An observational measure of children's behavioural style: Evidence supporting a multi‐method approach to studying temperament

This study demonstrates the potential utility of the Behavioural Style Observational System (BSOS) as a new observational measure of children's behavioural style. The BSOS is an objective, short and easy to use measure that can be readily adapted to a variety of home and laboratory situations. In the present study, 160 mother–child dyads from the Concordia Longitudinal Risk Project (CLRP) were observed during an 11‐min behavioural sample. Videotaped interactions were coded using the BSOS for children's mood, activity level, vocal reactivity, approach to toys, mood consistency and adaptability. Comparisons between the BSOS observational ratings and mothers' ratings of the child on the EAS Temperament Survey (EAS) provided support for modest congruence between these two measurement systems, and revealed a differential predictive pattern of children's functioning. Specifically, the observation‐based BSOS predicted children's cognitive performance and adaptive behaviour during testing, whereas the mother‐rated EAS predicted maternal ratings of children's internalizing and externalizing behaviour problems. Both measures were found to independently predict mothers' ratings of parenting stress. Overall, the findings imply that neither observational measures nor maternal ratings alone are sufficient to understand children's behavioural style, and that comprehensive evaluations of children's temperament should optimally include both types of measures.

共同方法偏差的统计检验与控制方法

共同方法偏差是心理学研究中一个越来越被关注的课题,但国内心理学界对其的介绍、研究还比较少,导致研究中对共同方法偏差的控制还有所欠缺。共同方法偏差的控制方法分为程序控制和统计控制,该文介绍了共同方法偏差的多种统计控制法,如因素分析法、偏相关法、潜在的误差变量控制法、结构方程模型法等,分析了其各自的优缺点,并提出了如何选择采用这些方法的建议.     

翻转教学法对高中生认知负荷及学习成绩的影响

采用不等组实验组、控制组前测后测的准实验设计,探讨了翻转课堂背景下翻转教学法对高中生认知负荷及学习成绩的影响。结果发现：（1）翻转教学法能有效降低高中生的内在认知负荷,提高其学习成绩与学习效率;（2）翻转课堂背景下,高中生的认知负荷存在知识反转效应,即高成绩者的收益低于低成绩者。结果提示,翻转课堂取得优异学习效果的心理机制在于通过有效降低学习者的内在认知负荷而影响其学习成绩;同时,翻转教学法的运用过程中须考虑学习者认知负荷的变化及学习效率,其对所有的学习者不是同等有效的。     

三类多层中介效应分析方法比较

比较了贝叶斯法、Monte Carlo法和参数Bootstrap法在2-1-1多层中介分析中的表现。结果发现：1)有先验信息的贝叶斯法的中介效应点估计和区间估计都最准确;2)无先验信息的贝叶斯法、Monte Carlo法、偏差校正和未校正的参数Bootstrap法的中介效应点估计和区间估计表现相当,但Monte Carlo法在第Ⅰ类错误率和区间宽度指标上表现略优于其他三种方法,偏差校正的Bootstrap法在统计检验力上表现略优于其他三种方法,但在第Ⅰ类错误率上表现最差;结果表明,当有先验信息时,推荐使用贝叶斯法;当先验信息不可得时,推荐使用Monte Carlo法。     

高中生学校生活中的情感体验:基于日重现法的研究

采用日重现法对133名高中生学校生活中的情感体验进行实描研究,考察了高中生在学校生活中的活动、活动场所、互动对象及与之相应的各种情感体验的日波动模式。结果如下:(1)高中生在一天中的绝大多数活动、场所以及人际互动中均表现为积极情感的体验强度大于消极情感;(2)大部分积极情感以及疲劳的体验强度都表现为在晚睡前达到一天中的最高点,大部分消极情感体验都在该时段降至一天中的最低点;(3)全天都体验到较强烈的胜任感,中午的体验强度最大,早晨的体验强度最低。     

日常情绪的社会分享对情绪的影响

日常情绪的社会分享对情绪有怎样的影响,以往研究结论并不一致。本研究从社会分享的信息层面和感受层面以及当天情绪体验等方面收集了47名大学生和研究生被试7天共314份日志记录,使用多层线性模型进行分析,结果表明：（1）积极分享和消极分享都能显著正向预测当日的积极情绪,但是不能预测当日的消极情绪;（2）感受的分享（包括积极感受和消极感受）显著正向预测当日的积极情绪,信息的分享不能预测当日的积极情绪;（3）性别、抑郁水平和消极事件分享倾向会影响分享消极感受的水平对积极情绪的正向预测。结论：无论是积极感受分享还是消极感受分享都能提升积极情绪,但是不能改善负性情绪;消极感受分享对积极情绪的提升作用存在个体差异。     

Response Selection Contributes to the Preparation Cost for Bimanual Asymmetric Movements

Movement preparation of bimanual asymmetric movements takes more time than bimanual symmetric movements in choice reaction-time conditions. This bimanual asymmetric cost may be caused by increased processing demands on any stage of movement preparation. The authors tested the contributions of each stage of movement preparation to the asymmetric cost by using the additive factors method. This involved altering the stimulus contrast, response compatibility, and response complexity. These manipulations changed the processing demands on stimulus identification, response selection, and response programming, respectively. Any manipulation with a larger reaction time cost than control suggests that stage contributes to the bimanual asymmetric cost. The bimanual asymmetric cost was larger for incompatible stimuli, which supports that response selection contributes to the bimanual asymmetric cost.     

加强住院医师临床思维能力培养的探讨

良好的临床思维能力,是住院医师能否成为合格和高水平医生的关键。对住院医师临床思维能力的培养必须明确临床思维的哲学本质和组成的关键要素,并结合住院医师的特点去培养。要注重基本知识、基本理论和基本技能训练,把握正确的恩维程序,运用哲学思想,并以学科综合为中心。     

基于认知设计系统的几何类比推理测验的编制及认知模型分析

认知诊断是一种新的测量范式。本研究首先根据Mulholland,Pellegrino＆Glaser和Whitely＆Schneider关于类比推理的研究结果,采用认知设计系统编制了几何类比推理测试题,并对所编制的测试题的质量进行验证,然后采用口语报告法分析解决几何类比推理所涉及的认知模型,结果表明：1）编制的几何类比推理测试题的质量比较好;2）学生解决类比推理所涉及的认知属性主要为置换、翻转、旋转、数量、大小、颜色与条纹和形状。
