亲代孕前成瘾药物暴露对子代行为的影响及其表观遗传机制

孕前成瘾药物暴露不仅危害使用者的身体健康,而且会对子代的生理行为造成影响,近年来研究发现表观遗传机制在其中发挥重要作用。孕前成瘾药物暴露会对子代的成瘾易感性和焦虑样行为造成影响,引起子代的抑郁样行为和认知受损。这些现象可能是成瘾药物通过引起亲代生殖细胞内表观遗传修饰变化所致,其中包括印记基因、神经递质系统、BDNF三个方面的表观遗传修饰变化。此外,未来除了加强以上三个方面基因的研究,也需要增加其他方面基因的研究,以及寻找能预测子代异常行为的表观遗传生物标志物。     

The role of formal information sharing in key account team effectiveness: does informal control matter and when

Team selling is a useful approach for retaining strategically important accounts in business-to-business markets. For key account sales teams, ensuring adequate access to information about customer needs offers sustainable competitive advantages. However, the internal alignment of market information remains a recurring managerial issue in key account team selling. This study develops a moderated mediation model to identify management strategies that encourage team members' formal information sharing, which in turn improves team effectiveness. Analysis of a multilevel data set comprising 37 fluid key account teams reveals that customer orientation and task interdependence increase formal information sharing among team members. Managers' exercise of professional control strengthens the positive impact that formal information sharing has on team satisfaction. However, the practice has a dysfunctional influence on the positive effect of task interdependence on formal information sharing. Firms with key account management (KAM) programs must decide whether the marginal benefits attained by advocating such professional control outweigh the possible drawbacks.     

父母参与作业的自主动机与小学生积极作业情绪:学生作业自主动机与教师支持的作用

采用问卷调查法,以702名小学生为被试,探讨了教师支持、父母参与作业的自主动机和学生家庭作业自主动机影响积极数学家庭作业情绪的内在作用机制。结果发现：（1）父母参与作业的自主动机是积极数学家庭作业情绪的预测因素;（2）学生家庭作业自主动机在父母参与作业的自主动机与积极数学家庭作业情绪之间起完全中介作用;（3）教师支持在父母参与作业的自主动机通过学生家庭作业自主动机影响其积极数学家庭作业情绪的过程中起有中介的调节作用。研究表明,教师支持、父母参与作业的自主动机和学生家庭作业自主动机均是学生积极家庭作业情绪的重要影响因素。     

中国文化心理学视界下的音乐实质探究

从中国语言的词源上看,音乐中的"乐(yuè)"通快乐的"乐(lè)",它们都源自于"鼓",而鼓声能够令人兴奋、情绪激昂,因此,中国文化中的音乐的原初含义有"令人振奋、快乐"的声音和人在振奋、快乐时表达这种心情的声音两层意思。后来这两层含义延伸为"动情"即激发人的情感或心理感染和"传情"或"达情"即表达人的情感。基于此,创作好的音乐作品或评判一个音乐作品的好坏,要看它是否具有"言志"、"激励人或令人振奋"、"表达情感"和"培养或锻造人的积极情感或心理品质"的作用。     

父母早期受虐与子女对立违抗症状的关系:亲子虐待和儿童愤怒管理的作用

本研究探讨了父母的早期受虐经历与子女的对立违抗症状的关系,通过构建一个有调节的中介模型,考察了亲子虐待的中介效应和儿童愤怒管理对该效应的调节作用。采用问卷法对359名来自北京市、山东省和云南省的14所小学一至五年级的儿童及其父母进行调查,研究工具包括儿童对立违抗症状评估表、童年期创伤问卷、儿童愤怒管理量表。结果发现：（1）男孩的ODD症状得分显著高于女孩;男孩受到的躯体虐待、情感忽视和躯体忽视显著多于女孩（2）在控制了儿童性别后,父母在童年期的受虐经历仍可显著正向预测其成年期的家庭中子女的ODD症状;（3）亲子虐待在父母受虐和子女ODD症状之间起完全中介作用,即父母受虐通过亲子虐待间接影响子女ODD症状;（4）父母受虐通过亲子虐待影响子女ODD症状的中介效应后半路径受到子女个体水平愤怒失调（AD）的调节,具体来说,当AD水平较高时,亲子虐待对ODD症状的影响更大;但愤怒应对（AC）和愤怒抑制（AI）对中介效应无显著调节作用。     

大学生成就目标定向与学习投入的关系:时间管理倾向的中介作用

采用成就目标定向量表、青少年时间管理倾向量表和学习投入量表,对721名大学生进行调查,探讨大学生时间管理倾向在成就目标定向与学习投入之间的中介作用,同时考察受到学籍警告学生、普通学生和获奖学金学生在这三者上的得分是否有差异。结果发现:(1)在成就目标定向上,普通组与获奖学金组学生存在显著差异,而在时间管理倾向与学习投入上则差异不显著,但两组学生在这三者上的得分皆要显著高于受学籍警告组学生;(2)大学生掌握目标定向、成绩趋近目标定向与时间管理倾向和学习投入皆呈显著正相关,而成绩回避目标定向与学习投入呈显著负相关,与时间管理倾向则相关不显著;(3)时间管理倾向在成就目标定向与学习投入之间起完全中介作用,表明大学生的成就目标定向通过时间管理倾向间接影响其学习投入。     

二语情绪概念理解中的空间隐喻

采用空间启动范式考察二语情绪概念理解中是否激活空间信息, 即是否存在空间隐喻。实验1探讨单通道二语情绪概念理解中的空间隐喻, 实验2则探讨跨通道二语情绪概念理解中的空间隐喻。实验1中让32名母语为汉语的汉-英双语者先看一个英文情绪词, 接着进行视觉空间位置判断, 最后再让被试判断之前呈现的情绪词是积极词还是消极词。实验2中40名母语为汉语的汉-英双语者完成跟实验1类似的任务, 不同之处为英文情绪词以听觉形式呈现。两个实验的结果表明, 跨语言和跨通道的情绪词的空间隐喻受到空间位置方向的影响。垂直位置方向上, 二语情绪词在单通道和跨通道中都表现出了空间隐喻; 水平位置方向上, 二语情绪词没有表现出空间隐喻。该结果说明了情绪概念的空间隐喻会受到个体经验的影响, 进一步支持了知觉符号理论。     

Bootstrap standard error and confidence intervals for the correlations corrected for indirect range restriction

The standard Pearson correlation coefficient, r, is a biased estimator of the population correlation coefficient, ρ(XY) , when predictor X and criterion Y are indirectly range-restricted by a third variable Z (or S). Two correction algorithms, Thorndike's (1949) Case III, and Schmidt, Oh, and Le's (2006) Case IV, have been proposed to correct for the bias. However, to our knowledge, the two algorithms did not provide a procedure to estimate the associated standard error and confidence intervals. This paper suggests using the bootstrap procedure as an alternative. Two Monte Carlo simulations were conducted to systematically evaluate the empirical performance of the proposed bootstrap procedure. The results indicated that the bootstrap standard error and confidence intervals were generally accurate across simulation conditions (e.g., selection ratio, sample size). The proposed bootstrap procedure can provide a useful alternative for the estimation of the standard error and confidence intervals for the correlation corrected for indirect range restriction.     

Developmental Trajectories of Maladaptive Perfectionism in Middle Childhood

The developmental trajectories of maladaptive perfectionism, along with their consequences and origins, were examined in middle childhood. A sample of Singaporean children and their parents (N = 302) were recruited for a longitudinal study when the children were 7 years old. Subsequent follow‐up assessments were made at ages 8, 9, and 11. A multimethod approach was adopted where parent reports, child reports, and observational data on a dyadic interaction task were obtained. Using latent class growth modeling, four distinct classes were obtained for critical self‐oriented perfectionism (SOP‐C), whereas two classes emerged for socially prescribed perfectionism (SPP). Children with high and/or increasing SOP‐C and SPP trajectories constituted 60% and 78% of the sample, respectively. For both SOP‐C and SPP, trajectories with high initial status were associated with higher internalizing and externalizing symptoms. Parental intrusiveness and negative parenting predicted high and/or increasing SOP‐C trajectories, whereas the child temperament dimension of surgency predicted high SPP trajectory. Both SOP‐C and SPP trajectories tended to co‐occur, suggesting a mutually reinforcing process. This study yields important findings that help advance current understanding of the emergence and developmental pathways of maladaptive perfectionism in children.
