气质性乐观与心理健康关系的元分析

运用元分析方法分别探讨了气质性乐观与心理健康的积极指标和消极指标的关系。共有106项研究满足了元分析的标准,涉及气质性乐观与心理健康积极指标的研究有70项,包括83个独立样本(N=30627);涉及气质性乐观与心理健康消极指标的研究有75项,包括105个独立样本(N=39064)。元分析结果发现:(1)整体上气质性乐观与心理健康积极指标有显著正相关(r=0.41),与心理健康消极指标有显著负相关(r=-0.41)。(2)气质性乐观与不同心理健康指标的相关有显著差异,积极指标中,与自尊的相关最高;消极指标中,与抑郁的相关最高。(3)气质性乐观测量工具的差异对其与心理健康的关系没有显著影响。(4)不同年龄阶段群体中气质性乐观与心理健康的关系没有显著差异。(5)文化背景差异对两者的关系有显著影响,西方文化中气质性乐观与心理健康的相关高于东方文化中的相关。     

略谈道家内功的特点与养生效用

内功与外功相对,是以侧重于协调和增强人体精气神为目的的各种运动方式的总称;外功则是侧重锻炼人体肌肉、力量和速度为目的的运动方式的总称.内功又分动功和静功.动功,传统上包括导引、按(足乔),是行气、意念和肢体运动相结合的运动方式,它以有明显的肢体运动为特征.     

Analysis of RT distributions in the remember—know paradigm

Do remembering and knowing differ qualitatively (reflecting distinct underlying processes) or quantitatively (reflecting different levels of strength)? Broadly speaking, models of remember—know judgments based on these alternatives have been tested by examining the proportion of remember and know responses that are made across conditions or levels of confidence. Here, we consider reaction time (RT) data. We replicate Dewhurst and Conway’s (1994) observation that old judgments followed by remember responses are faster, on average, than those followed by know decisions, but show that this effect is largely due to differing distributions of remember and know responses across confidence levels. In addition, fits of ex-Gaussian distributions of hit RTs followed by either remember or know judgments yield similar parameter values when confidence level is controlled. Thus, these RT data do not provide strong support for the idea that remembering and knowing depend on different processes.     

学前儿童的现实性监测对易受暗示性的预测

对学前儿童的现实性监测与易受暗示性发展之间的关系进行了考察.结果表明,在控制了年龄、对事件的初始编码和提取能力后,现实性监测能力可以显著地预测记忆的易受暗示性.那些现实性监测能力较低的儿童更容易接受误信息,相反,那些现实性监测能力较强的儿童,更能抵制误信息的干扰.     

Transient attention does increase perceived contrast of suprathreshold stimuli: a reply to Prinzmetal, Long, and Leonhardt (2008)

Carrasco, Ling, and Read (2004) showed that transient attention increases perceived contrast. However, Prinzmetal, Long, and Leonhardt (2008) suggest that for targets of low visibility, observers may bias their response toward the cued location, and they propose a cue-bias explanation for our previous results. Our response is threefold. First, we outline several key methodological differences between the studies that could account for the different results. We conclude that the cue-bias hypothesis is a plausible explanation for Prinzmetal et al.'s (2008) results, given the characteristics of their stimuli, but not for the studies by Carrasco and colleagues, in which the stimuli were suprathreshold (Carrasco, Ling, & Read, 2004; Fuller, Rodriguez, & Carrasco, 2008; Ling & Carrasco, 2007). Second, we conduct a study to show that the stimuli used in our previous studies are not near-threshold, but suprathreshold (Experiment 1, Phase 1). Furthermore, we found an increase in apparent contrast for a high-contrast stimulus when it was precued, but not when it was postcued, providing more evidence against a cue-bias hypothesis (Experiment 1, Phase 2). We also show that the visibility of the stimuli in Prinzmetal et al. (2008) was much lower than that of Carrasco, Ling, and Read, rendering their stimuli susceptible to their cue-bias explanation (Experiment 2). Third, we present a comprehensive summary of all the control conditions used in different labs that have ruled out a cue bias explanation of the appearance studies. We conclude that a cue-bias explanation may operate with near-threshold and low-visibility stimuli, as was the case in Prinzmetal et al. (2008), but that such an explanation has no bearing on studies with suprathreshold stimuli. Consistent with our previous studies, the present data support the claim that attention does alter the contrast appearance of suprathreshold stimuli.     

企业员工心理契约的结构维度

用所研制的心理契约问卷,先后通过6家和4家两个企业员工样本共1088名被试的调查,对心理契约结构维度进行探讨。探索性因素分析结果表明,心理契约组织责任和员工责任均由现实责任和发展责任两个因素构成。两因素结构的结果在验证性因素分析中得到了验证。最后对心理契约结构维度的构成、内容和含义及其与西方研究结果的异同进行了讨论。     

分布式群体在动态系统控制决策中的内隐学习

采用计算机网络模拟技术,考察分布式群体在动态系统控制决策过程中对系统规则的内隐学习效应及其迁移。结果表明,在决策者的显性规则知识量极少且没有增加的情况下,决策绩效随决策进程适应性提高。决策者所能报告的规则知识量与决策绩效的相关也不显著。同时,当决策任务目标转换时,决策的高绩效得以维持。这表明群体决策者能对动态系统规则进行内隐学习,且能正迁移到类似的决策情景中。研究进一步指出,群体决策行为的动态适应与内隐过程有关。     

自我知觉积极偏向的理论解释和意义分析

许多研究者注意到了人在进行自我知觉时的积极偏向,并提出各种观点对其进行解释和论证;许多实证研究也从不同侧面揭示了这种乐观偏向的适应意义。本文对相关内容进行了综合和梳理,介绍了自我增强的动机、自尊的需要和实现趋向等理论观点;并概括出这一积极偏向在提高行为动机和成就表现、消除不良情绪以及增进身心健康和社会适应等方面所具有的积极作用。     

关于小学教师对学生课堂参与的内隐观的研究

本研究通过课堂观察和结构化访谈,从三个侧面,即：教师判断学生参与的标准、对学生参与特点的描述、对参与功能的界定,考察了49名小学教师对学生课堂参与的内隐认识。研究表明,教师：1)重视师生交往中学生的参与,忽视学生与同学间的交往和学生独立活动时的表现;2)最关注学生在行动上的参与,其次是学生思维的投入,对学生情绪的投入是比较忽视的;3)特别注重参与促进学生认知能力发展的功能。     

管理者责任心和工作绩效关系的研究

本研究旨在探讨管理者责任心和工作绩效间的关系。通过对236名管理者施测自编的管理者责任心问卷和修订的工作绩效问卷,结果发现：(1)服务取向和可依赖性对人际促进的预测效果较好;(2)服务取向、个人品德和有计划性对任务绩效的预测效果较好;（3）个人品德、有计划性和成就取向对工作奉献的预测效果较好;(4)管理者责任心对关系绩效的预测高于对任务绩效的预测。
