/积极词"的平均反应时。这一结果说明,在被试的认知图式中农民工群体和消极词之间的语义联系大于其和积极词之间的语义联系,即被试对农民工持消极的刻板印象,且这种消极的刻板印象会自动化地激活。     

情感一致性及其对认知加工的影响

具身情绪观认为情感的核心功能是评价,这种评价信息会同时表征在低层感知系统和高层认知系统中,它们相互影响、互为因果。情感一致性反映的是情感具身反应（心理感受、情感相关的身体动作和表情等）与情感认知评价（情感的观念性内容,积极与消极）在效价上的耦合关系。这种关系突出的表现为效价上是否一致,情感一致促进其后的认知加工,情感不一致的作用相反。该观点在短时记忆、叙事建构、刻板印象和说服效果等领域得到了证实。未来的研究应重视情感一致性的情感意义,扩展情感一致性定义及假设,并检验情感一致性的评价本质。     

印象形成中社会知觉信息效价冲突的认知控制效应

当个体信息与类别信息同时呈现时,个体的自我控制资源与信息效价产生交互作用,且共同影响他人印象形成的认知控制策略和信息加工深度。为进一步探究这一现象所产生的印象控制效应,采用自我控制资源损耗任务将96名被试随机分为高损耗组和低损耗组,并让他们完成内隐联想测验,以考察个体信息与类别信息的效价冲突时,他人印象控制策略如何受到自我控制资源与信息效价的双重影响。结果发现:(1)个体信息与类别信息的印象控制依赖于自我控制资源。(2)自我控制资源损耗与信息效价类型存在显著的交互作用。当个体损耗了较多的自我控制资源后,对效价冲突的个体信息与类别信息进行印象加工时,消极刻板印象的激活因受到这两类效价冲突信息的限制,只能依赖实时更新的面部表情信息,从而形成自下而上的反应性控制; 当个体损耗的自我控制资源较少时,对同样的个体信息与类别信息,不论效价相容或冲突,均能保持对消极刻板印象的自动激活,从而导致自上而下的主动性控制。     

消极元刻板印象激活对老年人认知表现的影响

本研究以59名老年人为研究对象,采用N-back认知任务探讨在不同难度的认知负荷任务中老年人消极元刻板印象激活的认知效应。结果发现：1、消极元刻板印象激活组的正确率显著低于未激活组;高认知负荷任务组的正确率显著低于低认知负荷任务组。2、消极元刻板印象激活组的反应时显著长于未激活组;高认知负荷任务组的反应时显著长于低认知负荷任务组;组别与任务难度之间交互作用达到边缘显著,在低认知负荷任务中,消极元刻板印象激活组和未激活组的反应时差异不显著,在高认知负荷任务中,消极元刻板印象激活组的反应时显著长于未激活组。上述结果表明,老年人消极元刻板印象的激活导致了负面的认知效应。     

Functional modularity in stereotype representation

We employed the retrieval-practice paradigm to test the hypothesis that stereotypes are organized in a meaningful, valence-based way that promotes evaluative coherence. Replicating previous research, we demonstrated that the rehearsal of traits known to describe a target person produced enhanced recall of those practiced traits and reduced recall of other known but non-practiced traits, relative to baseline. However, both the availability of a group label that united the traits within a stereotype and the evaluative consistency of the practiced and non-practiced traits moderated the nature of these effects: although recall of non-practiced stereotypic traits that were evaluatively inconsistent with the practiced traits showed the typical pattern of inhibition, recall of non-practiced stereotypic traits that were evaluatively consistent with the practiced traits was facilitated relative to baseline. We conclude by discussing how the modular representation implied by these findings is functional, potentially fostering the momentary experience of evaluative consistency in person perception.     

社会层级的内隐刻板印象：权力与地位的不同作用

采用探测词再认范式,考察社会层级的内隐刻板印象。结果发现,在能力推理上,无论地位高低,个体对高权力推理为积极的反应时显著长于消极,对低权力推理为消极的反应时显著长于积极;在热情推理上,无论权力高低,个体对高地位推理为积极的反应时显著长于消极,对低地位推理为消极的反应时显著长于积极。这表明,权力和地位在热情和能力维度的刻板印象中起着不同的作用,其中权力正向预测能力,地位正向预测热情。     

老年夫妻的老化刻板印象对死亡焦虑的行动者效应和对象效应

目的：考察老年人的老化刻板印象对自身及配偶的死亡焦虑的影响。方法：145对老年夫妻完成老化印象量表和死亡焦虑量表,并运用行动者-对象互依模型进行数据分析。结果：（1）老化刻板印象和死亡焦虑在夫妻内部分别具有一致性;（2）老化刻板印象对自身死亡焦虑的行动者效应显著;（3）丈夫的积极老化刻板印象对妻子死亡焦虑的对象效应显著,妻子的消极老化刻板印象对丈夫死亡焦虑的对象效应显著。结论：老年人的老化刻板印象不仅影响自身而且影响配偶的死亡焦虑,但夫妻之间的影响存在性别差异。     

How societal stereotypes might form and evolve via cumulative cultural evolution

The current article examines how societal stereotypes might form and evolve through a process of cumulative cultural evolution as social information is repeatedly passed from person to person. Social psychology research has done much to inform our understanding about the substantial influence stereotypes exert on us as individuals and on our society, yet comparatively little is known about how society's pools of stereotype knowledge form and how they evolve. Here, we review evidence that as social information is repeatedly passed from person to person, there is a continuous cycle of stereotype formation and evolution that is driven by constraints and biases in (a) observations of the social environment, (b) cognitive representations of the social environment, and (c) social transmissions of cognitive representations of the social environment. We suggest the reason stereotypes exist and persist is because they are perfectly adapted for human cognition and the reason they are perfectly adapted for human cognition is because they are the cumulative product of human cognition.     

不同职业认同水平教师对职业生活事件的社会认知加工特征

探讨不同职业认同水平教师在对职业生活事件的编码、再认和启动阶段是否具有不同的社会认知加工特点。采用Tversky的社会认知实验范式对高、低职业认同水平教师进行比较研究,结果发现：（1）高职业认同教师更多将正性条目编码为正性,更少将正性和中性条目编码为负性;高职业认同教师在正性和中性条目的编码正偏向上显著高于低职业认同教师;（2）高职业认同教师能够再认更多原有正性和中性条目,低职业认同教师将更多新加的中性和负性条目判断为阅读材料中的原有条目;（3）高职业认同教师的正性启动量和启动正偏向都显著高于低职业认同教师。结论：不同职业认同水平的教师对职业生活事件存在不同的社会认知加工特征,高职业认同教师的社会认知加工更积极有效。     

Pre-event stereotypes and misinformation effects in young children

This study examined the effects of pre-event stereotypes on 5-year-old children's memories for the visit of an adult male to their school. Children were read three stories in which this man was described in positive, negative, or neutral terms. Following the visit, children were read post-event narratives which contained positive and negative misinformation that was consistent and inconsistent with the pre-event stereotype. Children were then given a recognition test under inclusion and exclusion instructions. Negative misinformation was correctly rejected more often than positive misinformation. Children given a positive pre-event stereotype were more likely to accept positive misinformation than those in the other stereotype conditions. Process dissociation analyses revealed that recollection for negative misinformation was larger than for positive misinformation; the opposite was the case for familiarity.     

Different brain mechanisms between stereotype activation and application: evidence from an ERP study

Stereotyping involves two processes in which first, social stereotypes are activated (stereotype activation), and then, stereotypes are applied to given targets (stereotype application). Previous behavioral studies have suggested that these two processes are independent of each other and may have different mechanisms. As few psychophysiological studies have given an integrated account of these stages in stereotyping so far, this study utilized a trait categorization task in which event-related potentials (ERPs) were used to explore the brain mechanisms associated with the processes of stereotype activation and its application. The behavioral (reaction time) and electrophysiological data showed that stereotype activation and application were elicited respectively in an affective valence identification subtask and in a semantic content judgment subtask. The electrophysiological results indicated that the categorization processes involved in stereotype activation to quickly identify stereotypic and nonstereotypic information were quite different from those involved in the application. During the process of stereotype activation, a P2 and N2 effect was observed, indicating that stereotype activation might be facilitated by an early attentional bias. Also, a late positive potential (LPP) was elicited, suggesting that social expectancy violation might be involved. During the process of the stereotype application, electrophysiological data showed a P2 and P3 effect, indicating that stereotype application might be related to the rapid social knowledge identification in semantic representation and thus may be associated with an updating of existing stereotypic contents or a motivation to resolve the inconsistent information. This research strongly suggested that different mechanisms are involved in the stereotype activation and application processes.     

Stereotypes as justifications for prior intergroup discrimination: Studies of Scottish national stereotyping

Two studies provide support for the group‐justification approach to stereotyping (Tajfel, 1981 ; Huici, 1984 ). This approach contends that stereotypes not only serve cognitive functions for individuals but also provide a means of justifying prior intergroup discrimination. Study 1 investigated whether the content of the Scottish ingroup stereotype changes due to the prior expression of intergroup discrimination. Scottish students were primed with either a ‘differentiation’ or a ‘fairness’ ingroup norm and completed two intergroup judgement tasks. Other Scottish students were primed only with a ‘differentiation’ ingroup norm, while a control group received no prime or judgement tasks. Only participants who experienced the ‘differentiation’ ingroup norm prime and the intergroup judgement tasks changed the content of their ingroup stereotype as an attempt to justify their discriminatory behaviour. Study 2 examined whether Scottish students would use both positive ingroup and negative outgroup stereotypes to rationalize intergroup discrimination. Students who experienced a ‘differentiation’ ingroup norm prime and intergroup judgement tasks showed the highest level of superior recall for positive ingroup and negative outgroup stereotype‐consistent words compared to stereotype‐neutral words. This finding suggests that the expression of intergroup discrimination activates the use of both positive ingroup and negative outgroup stereotypes. Together the findings of these two studies provide empirical support for the notion that stereotypes serve social as well as cognitive functions. Copyright © 2001 John Wiley & Sons, Ltd.     

基于面孔知觉的刻板印象激活两阶段模型

从个体建构研究视角出发, 考察了基于面孔知觉的刻板印象激活过程。实验一比较了性别分类判断、启动范式以及同时呈现范式下刻板印象匹配性判断三者所用反应时的差异, 结果发现, 后者显著地大于前二者, 且等于前二者之和; 面孔倒置呈现使同时呈现范式下刻板印象匹配判断的反应时和错误率显著增大, 但其对启动范式中刻板印象匹配判断的反应时和错误率没有影响。实验二基于同时呈现范式, 通过不同程度的面孔变形来操纵性别类别提取的难度, 更精确地探讨了基于面孔知觉的社会类别信息提取过程对刻板印象激活的影响, 结果表明, 随着从面孔中提取类别信息难度的增加, 刻板印象激活所用的反应时也逐渐增大。研究结果证实了研究者所提出的刻板印象激活两阶段模型, 即基于面孔知觉的社会类别提取阶段和刻板印象信息激活阶段, 证实社会类别激活和刻板印象信息激活是两个分离的过程, 以社会类别信息提取为目的的面孔知觉对刻板印象的激活有显著影响。
