大学生创造性内隐观的调查研究——关于高创造性者的特征

本研究采用社会效度的方法,对大学生的创造性内隐观进行了调查研究,结果发现：1．大学生的创造性内隐观所涉及的范围广泛,涵盖了认知、人格的许多方面;2．经因素分析把大学生的创造性内隐观可以概括为十二个因素,分别是：道德品质、才情、异常人格、独创力、探究、自主敢为性、思维发散性、知识经验、勤勉、问题发现、智力、自强,其中道德品质和勤勉为中国大学生所特有。3．不同专业和性别的大学生在上述诸因素上内隐观总体差异显著,并且二者交互作用总体显著,在各具体因素上内隐观有些也存在不一致。     

Attitudes Toward Affirmative Action: Correlations With Demographic Variables and With Beliefs About Targets,Actions, and Economic Effects1

Two studies assessed beliefs and attitudes toward affirmative action in the workplace. Opposition to affirmative action was most strongly associated with respondent race (White) and political conservatism, the belief that it involves strong actions (preferential hiring and setting aside jobs), and the expectation that it will hurt company performance. Attitudes were also positively associated with perceived frequency of employment discrimination experienced by the target group and negatively associated with their resulting employment opportunities. Regression results revealed that economic consequences for the company overwhelmed beliefs about target group employment opportunities in predicting affirmative action attitudes. Respondents associated aftirmative action most strongly with Black and Hispanic targets, and White respondents whose affirmative action schemas featured these 2 targets had the most negative attitudes.     

视觉工作记忆中的特征捆绑

特征捆绑是认知科学和神经科学研究的前沿问题,近来已经成为研究者们关于意识问题争论的焦点所在。很多心理活动涉及复杂对象各种特征的捆绑,在工作记忆中保持这些捆绑的机制是心理加工得以有效进行的基础。视觉工作记忆中的特征捆绑近来成为研究热点之一,有关研究大多凭借变化检测范式和单刺激探测范式,探讨了视觉工作记忆中捆绑特征的保持是否需要注意参与,以及分离特征存储和捆绑特征存储的关系等问题,但目前这些问题仍都没有明确的答案。     

样例数量对内隐序列学习的影响

本研究采用序列学习范式,探讨了样例数量对内隐序列学习的影响,以揭示意识在学习中的作用以及内隐学习获得的知识表征。研究发现,在内隐序列学习中：（1）被试既可以记忆具体的样例知识也可以抽取抽象的规则知识;（2）样例数量影响被试对样例和规则知识的获得,在样例较少时被试可以获得更多的样例和规则知识;（3）样例数量影响被试对意识知识的获得,在本研究中仅当样例数为4时被试获得了有关样例和规则的意识知识。     

中学生自我导向学习倾向性量表的结构和效度

本研究的目的是修订中学生自我导向学习倾向性量表,探讨它的结构和效度。研究参考台湾修订版对Guglielmino量表进行翻译,构成量表;结合内外控量表、学业成就归因量表和学业自我效能感量表,有效测试了1000名中学生,采用信度分析、因素分析和外部效标分析等方法考察量表的结构和效度。结果发现6个因子结构最优,α分别为0.861,0.791,0.809,0.630,0.888,0.781,各个条目的因子负荷介于0.30-0.69。6因子结构模型的各项拟合指标都在0.90以上,6因子与各个效标的相关为大多达到了显著性水平。研究的结论是修订的中学生自我导向学习倾向量表具有良好的6因子结构和信效度。     

认知能量模型--一种更为综合的ADHD认知理论

认知能量模型是J.A.Sergeant等人提出的一种解释ADHD缺陷机制的综合性实证理论。该模型基于信息加工理论,结合了状态因素理论和几种相对成熟的模型,尝试对ADHD提供一种较为理想的解释。本文在此对该模型的基本观点、模型结构及其有关的实证研究进行介绍,并探讨认知能量模型对于未来ADHD研究的启示。     

Face value: testing the utility of contextual face cues for face recognition

The presence of multiple faces during a crime may provide a naturally-occurring contextual cue to support eyewitness recognition for those faces later. Across two experiments, we sought to investigate mechanisms underlying previously-reported cued recognition effects, and to determine whether such effects extended to encoding conditions involving more than two faces. Participants studied sets of individual faces, pairs of faces, or groups of four faces. At test, participants in the single-face condition were tested only on those individual faces without cues. Participants in the two and four-face conditions were tested using no cues, correct cues (a face previously studied with the target test face), or incorrect cues (a never-before-seen face). In Experiment 2, associative encoding was promoted by a rating task. Neither hit rates nor false-alarm rates were significantly affected by cue type or face encoding condition in Experiment 1, but cuing of any kind (correct or incorrect) in Experiment 2 appeared to provide a protective buffer to reduce false-alarm rates through a less liberal response bias. Results provide some evidence that cued recognition techniques could be useful to reduce false recognition, but only when associative encoding is strong.     

Asian Couples in Negotiation: A Mixed‐Method Observational Study of Cultural Variations Across Five Asian Regions

The purpose of this study was to explore variations in how contemporary couples from five different Asian regions negotiate disagreements. Video recordings of 50 couples (10 each from Japan, Korea, Mainland China, Taiwan, and Hong Kong) discussing unresolved disagreements provided raw data for quantitative and qualitative analyses. First, teams of coders from each region used a common protocol to make quantitative ratings of content themes and interaction patterns for couples from their own region. An interregional panel of investigators then performed in‐depth qualitative reviews for half of these cases, noting cultural differences not only in observed patterns of couple behavior but also in their own perceptions of these patterns. Both quantitative and qualitative analyses revealed clear regional differences on dimensions such as overt negativity, demand‐withdraw interaction, and collaboration. The qualitative results also provided a richer, more nuanced view of other (e.g., gender‐linked) conflict management patterns that the quantitative analyses did not capture. Inconsistencies between qualitative and quantitative data and between the qualitative observations of investigators from different regions were most pronounced for couples from Korea and Japan, whose conflict styles were subtler and less direct than those of couples from the other regions.     

Thermal expansion coefficients of Mo-Si compounds by first-principles calculations

Taking Mo-Si compounds as model systems, we show that the coefficients of thermal expansion (CTEs) of complex structures can be calculated precisely from first principles by incorporating the Debye model for acoustic response. Specifically, we obtain a nearly isotropic CTE in MoSi₂ but a highly anisotropic CTE in Mo₅Si₃. The CTE anisotropy in Mo₅Si₃ is due to an elastically more rigid basal plane and a higher anharmonicity along the c axis. As the structure of 5-3 compounds is modified from D8_m to D8_l by boron substitutions (Mo₅SiB₂), we predict a significant decrease in the CTE anisotropy, which is confirmed by experiments.
