The relations between cognitive ability and personality: Convergent results across measures

Several studies have investigated the relations between cognitive ability and Big Five personality constructs. The present study extended previous research by (a) examining these relationships in large samples (total N = 120,014), (b) including several measures of cognitive ability and personality, (c) examining both domain and facet-level personality scores, (d) expanding the personality domains studied to include Machiavellianism, and (e) correcting the observed correlations for range restriction and reliability to provide a better statistical estimate of the relations between the cognitive and personality scores and constructs. Results were consistent with prior research showing a positive relationship between cognitive ability and Openness and negative relationships between cognitive ability and Neuroticism and Conscientiousness. Negative relations between cognitive ability and Extraversion and Agreeableness also were observed. Machiavellianism, not part of the Big Five was found to have a positive correlation with cognitive ability. Of particular interest was the finding that the relations between cognitive ability and personality were affected by the specific content of the cognitive and personality measures. Cognitive measures with verbal content were more strongly correlated with personality than were cognitive measures with math or nonverbal content for all of the samples. Also, there was considerable variability in the cognitive-personality correlations for the facets underlying each personality domain. The variability in correlations at the facet-level implies that cognitive-personality relationships at the domain-level will vary as a function of the specific content of the cognitive and personality measures. Overall, the results provide support for cognitive-personality association at the measurement level.     

家庭支持与朋友支持对不同自理能力老年人抑郁水平的影响

探讨社会支持中的家庭支持和朋友支持对不同自理能力老年人抑郁水平的影响作用。结果发现:(1)社会支持可有效缓解老年人抑郁症状;(2)对个体而言,家庭支持是较稳定的支持来源,受个体年龄和健康水平的影响较小,而朋友支持变动较大,随年龄增长和健康水平的下降,朋友支持逐渐减少;(3)社会支持对不可完全自理老年人抑郁水平的解释率高于对可完全自理老年人抑郁水平的解释率;(4)对于生活可完全自理的老人,朋友支持比家庭支持有更大的预测作用,而对于生活不能完全自理的老人,家庭支持的作用更大。     

Who’s afraid of the big bad wolf? The interweaving of values and science

The role of values in the scientific process is widely debated. But evidence and values cannot be neatly separated. Instead, values infuse the entire scientific process, starting with the choice of research questions. Research avenues are selected based on prior beliefs about the workings of the world. In fact, informally assigned prior probabilities and normalizing constants play an essential role in distinguishing causes from correlations and ignoring irrelevant associations that would otherwise be suggested by raw data. But since these initial probabilities often have a heterogeneous pedigree – often not all that went into their formation is known or knowable – it becomes difficult to cleanly separate evidence from values. At the same time, this reality does not undermine science’s unique status in generating knowledge. This is because it is not the evidence per se generated by science, but rather the method by which science generates it, that justifies science’s privileged role.     

Evidence: wanted,alive or dead

This paper is meant to link the philosophical debate concerning the underdetermination of theories by evidence with a rather significant socio-political issue that has been taking place in Canada over the past few years: the so-called ‘death of evidence’ controversy. It places this debate within a broader philosophical framework by discussing the connection between evidence and theory; by bringing out the role of epistemic values in the so-called scientific method; and by examining the role of social values in science. While it should be admitted that social values play an important role in science, the key question for anyone who advocates this view is: what and whose values? The way it is answered makes an important epistemic difference to how the relation between evidence and theory is appraised. I first review various arguments for the claim that evidence underdetermines theory and shows their presuppositions and limitations, using conceptual analysis and historical examples. After broaching the relation between evidence and method in science by highlighting the need to incorporate epistemic values into the scientific method, my discussion focuses on recent arguments for the role of social values in science. Finally, I address the implications of the approach outlined for the current ‘death of evidence’ debate in Canada.     

2～3.5岁儿童执行功能发展特点及其言语能力的影响

2~3.5岁是婴儿成长到幼儿的重要发展转折期,也是儿童执行功能及言语能力的发展萌芽期。研究通过测查北京市81名2~3.5岁儿童在固定盒子任务、搭积木任务、A非B任务和皮博迪图片词汇测验上的表现,探究了该年龄段儿童执行功能的发展特点、各成分间的内部关系、以及言语能力对执行功能的影响。结果发现:(1)在2~3.5岁期间,除认知灵活性外,儿童的工作记忆与抑制控制均快速发展,其中,2.5岁前后是工作记忆与抑制控制的重要发展时期;(2)在2~3岁期间,认知灵活性与工作记忆之间相关密切,在3~3.5岁期间,认知灵活性与抑制控制的相关密切,3岁是儿童执行功能内部成分关系的重要发展转折期;(3)在2~3.5岁期间,儿童言语能力呈现快速发展,并且言语能力对该年龄段执行功能各成分间关系产生一定的影响,但不同言语能力的儿童在执行功能各成分的表现并没有显著差异。     

Challenges in Developing a Cultural Evidence‐Based Psychotherapy in the USA: Suggestions for International Studies

In this article, we underscore some of the cultural challenges and limitations of the evidence‐based psychotherapy (EBP) utilised within the USA with the hope that these problems will be avoided or ameliorated in Australia and other countries. Although the EBP research is very diverse and complex, we categorise this fast‐growing literature using a threefold classification system that underscores culture. This classification system is proposed to examine the influence of culture on EBPs. The three categories used are (a) universal evidence‐based psychotherapies or universal psychotherapies, (b) race and ethnic minority evidence‐based psychotherapies or racial/ethnic psychotherapies, and (c) cultural evidence‐based psychotherapies or cultural psychotherapies. After each category is described, its benefits and limitations are discussed, emphasising implications for culturally diverse and international studies. We conclude with suggestions to promote the advancement of a more effective and inclusive cultural EBP in which researchers from different countries can collaborate and learn from each other.     

大学生对心理健康必备能力的认知

本研究以200名大学生为被试,以访谈及问卷的方式对大学生心理健康必备能力的认知进行了调查研究,并建立了大学生心理健康必备能力认知结构模型,结果表明:大学生所认知的自己心理健康必备能力由自我调控、社会应对、学习和人际交往这四个方面的能力组成,它们彼此独立,但又相互关联。     

幼儿元认知"乐观主义现象"研究述评

儿童元认知发展是当代发展心理学研究的热点领域之一,其中儿童对自身能力的认识与评估又是研究者很感兴趣的课题。大量研究表明,与年长儿童和成人相比,年幼儿童特别是学龄前儿童往往对自己的能力和在各种任务中的成绩作出不切实际的高估,这种高估具有跨领域的一致性,并且具有内在固执性,即通常不受过去失败经验的影响。这就是所谓幼儿元认知“乐观主义现象”。本文对这一领域的相关研究进行整体回顾与分析,并在此基础上尝试对这一现象产生的原因及影响因素作出解释和说明。     

The fallibility of memory in judicial processes: Lessons from the past and their modern consequences

The capability of adult and child witnesses to accurately recollect events from the past and provide reliable testimony has been hotly debated for more than 100 years. Prominent legal cases of the 1980s and 1990s sparked lengthy debates and important research questions surrounding the fallibility and general reliability of memory. But what lessons have we learned, some 35 years later, about the role of memory in the judicial system? In this review, we focus on what we now know about the consequences of the fallibility of memory for legal proceedings. We present a brief historical overview of false memories that focuses on three critical forensic areas that changed memory research: children as eyewitnesses, historic sexual abuse and eyewitness (mis)identification. We revisit some of the prominent trials of the 1980s and 1990s to not only consider the role false memories have played in judicial decisions, but also to see how this has helped us understand memory today. Finally, we consider the way in which the research on memory (true and false) has been successfully integrated into some courtroom procedures.
