印象形成中交叉刻板印象的加工机制

以大学生作为被试,旨在探究：在交叉刻板印象加工过程中,是否存在某一单维刻板印象的加工优势效应？如果存在,靶子熟悉度的差异是否会影响单维刻板印象的加工优势效应？该单维刻板印象加工优势效应是否还会受到其他单维刻板印象加工的调节。研究结果表明：（1）在对具有性别-年龄组合而成的交叉刻板印象的人群进行判断时,通过面孔进行启动,发现在不同的条件下分别存在性别单维刻板印象和年龄单维刻板印象的加工优势效应,即年轻男性或女性面孔的性别特征较年龄特征更容易得到加工和提取,老年男性或女性面孔的年龄特征较性别特征更具有加工优势。而在范畴词汇启动下,老年男性或女性词汇启动下的年龄特征较性别特征更具有加工优势。（2）熟悉性会影响单维刻板印象的加工优势,即在年轻被试感知面孔或范畴词汇时,其对老年男性或女性靶子间击中率的差异要显著大于对年轻男性或女性的靶子间击中率的差异。换言之,年轻被试感知老年人靶子的性别与年龄间的差异要显著大于年轻人靶子,出现自我参照现象。（3）在交叉刻板印象加工中,同时存在的各类单维刻板印象加工是彼此削弱的,具有优势加工效应的刻板印象的加工会受到非优势刻板印象加工的抑制。（4）在交叉刻板印象加工中,优势刻板印象加工会受到其相对刻板印象加工的削弱。     

刻板印象激活的无意图性及其大脑神经活动特征

采用启动Stroop范式, 对刻板印象激活的无意图性及其大脑神经活动特征进行了探讨。操纵了启动和“无启动”条件以及与启动所激活的刻板印象一致、冲突和无关的3类靶子词, 记录了36名大学生被试对靶子词进行颜色判别的行为反应和脑电图(EEG, electroencephalogram)。结果发现：(1)“无启动”条件下对3类靶子的反应时基本一致; 启动条件下对一致靶子做出颜色判别的反应时显著快于对冲突靶子的, 对无关靶子的反应时介于两者之间。(2)“无启动”条件下无关靶子诱发的N400波幅最大--显著大于一致和冲突靶子诱发的, 后两者诱发的N400无差异; 启动条件下一致靶子诱发的N400波幅显著小于冲突和无关靶子诱发的N400波幅, 无关靶子诱发的N400波幅也小于冲突靶子诱发的N400波幅。这表明刻板印象激活是一个发生在知觉后加工阶段的具有无意图性的自动化加工过程, 刻板印象激活效应具有抑制冲突信息加工同时促进一致信息加工的“双刃剑”模式, N400可以作为考察这一认知过程特征的电生理学指标。     

老年刻板印象威胁及其研究操纵

随着人口老龄化的不断加剧, 老年刻板印象威胁受到越来越多的关注。不同于种族或民族、性别等刻板印象威胁, 老年刻板印象威胁表现出累积性、共通性与连续性等特征。目前关于老年刻板印象威胁的研究多集中于认知老化尤其是记忆老化上, 关注老年刻板印象威胁对老年司机和老年员工的消极影响。消除与降低老年刻板印象威胁的消极效应可以从认知改变、群体认同、代际接触、老龄自我实现和个性化以及媒体宣传等五个方面来进行。在实验室研究中, 老年刻板印象威胁有外显与内隐两种不同的操纵形式。未来可以从扩展研究领域、细化“年龄”差异、比较整体效应大小和性别差异、侧重积极效应以及加强本土化检验和跨文化比较研究等方面来深化。     

Reducing Stereotyping Through Mindfulness: Effects on Automatic Stereotype-Activated Behaviors

We assessed whether mindfulness (active categorization) can prevent automatic stereotype-activated behaviors related to the elderly. Eighty participants (mean age = 24.4) were given a set of photographs to prime the dimension Old Age and were asked to categorize them multiple times, to see whether the effect of the prime could be reduced through increased mindfulness. Participants were randomly assigned to one of four conditions, where they were asked to categorize the photographs across (1) four self-generated categories; (2) four assigned categories; (3) a single category—Gender; or (4) a single category—Age. Participants’ walking speed (cf. Bargh et al. 1996, Experiment 2) was then measured, as they moved between the two experimental stations. The results show that greater mindfulness predicted greater walking speed, indicating a decrease in the effect of the automatic stereotype-activated behavior.

Issues Involving Informed Consent for Research Participants with Alzheimer’s Disease

Alzheimer’s disease is the most common form of dementia which is estimated to impact 350,000 people over 65 years of age in Canada. The lack of effective treatment and the growing number of people who are expected to be diagnosed with Alzheimer’s disease in the near future are compelling reasons why continued research is in this area is necessary. With additional research, there needs to be greater recognition of the complexity of seeking ongoing informed consent from those with Alzheimer’s disease. This complexity is because the impairment of memory and cognitive ability does not diminish in a linear manner, but rather fluctuates between periods of impairment and relatively normal cognitive lucidness. There is limited discussion in the guidelines of those progressing from early stages of Alzheimer’s disease who have intermittent cognitive function. Guidelines to research and Research Ethics Boards require further development to facilitate researcher including those with Alzheimer’s disease while protecting this growing pool of potential participants.     

想象对大学生内隐刻板印象的影响研究

通过对大学生在三种想象条件下性别-职业刻板印象的IAT的结果的对比进行实验。研究表明:反刻板印象想象策略的干预效果明显,刻板印象的内隐效应在明显地减弱;即使是大学生,在性别-职业刻板印象上也存在内隐效应,而且没有性别差异;内隐刻板印象具有一定的适应性,在内隐的和无意识的水平上反刻板印象想象无法完全消除刻板印象。     

The Elusive Nature of Executive Functions: A Review of our Current Understanding

Executive functions include abilities of goal formation, planning, carrying out goal-directed plans, and effective performance. This article aims at reviewing some of the current knowledge surrounding executive functioning and presenting the contrasting views regarding this concept. The neural substrates of the executive system are examined as well as the evolution of executive functioning, from development to decline. There is clear evidence of the vulnerability of executive functions to the effects of age over lifespan. The first executive function to emerge in children is the ability to inhibit overlearned behavior and the last to appear is verbal fluency. Inhibition of irrelevant information seems to decline earlier than set shifting and verbal fluency during senescence. The sequential progression and decline of these functions has been paralleled with the anatomical changes of the frontal lobe and its connections with other brain areas. Generalization of the results presented here are limited due to methodological differences across studies. Analysis of these differences is presented and suggestions for future research are offered.     

Stereotype internalization and women’s math performance: The role of interference in working memory

It has long been argued that stigmatized individuals can ultimately internalize the stereotype alleging their inferiority. The present article investigated whether the internalization of the reputation of math inferiority that targets women can affect their math performance and whether this influence is caused by a disruption of working memory. A first study showed that stereotype endorsement had a significant impact on women’s statistic performance by lowering their self-evaluation of math ability even when controlling for prior achievement. A second study was designed to assess the possibility that the lower math performance displayed by women with low self-evaluation of math ability was due to interference in working memory. Using a dual task paradigm, this study showed that indeed women with low math self-evaluation displayed more errors and spent more time solving additions than women with high math self-evaluation, but mainly on difficult items of the dual task. The findings, which are congruent with an explanation in terms of a temporary disruption of working memory, are discussed.     

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。     

双性化大学生人格特征研究

通过对北京市某所大学826名大学生的调查,探讨性别、性别角色类型和新性别角色类型对大学生人格特征的影响。结果表明：1）双性化性别角色类型大学生约占1／4;2）用贝姆的分类方法,双性化大学生在开放性、宜人性、责任感、和谐性、人情、灵活性人格特征上均高于其他性别角色类型的大学生,可见,双性化性别角色大学生具有较积极的人格特征。按照Brenda Mae Woodhill和CurtisA．Samuels的分类方法,在外向性、开放性、宜人性、责任感、和谐性人格特征上,正性双性化性别角色类型的大学生均高于负性双性化大学生和其他性别角色类型的大学生。
