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。     

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。     

健全人对不同能力残疾人的刻板印象:基于SCM模型的研究

基于刻板印象内容模型(SCM),探讨了健全人对不同能力水平残疾人的刻板印象.其中,实验1基于对残疾人刻板印象内容量表的修订以及对能力发挥度不同的残疾人图片的筛选,考察了健全人对残疾人的外显刻板印象.实验2采用单类别内隐联想测验(SC-IAT)考察了健全人对残疾人的内隐刻板印象.结果发现:(1)在外显层面上,被试对高能力残疾人表现出高胜任且高热情的积极刻板印象,而对低能力残疾人表现出低胜任但高热情的混合刻板印象;(2)在内隐层面上,被试对高能力残疾人表现出高胜任且高热情的积极刻板印象,但对低能力残疾人表现出低胜任且低热情的消极刻板印象;(3)残疾人能力的有效发挥可显著改善被试对其胜任度和热情度的外显及内隐刻板印象.     

区域刻板印象的激活实验研究

该研究以甘肃人和内蒙古人为研究对象,采用不同加工任务来启动被试的刻板印象,探讨了甘肃人和内蒙古人的区域刻板印象以及区域刻板印象的启动方式,并与相关研究进行了比较。结果发现:区域刻板印象是普遍存在的,区域刻板印象的启动激活是自动的,不同加工方式对刻板印象的激活程度是不同的。     

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。     

错误记忆的产生是否依赖对词表的有意加工：无意识激活的证据

使用DRM范式考察了错误记忆产生过程中无意识激活的存在与否。通过操纵实验任务和呈现方式,导致被试对学习词表的无意加工和不同水平的有意加工。结果发现,无意加工时所产生的对关键诱饵的无意识激活足以导致错误记忆效应,说明对词表的有意加工并非错误记忆产生所必需。随着对词表有意加工水平的提高,多次无意识激活的累积可导致增强的错误记忆效应,且表现出与真实记忆的共变,而阻断连续激活累积的因素可有效降低错误记忆     

刻板印象提升与刻板印象促进

刻板印象提升指个体意识到外群体具有消极刻板印象, 而产生与受诋毁的外群体向下的社会比较, 以提高个体自我效能感和动机, 进而提高表现; 刻板印象促进是积极刻板印象被激活后的积极结果, 指当个体处在他们的积极刻板印象身份被激活的情境中, 表现上升的一种现象。在刻板印象提升与刻板印象促进概念论述的基础上, 重点探讨了调节变量和结果影响这两种联系, 并从相关概念、被试要求和心理机制这三方面论述了这两者的区别。最后, 指出未来研究应加强对二者的关注, 消除其在概念上的混淆, 开展相关心理与神经机制的研究, 以及结合刻板印象阻抗进行探讨。     

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。     

大学生职业性别刻板印象的内隐研究

本研究采用内隐联想测验（IAT）和刻板解释偏差（SEB）两种方法对大学生的职业性别刻板印象进行了内隐研究。发现被试整体在两次实验中均表现出极为显著的内隐刻板印象,女大学生头脑中的刻板印象对其行为归因已形成显著影响。研究结果表明,SEB是一种测量内隐刻板印象的有效方法。     

时间压力对错误记忆的影响:情绪的调节作用

考察时间压力下不同类型的情绪刺激和情绪状态对错误记忆的影响,并进一步探讨时间压力对心境一致性错误记忆的影响。实验1采用经典的DRM范式,记录被试对情绪关键诱饵的错误再认数。结果发现时间压力增强了被试对负性关键诱饵的错误再认。实验2先在测试阶段启动被试的情绪,再记录关键诱饵的错误再认数。结果发现,在时间压力下,正性情绪组的被试有更多的错误记忆。实验3采用带有情绪效价的DRM词表,并在测试阶段启动被试的正负情绪,然后再记录情绪关键诱饵的错误再认数。结果发现,压力组和控制组被试都表现出了明显的心境一致性错误记忆。研究结果表明,时间压力对错误记忆具有增强作用,尤其对负性心境一致性错误记忆具有更为明显的增强作用,但个体的负性情绪会削弱在时间压力下错误记忆的产生。这些结果进一步发展了激活监控理论和情感信息等价假设理论。     

大学生对穷人的消极刻板印象及猜测偏向

主要考察大学生对穷人的消极刻板印象及猜测偏向。实验1中的两个单类内隐联想测验结果与前人研究基本一致：虽然被试对穷人热情的评价相对积极,但总体上认为穷人低能力、低热情。实验2通过源监测任务发现,在忘记特质词来源的情况下,被试倾向于猜测消极特质词来自贫困者,积极特质词来自小康者。研究不仅证实了大学生对穷人的消极刻板印象,而且进一步发现大学生存在对穷人的消极猜测偏向。     

儿童的性别刻板印象威胁及其干预

刻板印象威胁即令污名群体的成员在消极刻板印象领域中表现下降的一种现象, 考察儿童性别刻板印象威胁能为从源头干预性别刻板印象威胁提供可能。基于此, 从儿童性别刻板印象威胁的产生(产生条件和产生时间)、操纵、影响(对女孩的影响和对男孩的影响)及干预(多重身份、沙文主义、积极榜样和反刻板印象)进行论述。未来研究可以从地域文化、研究对象、干预措施和研究领域等方面继续拓展。     

刻板印象与特质建构关系的实验研究

根据平行-约束-满足模型的基本主张,利用情境模拟法探讨了特质激活与刻板印象的建构关系以及刻板化信息与个体化信息经由特质激活所表现出的交互影响。实验结果表明：(1)刻板印象影响特质的含义,特质会自动化地激活刻板印象,并且由特质及其具体的描述性内容所形成的个体化信息在具体的情景中联合起来影响刻板印象效应;(2)刻板印象与其他信息在加工通路上是相对独立或平行的;(3)刻板印象是兼具自动化加工与控制加工的混合体。     

Alleviating women’s mathematics stereotype threat through salience of group achievements

Stereotype threat impairs performance in situations where a stereotype holds that one’s group will perform poorly. Two experiments investigated whether reminding women of other women’s achievements might alleviate women’s mathematics stereotype threat. In Experiment 1, college women performed significantly better on a difficult mathematics test when they were first told that women in general make better participants than men in psychology experiments. In Experiment 2, college women performed significantly better on a difficult mathematics test when they first read about four individual women who had succeeded in architecture, law, medicine, and invention. The results are seen as having implications for theories of stereotype threat, self-evaluation, and performance expectations.     

Stereotype threat and working memory: mechanisms, alleviation, and spillover

Stereotype threat (ST) occurs when the awareness of a negative stereotype about a social group in a particular domain produces suboptimal performance by members of that group. Although ST has been repeatedly demonstrated, far less is known about how its effects are realized. Using mathematical problem solving as a test bed, the authors demonstrate in 5 experiments that ST harms math problems that rely heavily on working memory resources--especially phonological aspects of this system. Moreover, by capitalizing on an understanding of the cognitive mechanisms by which ST exerts its impact, the authors show (a) how ST can be alleviated (e.g., by heavily practicing once-susceptible math problems such that they are retrieved directly from long-term memory rather than computed via a working-memory-intensive algorithm) and (b) when it will spill over onto subsequent tasks unrelated to the stereotype in question but dependent on the same cognitive resources that stereotype threat also uses. The current work extends the knowledge of the causal mechanisms of stereotype threat and demonstrates how its effects can be attenuated and propagated.     

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.     

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 and inflexible perseverance in problem solving

The present research examines whether women burdened by stereotype threat, a threat of confirming negative ingroup stereotypes (Steele, C. M., & Aronson, J. (1995). Stereotype threat and the intellectual test performance of African Americans. Journal of Personality and Social Psychology, 69(5), 797-811), are less able to abandon old strategies and employ newer, more efficient ones when conditions change. In two studies, stereotype threat was found to increase inflexible perseverance: women made to believe they were taking a diagnostic math/spatial ability test, compared to those not threatened by stereotypes, were more likely to use previously successful but presently inefficient or incorrect strategies. In Study 1, participants under stereotype threat also suppressed relevant stereotypes to the greatest degree, and their inflexible perseverance was predicted by the degree to which they suppressed these stereotypes. Implications for test performance and potential decision-making effects of stereotype threat are discussed.     

Accuracy,Consensus, In-Group Bias,and Cultural Frame Shifting in the Context of National Character Stereotypes

We examined Finns’ and bilingual Swedish-Finns’ stereotypes regarding personality differences between Finns and Swedish-Finns and compared them with their respective self-ratings. Stereotype ratings by both groups converged on depicting Swedish-Finns as having a more desirable personality. In-group bias also influenced stereotypes. Contrary to predictions based on the Stereotype Content Model, out-group stereotypes were not compensatory. Consistent with the kernel of truth hypothesis of national stereotypes, Swedish-Finns’ aggregate self-ratings resembled their stereotype of personality differences between the two groups, and their personality self-ratings were more desirable than Finns’ self-ratings. Tentatively suggesting the occurrence of cultural frame shifting, the resemblance between Swedish-Finns’ self-ratings and their stereotype of Swedish-Finns was, although only marginally statistically significantly, somewhat stronger when the self-ratings were provided in Swedish.
