学前儿童执行功能与问题行为的关系:情境和性别的特异性

运用追踪设计检验了学前儿童执行功能特定成分和问题行为跨情境和性别的关系。选取101名学前儿童（48名男孩）为研究对象,采用实验任务测量儿童的执行功能,一年后采用母亲和教师报告分别收集儿童在家庭和学校情境的问题行为。结果发现,控制儿童年龄后：（1）在男孩中,抑制控制、认知灵活性和工作记忆负向预测一年后家庭情境的外化问题,认知灵活性负向预测一年后学校情境的外化问题,抑制控制正向预测一年后学校情境的内化问题;（2）在女孩中,执行功能三个成分均不能显著预测家庭情境的问题行为,认知灵活性正向预测一年后学校情境的外化问题。执行功能三个成分与问题行为间存在不同效应模式,且存在跨情境和性别的特异性。     

冯契对马克思主义哲学的创新性探索

作为当代著名的马克思主义哲学家,冯契对马克思主义哲学做了三方面的创新性探索。首先,丰富和拓展了马克思主义认识论体系：将狭义认识论拓展为广义认识论,充实了认识论中“知觉”和“意见”两个范畴,将“疑问”和“观点”两个普通概念提升为认识论的范畴。其次,建构了独特的马克思主义辩证逻辑体系：探讨了怎样将哲学理论化为思维方法,建构了以“类”“故”“理”为骨架的逻辑范畴体系,概括了辩证逻辑方法论的五个环节。再次,梳理与概括了中国古代自然科学成就：运用与发展了比类取象、比类运数的科学方法,设计、运用了实验手段。     

Culture and the distinctiveness motive: constructing identity in individualistic and collectivistic contexts

The motive to attain a distinctive identity is sometimes thought to be stronger in, or even specific to, those socialized into individualistic cultures. Using data from 4,751 participants in 21 cultural groups (18 nations and 3 regions), we tested this prediction against our alternative view that culture would moderate the ways in which people achieve feelings of distinctiveness, rather than influence the strength of their motivation to do so. We measured the distinctiveness motive using an indirect technique to avoid cultural response biases. Analyses showed that the distinctiveness motive was not weaker-and, if anything, was stronger-in more collectivistic nations. However, individualism-collectivism was found to moderate the ways in which feelings of distinctiveness were constructed: Distinctiveness was associated more closely with difference and separateness in more individualistic cultures and was associated more closely with social position in more collectivistic cultures. Multilevel analysis confirmed that it is the prevailing beliefs and values in an individual's context, rather than the individual's own beliefs and values, that account for these differences.     

大学生创业成功技能的结构维度探索

采用访谈法、问卷评定和因素分析法,考察了大学生创业成功技能的结构维度,并开发了中国情境下大学生创业成功技能的评定工具。研究结果表明：（1）大学生创业成功技能包括两个基本维度六个因素,其中“自我技能”包括自我管理、职业规划和信息选择与应用三个因素,而管理与影响技能包括企业管理与战略、客户管理和人际沟通三个因素;（2）基于二维度六因素模型开发的《大学生创业成功技能调查问卷》包括23个有效评定项目,其结构效度和内部一致性信度达到可接受水平,可以用于大学生创业成功技能的自我评定。     

幼儿语言发展中的形状偏好现象及其认知机制

形状偏好是指儿童语言发展过程中倾向于认为相同形状的物体拥有相同名称的现象。已有研究采用词汇拓展、分类和归纳推理等任务发现, 2~3岁甚至更早的幼儿就已经表现出形状偏好, 且表现受刺激物的属性、创造者的意图和功能及因果/比较关系等因素影响。然而, 形状偏好现象存在着联结观和概念观两种不同的解释。未来的研究应该采用认知神经科学的方法, 并结合发展中的其它问题, 从特殊被试和跨文化的角度来探讨这一现象的神经机制。     

充分条件句语义关系知觉对条件推理的影响

作者通过实验考察了大学生被试对五种充分条件句语义关系知觉对其条件推理的影响。两个实验的结果表明,被试对条件句中前后件之间语义关系的知觉理解影响和调节其相应的条件推理的成绩。实验1新发现,被试对充分条件句后件对前件必要性的知觉理解存在难易差异,对许可句和定义句的后件必要性容易知觉,对偶然句、义务句和因果句的后件必要性难以知觉。实验2新发现,被试对充分条件句后件对前件必要性的知觉理解的难易差异导致被试在否定后件式推理成绩上的差异,对许可句和定义句的否定后件式推理成绩显著高于对偶然句、义务句和因果句的否定后件式推理成绩,对充分条件句否定后件式推理成绩随对后件必要性知觉增加而增加。     

Precipitate characteristics and selected area diffraction patterns of the β′ and Q′ precipitates in Al–Mg–Si–Cu alloys

In this study, the precipitate characteristics and selected area diffraction patterns (SADP) of the β?′ and Q?′ precipitates formed at the over-aged state of Al–Mg–Si–Cu alloys are systematically investigated by means of high-resolution transmission electron microscopy and transition matrix. The β?′ precipitates have two cross-sections, rectangle-shaped and round-shaped aligned with [0?0?1]_Al direction, but only rectangle-shaped cross-section exists for Q?′ precipitates. And, both of them have 12 variants and orientations with Al matrix. However, there are only three different zone axes, [0?0?0?1]_β?′, [1?4?5?0]_β?′, and [5?4?1?0]_β?′ for β?′ precipitates, and [0?0?0?1]_Q?′, [1?4?5?0]_Q?′, and [3?2 1?0]_Q?′ for Q?′ precipitates, parallel to the [0?0?1]_Al direction when they are precipitated from the Al matrix, respectively. Then, a new [0?0?1]_Al SADP model, which superposes diffraction patterns of the β?′ and Q?′ precipitates, is established. Furthermore, some “cross-shaped” diffraction streaks appeared at over-aged state can be explained reasonably by this model, which is good in agreement with the experimental data.     

The Relationship Among Child Maltreatment,Parental Bonding,and a Lifetime History of Major Depressive Disorder in Latino College Students

This study examined the relationship among child maltreatment, parental bonding, and a lifetime history of major depressive disorder (MDD) in a sample of 119 Latino students. Forty-five students reported a lifetime history of MDD and 74 reported not having a lifetime history of MDD. The results indicated that emotional abuse and maternal overprotection were significantly associated with having a lifetime history of MDD. The findings support the importance of examining these factors among depressed Latinos. Future research should continue to explore both the role of child maltreatment and parental bonding in relation to a lifetime history of MDD in this population.

A Model of Chinese Adolescents' Creative Personality

Since the 1950s, there has been a systemic development of research on creative personality. Three themes are apparent in this literature: individual differences of creative people, the construct of creative personality, and longitudinal studies about creative personality. However, little research has been conducted in any of these areas with Chinese samples, and the purpose of this study is to study the construct of Chinese adolescents' creative personality. Confirmatory factor analyses were conducted with data from 1,300 Chinese adolescents. The results provide evidence that adolescents' creative personality consists of three largely independent dimensions: Internal, External, and Self. The internal factor includes self-confidence, norm-doubt, internal motivation, and persistence; the external factor includes curiosity, risk-taking, openness and independence; the self factor pertains to self-acceptance.
