Stomaching rejection: Self-compassion and self-esteem moderate the impact of daily social rejection on restrictive eating behaviours among college women

Objective: The present study examined whether having high self-esteem or a self-compassionate perspective help mitigate the impact of daily social rejection on negative affect and restrictive eating behaviours.

Design: Following a baseline survey assessing self-esteem and self-compassion, 121 college women completed online daily diaries for one week.

Main Outcome Measures: Negative affect and restrictive eating behaviours.

Results: On days when women reported more rejection, they also reported higher restrictive eating behaviours and greater negative affect. Effects were moderated by self-esteem and self-compassion, such that the lower participants were in self-esteem or self-compassion, the stronger the positive relation between rejection and negative affect and restrictive eating. However, only the common humanity/isolation dimension of self-compassion significantly moderated daily effects of rejection when controlling for self-esteem. Mediated moderation results reveal different mechanisms by which self-esteem and self-compassion buffer against rejections’ effects on affect and restrictive eating.

Conclusion: Self-compassion and self-esteem influence the complex impact that social rejection has on affect and restrictive eating. More than other dimensions of self-compassion or self-esteem, remembering one’s common humanity can result in a healthier response to social rejection.     

Genetic and Environmental Pathways Underlying Personality Traits and Perceived Stress: Concurrent and Longitudinal Twin Studies

The present study examined the genetic and environmental etiology underlying the Big Five personality traits and perceived stress, concurrently and longitudinally. In study 1, we used the twin sample from the National Longitudinal Study of Adolescent to Adult Health (Add Health IV) data. The results indicated that about 70% of the association between the Big Five personality traits and perceived stress was due to genetic influences. In study 2, we used the twin sample from the Midlife in the United States Survey (MIDUS I and II) to examine the genetic and environmental influences underlying the longitudinal relations between the Big Five personality traits and perceived stress. The results suggested that continuity in perceived stress was primarily accounted for by genetic influences, and changes in perceived stress were mainly due to nonshared environmental influences. The continuity in the association between the five personality traits and perceived stress was largely accounted for by genetic factors, and nonshared environmental factors made greater contributions to changes in the association between personality traits and perceived stress. Among the Big Five personality traits, the genetic components in conscientiousness and neuroticism made substantial contributions to the genetic link between personality traits and perceived stress across both studies.

流动性、教育安置方式和心理弹性对流动儿童孤独感的影响:一项追踪研究

采用潜变量增长模型对426名流动儿童进行四次追踪测查,旨在考察流动儿童孤独感的变化趋势,探索不同流动性和教育安置方式的流动儿童孤独感变化的差异性以及心理弹性对孤独感变化的促进性作用。结果发现：（1）流动儿童的孤独感呈线性下降趋势;（2）打工子弟学校流动儿童的孤独感起始水平显著高于公立学校流动儿童;流动性高的儿童的孤独感起始水平高于流动性低的儿童,但流动性和教育安置方式对孤独感的发展趋势没有显著预测作用;（3）对于流动儿童来说,较高的心理弹性水平不仅能显著预测更低的孤独感起始水平,同时也能显著预测更快的孤独感的下降速率。本研究启示,增加进入公立学校学习的机会、降低流动频率和提升心理弹性对降低流动儿童的孤独感水平具有重要的意义。     

母亲元情绪理念与学前儿童社会适应的相互作用关系

采用追踪设计对438名学前儿童母亲进行问卷调查研究,主要探讨了母亲元情绪理念与学前儿童社会适应的相互作用关系。交叉滞后分析结果表明：（1）相邻两次测量的母亲各元情绪理念之间,社会适应各指标之间均具有中等程度的稳定性;（2）同一时间点的母亲各元情绪理念与儿童社会适应各指标之间均显著相关;（3）母亲元情绪理念与儿童社会适应之间部分存在着相互作用关系：控制了变量自身的连续性后,前测的母亲情绪教导显著正向预测后测的儿童敏感合作;前测的母亲情绪不干涉显著正向预测后测的儿童愤怒攻击、焦虑退缩行为;反过来,前测的儿童敏感合作能正向预测后测的母亲情绪教导,显著负向预测情绪不干涉、情绪摒除和情绪紊乱;前测的焦虑退缩能显著正向预测后测的母亲情绪摒除和情绪紊乱。     

阅读中的快速启动范式述评

快速启动范式（Sereno & Rayner, 1992）是一种基于呈现随眼动变化技术而设计的眼动范式,主要用于研究中央凹视野内字词识别的瞬时启动,通过精确控制启动条件和启动时窗,以考察词汇通达过程中词汇水平（如,词频、词长等）、亚词汇水平（如,语音、语义、字形等）信息的加工时序。本文从基本原理、设计基础、应用领域、注意事项等方面对快速启动范式进行了较为深入的解读和介绍,并结合已有的研究成果,指出了该范式在汉语阅读中的应用价值。

适宜技术与诊疗最优化的可行性研究

在案例分析的基础上,作出了医生是临床诊疗中适宜技术的主要选择者的判断;论证了运用适宜技术实现诊疗最优化的可行性;认为适宜技术难以选择和实施的主要原因是利益关系、责任心不强和管理措施不到位;提出了必须着力培育适合于适宜技术生长的土壤的对策,即:实行政策引导与资金支持、进一步加大监管力度、营造良好的氛围、高度重视并加强医生道德素质的培养.     

学习动机、元认知对学业成就的影响

以202名大学生为被试,测量研究了学习动机、元认知与学业成就的关系．结果表明,元认知、学习动机与学业成就之间是相关的。认知驱动力、自我提高内驱力与元认知和学业成就呈正相关,而附属内驱力与学业成就呈负相关。认知驱动力和自我提高内驱力对学业成就和元认知存在显著回归效应。
