通过实验探讨了刻板印象的意识性抑制问题。被试为西北师范大学一年级本科生24人。结果表明：(1)性别刻板印象会影响对职业这种社会范畴的判断;(2）刻板印象效应比较顽固,较难受到意识性的抑制;（3）与刻板印象相反的个体化信息会削弱刻板印象效应;(4）刻板印象与个体化信息的加工很可能是平行的。     

高中生文理分科刻板印象的实验研究

采用2×4×2的重复测量的实验设计,探讨了性别是否会引起对于文理分科期望的刻板化加工以及刻板印象的意识性抑制问题,同时验证目前占主导地位的对范畴信息信任的减弱会增强对个体化信息的信赖这一假说。结果表明:(1)性别刻板印象会影响对文理科这种社会范畴的判断;(2)刻板印象比较顽固,较难受到意识性的抑制;(3)与刻板化信息完全相反的个体化信息的作用大于刻板化信息的作用,对刻板化信息的作用产生了一定的抑制,但无法完全抑制;(4)刻板印象与个体化信息的加工通路是平行的,同时它们彼此之间也是相互联系和限制的。     

认知资源和信息类型对大学生职业印象形成的影响

采用加工分离程序,探讨了认知资源和信息类型对大学生职业印象形成的影响及其心理加工机制。结果表明：(1)印象形成受到包括认知资源的限制、刻板化信息和个体化信息的典型性等多种因素的影响。刻板化信息间接地对印象形成起作用。个体化信息的作用远大于认知资源。(2)在印象形成过程中,控制性加工和自动化加工是并行的。(3)刻板化信息以内隐的自动化加工为主,个体化信息加工则存在外显与内隐两种方式。     

刻板印象的激活效应:行为和ERPs证据

以刻板印象表征中的核心内容——刻板特质词作为研究材料,采用分类-确认范式对刻板印象激活效应的时间进程及其认知机制进行了探讨。以性别范畴词"男"/"女"作为启动刺激,以性别刻板特质词作为靶子,特质词与范畴词构成一致和冲突两种情境,记录了34名被试(男女各半)对特质词与范畴词进行一致性判断时的行为反应和ERPs。结果发现:(1)刻板印象冲突情境下,因刻板印象激活效应的作用,被试的反应时要比刻板印象一致情境下更长;不同性别的被试均表现出性别内群体范畴词激活优势效应,即内群体范畴词启动条件下反应时更短。(2)刻板印象激活效应对早期ERP成分(P1、N170、N100、P2)没有影响,在刻板印象冲突情境下诱发了额-中区更显著的N400,该成分标志着刻板印象的激活效应;不同性别的被试均在内群体范畴词启动下诱发了波幅更大的P600。(3)刻板印象的激活效应以及内群体范畴词激活优势效应均发生在知觉后阶段。     

广告中性别刻板印象的信息加工方式

通过操纵注意方式、刻板印象的启动方式及被试的刻板化状态,探讨了广告中性别刻板印象信息加工的方式和特点。结果表明：（1） 广告中性别刻板印象信息的加工是自动化加工和控制性加工共同作用的结果,刻板化启动引起更多的自动化加工,反刻板化启动引起更多的控制性加工;（2）注意方式影响广告中性别刻板印象信息的控制性加工而不影响其自动化加工,集中注意时控制性加工的贡献最大;（3）对于广告中的性别刻板化信息,刻板化程度高的人具有更严格的判断标准。     

社会信息归类过程中刻板印象的内隐效应

采用信号检测论和间接测量方法探讨社会信息归类过程中的刻板印象内隐效应。实验结果表明 :⑴范畴启动可以自动激活有关的刻板印象内容 ,说明在很大程度上刻板印象是归类过程的一种必然结果与产物 ;⑵那些在内容上与范畴启动所导致自动的刻板印象激活及其相关内容一致、不一致或相反的建构分别易于出现同化与对比效应 ;⑶在个体水平上 ,通过意识性抑制在短期内很难压制刻板印象的自动激活 ,这表明刻板印象加工在很大程度上涉及到内隐过程     

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。     

外显与内隐刻板印象的分布式表征及其激活过程——基于认知神经科学视角的探索

刻板印象是人们有关群体的行为特征与特质属性信念化的认识, 它多以语义图式形式存储于长时记忆中。依据激活过程中意识参与程度的不同, 刻板印象具有内隐和外显两种表现型。不同于双加工理论“自动激活+认知控制”的研究视角, 本项目计划从内隐/外显记忆的多重记忆系统模型出发, 试图检验内隐与外显刻板印象在表征机制和激活过程上的差异。现有的多重记忆系统模型虽能解释内隐和外显刻板印象在记忆存储与提取上的机制差别, 但却无法阐释二者语义表征带有的心理理论特性以及二者的认知控制过程。有鉴于此, 本项目拟吸收“镜像系统−心理化系统”模型和双加工理论各自在特质与信念加工以及刻板印象认知控制上的理论优势, 深入探索内隐和外显刻板印象的分布式表征机制。借助ERP技术的时间过程优势和fMRI技术的脑区动态因果建模优势, 研究结果将最终揭示刻板印象分布式语义表征的动态加工机制。     

刻板印象的内隐效应与内一外群体效应的实验研究

采用间接测量方法分别探讨刻板印象的内隐效应与内一外群体效应。实验结果表明 :( 1)内隐刻板印象是存在的 ,并且在很大程度上是一种无意识内隐影响的表现 ;( 2 )刻板印象是一个自动化的过程 ;( 3)刻板印象表现出强烈的“内一外群体效应”     

无偏见动机对刻板印象和偏见激活的抑制作用:基于四分模型的分析

利用四分模型分解内隐联想测验的认知加工过程,考察无偏见动机对刻板印象和偏见自动激活的抑制作用。结果表明:(1)高低无偏见动机被试均了解社会文化对男同性恋的刻板印象;(2)高无偏见动机者没有产生"男同性恋-女性化"的刻板印象激活和"男同性恋-坏的"偏见激活,低无偏见动机者则有二者的激活。因此无偏见动机能够有效抑制刻板印象和偏见的自动激活,基于研究发现提出了刻板印象和偏见的发展模型。     

Stereotype threat,test anxiety,and mathematics performance

We investigated the combined effects of stereotype threat and trait test anxiety on mathematics test performance. Stereotype threat and test anxiety interacted with each other in affecting performance. Trait test anxiety predicted performance only in a diagnostic condition that prevented stereotype threat by stereotype denial. A state measure of fear of the test mediated this influence. However, stereotype threat reduced the performance of low test-anxious participants to the level of high test-anxious participants. Thus, stereotype threat affected persons low in test anxiety but not persons high in test anxiety. Both phenomena apparently share common mechanisms through which they impair performance.     

刻板印象威胁效应研究回顾与展望

刻板印象威胁是个体经历的一种风险,处于该风险中的个体担心自己会验证所属群体的消极刻板印象。刻板印象威胁会导致个体行为上的表现下降和心理上的分离与不认同。同时,刻板印象威胁效应也会受领域认同、群体认同和自我等因素的影响。心理机制方面,已由焦虑、唤醒等单一机制研究转向了多威胁线索加工模型、综合过程模型的探讨。研究发现,刻板印象威胁可以采用重塑任务与建立认同安全环境等手段进行应对。未来研究将集中于心理后果的研究、不同类型威胁的后继研究、现场研究及本土化研究。

源检测框架下,在记忆的提取阶段激活刻板印象会导致错误记忆,通过激活贫富刻板印象,考察对源检测记忆的影响,结果发现被试表现出刻板印象一致的错误记忆,通过多项式加工树模型的分析发现,被试在来源判断时利用刻板印象知识表现出猜测反应.     

老化刻板印象研究现状及展望

老化刻板印象是人们对老年人所持有的观念与预期,它能显著影响老化刻板印象持有者的生理功能、认知功能和行为结果。现有研究主要集中在老化刻板印象的机制、影响因素和中介变量方面。研究发现,老化刻板印象是通过内化形成的,刻板印象威胁理论和自我刻板化是解释老化刻板印象的两种作用机制。认知加工过程中的抑制能力、情境和文化差异是影响老化刻板印象的主要因素,而老化自我知觉和刻板期望则是老化刻板印象影响效果变量的中介因素。未来研究除了要继续探讨意识水平、情境因素、个体特征对老化刻板印象的影响以及老化刻板印象对不同年龄群体影响的特点以外,还应关注中介和干预研究,并进一步加强跨文化研究。     

STEREOTYPE THREAT AND GENDER DIFFERENCES IN PERFORMANCE ON A NOVEL VISUOSPATIAL TASK

Stereotype threat research has shown that being a member of a negatively stereotyped group may result in impaired performance on tests of skills thought to be relevant to the stereotype. This study investigated whether stereotype threat influences gender differences in performance on a novel test of visuospatial ability. Undergraduates ( N  = 194) were told that men outperform women on the test (explicit threat), were given no gender-relevant information (implicit threat), or were told that men and women do not differ (nullified stereotype). Although men outperformed women in the explicit and implicit stereotype threat groups, women's performance did not differ significantly from men's when told there is no gender difference. The effect was most pronounced for difficult line judgments. Although stereotypes regarding visuospatial ability may be less culturally salient than those of other cognitive abilities, these findings suggest that they influence performance nonetheless. Implications for optimizing cognitive test performance are discussed.     

Stereotype threat can reduce older adults' memory errors

Stereotype threat often incurs the cost of reducing the amount of information that older adults accurately recall. In the current research, we tested whether stereotype threat can also benefit memory. According to the regulatory focus account of stereotype threat, threat induces a prevention focus in which people become concerned with avoiding errors of commission and are sensitive to the presence or absence of losses within their environment. Because of this, we predicted that stereotype threat might reduce older adults' memory errors. Results were consistent with this prediction. Older adults under stereotype threat had lower intrusion rates during free-recall tests (Experiments 1 and 2). They also reduced their false alarms and adopted more conservative response criteria during a recognition test (Experiment 2). Thus, stereotype threat can decrease older adults' false memories, albeit at the cost of fewer veridical memories, as well.     

Forgetting by remembering: Stereotype inhibition through rehearsal of alternative aspects of identity

We applied previous research on retrieval-induced forgetting to the issue of stereotype inhibition. All participants learned about a target person who belonged to a stereotyped group, and then practiced retrieving a subset of the target’s characteristics. When participants practiced individuating information about the target, they showed inhibited memory for the target’s stereotypic traits. When participants practiced stereotypic information about the target, they showed inhibited memory for: (a) traits associated with another stereotyped aspect of the target’s identity; (b) individuating traits of the target; and (c) other, unpracticed traits of the target associated with the same stereotype. Stereotype belief moderated these inhibition effects; the more strongly participants believed in the stereotype, the less inhibition of stereotype-relevant traits they showed.     

When stereotypes get in the way: stereotypes obstruct stereotype-inconsistent trait inferences

There is a growing body of evidence indicating that people spontaneously make trait inferences while observing the behavior of others. The present article reports a series of 5 experiments that examined the influence of stereotypes on the spontaneous inference of traits. Results consistently showed weaker spontaneous trait inferences for stereotype-inconsistent behavioral information than for stereotype-consistent and stereotype-neutral information. Taken together, the current results suggest that specific spontaneous trait inferences become obstructed by inhibitory processes when behavior is inconsistent with an already activated stereotype. These findings are discussed in relation to stereotype maintenance processes and recent models of attribution in social judgment.     

The consequences of chronic stereotype threat: Domain disidentification and abandonment

Stereotype threat impairs performance across many domains. Despite a wealth of research, the long-term consequences of chronic stereotype threat have received little empirical attention. Beyond the immediate impact on performance, the experience of chronic stereotype threat is hypothesized to lead to domain disidentification and eventual domain abandonment. Stereotype threat is 1 explanation why African Americans and Hispanic/Latino(a)s "leak" from each juncture of the academic scientific pipeline in disproportionately greater numbers than their White and Asian counterparts. Using structural equation modeling, we tested the stereotype threat-disidentification hypothesis across 3 academic years with a national longitudinal panel of undergraduate minority science students. Experience of stereotype threat was associated with scientific disidentification, which in turn predicted a significant decline in the intention to pursue a scientific career. Race/ethnicity moderated this effect, whereby the effect was evident for Hispanic/Latino(a) students but not for all African American students. We discuss findings in terms of understanding chronic stereotype threat. (PsycINFO Database Record (c) 2012 APA, all rights reserved).
