What Matters Most to the Left-Behind Children’s Life Satisfaction and School Engagement: Parent or Grandparent?

This study compared the role of the parent and grandparent in the adjustment of children who had, and who had not, been left behind when their parents moved to urban areas for work, and tested whether self-esteem mediated the association between these family relationships and child adjustment. The sample included 428 middle school students in central China, 204 of whom were left-behind children who were cared for by grandparents and 224 of whom were not left behind. The students responded to five questionnaires measuring parent–child relationships, grandparent–child relationships, self-esteem, life satisfaction and school engagement. Regression analyses showed that self-esteem mediated the association between parent–child and grandparent–child relationships and children’s adjustment, but there were different patterns of association for the non-left-behind children and left-behind children groups. Furthermore, the unique effect of parent–child relationships was higher than that of grandparent–child relationships for the non-left-behind children, but for the left-behind children, grandparent–child relationships played a more important role than grandparent–child relationships in predicting their school engagement, and parent–child relationships played a more important role in predicting their life satisfaction. Parents who are far away and grandparents who are close at hand can shape different psychological and behavioral development outcomes of left-behind children.     

Perceiving high social mindfulness during interpersonal interaction promotes cooperative behaviours

Social mindfulness refers to individual's respect and protection of others’ options in interpersonal interaction. The object‐choosing task is a traditional paradigm to assess social mindfulness. Individuals with high social mindfulness would choose the nonunique object so that others would have more options; on the contrary, individuals with low social mindfulness would choose the unique object, which limits others’ choices. No prior study has examined whether perceiving people with different levels of social mindfulness affects one's cooperation. Based on this background, two experiments were conducted to address this question. In both experiments, a confederate participant's (Player A's) social mindfulness was manipulated by setting the frequency that Player A chose the unique and the nonunique objects. Then, participants were asked to interact with Player A in the public goods game (Experiment 1) or in the centipede game (Experiment 2). Convergent results showed that compared to those interacting with a socially unmindful person, participants interacting with a person perceived as socially mindful contributed more resources in the public goods game and chose to pass on more rounds in the centipede game. These findings suggest that perception of others’ high social mindfulness enhances one's own cooperative behaviour.     

“和而不同”：中西文化下人际互动和谐相容模型比较

孔子提出“君子和而不同,小人同而不和”的和谐伦理观。“和”是中国传统文化的一个核心概念,在中国古代哲学思想中,“同”与“和”是一对相互联系又相互区别的概念。现代心理学从人际理论和社会认知理论都阐述了同与和的关系。人际理论家分别从特质、情境和行为互动层面提出互补匹配与和谐的关系,而社会认知理论家以自我和他人相似特质为起点,建构了以感知水平和情感为中介的相似性和谐模式。本文结合以往实证研究结果,提出了中国传统文化下,“和而不同”的思想贯穿于整个人际互动的过程中,同时关系层面是影响互动双方评价互动和谐的一个重要因素．     

大学生在双趋冲突和趋避冲突中的折扣率差异

目的探讨大学生被试在双趋冲突和趋避冲突条件下的折扣率差异。方法让70名大学生完成两种条件下的延迟折扣任务（DDT）。结果趋避冲突条件下大学生被试的折扣率显著低于双趋冲突条件下的折扣率,在延迟奖赏为中幅度（50-60元）时折扣率最大。结论相对于双趋冲突,损益情况和延迟时间同时影响着被试在趋避冲突条件下的选择。     

探索性因素分析因子抽取方法的比较

探索性因素分析决定因子抽取的方法主要有Bartlett法、K1原则、碎石检验法、Aaker原则、PA、MAP等六种,通过对样本1的395名大学生的学习过程问卷调查获得真实数据,运用这六种方法进行因素分析分别抽取7、4、2、4、3、2个因子;应用样本2的383名大学生的问卷调查数据进行验证性因素分析,结果显示,碎石检验方法与MAP方法抽取的二因素模型更理想。研究表明,因子抽取需兼顾“简约性原则”与“完备性原则”,同时要根据一定的理论建构、专业知识和经验来决定因子数。     

意识锚定加工对潜在锚定加工的影响

潜在锚定效应是指阈限下的启动锚定数字导致的锚定效应现象。本研究通过2个实验探讨了意识锚定加工对潜在锚定加工的影响。实验一考察了意识层面的外在锚对潜在锚定效应产生的影响,实验二则进一步探讨了意识层面的自发锚对潜在锚定效应的影响。实验一发现,在不存在外在锚时高锚与低锚的估计有显著性差异;实验二发现,在不存在自发锚时高锚与低锚的估计有显著性差异。研究结果表明,外在锚定加工和自发锚定加工的效应都强于潜在锚定加工。     

群体认同、自尊和心理疾病污名的关系

通过对620位在校大学生进行问卷施测,探讨大学生群体认同、自尊和心理疾病污名之间的内在关系,并使用LISREL 8.70建构了彼此之间的关系模型,进行了中介效应分析.结果发现:(1)群体认同显著地负向预测自我污名,且通过自尊和公众污名这两个中介变量影响自我污名;(2)自尊显著负向预测自我污名,公众污名显著正向预测自我污名.结论:三个变量之间相关非常显著;所建构的模型具有较高的拟合度.     

工作记忆负荷对注意捕获的影响研究

注意捕获研究对于探讨两种控制过程:自上而下的加工与自下而上的加工之间的关系具有重要的意义。本文通过检验不同工作记忆负荷对注意捕获的影响,探讨自上而下的认知控制对注意捕获的影响机制。本研究共包括二个实验:实验一比较了单、双任务条件对颜色干扰子注意捕获的影响;实验二探讨了不同工作记忆负荷对颜色干扰子注意捕获的影响。实验结果表明:工作记忆不仅在选择性注意任务中具有认知控制作用,而且这种作用能扩展到注意捕获现象中。注意捕获不是纯粹的刺激驱动的加工过程,它还受到自上而下的认知控制的调节。具体表现为,随着工作记忆负荷水平的增加,无关干扰子产生的注意捕获的程度增大。     

可预测性和空格对中文阅读影响的眼动研究

实验采用EyeLink II 眼动仪,以30名大学生为被试,采用2（预测性：高、低）×3（空格：正常无空格、词间空格、非词空格）被试内设计,考察了预测性和空格对中文阅读影响,探讨了模块化理论和相互作用理论的争论。结果发现：词的预测性和空格两因素的主效应显著,但二者之间无交互作用,符合模块化理论的预期。
