Personality and reasoning ability during retirement age: Report from a Swedish population-based longitudinal study

We examined the association between personality and level and change in reasoning ability in a population-based sample of older adults (62–68 years) using a three-year annual follow-up longitudinal study design (HEARTS; N = 3851). Personality traits were measured using the Mini-IPIP scale and reasoning using a short form of Raven’s Matrices. Findings from a structural equation model, controlling for age, education, and sex, revealed that higher levels on extraversion, conscientiousness, and neuroticism were associated with lower reasoning ability (βs: −0.17 to −0.09). Higher levels of openness were associated with better reasoning (β: 0.16). We found no association with rate of change. This evidence replicates previous findings demonstrating that personality traits are associated with individual differences in cognition among older adults.     

Executive functions in elite athletes – Comparing open-skill and closed-skill sports and considering the role of athletes' past involvement in both sport categories

Previous research documented differences in executive functions between elite athletes in different sports. It was argued that athletes in sport disciplines with higher cognitive demands (i.e., open-skill) show better executive functions than athletes in less cognitively challenging sport disciplines (i.e., closed-skill). In the current study, we aimed at detecting differences in executive functions between elite athletes in open-skill versus closed-skill sports and questioned the role of their total involvement in these sports until the age of 18 on executive functions.Seventy-five elite athletes (45 males and 30 females; M_age = 23.03 ± 4.41 years) from various sports were classified as open- or closed-skill athletes based on the sport they currently competed in. The athletes conducted a series of neuro-psychological tests measuring working memory, inhibition, and cognitive flexibility (Design Fluency test, Trail Making test, Flanker task, and a 2-back task). Retrospective interviews assessed athletes' sport involvement in open-skill and closed-skill sports until the age of 18.MANCOVAs revealed that athletes in open-skill sports performed better on measures of working memory and cognitive flexibility. Generalized Linear Models displayed that elite athletes in closed-skill sports, with greater involvement in open-skill sports until the age of 18, performed better during working memory and cognitive flexibility tasks.The results indicate that extensive time spent in open- and closed-skill sports can affect executive functions in elite athletes. A high involvement in open-skill sports proved to be beneficial for executive functions, in particular for elite athletes in closed-skill sports. These findings suggest that experiences in cognitively demanding sports may cause benefits for the development of executive functions.     

认知负载对基于动机的情绪刺激加工的影响

结合数数任务和情绪flanker任务,探究不同认知负载条件下,高低趋近动机对情绪刺激加工的影响。结果发现：高负载组中,高趋近动机条件下,对积极目标刺激的反应显著快于消极目标刺激;低趋近动机条件下,对消极目标刺激的反应显著快于积极目标刺激。且高负载组中,各条件下的反应大多都显著慢于低负载组。低负载组中没有发现各条件之间的差异。结果表明,高负载条件下,高趋近动机促进了积极情绪刺激的加工,低趋近动机促进了消极情绪刺激的加工,高负载在一定程度上阻碍了情绪刺激的加工。     

中国情境下家长式领导与员工绩效关系的元分析

本研究采用元分析技术和效标剖面元分析技术探讨中国情境下家长式领导与员工绩效之间的关系。通过文献收集与筛选, 共纳入139项研究400个效应值(N = 44605)。元分析结果发现：(1)仁慈领导、德行领导与任务绩效和组织公民绩效有较强的正相关关系, 与反生产绩效有较强的负相关关系。与之相反, 威权领导与任务绩效和组织公民绩效之间有显著的负相关关系, 与反生产绩效显著正相关。(2)低威权领导剖面(仁慈领导和德行领导水平高)对任务绩效和组织公民绩效的预测力最强, 高威权领导剖面(仁慈领导和德行领导水平低)对反生产绩效的预测力最强。(3)年龄能够调节家长式领导部分维度和绩效之间的关系强度, 性别对家长式领导分维度和绩效关系的调节效应不显著。研究结果进一步揭示了中国情境下家长式领导与个体绩效之间关系的“真相”。     

Theories,structures and simulations in the research of early mentalizing

The objective of this paper is to propose some new approaches that could be used in the research of the development of mindreading in infancy. I argue that the mentalizing system should be approached as a developing hierarchical structure that acquires the ability to orient attention to the most significant features in the environment. The development of this system could be described by a series of implicit theories that share a common structure which provides continuity over theory change. According to this view, the early stages which have a fundamental role for the development of mindreading would be described by low-level theories, but as infants become increasingly efficient in predicting behavior of observed agents the higher-order entities become prioritized due to their relevance. Infants thus gradually develop the ability to predict the behavior of others in situations involving attribution of mental states. I propose a strategy based on the analysis of attention deployment that could help to decide which of the alternative theories provides the most adequate account of the mentalizing system at a certain developmental stage. I also suggest that computational modeling could contribute to the research in this area. Simulations of looking behavior based on different ontologies could prove to be useful for choosing the most adequate theory as well as for advancing the understanding of mechanisms involved in the development of theory of mind.     

Media Multitasking Effects on Cognitive vs. Attitudinal Outcomes: A Meta‐Analysis

Despite the recent proliferation of research on media multitasking, a comprehensive meta‐analytic review of its effects has not been available. Based on a review of 49 media multitasking studies, this meta‐analysis showed that multitasking has negative effects on cognitive outcomes, whereas it has positive effects on attitudinal (or persuasion‐related) outcomes. Moderator analyses suggested that the negative effects of multitasking on cognitive outcomes varied by (a) user control, (b) task relevance, and (c) task contiguity. Specifically, multitasking had greater effects (a) when media users had less control over the media, (b) for tasks that were unrelated, and (c) for tasks that were physically distant. Implications for future multitasking research are further discussed.     

Fake feedback on pain tolerance impacts proactive versus reactive control strategies

It is well-known that beliefs about one’s own ability to execute a task influence task performance. Here, we tested the hypothesis that beliefs about a specific self-control capacity, namely pain tolerance, modulate basic cognitive control processes. Participants received fake comparative social feedback that their ability to tolerate painful stimulations was either very poor or outstanding after which they performed an unrelated go/no-go task. Participants receiving low-tolerance feedback, relative to high-tolerance feedback, were less successful at inhibiting their responses and more influenced by previous trial conditions, as indicated by an increased slowdown following errors and more failed inhibitions following go-trials. These observations demonstrate a shift from a more proactive to a more reactive control mode. This study shows that providing feedback about one’s own capacity to control impulsive reactions to painful stimulations directly influences low-level cognitive control dynamics.     

Personality profiles and health: Longitudinal evidence among Finnish adults

Kinnunen, M.‐L., Metsäpelto, R. L., Feldt, T., Kokko, K., Tolvanen, A., Kinnunen, U., Leppänen, E. & Pulkkinen, L. (2012). Personality profiles and health: Longitudinal evidence among Finnish adults. Scandinavian Journal of Psychology 53, 512–522. This study investigates the associations of longitudinal Big Five personality profiles with long‐term health in 304 adults (53% males). Personality traits (Neuroticism, Extraversion, Openness, Conscientiousness, Agreeableness) were assessed at ages 33, 42, and 50. Subjective (self‐rated health, symptoms, psychological distress) and objective (body mass index, waist‐to‐hip ratio, blood pressure, cholesterol, triglycerides) indicators of health were measured at ages 42 and 50. Five longitudinally stable personality profiles were extracted over 17 years by latent profile analysis. The levels of traits were the same in each profile at each age. Resilient individuals (N = 65; Neuroticism low, other traits high) had the best subjective health and Overcontrolled individuals (N = 40; Neuroticism high, other traits low) the poorest health over eight years. Reserved individuals (N = 25; high Conscientiousness, other traits low), Undercontrolled (N = 41; high Openness and Extraversion, low Conscientiousness), and Ordinary (N = 133; all traits scored medium) individuals were in the middle of these extremes in subjective health. No differences between the profiles were found in the objective indicators of health. Thus, overcontrol and resilience were most discriminative in terms of good health. Moreover, personality profiles revealed associations with health to be more nuanced than simply being composed of single traits. High Extraversion needed to be combined with high Conscientiousness (Resilients) in order to be associated with the best health; high Extraversion with low Conscientiousness (Undercontrolled) was associated with average health; and low Extraversion with high Neuroticism (Overcontrolled) was associated with the poorest health.
