Genetic and Environmental Pathways Underlying Personality Traits and Perceived Stress: Concurrent and Longitudinal Twin Studies

The present study examined the genetic and environmental etiology underlying the Big Five personality traits and perceived stress, concurrently and longitudinally. In study 1, we used the twin sample from the National Longitudinal Study of Adolescent to Adult Health (Add Health IV) data. The results indicated that about 70% of the association between the Big Five personality traits and perceived stress was due to genetic influences. In study 2, we used the twin sample from the Midlife in the United States Survey (MIDUS I and II) to examine the genetic and environmental influences underlying the longitudinal relations between the Big Five personality traits and perceived stress. The results suggested that continuity in perceived stress was primarily accounted for by genetic influences, and changes in perceived stress were mainly due to nonshared environmental influences. The continuity in the association between the five personality traits and perceived stress was largely accounted for by genetic factors, and nonshared environmental factors made greater contributions to changes in the association between personality traits and perceived stress. Among the Big Five personality traits, the genetic components in conscientiousness and neuroticism made substantial contributions to the genetic link between personality traits and perceived stress across both studies.

流动性、教育安置方式和心理弹性对流动儿童孤独感的影响:一项追踪研究

采用潜变量增长模型对426名流动儿童进行四次追踪测查,旨在考察流动儿童孤独感的变化趋势,探索不同流动性和教育安置方式的流动儿童孤独感变化的差异性以及心理弹性对孤独感变化的促进性作用。结果发现：（1）流动儿童的孤独感呈线性下降趋势;（2）打工子弟学校流动儿童的孤独感起始水平显著高于公立学校流动儿童;流动性高的儿童的孤独感起始水平高于流动性低的儿童,但流动性和教育安置方式对孤独感的发展趋势没有显著预测作用;（3）对于流动儿童来说,较高的心理弹性水平不仅能显著预测更低的孤独感起始水平,同时也能显著预测更快的孤独感的下降速率。本研究启示,增加进入公立学校学习的机会、降低流动频率和提升心理弹性对降低流动儿童的孤独感水平具有重要的意义。     

初中生应对方式、压力对社会适应的影响:纵向中介模型

青春期的适应问题及其影响因素历来是研究者关注的焦点。本研究对369名初中生从初一到初三的应对方式、压力、社会适应进行了四次调查,通过纵向中介模型考察应对方式、压力对社会适应的影响。结果表明：初一时期的积极应对方式能够直接提高初三时期的积极适应水平,直接降低消极适应水平;初一时期的消极应对方式会通过提高后期的压力间接提高初三时期的消极适应水平。     

青少年友谊关系质量与社交焦虑的相互影响:一项交叉滞后分析

采用问卷法和追踪设计,通过交叉滞后回归分析,考察初中三年期间698名青少年的友谊关系质量与社交焦虑的相互影响及其动态变化。结果发现,初二到初三期间,青少年友谊关系质量的喜爱-满意维度显著负向预测社交焦虑;初中三年期间,青少年社交焦虑显著负向预测友谊关系质量的喜爱-满意维度;但友谊关系质量的冲突维度与社交焦虑的相互预测作用不显著。这些结果表明,青少年友谊关系的喜爱-满意维度与其社交焦虑之间存在相互影响,而且该相互作用存在一定程度的动态变化。     

母亲元情绪理念与学前儿童社会适应的相互作用关系

采用追踪设计对438名学前儿童母亲进行问卷调查研究,主要探讨了母亲元情绪理念与学前儿童社会适应的相互作用关系。交叉滞后分析结果表明：（1）相邻两次测量的母亲各元情绪理念之间,社会适应各指标之间均具有中等程度的稳定性;（2）同一时间点的母亲各元情绪理念与儿童社会适应各指标之间均显著相关;（3）母亲元情绪理念与儿童社会适应之间部分存在着相互作用关系：控制了变量自身的连续性后,前测的母亲情绪教导显著正向预测后测的儿童敏感合作;前测的母亲情绪不干涉显著正向预测后测的儿童愤怒攻击、焦虑退缩行为;反过来,前测的儿童敏感合作能正向预测后测的母亲情绪教导,显著负向预测情绪不干涉、情绪摒除和情绪紊乱;前测的焦虑退缩能显著正向预测后测的母亲情绪摒除和情绪紊乱。     

Capturing the interplay among within- and between-person processes using multilevel modeling techniques

Multilevel modeling is an excellent way to analyze nested or clustered data of the type commonly collected through investigations into the linkages between psychological functioning and relationship processes. This article describes two especially relevant applications of multilevel modeling. The first application, growth curve analysis, is already familiar to many researchers and involves modeling individuals’ change trajectories over time and relating the derived change parameters to person-level characteristics or phenomena. The purpose of this paper is to emphasize a second application, multilevel process analysis, which involves modeling within-subject characteristics other than change over a representation of time. Multilevel analysis of within-subject processes is particularly well-suited for hypotheses common to clinical psychology investigations, yet has received substantially less attention in the literature than its growth curve counterpart. Types of research questions and methodologies that can be addressed within the multilevel process analysis framework are described. Finally, aspects of multilevel process analysis are demonstrated with daily diary data collected from wives who reported on their marital happiness and depressed mood for 3 weeks.     

Lessons Learned from the Parents Matter! Program

We present a discussion of some of the lessons the investigators learned during the development and implementation phases of the Parents Matter! Program (PMP). Lessons were learned that are relevant to various groups involved in large scale, multi-site, community-based intervention studies: investigators, community leaders, community members, project staff, and participants. Specific lessons learned include: (1) forge collaboration early: (2) maintain communication; (3) clearly delineate policies and procedures; and (4) develop proactive strategies. We also include a list of important questions to consider when contemplating similar projects.     

Self-Discrepancy and Mental Health in Older Women with Chronic Illnesses

Self-discrepancy was investigated as a self-enhancing mechanism by which older women maintain their mental health and psychological well-being while coping with declines in physical health. In this 6-year longitudinal study, the mediating and moderating effects of self-discrepancy on mental health outcomes in older women with chronic health problems were tested. Participants were 103 community-dwelling older women who completed multiple, self-report measures of physical and mental health and self-discrepancy. There was a decline in physical health over time but an improvement in self-discrepancies. Low self-discrepancy (i.e., little discrepancy between the actual and ideal self) mediated and moderated the effects of physical health decline on mental health and psychological well-being. Thus, self-discrepancy appears to play a significant role in maintaining mental health in the face of declining physical health in older women.     

幽默平面广告的适用性研究

为了探讨哪一类别商品的平面广告更适合于采用幽默的诉求方式,研究随机选取160大学生为被试,以16则改编平面广告为实验材料,以广告类型（幽默,非幽默）、商品类别为自变量,以广告评价、广告顺序为协变量,以商品的印象程度、喜爱程度、购买意向为因变量,进行平衡设计实验。结果表明,幽默广告具有较好广告效果,可以提高受众对大宗工具、小奖赏和小工具型商品的记忆;幽默平面广告更适用于低风险、功能性商品,不适用于高风险、享乐性商品。     

THE UNIFORMITY OF NATURAL LAWS IN VICTORIAN BRITAIN: NATURALISM,THEISM, AND SCIENTIFIC PRACTICE

Abstract. A historical perspective allows for a different view on the compatibility of theistic views with a crucial foundation of modern scientific practice: the uniformity of nature, which states that the laws of nature are unbroken through time and space. Uniformity is generally understood to be part of a worldview called “scientific naturalism,” in which there is no room for divine forces or a spiritual realm. This association comes from the Victorian era, but a historical examination of scientists from that period shows that uniformity was an important part of both theistic and naturalistic worldviews. Victorian efforts to maintain the viability of miracles and divine action within a universe ruled by natural laws receives special attention. The methodological practices of theistic and naturalistic scientists in the nineteenth century were effectively indistinguishable despite each group's argument that uniformity was closely dependent on their worldview. This similarity is used to reexamine both the reasons for the decline of the role of religion within the scientific community and claims made by the intelligent design movement about the relationship of science and religion.
