人格特质与认知能力的关系及其年龄差异

人格是影响认知能力的重要因素, 不同的人格特质与认知能力的关系不同, 人格与认知能力的关系在不同年龄阶段也有所不同。当前的研究主要探讨了人格特质与认知能力之间的关系以及不同人格特质对不同认知能力的影响, 并在不同的年龄阶段进行比较。有关不同人格特质对认知能力的影响结果逐渐清晰, 但现有的研究结果存在很多争议。未来可以在人格的稳定性及其对认知能力的影响、人格对认知能力影响的作用机制及其相关影响因素、跨文化研究和研究范式等方面继续深化, 以获取对该研究问题更科学的研究结论。

Examining the Incremental Validity and Adverse Impact of Cognitive Ability and Conscientiousness on Job Performance

Using archival data from a large home improvement organization, the current study examined the incremental validity of conscientiousness over cognitive ability in predicting different performance criteria. Also, the study examined the effects of conscientiousness and cognitive ability on adverse impact. Results indicated that conscientiousness provided incremental validity over cognitive ability in the prediction of several performance criteria. Specifically, conscientiousness had the highest increases in validity over cognitive ability in the prediction of contextual performance factors (e.g., contextual performance, customer service orientation, dealing with others). However, the addition of conscientiousness failed to ameliorate the adverse impact associated with cognitive ability. In addition, limitations of the study and future directions of research are addressed.     

In pursuit of job satisfaction and happiness: Testing the interactive contribution of emotion‐regulation ability and workplace social support

The present study focuses on the interplay of emotion‐regulation ability and perceived workplace social support as predictors of job satisfaction and happiness in a Spanish multi‐occupational sample. A total of 494 working adults (39.4% females) took part in this study. Emotion‐regulation ability and perceived support from colleagues and supervisors were positively associated. In addition, emotion‐regulation ability and perceived support from colleagues and supervisors showed positive associations with job satisfaction and happiness. Furthermore, considering results from moderation analyses, when low levels of perceived workplace social support were reported, the relationship between emotion regulation and both job satisfaction and happiness was stronger than in cases of higher perceived workplace support. In line with previous studies, these findings suggest that training in emotion regulation abilities may take into consideration the potential moderating role of job characteristics such as support from colleagues and supervisors. Finally, theoretical and practical implications of the joint study of these factors in line with the Job Demands‐Resources model and the Emotional Intelligence framework are discussed.     

数学学习困难初中生的中央执行系统特点

为揭示数学学习困难学生的认知过程加工特点,筛选上海111名初中生（男生46名,女生68名,平均年龄11.97岁）比较数学困难学生（55名）与数学优秀学生（56名）的中央执行系统的表现差异,通过反应停止任务和Flanker任务考察抑制能力以及注意控制能力。结果发现各种抑制和注意控制条件下,数困组学生的正确率低于数优组;在具有干扰的情况的成绩更能有效预测数学成绩;中央执行系统能力在初中总体具有上升发展趋势,数困生的发展具有波动性。因此,数学学习困难在中央执行系统中的缺损主要是对抗干扰的能力不足,而非简单的加工速度。     

The long-term effects of ability grouping in mathematics: A national investigation

The complexities of school tracking have resulted in patchy explanations of how it might affect students’ academic success. We aim to develop a comprehensive understanding of tracking by investigating its long-term relationships with student outcomes. Our study is informed by sociological and social psychological theoretical perspectives that explain how this school practice may wield its influence. We use panel data from the National Education Longitudinal Survey (NELS:88) for a comprehensive analysis of the associations between ability grouping in the eighth grade and subsequent social psychological and academic variables in the 10th and 12th grades, respectively. By covering three waves of data that monitor the mathematics progress of middle school youngsters as they go through high school, we present the durable relationships of tracking. Our method compares students in tracked and untracked schools, and further partitions these students into high and low ability groups. Our results reaffirm that tracking has persistent instructional benefits for all students. Yet, high-achieving students who are tracked in middle school may suffer considerable losses in self-concept that subsequently depress their achievement, and mathematics course-taking. Implications are for a broad range theory of tracking and for further empirical work on the viability of heterogeneously-grouped classes.An earlier version of this paper was presented at the International Sociological Association (ISA) XV World Congress of Sociology, Brisbane, Australia, July 7th through 13th, 2002     

Manipulation of responsibility in non-clinical subjects: does expectation of failure exacerbate obsessive-compulsive behaviors?

An exaggerated sense of responsibility is currently considered as the ground for the obsessive-compulsive disorder. Obsessive-like behaviors, such as hesitations and checks, may be induced in non-clinical subjects by increasing perceived responsibility (i.e., perceived personal influence on negative outcomes). In line with Salkovskis' proposal [The cognitive approach to anxiety: threat beliefs, safety-seeking behavior, and the special case of health anxiety and obsessions, in: P.M. Salkovskis (Ed.), Frontiers of Cognitive Therapy, Guilford, New York], we tested the hypothesis that reduced coping abilities (i.e., an exaggerated expectation of failure) are another effectual factor contributing to obsessive-like behaviors. We examined 47 normal volunteers in a visuo-spatial memory task, and manipulated their perceived personal influence and expectation of failure by giving differential instructions and feedback about their performance. Increase of perceived personal influence induced slowness, hesitations and checks without enhancing performance. Expectation of failure exacerbated obsessive-like behaviors, again without affecting performance. These results confirm the role of responsibility in obsessive-like behavior and indicate that reduced coping abilities may contribute to worsen dysfunctional strategies.     

Working memory and literacy as predictors of performance on algebraic word problems

Previous studies on individual differences in mathematical abilities have shown that working memory contributes to early arithmetic performance. In this study, we extended the investigation to algebraic word problem solving. A total of 151 10-year-olds were administered algebraic word problems and measures of working memory, intelligence quotient (IQ), and reading ability. Regression results were consistent with findings from the arithmetic literature showing that a literacy composite measure provided greater contribution than did executive function capacity. However, a series of path analyses showed that the overall contribution of executive function was comparable to that of literacy; the effect of executive function was mediated by that of literacy. Both the phonological loop and the visual spatial sketchpad failed to contribute directly; they contributed only indirectly by way of literacy and performance IQ, respectively.     

Can wild common marmosets (Callithrix jacchus) solve the parallel strings task?

Patterned string tasks are a test of perceptual capacity and the understanding of means-end connections. Primates can solve complex forms of this task in laboratories. However, this may not indicate the level of such cognition that is commonly employed in the wild, where decision-making time is often short and distractions such as predator avoidance and competition between conspecifics are often prevalent. The current study tests whether wild common marmosets (Callithrix jacchus) can successfully complete the simplest form of the patterned string task, parallel strings, while in their natural environment. Although 12 out of 13 marmosets could successfully complete the task, in previous laboratory-based studies on primates, the errors at this task by all primate species tested were consistently lower than in the present study. This is probably explained by the added difficulties imposed by the natural setting of the task in the present study, exemplified by a significant increase in observed vigilance behaviour by subject animals prior to attempts at the task that were unsuccessful. The undertaking of such tasks by common marmosets in situ probably provides a more reasonable representation of the levels of cognitive capacity expressed by this species in the wild than do laboratory-based studies of the task.
