基于不对称区间估计的有调节的中介模型检验

有调节的中介模型是中介过程受到调节变量影响的模型。评介了基于Bootstrap不对称置信区间和贝叶斯不对称可靠区间进行有调节的中介模型检验的3种方法, 包括亚组分析法、差异分析法和系数乘积法。模拟研究发现, 偏差校正的百分位Bootstrap置信区间和无先验信息的贝叶斯可靠区间在有调节的中介模型检验中表现相当, 都优于百分位Bootstrap置信区间的表现。建议使用系数乘积法进行第一阶段或第二阶段被调节的中介模型检验, 使用差异分析法进行两阶段被调节的中介模型检验, 并用一个实际例子演示如何用不对称区间估计检验有调节的中介模型。随后评述了3种有调节的中介模型检验方法在国内心理学的应用现状, 并展望了检验的拓展方向。     

中介效应的检验方法和效果量测量:回顾与展望

通过中介效应检验方法之间的比较和效果量指标之间的比较,建议放弃将总效应c显著作为中介效应检验的前提条件,放弃基于直接效应c'显著性的完全和部分中介的提法,推荐使用偏差校正的百分位Bootstrap法直接对中介效应ab进行检验,使用κ²、R_med²等中介效果量指标并报告效果量的置信区间。作为示例,用R软件的MBESS软件包对某消防员饮食健康调查进行了中介效应检验和效果量测量。随后展望了中介效应检验方法和效果量测量的拓展方向。     

趋近和回避动机的区分及其对心理病理学的影响

趋近和回避是动机的两种最基本形式, 反映着个体与环境的相互作用方式, 是个体适应环境的核心机能。回避动机保证了个体的生存, 趋近动机则促进个体的成长。两类动机系统在前额叶皮层呈不对称偏侧化分布, 趋近动机与左侧额叶皮层激活相连, 回避动机与右侧额叶皮层激活相连。Youngstorm 和Izard等认为两类动机系统失调可能与一系列的情绪和行为问题有关, 如躁狂、抑郁、焦虑和儿童多动症等。这一观点已得到一些相关研究和临床研究证实。建议未来研究关注趋近-回避动机区分与情绪和认知功能研究的融合, 进一步检验趋近-回避动机系统失调模型, 并加强趋近和回避动机系统的可塑性研究。     

基于日常经验取向的责任心理结构研究

基于日常经验取向,运用理论建构和深度访谈的方法,研究责任的心理结构以及责任情境的认知特征。对207名被试访谈研究的结果表明：（1）责任是人们频繁感知和体验到的一种社会心理现象;（2）人们体察到的责任情境,在职业活动和个人生活领域存在类型上的差异;（3）在职业活动中,人们更倾向于将责任归因于他人,而在个人生活中更倾向于归因于自己;（4）人们对责任情境性质的判定与责任事件最终能否达到预期目标有关;（5）责任心理结构共由情境起因、自我效能、成就感、内外动机等20个核心要素构成;（6）责任心理结构是一个由责任认知、责任情感和责任行为三者构成的一元单向决定模式。     

童年晚期亲社会行为与儿童的心理社会适应

对2097名六年级儿童(平均年龄12.27岁, 男生1093名)的亲社会行为以及多种心理社会适应指标进行测量, 主要运用个体定向的方法考察童年晚期亲社会行为与儿童心理社会适应之间的关系。结果发现:(1)亲社会行为与孤独感、攻击等不良适应呈中等程度负相关, 与同伴接纳、社交自我概念等积极适应呈中等程度正相关;(2)童年晚期儿童的心理社会适应表现为内化问题、外化问题、同伴拒绝与正常发展4种模式;(3)个体亲社会行为水平越高, 越可能属于正常发展组, 越不可能属于不良适应组;在各种不良适应组中, 个体亲社会行为水平越高, 更可能属于内化问题组, 而非外化问题和同伴拒绝组;(4)高亲社会组的儿童有6.8%存在内化问题;低亲社会组的儿童有50.2%适应良好;与普通儿童相比, 低亲社会组的儿童表现出更多的适应不良。     

无意识情绪研究的新方向

首先介绍关于“无意识情绪”的两种概念。接着介绍可较好地对该两类无意识情绪概念进行整合的无意识情绪信息加工模型--Wiens模型(Wiens & Öhman, 2007), 分析了Wiens模型中“刺激聚焦途径”与“体验聚焦途径”两条途径下的无意识情绪的基本观点、相关实证研究、分别面临的研究难题或受到的质疑, 及不同途径下无意识情绪的本质。在此基础上指出, 传统情绪理论下情绪的意识属性或可与Wiens模型中体验聚焦途径下情绪的无意识属性互为补充, 相辅相成; 无意识情绪研究的新方向是体验聚焦途径。最后, 对未来研究提出了展望。     

METANEXUS 2007: THE CHALLENGE AHEAD

This essay is William Grassie's valedictory remarks at the Metanexus Institute's 2007 Annual Conference. Grassie asks what is wrong with religion, what is wrong with science, and why the constructive engagement of the two holds the key to setting things right. He cites Sir John Templeton and others to make his case and proposes a new curriculum for general science education that uses the history of nature as a mnemonic and context for promoting better science literacy and the incorporation of science into our cultural traditions.     

The Acceptability and the Tolerability of Societal Risks: A Capabilities-based Approach

In this paper, we present a Capabilities-based Approach to the acceptability and the tolerability of risks posed by natural and man-made hazards. We argue that judgments about the acceptability and/or tolerability of such risks should be based on an evaluation of the likely societal impact of potential hazards, defined in terms of the expected changes in the capabilities of individuals. Capabilities refer to the functionings, or valuable doings and beings, individuals are able to achieve given available personal, material, and social resources. The likely impact of a hazard on individuals' capabilities should, we argue, be compared against two separate thresholds. The first threshold specifies the minimum level of capabilities attainment that is acceptable in principle for individuals to have in the aftermath of a hazard over any period of time. This threshold captures the level that individuals' capabilities ideally should not fall below. A risk is acceptable if the probability that the attained capabilities will be less than the acceptable level is sufficiently small. In practice, it can be tolerable for some individuals to temporarily fall below the acceptable threshold, provided this situation of lower capabilities attainment is temporary, reversible, and the probability that capabilities will fall below a tolerability threshold is sufficiently small. This second, tolerable threshold delimits an absolute minimum level of capabilities attainment below which no individual in a society should ever fall, regardless of whether that level of capabilities attainment is temporary or reversible. In this paper, we describe and justify this Capabilities-based Approach to the acceptability and tolerability of risks. We argue that the proposed theoretical framework avoids the limitations in current approaches to acceptable risk. The proposed approach focuses the attention of risk analysts directly on what should be our primary concern when judging the acceptability and the tolerability of risks, namely, how risks impact the well-being of individuals in a society. Also, our Capabilities-based Approach offers a transparent, easily communicable way for determining the acceptability and the tolerability of risks.     

Pastoral Counseling of Older Adults: Toward a Short-term Integrative Approach

A rapidly aging population with its mental health care needs presents an enormous challenge in the current mental health field. In light of this, pastoral counselors will have an increasingly important role to play in the care of older adults because of their strategic position in the community and their competence in dealing with religious/spiritual issues particularly salient in old age. This article proposes a short-term integrative approach to enable pastoral counselors to effectively and efficiently meet the mental health care needs of the elderly.
