积极总是好的吗？积极元刻板印象对工作记忆的影响及其机制

以往关于元刻板印象的研究集中于消极视角,而对积极元刻板印象如何影响认知加工缺乏相应探讨。本研究采用N-back任务,选取农村大学生为被试,通过3个实验考察积极元刻板印象激活对工作记忆的影响及其机制。结果表明,在工作记忆高难度任务(2-back)中,积极元刻板印象激活会导致更低的正确率,趋近动机在其中起中介作用,核心自我评价起调节作用,即积极元刻板印象激活会通过增加趋近动机,降低高难度任务的正确率,且这一效应仅存在于高核心自我评价者中。本研究将积极元刻板印象窒息效应拓展到认知加工领域,并且揭示了窒息效应的内在机制。     

随迁儿童元刻板印象威胁对工作记忆的影响:群际焦虑的中介作用

元刻板印象是指个体关于外群体成员对其所属群体所持刻板印象的信念或看法,消极元刻板印象的激活会导致群体成员的一种社会心理困境和认知不平衡状态,诱发压力和害怕体验,并损害其行为表现。研究采用工作记忆的N-back范式,对随迁儿童的元刻板印象威胁效应进行探讨。实验通过让被试根据不同指导语写形容词的方式,操纵了"威胁"和"无威胁"的条件,并考察不同条件对群际焦虑和工作记忆的影响。结果如下:(1)威胁组被试的群际焦虑水平显著高于无威胁组;(2)在工作记忆的3个任务难度中,威胁组被试的正确率显著低于无威胁组;随着难度的增加,威胁组和无威胁组被试的正确率都显著下降;(3)在工作记忆的3个任务难度中,威胁组被试的反应时显著长于无威胁组;随着难度的增加,威胁组和无威胁组被试的反应时都显著增长,且组别与任务难度的交互作用显著;(4)群际焦虑在元刻板印象与工作记忆任务的正确率(中等难度任务)间起完全中介作用,在元刻板印象与工作记忆任务的反应时(中等难度任务)间起部分中介作用。结果表明,在激活随迁儿童的消极元刻板印象后,产生了明显的元刻板印象威胁效应。     

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。     

数学-性别刻板印象对女生的威胁效应:场认知风格的调节作用

旨在检验数学-性别刻板印象是否对我国高中女生产生威胁效应,并探讨场认知风格在数学-性别刻板印象威胁效应中是否存在调节作用。研究发现,女生在激活数学-性别刻板印象情境下的工作记忆容量显著低于在非激活情境下的工作记忆容量;认知风格和测验情境之间交互效应显著,场依存个体激活情境下的工作记忆容量显著低于非激活情境下的,场独立个体两种情境下相差不显著。说明数学-性别刻板印象给女生带来了威胁;认知风格调节着数学-性别刻板印象威胁效应的强弱,场依存个体受到的威胁很大,场独立个体几乎不受威胁。

贫困大学生元刻板印象威胁对群际关系的影响:群际焦虑的中介和自尊的调节作用

元刻板印象威胁是指消极元刻板印象所导致的群体成员的一种社会心理困境和认知不平衡状态,会诱发压力和害怕体验,进而损害其行为表现。基于群际焦虑模型,本研究拟考查元刻板印象、群际焦虑、自尊等因素对群际关系的影响,具体为贫困大学生消极元刻板印象对群际关系的影响及群际焦虑的中介作用、自尊的调节作用。研究以江苏省徐州市某高校的158名贫困大学生为被试,通过操控指导语的方式将其随机分为威胁组（消极元刻板印象激活组）和无威胁组（元刻板印象未激活组）。结果如下：（1）威胁组被试的群际焦虑水平显著高于无威胁组,群际关系水平显著低于无威胁组;（2）群际焦虑在元刻板印象威胁与群际关系间起中介作用,自尊在前半路径（元刻板印象和群际焦虑间）和后半路径（群际焦虑与群际关系间）均起调节作用。结论：激活贫困大学生消极元刻板印象会对群际关系产生威胁效应。     

网络学习中学习者个人特征对学习投入的影响:一个有调节的中介效应模型

以参与网络课堂的387名大学生为被试,考察自我效能感、内隐智力信念和动机调节等学习者特征对网络学习环境中学习投入的影响及其作用机制。结果表明:(1)网络学习者的自我效能感、动机调节、内隐智力信念均能正向预测学习投入;(2)动机调节在自我效能感和学习投入的关系中起部分中介作用;(3)"自我效能感→动机调节→学习投入"这一中介效应的后半路径受到学习者内隐智力信念的调节。相较于智力实体论者,动机调节的中介效应在智力增长论者中更强。     

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。     

情绪调节对消极元刻板印象激活的认知效应的影响

以101名中职生为被试,采用不同难度的工作记忆任务,探讨认知重评与表达抑制两种情绪调节策略对消极元刻板印象激活的认知效应的影响。结果发现:(1)情绪调节策略对元刻板印象激活的认知效应具有影响,且与认知任务的难度有关;(2)在低难度工作记忆任务中,情绪调节策略对元刻板印象激活的认知效应没有影响,在中等难度任务中,认知重评减弱了激活的认知效应,但表达抑制没有影响,在高难度任务中,认知重评没有影响,表达抑制反而增强了激活的认知效应。总之,不同情绪调节策略会对消极元刻板印象激活的认知效应产生不同的作用。     

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。     

An investigation of the link between attributional judgments and stereotype‐based judgments

Three experiments investigated the relationship between the attributions made for stereotype‐relevant behavior and stereotype‐based judgments. In Experiment 1 participants were presented with a short scenario describing a single stereotypic behavior and were given either a situational or a dispositional explanation for the behavior, before evaluating both the target and the group as a whole on stereotype‐based dimensions. As predicted, participants given a situational explanation for the stereotypic behavior described in the target and the group in less stereotype‐based terms than did baseline participants. In Experiment 2 and 3 participants were presented with a short scenario describing either a single stereotypic or counter‐stereotypic behavior but were asked to provide an explanation for the behavior, rather than being given one. As predicted, stereotypic behavior was attributed more strongly to dispositional than situational factors and counter‐stereotypic behavior more strongly to situational than dispositional factors. No overall moderation of group‐based beliefs relative to baseline was seen in either experiment. Correlations between the attributions and stereotypic‐based judgments did, however, show a relationship between the strength of the attributions made for the behaviors and stereotype‐based judgements. Implications for the moderation of stereotype‐based judgments are discussed. Copyright © 2000 John Wiley & Sons, Ltd.     

Priming of disability and elderly stereotype in motor performance: similar or specific effects?

In three experimental studies, the effects of priming participants with the disability stereotype were investigated with respect to their subsequent motor performance. Also explored were effects of activating two similar stereotypes, persons with a disability and elderly people. In Study 1, participants were primed with the disability stereotype versus with a neutral prime, and then asked to perform on a motor coordination task. In Studies 2 and 3, a third condition was introduced: priming participants with the elderly stereotype. Results indicated that priming participants with the disability stereotype altered their motor performance: they showed decreased manual dexterity and performed slower than the non-primed participants. Priming with the elderly stereotype decreased only performance speed. These findings underline that prime-to-behavior effects may depend on activation of specific stereotype content.     

The difference isn't black and white: stereotype threat and the race gap on Raven's Advanced Progressive Matrices

This study addresses recent criticisms aimed at the interpretation of stereotype threat research and methodological weaknesses of previous studies that have examined race differences on Raven's Advanced Progressive Matrices (APM). African American and White undergraduates completed the APM under three conditions. In two threat conditions, participants received either standard APM instructions (standard threat) or were told that the APM was an IQ test (high threat). In a low threat condition, participants were told that the APM was a set of puzzles and that the researchers wanted their opinions of them. Results supported the stereotype threat interpretation of race differences in cognitive ability test scores. Although African American participants underperformed Whites under both standard and high threat instructions, they performed just as well as Whites did under low threat instructions.     

Stereotype Threat and Employment Testing: A Commentary

This article comments on Sackett, Schmitt, Ellingson, and Kabin's (2001) suggestion that stereotype threat may not generalize to employment testing, and the 4 articles of this issue following from it. We argue that each experiment lacked the no-stereotype threat control group needed to experimentally test stereotype threat effects; that sizeable stereotype threat effects occurred nonetheless; and that research not reviewed by Sackett et al. suggests that stereotype threat may be the sole cause of important real-life test-score gaps. The 4 experiments, we suggest, reveal important mediators of stereotype threat effects; their test-specific and general form, and their generalizability to IQ testing. We offer a framework for assessing its generalizability to real-life employment tests.     

Deflecting negative self-relevant stereotype activation: The effects of individuation

Under stereotype threat, when an individual risks confirming a negative self-relevant stereotype, activation of the stereotype can inhibit performance on a subsequent, related task. Although a significant amount of research has been devoted to examining the effects of stereotype activation on performance, relatively little is known about successful methods of intervention. Two experiments tested the hypothesis that individuation prior to performance would eliminate impairment due to stereotype activation. In both studies, Caucasian female participants in either a gender-prime or no-prime condition were administered a mathematics test. Gender primed, individuated participants outperformed gender primed, non-individuated participants and performed as well as unprimed, non-individuated (i.e., control) participants, supporting individuation as a protective measure against the detrimental effects of negative stereotype activation.     

Arousal and stereotype threat

Seemingly insignificant features of the context can undermine the quantitative performance of skilled females—an effect attributed to stereotype threat. The present studies tested the hypotheses that stereotype threat triggers arousal, and that attributions about that arousal could moderate the effects of stereotype threat on performance. To examine whether arousal is triggered by stereotype threat, we conducted two experiments in which female participants were asked to take a math test under conditions of stereotype threat or not. In Study 1, women under stereotype threat performed better on an easy threat-irrelevant task, but worse on a difficult threat-irrelevant task than women not under threat. In Study 2, threatened women underperformed on a math test, but this underperformance was attenuated for women directed to misattribute their arousal. These results suggest that arousal—and how arousal is attributed—may play an important role in the debilitating effects of stereotype threat.     

The benefits of emotional expression for math performance

This study investigated the effects of emotional expression on actual and perceived math performance. Female participants were either asked to express their emotions or given no special instructions before taking a math test under stereotype threat or no stereotype threat conditions. Participants in the emotional expression condition performed better on the math test than participants in the control condition. Under stereotype threat, participants in the emotional expression condition believed they performed better on the math test. Emotional expression appears not only to have health benefits (e.g., Pennebaker, 1997), but academic benefits as well, including for stereotyped threatened individuals.

Stereotype Threat Effects on the Raven Advanced Progressive Matrices Scores of African Americans1

The present experiment examined stereotype threat effects on the Raven Advanced Progressive Matrices (Raven) scores of African Americans. Support was found for Hypothesis 1, which stated that African Americans would experience significantly greater stereotype threat than Whites during an IQ testing situation. Hypothesis 2 proposed that a significant Race x Test Diagnosticity Condition interaction would occur in which the mean difference in intelligence test scores between African Americans and Whites (favoring the latter group) would be largest when the test was framed as a measure of intelligence, and smaller when framed as nonindicative of intelligence. Limited support for Hypothesis 2 was found in that a marginally significant Race x Test Diagnosticity Condition interaction was obtained. However, the interaction failed to reach conventional levels of statistical significance. Although preliminary, the present findings provide some support for the notion that stereotype threat compromises the intelligence test performance of African Americans.
