建构主义教学与元思维的关系:认知压力的解释

本研究采用建构主义教学评估问卷、认知压力问卷、一般元思维量表与情境元思维量表对381名学生进行测量,考察了建构主义教学与元思维之间的关系,以及一级、二级认知压力在其中的中介或解释作用。研究采用结构方程模型分析,结果显示:(1)仅考虑一级认知压力时,建构主义教学能正向预测两种元思维,一级认知压力在建构主义教学与两种元思维间皆起部分中介作用;(2)仅考虑二级认知压力时,其在建构主义教学与两种元思维间皆起完全中介作用;(3)同时加入两种认知压力时,仅二级认知压力的中介作用显著。     

优差生亲子沟通与认知和情绪压力的关系

研究对优生、差生与其父母围绕数学问题解决而展开的沟通过程进行观察,并采用量表法测量其感受到的认知和情绪压力,以考察两变量之间的关系及优、差生在两者得分上的差异。结果发现：（1）优生无论在沟通行为次数上,还是在沟通行为类型上都表现出一些积极特征;（2）优生的二级认知压力显著高于差生,一级认知压力和情绪压力显著低于差生;（3）督促、指责等消极沟通行为都与一级认知压力和情绪压力存在正相关,而积极沟通行为,如方法指导等则与一级认知压力、情绪压力呈显著负相关;一级认知压力与正确提议比例之间存在显著负相关。     

关于城市居民心理凝聚感与压力源关系的研究

使用问卷测试方式对城市居民的心理凝聚感和压力源之问的关系进行研究。结果发现,在7种压力源因子和压力源总分中,经济收支和工作压力、家庭生活事件、知识技能更新3个压力源因子和压力源总分在三个级别的心理凝聚感组之间存在显著差异,心理凝聚感水平高的被试,对外界工作生活事件产生了最低的压力评价。职业、经济收入不同的群体在心理凝聚感的得分上存在显著的差异,经济收入高的个体有较高的心理凝聚感。说明不同心理凝聚感水平的被试面对相同的工作生活压力,其压力认知评价存在差异。     

认知评价、心理控制感、社会支持与高考压力关系的研究

采用问卷法,随机选取河北省三类中学(重点、普通、私立)324名高三考生为被试,考察了学生对高考的认知评价、心理控制感、社会支持与高考压力的关系.结果表明:(1)重点中学、普通中学学生心理控制感显著高于私立中学学生,女生在社会支持的寻求上显著高于男生;(2)积极认知评价、心理控制感和社会支持与高考压力有显著负相关,而消极认知评价与高考压力有显著的正相关;(3)消极认知评价、心理控制感和社会支持对高考压力有直接影响;而积极认知评价通过心理控制感和社会支持间接影响高考压力.     

信息呈现方式与学习者的个性特征对多媒体环境下学习效果的影响

采用两个实验:实验一以陈述性知识为学习内容,实验二以程序性知识为学习内容,在这两种情况下,分别用组间设计探讨信息呈现方式对不同认知风格和空间能力的学习者在多媒体环境下学习效果的影响。结果表明:(1)认知风格对陈述性知识在多媒体环境下的学习效果产生影响,而选择的多媒体信息呈现方式和被试的空间能力则对其不产生影响;(2)对于程序性知识的保持,多媒体信息呈现方式和被试认知风格都会对学习效果产生影响,被试空间能力则不会产生影响,而且被试不同的认知风格在不同的多媒体信息呈现方式上会产生不同的影响;(3)对程序性知识的迁移,多媒体信息呈现方式、被试认知风格和空间能力都会对多媒体环境下的学习效果产生影响,而且被试不同的认知风格和空间能力在不同的多媒体信息呈现方式上都会产生不同的影响。

怎样会让我们感觉更危险 ——风险沟通渠道分析

以实验设计与问卷测量相结合的方法,向被试提供真实的环境风险材料,探讨不同类型的（人为或自然）风险、形象性信息、不同感觉通道的信息输入（声音或文字）,以及不同沟通渠道对风险认知的影响。实验一采用实验室设计,发现人为风险比自然风险引起更高的风险认知,形象性信息的呈现增加了风险认知,但不同感觉通道的信息输入对风险认知没有影响。实验二模拟现实生活中电视和网页对风险信息的传递,比较两种沟通渠道对风险认知的影响,结果表明电视比网页唤起更高的风险认知     

压力和认知方式对基于事件错误记忆的影响

运用合作者误导信息干扰范式,通过3个实验探讨了不同压力（引导压力、警告压力和反馈压力）对不同认知方式个体的错误记忆的影响。结果表明：（1）正确引导减少了错误记忆,对改善错误记忆具有积极的作用,而错误引导则增加了错误记忆;（2）在引导压力条件下,社会警告可减少错误记忆,减少误导信息的效应;（3）肯定反馈可减少错误记忆,而否定反馈则明显增加了错误记忆;（4）不同认知方式个体在不同压力下的错误记忆方面存在差异,场依存个体受各种压力影响较大,场独立个体受影响较小。     

“攻击性行为”社会认知的实验研究

采用两种不同的方法对人类“攻击性行为”社会认知的某些特点进行探索。结果表明：①再认过程中,被试对被攻击者的辨别率（Ａ＇）明显高于攻击者,Ｂ″也具有明显特征。证明人类的外显记忆更多倾向记忆“灾难现象”。②偏好测试中,被试偏好攻击者明显多于被攻击者。证实了“攻击性行为”社会认知实验性分离的存在。也就是说学习攻击性图片在人类记忆中,产生了“攻击性行为”社会认知的启动效应。同时也证实了内隐与外显记忆之间存在任务分离的加工演变过程。③偏好测试中出现被试对陌生人（中性人物）的偏好率明显高于攻击与被攻击者的总和。我们认为这是间接启动效应,是外显记忆和内隐记忆在选择上发生冲突继而导致倾向一致的结果。     

权力对压力应对行为倾向的影响：认知评估的中介作用

摘 要 采用实验法探讨权力对压力应对行为的影响以及认知评估在二者关系中的作用。实验一通过回忆法操纵权力,测量被试在压力情境下的认知评估和行为倾向。结果发现,权力水平影响压力下的生理反应,高权力者产生挑战,低权力者产生威胁;认知评估在权力和压力应对行为倾向间起中介作用。实验二进一步探究了权力对压力应对行为的影响,结果发现认知评估中介权力和压力应对行为倾向,且不同权力水平者的压力应对行为存在显著差异。     

文化视域下认知心理学范式演进探新

认知科学的发展历程经历了符号范式、联结主范式和具身认知范式的演变。认知心理学范式演变折射出认知心理学研究方式转变和对人的心智探索的深化,同时也反映出关于身心关系实现了从传统的身心二元对立到当下身心一体论的超越;对其文化反思是引领心理学从离身认知到具身认知进程更趋合理化的基础。     

Power and Legitimizing Ideologies in Hierarchy‐Enhancing vs. Hierarchy‐Attenuating Environments

According to social dominance theory, intergroup dynamics are strongly influenced by the social positions which individuals hold in society. Several studies suggest that holding a position of power can, sometimes automatically, generate negative attitudes and hostile behaviors toward subordinate social groups. However, at present, the studies carried out on these effects of power have not taken into account the influence of the normative context. Based on the distinction made by Sidanius and Pratto between “hierarchy‐enhancing” (HE) vs. “hierarchy‐attenuating” (HA) environments, this study examines if the effects of power on legitimizing cognitions vary as a function of the normative environment. A laboratory study and a study conducted in a natural environment confirm our hypothesis that individuals holding a powerful or dominant social role in a HE setting differ significantly from individuals holding an equally powerful role in a HA setting. The effects of power observed in past research probably resulted from studying power in hierarchy‐enhancing environments, but not in hierarchy‐attenuating ones.     

社会认知复杂性的量化指标及其关系

在Kelly个人构念理论的基础上,Bieri提出用构念的分化程度衡量个体社会认知复杂性的思路,并具体用从不同构念上评价每个角色时评分的匹配个数作为复杂性的最化指标。此后,研究者从不同分析思路提出了一系列新的复杂性指标,如根据对构念的相关分析所得组内相关、RMS、SMC等,基于因素分析所得第一因素解释率、主要因素个数及其解释率等,冲突分析所得整体冲突百分比,此外还有MPP、LPP、ASO等各种Fiedler分数。本研究以402名初中一二年级青少年为被试。采用库格测验收集数据,以Gridstat4．0、Excel、SPSSl0．0等软件统计数据,分析了上述各种复杂性指标的内在关联,为同类研究选择使用这些指标提供了依据。     

靶子-靶子任务中认知控制对返回抑制的反转

使用冲突色词作为外源性线索,通过3(任务类型)×2(线索有效性)×2(色词一致性)混合设计考察认知控制对返回抑制(IOR)的影响。结果:(1)线索-靶子任务(CT)和靶子-靶子任务(TT)均产生正值IOR,CT的IOR效应量(32ms)显著大于TT(12ms)。(2)线索有效性和任务类型交互作用显著。按键反应组IOR效应量(11.85ms)显著大于颜色反应组(-18.5ms)和词意反应组(-25.65ms)。证实冲突色词在CT任务中做为线索可产生IOR,这种范式上的新尝试同样适用于TT任务。在TT任务中对认知冲突的觉察和控制导致IOR效应反转,支持注意的非盲性机制。研究为主动操纵被试对线索的认知控制程度,考察复杂任务下实施认知控制对注意定向的影响提供了一条可行途径。     

The Contributions of Memory and Attention Processes to Cognitive Abilities

In two experiments, the contributions of memory and attention processes to the cognitive abilities of reasoning and perceptual speed were investigated. Two measures of speed of information retrieval from long-term and short-term memory (Posner paradigm, Sternberg paradigm) and two attention measures (continuous attention test, attention switching test) were included in the first experiment (N = 220). The memory tests led to correlations with the measures of cognitive abilities, whereas the attention test did not. The same tests as well as one additional memory test and one attention test (working memory test, test of covert orientation) were administered in the second experiment (N = 116). Again, the memory tests led to the larger correlations with the measures of cognitive abilities. Two components were obtained in components analysis, of which the first was characterized by high loadings of the memory tests and the second by high loadings of the attention tests. Only the memory component contributed to the prediction of cognitive abilities.     

Alcohol and aggression: a test of the attention-allocation model

This article presents the first systematic test of the attention-allocation model for alcohol-related aggression. According to this model, alcohol has a "myopic" effect on attentional capacity that presumably facilitates aggression by focusing attention on more salient provocative, rather than less salient inhibitory, cues in hostile situations. Aggression was assessed using a laboratory task in which mild electric shocks were received from, and administered to, a fictitious opponent. Study 1 demonstrated that a moderate-load cognitive distractor suppressed aggression in intoxicated subjects (to levels even lower than those exhibited by a placebo control group). Study 2 assessed how varying the magnitude of a distracting cognitive load affected aggression in the alcohol and placebo conditions. Results indicated that the moderate-load distraction used in Study 1 (i.e., holding four elements in sequential order in working memory) suppressed aggression best. Cognitive loads of larger and smaller magnitudes were not successful in attenuating aggression.     

Multigroup Confirmatory Factor Analysis of the Cognitive Dysfunction Questionnaire: Instrument refinement and measurement invariance across age and sex

Vestergren, P., Rönnlund, M., Nyberg, L. & Nilsson, L.‐G. (2012). Multigroup confirmatory factor analysis of the Cognitive Dysfunction Questionnaire: Instrument refinement and measurement invariance across age and sex. Scandinavian Journal of Psychology 53, 390–400. The study adopted Confirmatory Factor Analysis (CFA) to investigate the factorial structure and reduce the number of items of the Cognitive Dysfunction Questionnaire (CDQ). The analyses were based on data for a total of 1,115 participants from population based samples (mean age: 63.0 ± 14.5 years, range: 25–95) randomly split into a refinement (N = 569) and a cross‐validation (N = 546) sample. Equivalence of the measurement and structural portions of the refined model was demonstrated across the refinement and cross‐validation samples. Among competing models the best fitting and parsimonious model had a hierarchical factor structure with five first‐order and one second‐order general factor. For the final version of the CDQ, 20 items within five domains were selected (Procedural actions, Semantic word knowledge, Face recognition, Temporal orientation, and Spatial navigation). Internal consistency reliabilities were adequate for the total scale and for the subscales. Multigroup CFAs indicated measurement invariance across age and sex up to the scalar level. Finally, higher levels of cognitive dysfunction as reflected by CDQ scores were predicted by advancing age, fewer years of education, and with deficits in general cognitive functioning as reflected by scores on the Mini‐Mental State Examination. In conclusion, the CDQ appears to be psychometrically sound and shows the expected relationships with variables known to be associated with cognitive dysfunction and dementia. Future studies should apply it among clinical groups to further test its usefulness.
