差异化变革型领导对知识分享与团队创造力的影响:社会网络机制的解释

差异化变革型领导是团队领导领域的最新议题,现有的研究局限于探讨其社会心理方面的作用机制。本文从社会网络机制出发解释差异化变革型领导对团队知识分享及团队创造力的影响。基于65家企业的225个工作团队样本的结构方程模型分析表明,团队一致性变革型领导正向影响团队交流网络密度从而提高团队知识分享;个体差异性变革型领导正向影响团队成员交流网络密度差异性从而降低团队知识分享;团队知识分享正向影响团队创造力。本文的证据表明,在中国情境下,差异性团队领导行为不利于创造稠密的团队交流网络,以及团队知识分享,从而不利于提升团队创造力水平。     

中文阅读中的预视效应与词切分*

通过眼动随动显示技术操作注视点右侧文字的掩蔽范围和掩蔽单元,考察中文阅读的预视效应和词切分现象。研究包括两项实验。实验一以词为单元掩蔽注视点右侧的文字,发现词 n 右侧文本掩蔽(条件1)、词n+1右侧文本掩蔽(条件2)和词n+1掩蔽(条件3)均显著影响总阅读时间。其中,条件2剥夺了词n+1以右文字的预视加工,同时提供了词n+1的右侧边界线索,结果导致总阅读时间增加,并减少基于单词的平均凝视时间和再注视概率。实验二采用与实验一相同的处理方式,以不提供词边界的双字为单元掩蔽注视点右侧文字,结果发现掩蔽条件对阅读的影响程度甚于实验一,条件2基于词的平均凝视时间显著高于控制条件。综合两个实验的结果可见,中文读者能够切分出注视点右侧的第一个词汇,并以词为单元识别词n和词n+1处的汉字,在注视词n的时间内可加工到词n+2处的文字。     

Parental Emotion Coaching: Associations With Self-Regulation in Aggressive/Rejected and Low Aggressive/Popular Children

This study investigated associations between maternal and paternal emotion coaching and the self-regulation skills of kindergarten and first-grade children. Participants were 54 children categorized as either aggressive/rejected or low aggressive/popular by peer reports. Findings indicated a statistical trend for fathers of low aggressive/popular children to engage in more emotion coaching than fathers of aggressive/rejected children. Paternal emotion coaching accounted for significant variance in children's regulation of attention. Maternal emotion coaching moderated the relation between children's status and regulation of emotion. Findings suggest that interventions focused on parental emotion coaching may prove beneficial for increasing the self-regulation and attention skills of children with social and conduct problems.     

Domain‐General and Domain‐Specific Creative‐Thinking Tests: Effects of Gender and Item Content on Test Performance

The study examined the effects of gender and item content of domain‐general and domain‐specific creative‐thinking tests on four subscale scores of creative‐thinking (fluency, flexibility, originality, and elaboration). Chinese tenth‐grade students (234 males and 244 females) participated in the study. Domain‐general creative thinking was measured by using two domain‐independent items—box and newspaper. Domain‐specific creative thinking was measured in the domain of history by two history‐specific items—school uniform and health food—that were part of lessons in modern Chinese history. Domain‐general creative‐thinking scores were not different across gender in any of the four subscales. In domain‐specific creative thinking, female students produced more responses (fluency) and more categories of ideas (flexibility), and more detailed answers (elaboration) on both items than did males. Gender difference was not found in originality. Item effects were significant in both general and specific creative‐thinking scores, with higher fluency, flexibility, and elaboration for the newspaper than the box item, and higher fluency, flexibility, originality, and elaboration for the school uniform than the health food item. The findings on both gender and item effects support the contention that personal interest and life experience influence the generation of creative solutions. The finding that gender did not differ in domain‐general creative‐thinking was expected, as the two general items (box and newspaper) are experienced similarly by both genders. As most of the creative‐thinking tests are influenced by individuals' experience beyond creative‐thinking ability, judicial evaluation and use of creative‐thinking scores are underscored.     

Disentangling the Effects of Applicant Defensive Impression Management Tactics in Job Interviews

This study explores (1) the effects that three kinds of applicant defensive impression management (IM) tactics (apologies, justifications, and excuses) have on interviewer evaluation and (2) the moderating effects that two types of interviewer negative concerns (competence‐related and integrity‐related concerns) have on the aforementioned relationship. Two hundred and one managers from Taiwan participated in this study by watching a simulated interview. Compared with the control group, applicants using defensive IM tactics received higher interviewer ratings when negative concerns surfaced. Moreover, the type of interviewer negative concern moderated the effects of defensive IM tactics. All three tactics had similar effects on interviewer evaluation when the concern was competence related. Apology was, however, the most effective tactic when the concern was integrity related.

Definition of Financial Abuse: A Culture-Centered Construct among Korean Elders

One of the critical issues in addressing financial abuse in Korea is the absence of an appropriate definition voiced by the elderly. This study is designed to explore how Korean elders define financial abuse in given social and cultural contexts. Face-to-face, in-depth interviews were conducted with 124 elders, aged 60 to 79, residing in Korea. The results of qualitative data analysis using grounded theory revealed that a vast majorty of Korean elderly respondents defined financial abuse as lack of provision of financial support to elder parents, and a small portion of respondents defined it as financial exploitation by adult children. The definition of financial abuse reflects cultural beliefs based on filial piety about financial expectations within the parent–child relationship. Education on financial abuse for both elders and their adult children and establishment of income support programs are urgently needed efforts to increase the financial well-being of elderly Koreans.     

小学五年级儿童执行功能特点研究

本研究旨在通过对小学五年级儿童的执行功能进行测试和训练,探究小学五年级学生注意转换能力、记忆刷新能力和抑制优势反应能力三种执行功能的特点.研究表明小学五年级儿童执行功能中的这三种能力是相互独立的,且具有不平衡性和可发展性特点.结果表明 ,小学五年级学生的注意转换能力明显低于大学生,同时也比成人平均水平低;记忆刷新能力优于成人平均水平;而抑制优势反应能力已基本达到成人平均水平.     

不同自尊水平者的注意偏向

本研究分别从外显自尊和内隐自尊角度出发, 以大学生情绪面孔(高兴, 中性, 愤怒)图片为实验材料, 采用“空间线索任务”实验范式, 探讨不同自尊水平个体注意偏向的特点及其内在机制。结果表明, 在无效线索条件下, 低外显自尊个体对以愤怒为提示线索的靶刺激的反应时显著长于高兴和中性, 说明低外显自尊个体对负性情绪信息(愤怒)的注意偏向是一种注意的解脱困难; 高内隐自尊个体在无效线索条件下, 对以高兴和愤怒为提示线索的靶刺激的反应时显著长于中性, 说明高内隐自尊个体更易受到情绪性信息(愤怒和高兴)的吸引, 是一种选择性的注意维持倾向, 表现为注意的解脱困难。     

反馈在自我调节学习中的作用

反馈一直是学习研究领域中非常重要的主题之一。随着学习理论的发展,人们对反馈的研究逐渐深化与综合化。一方面从自我调节学习的过程模型出发,考察了反馈的不同因素对自我调节学习过程和结果的作用;另一方面以自我调节学习的社会认知理论为框架,探讨了情绪、学业成绩等个体因素以及目标定向、任务难度等情境因素对反馈作用的交互影响。未来研究需要进一步探讨内部反馈信息以及学习者元认知监控的调节作用,结合个体和情境因素揭示反馈对自我调节学习的整体动态过程的影响,并设计出促进学习和教学实践的反馈方案。
