涉空对话中表征对齐的产生机制

人类如何处理并交换空间信息是现有空间认知领域的热点问题, 这一过程主要是通过涉空对话实现的。在涉空对话中存在着表征对齐现象, 互动双方在对话中会实现空间术语、空间参照系及空间视角等表征的对齐。空间场景物理特征和人与人的协作都会影响表征对齐的程度, 而实现表征对齐的生理基础是对话双方神经活动的一致性。未来可继续探究表征对齐的作用机制, 如与个体空间偏好的关系, 以及合作伙伴特征如何影响表征对齐的程度等。     

对话心智与身体：具身认知的内感受研究转向

具身认知观念试图强调心智是根植于身体的,身体经验会对认知过程产生重要影响。但对于心智与身体的对话是如何进行的？身体通过何种渠道如何影响心智？等问题困扰着具身认知的支持者。传统的具身认知研究遭遇可重复性危机,身体状态改变影响高级认知的结论受到质疑。近年来,越来越多的证据表明内感受与身体表征、具身情绪以及社会认知等存在着密切的联系,因而内感受很有可能在身体加工和高级认知过程中起着重要的调节作用。     

自闭症谱系障碍个体的共情干预：扬长还是补短?

自闭症谱系障碍(autism spectrum disorders, ASD)个体的共情能力缺陷可能导致了他们的社会交往障碍, 因此有必要对ASD个体的共情能力进行干预。有研究者主张应该对ASD个体的共情缺陷进行直接干预, 由此衍生了共情“补短”法, 主要包括心理理论的干预、观点采择的干预、面部表情认知的干预等几种方法。另有一些研究者认为虽然ASD个体存在共情缺陷, 但他们同时也具备系统化能力优势, 应该通过ASD个体的优势能力来改善其共情能力, 由此衍生了共情“扬长”法, 主要包括乐高治疗、严肃游戏干预、基于系统化理论的孤岛能力辅助干预等几种方法。每种方法都存在优点和不足。最后就目前ASD个体共情干预领域存在的问题进行了反思与展望。     

汉语发展性阅读障碍儿童视觉注意广度的发展及其对阅读流畅性的作用

以85名小学2~6年级儿童为研究对象,采用方差分析、分层回归探讨小学高、低年龄阶段发展性阅读障碍儿童视觉注意广度的发展变化,并以同年龄正常阅读者作为对照组;同时在不同年龄阶段探究视觉注意广度对阅读流畅性发展的预测作用。结果显示：（1）发展性阅读障碍儿童存在视觉注意广度缺陷,并呈现出在小学高年龄阶段更严重的趋势;（2）在阅读障碍儿童中,视觉注意广度对汉语流畅阅读的显著预测作用随发展增强;而对于正常阅读者,视觉注意广度仅显著预测低年龄段学生的句子朗读流畅阅读能力。以上结果表明视觉注意广度与汉语流畅阅读能力关系密切,今后汉语阅读障碍的相关干预研究可以尝试从视觉注意广度训练方面切入。     

字谜顿悟任务中限制解除和组块分解的机制及其原型启发效应

通过3个实验考察了汉字字谜任务中的限制解除和组块分解机制及其原型启发效应。实验1a表明,字谜的常规型语义比字谜型语义更容易激活,实验1b采用“学习-测试”范式,结果表明在学习阶段启动字谜语义比启动常规语义更有利于测试阶段的常规语义限制的解除。因此实验1表明常规语义和字谜语义的通达性差异是限制形成和限制解除的认知机制。实验2表明,涉及镶嵌或者笔画单元分解的紧组块比相应的松组块解答率更低,反应时更长,这表明组块分解是字谜顿悟的机制之一。实验3通过实验3a和实验3b分别揭示了在限制解除和组块分解上原型启发比非原型启发以及无启发有更大的促进作用。总之,本研究揭示,汉字字谜任务中存在限制解除和组块分解机制并且原型启发可以促进二者的发生。     

问题结构因素对伦敦塔问题解决的影响

以121名2,4,6年级小学生为被试,采用计算机呈现的方式,探讨了子目标和次佳路径这两个问题结构因素对伦敦塔问题解决表现的影响。结果发现：子目标和次佳路径两个因素存在交互作用,解决有子目标－无次佳路径问题时的计划指标要高于其他类型问题。根据被试在伦敦塔任务上的表现,划分为三大类7种表现类型。当存在不同的问题结构因素时,问题解决表现类型体现出差异性。

The number of only children in China has increased rapidly since the late 1970s, when the Chinese government advocated the “one-child-per-family” policy. This increase has caused much public concern about the healthy growth of the young generation. In this study the behavioral traits of Chinese, urban, only children were investigated. The participants were 444 children with siblings and 473 only children from Grades 1, 3, and 5 in Beijing primary schools. An inventory consisting of 27 items covering three behavioral traits was developed. The children were rated on the inventory by the principal teacher of the class. Factor analysis revealed three main factors: achievement motivation, interpersonal skills, and attitude toward manual labor. The only children exceeded the sibling children on achievement motivation. No differences were found between only children and sibling children on interpersonal skills and attitude toward manual labor. Gender differences were evident; girls consistently received higher ratings on achievement motivation and interpersonal skills. The possible underlying reasons for these differences are discussed.     

Gender Differences in Coping Styles of Chinese Military Officers Undergoing Intensive Training

This study investigated gender differences in anxiety and coping styles under the stress of intense military training. We surveyed Chinese female (n = 470) and male (n = 379) military officers who were surveyed during the third month of a 10-month intensive training program. Results indicated that state and trait anxiety were highly correlated in both women and men. In general, female officers had higher levels of anxiety, greater negative coping tendencies, and less perceived self-efficacy than their male counterparts. When compared with the norm, both women and men had significantly more positive coping strategies. A hierarchical multiple regression analysis showed factors that influenced male and female state anxiety. Avoidance, which was chosen by women more often than men, in general was less useful for female officers. The most common positive coping style for female officers was problem solving, whereas for men it was help seeking. We suggested that even female officers with lower mental health levels than their male counterparts made active cognitive changes to their coping styles when undergoing intense military training.     

Emotional expressions facilitate human–human trust when using automation in high-risk situations

This study investigated the utility of emotional expression for human decision aids, when human aids conflict with an automated decision support system (DSS). The increasing presence of automation in society has resulted in critical, and often life threatening, situations when information from human and automated sources disagree. It has been known that reliance on human aids decrease during high-risk situations, while reliance on automated aids increase. However, it is also possible that human decision aids gain credibility from users when they embody the charismatic and emotionally expressive gesticulations seen in successful organizational leaders. The present study tested how a human agent's expressiveness when providing information would influence participants' behavioral reliance. Using the program Convoy Leader, participants (n=56) engaged in three decision-making scenarios where risk was manipulated as a within-subject factor and emotional expression as a between-subject factor. Emotional susceptibility, perceived risk, and trust for human as well as automated aids were measured. Overall trust was higher for the automated tool than human decision aid, and that pattern was amplified in conditions without an emotionally expressive human aid. Reliance was greater for emotionally expressive human aids, than stoic human aids, particularly during high risk conditions. The findings suggest that emotional expression of a human aid significantly impacts both reliance and trust of a decision aid, especially at higher risk levels. Emotionally expressive human agents should be utilized in decision conflicts where the automated system has certainly failed.     

Study of γ/γ′ interfacial width in a nickel-based superalloy by scanning transmission electron microscopy

The γ/γ′ interfaces are thought to play an important role in determining the mechanical properties in single-crystal nickel-based superalloys. In this article, interfacial width in DD6, one second-generation single-crystal superalloy containing 2 wt% Re, has been studied by means of scanning transmission electron microscopy. From an atomic resolution high angle annular dark field image, both compositional interfaces and order–disorder interfaces are studied, and it is first found that the interfacial width of chemical composition is same with that between the ordered and disordered phases.
