气质稳定性与发展性新进展*

气质的稳定性和发展性是心理学研究争论已久的问题。遗传×环境的研究视角再次打破了传统研究模式,取而代之的是气质稳定性与发展性的共存,遵循传统先天论——环境论——先天论——先天论×环境论的总体发展态势。该视角在拓展气质研究领域的同时,也成为未来研究的主要取向。本文首先综述了由于研究手段的更新和多元化而引发的气质稳定性和发展性两方面的最新实证研究,探讨了稳定性中遗传基因加性效应和非加性效应、脑生理基础以及个体气质发展性的内部、外部影响因素。然后,从研究样本的年龄段、气质的生理机制和儿童气质的纵向研究、亲子互动及师生互动方面的研究等方面提出目前我国气质研究未来方向。     

Effect of Heel Heights on Female Postural Control During Standing on a Dynamic Support Surface With Sinusoidal Oscillations

The authors aimed to investigate female balance or stability control with comparative analysis of the center of pressure trajectory and plantar pressure distribution with different high-heeled shoes while standing on a dynamic surface with multidirectional perturbations. College females with at least 2 years' history of wearing high-heel shoes voluntarily participated in the test with a Novel Pedar insole (Novel, GmBH, Munich, Germany. With heels height increasing, the pressure time integral obviously transfer to the medial forefoot region, with center of pressure trajectory medially deviated significantly, either under anteroposterior or mediolateral perturbations. The passive plantarflexion position of ankle incurred by high heel increased the range of motion in the frontal plane but decreased ankle stability, thus increasing the challenge of body balance maintenance.     

The Metaphors of Knowledge and Academic Impact

This essay discusses critically the ways in which different metaphors employed to illustrate the practices of knowledge production and knowledge acquisition as well as scientific and scholarly research shape our understanding of the academic form of life. The essay examines the metaphors of knowledge and their role in academia by means of philosophical analysis and a rhetorical analysis of language, thereby defending the core values of academic freedom. It focuses on two pairs of metaphors highly relevant to the tensions characteristic of contemporary academic work: verticality and horizontality, on the one hand, and change and stability, on the other. The entanglement of perspectives from philosophy and historical rhetoric serves a metaphilosophical goal here: to show that our philosophical understanding of the nature of inquiry will be considerably enhanced if we seriously, and with both historical and literary sensibilities, study the metaphors we use in characterizing our epistemic and cognitive projects.     

Ethnicity, education, and the temporal stability of personality traits in the East Baltimore Epidemiologic Catchment Area study

We examined the influence of age, gender, Black vs. White ethnicity, and education on five indices of personality stability and change across an average interval of 8 years in the East Baltimore Epidemiologic Catchment Area study. In the full sample (n = 505, aged 30–88), examination of structural, rank-order, ipsative, and mean level stability, as well as indices of reliable change suggested that NEO-PI-R personality traits showed moderate to high levels of stability over time. There were few age and gender effects on temporal stability but rank-order, ipsative, and mean level stability were lower among Blacks and individuals with lower education. Future research should explore additional demographic predictors of temporal plasticity in a diverse range of samples, and employ observer ratings to assess personality.     

Bounded stability of the quiet standing posture: an intermittent control model

The paper presents a control model of body sway in quiet standing, which aims at achieving bounded stability by means of an intermittent control mechanism. Control bursts are generated when the current state vector exits an area of uncertainty around the reference point in the phase plane. This area is determined by the limited resolution of proprioceptive signals and the burst generation mechanism is predictive in the sense that it incorporates a rough, but working knowledge (internal model) of the biomechanics of the human inverted pendulum. We show that such a model, in spite of its simplicity and of the fact that it relies on very noisy measurements, is robust and can explain in a detailed way the measured sway patterns.     

Disruptive decisions to leave home: Gender and family differences in expatriation choices

I developed a theoretical model predicting how gender and family status would influence employee willingness to expatriate, international job search behavior, and expatriation decisions and tested the model in a longitudinal investigation. Australian employees comprising 230 females and 401 males with partners and/or children and 208 female and male childless singles were surveyed three times over three years. Employees who had greater personal agency and less family barriers were more willing to expatriate, to search for international jobs, and to eventually leave their home countries. Having a family restricted females’ ability to transform their willingness to expatriate into an international job search to a greater extent than it did males’. In turn, international job search predicted actual expatriation for a job. Overall, the expatriation interests of women with partners and/or children were least realized (most inhibited) in international job search and subsequent expatriation behavior. The interests of childless single employees were most realized. The study challenges current thinking on women’s willingness to expatriate by demonstrating that women are willing to expatriate, but family factors lead to women being less able to transform their willingness into an international job search than men, subsequently flowing on to women expatriating less for work than men.     

2～11岁儿童问题行为的稳定性与变化

本研究采用追踪研究方法,考察了儿童2岁、4岁、7岁、11岁时内隐问题行为和外显问题行为的稳定性和变化。结果发现,各个年龄阶段,父母报告的问题行为都具有中等程度的相关。儿童的问题行为2岁时最多,此后开始下降,11岁时问题行为最少。儿童的问题行为具有中等程度的连续性,2岁、4岁、7岁、11岁的问题行为之间的相关均非常显著。     

Long-term stability in the Big Five personality traits in adulthood

This study investigated the stability of the Big Five personality traits in adulthood from age 33 to 42. Participants (89 men, 103 women) were drawn from the ongoing Jyväskylä Longitudinal Study of Personality and Social Development. The results showed that the mean‐level of Neuroticism decreased whereas the mean‐level of Extraversion, Openness to Experience, Agreeableness, and Conscientiousness increased from age 33 to 42. The Structural Equation Modeling analyses revealed both gender differences and similarities in the rank‐order stability of the Big Five: Neuroticism and Extraversion were more stable in men than in women, whereas Openness to Experience, Agreeableness, and Conscientiousness were as stable in men as in women. Stability coefficients for the Big Five personality traits across 9 years were moderate to high, ranging from 0.73 to 0.97 in men and from 0.65 to 0.95 in women. The highest gender‐equal stability was found for Openness to Experience and the lowest for Conscientiousness.     

Adolescent psychopathy features: 6-year temporal stability and the prediction of externalizing symptoms during the transition to adulthood

This study investigated the 6-year stability and predictive validity of adolescent psychopathy features during the transition to young adulthood. It represents one of the longest outcome studies of youth psychopathy to date, and therefore addresses a primary criticism of the research area (i.e., lack of demonstrated associations between child and adult psychopathy features). Recruited participants were 475 males enrolled in the Minnesota Twin and Family Study who had completed a research-based measure of psychopathy features consisting of separate emotional detachment (or affective) and antisocial tendencies (or behavioral) subscales. These psychopathy features and various externalizing symptoms (i.e., conduct problems, impulsivity, and substance use disorder) were assessed through rating scales and structured diagnostic interview at an intake assessment (ages 16-18) and 6-year follow-up. Consistent with prediction, adolescent psychopathy features displayed moderate stability across the transition from adolescence to adulthood [intraclass correlation coefficients (ICCs) = 0.40-0.41]. The antisocial tendencies subscale was uniquely related to most externalizing symptoms both in adolescence and in adulthood, whereas the emotional detachment subscale showed appropriate discriminant validity in its lack of association with externalizing symptoms. These findings suggest that psychopathy features are relatively stable from adolescence to adulthood and provide possible insights into the development and maintenance of externalizing difficulties during the adult transition.     

Organizational embeddedness and occupational embeddedness across career stages

This article proposes a theoretical framework to study organizational embeddedness and occupational embeddedness. Organizational embeddedness is the totality of forces (fit, links, and sacrifices) that keep people in their current organizations, while occupational embeddedness is the totality of forces (fit, links, and sacrifices) that keep people in their current occupations. The proposed framework identifies the antecedents of these parallel processes and when and why they can diverge. It also highlights the role that individuals’ career stages play in the embedding process. The article concludes with a discussion of avenues for future research on job turnover and occupation change and implications for management practice.
