Types of Leaders Across the Organizational Hierarchy: A Person-Centered Approach

Leadership pipeline research typically has taken a “skill-centered” approach to describe the changing skill requirements across management positions. However, the current study advances previous research by taking a “person-centered” approach to investigate the prevalence of different leader types along the organizational hierarchy. Based on an inverse principle components analysis, this study identified three unique patterns of skill configuration. We labeled the three leader types: (a) Driven Experts, (b) Principled Partners, and (c) Charismatic Advocates. It was found that the prevalence of one type (Principled Partners) decreased across organizational levels, whereas the other two types (Driven Experts and Charismatic Advocates) increased in the prevalence from the low to high management levels. The implications of the findings on leadership development are discussed.     

Local Dynamic Stability of the Locomotion of Lower Extremity Joints and Trunk During Backward Upslope Walking

Backward slope walking was considered as a practical rehabilitation and training skill. However, its gait stability has been hardly studied, resulting in its limited application as a rehabilitation tool. In this study, the effect of walking direction and slope grade were investigated on the local dynamic stability of the motion of lower extremity joints and trunk segment during backward and forward upslope walking (BUW/FUW). The local divergence exponents (λ_S) of 16 adults were calculated during their BUW and FUW at grades of 0%, 5%, 10%, and 15%. Mean standard deviation over strides (MeanSD) was analyzed as their gait variability. Backward walking showed larger λ_S for the abduction-adduction and rotational angles of knee and ankle on inclined surface than forward walking, while λ_S for hip flexion-extension angle at steeper grades was opposite. No grade effect for any joint existed during BUW, while λ_S increased with the increasing grade during FUW. As to the trunk, walking direction did little impact on λ_S. Still, significant larger λ_S for its medial-lateral and vertical motion were found at the steeper grades during both FUW and BUW. Results indicate that during BUW, the backward direction may influence the stability of joint motions, while the trunk stability was challenged by the increasing grades. Therefore, BUW may be a training tool for the stability of both upper and lower body motion during gait.     

当代大学生职业兴趣的结构与测量

该研究考察了我国当代大学生职业兴趣的结构,并编制出相应的测量工具.首先通过开放式问卷调查、文献调研,以及对已有测评工具中条目的整理,构建出职业兴趣描述库,再以此为基础编制自陈式职业兴趣调查表,对大学生的职业兴趣结构进行初步探索,得出九个维度,分别命名为研究型、艺术型、展示型、社会型、冒险型、企业型、常规型、现实型和生态型.其次通过验证性因素分析方法检验测验的构想效度,结果发现各指标拟合良好.此外,实证数据也表明测验具有良好的同质性信度和重测信度.研究结果证明大学生职业兴趣调查表具有较好的心理测量学品质,可应用于实践领域.     

表现性测验在能力评价中的应用

相对传统的纸笔测验形式,表现性测验的突出特点是任务的真实性水平较高。表现性测验是一种认知导向的测验。在国外教育、医学、心理咨询与治疗等领域的能力评价中,一系列表现性测验已被开发出来并用于实践,获得了较好的心理测量学指标。表现性测验可用于国内学生、教师的能力评价,辅助人才选拔以及相关职业资格认证的实践。表现性测验开发过程中若合理应用概化理论、项目反应理论等现代测量理论,对于提高测验信度和效度都有一定积极意义。     

Children's memory for the times of events from the past years

This study tested 8–12‐year‐olds' ability to localize in time parent‐reported events from four time intervals ranging from 6 months to 4 years ago. Memory for content was very accurate, and children's time estimates showed substantial agreement with the times provided by their parents. Accuracy of year judgments declined with retention interval, with the greatest change occurring between the 1–2‐year and 2–3‐year intervals. Season, month and time of day accuracy were much more stable over time. There were significant improvements with age in performance on measures of conventional time knowledge, and this performance was correlated with the accuracy of time estimates on the long time scales, controlling for age and general cognitive ability.

Going my way? The benefits of travelling in the same direction

Couples' marital satisfaction can depend on whether they commute to work in the same or different directions. Two surveys, conducted in the United States and Hong Kong, showed that partners' satisfaction with their relationship was greater when they traveled to work in the same direction than when they traveled in different directions. This was true regardless of whether the partners left for work at the same or different times. A controlled laboratory study eliminated alternative interpretations of the survey findings, showing that even randomly paired participants reported greater attraction to one another when they walked to an experimental task in the same direction rather than in different directions.     

不同类型音乐对悲伤情绪舒缓作用的EEG研究

该研究采用EEG法探究音乐对悲伤情绪舒缓作用。选取中国古典、流行、摇滚及班得瑞音乐及悲伤影片。播放影片诱发悲伤情绪后,用音乐进行舒缓,同步采集脑电,分析得脑电功率谱(PS)及重心频率(GF)。结果表明,影片显著降低了GF及α频段PS;古典音乐GF最高,且诱发的α段PS最高,摇滚乐最低;脑对音乐加工的性别差异显著,半球差异不显著;主观体验悲伤度与α波PS显著负相关。所选音乐均具情绪舒缓作用,中国古典音乐最佳;α波PS,可作为反映悲伤-快乐情绪体验变化的脑电指标。     

新一代测验理论-认知诊断理论的源起与特征

认知诊断理论被视为新一代测验理论的核心,是认知心理学与现代测量学相结合的产物。对认知诊断的研究已成为当前国外心理学研究的一个重要热点,并引起国内学者的广泛关注。本文从认知诊断的源起、概念、特征,及研究的基础、框架、意义和难点等七个方面对认知诊断的理论与技术作了一个简要述评,以期推进我国心理学界认知诊断的研究工作。     

5～9岁儿童对心理过程差异的理解

对心理过程差异的理解是学龄后儿童心理理论发展的一部分。本文主要探讨5-9岁儿童对心理过程差异的理解,即理解两个体在看到同样的物体时思维过程是否相同。采用“思想泡泡”的方法给5岁、7岁、9岁各20名儿童讲述故事,考察故事中人物背景知识的有无、对象的不同(自我-他人/他人-他人)及对象间关系的不同(朋友/陌生人)对儿童判断心理过程差异的影响。结果发现,有无背景信息对儿童理解心理过程差异有显著影响,而故事中对象不同及对象之间关系的不同对儿童理解心理过程差异无显著影响。同时还发现,随着年龄的增长,儿童逐渐意识到两个体的思维过程是不同的且能提供比较充分的解释,对心理过程差异的理解使学龄后儿童对个体独特性有更深的了解。     

澳门和东北地区夫妻沟通模式与婚姻满意度研究

采用问卷调查法对澳门（118对）和东北地区（266对）夫妻进行研究,以检验两地夫妻沟通模式的差异,及其对婚姻满意度的主客体效应。结果发现：澳门夫妻双方回避沟通显著少于东北夫妻;两地夫妻报告的妻子要求/丈夫回避行为多于丈夫要求/妻子回避行为;建设性沟通对两地夫妻婚姻满意度正向预测力最强;要求/回避沟通只对澳门夫妻的婚姻满意度有负向预测力。两地妻子的建设性沟通都能显著正向预测丈夫的婚姻满意度,而只有东北地区丈夫的建设性沟通能正向预测妻子婚姻满意度。
