When Problems Lead to Ideas: The Roles of Daily Vigor and Social Interactions

In this study, we investigate idea generation by conducting a diary study. We hypothesized that idea generation depends on problem identification, and that this relation is moderated by two factors: (a) the number of social interactions an individual has with “non‐redundant” network connections, and (b) an individual's level of vigor. The hypotheses were tested by making use of a diary study among 31 employees of a Dutch applied university over a period of 2 weeks. Results showed that idea generation results from the identification of problems that require new ideas to solve them. An individual's number of social interactions and the level of redundancy of these social interactions moderated this relation. The level of vigor of an individual did not predict idea generation, but results suggest that vigor is needed for interacting with others. Furthermore, this study contributes to the creativity research using a new approach to look at the effects of social interactions by relating them to the overall structure of social networks.     

Predicting incident falls: Relationship between postural sway and limits of stability in older adults

BackgroundWe have previously shown that objective measurements of postural sway predicts fall risk, although it is currently unknown how limits of stability (LOS) might influence these results.Research question: How integrated postural sway and LOS measurements predict the risk of incident falls in a population-based sample of older adults.Methods:The sample for this prospective observational study was drawn from the Healthy Ageing Initiative cohort and included data collected between June 2012 and December 2016 for 2396 men and women, all 70 years of age. LOS was compared to postural sway with measurements during eyes-open (EO) and eyes-closed (EC) trials, using the previously validated Wii Force Plate. Fall history was assessed during baseline examination and incident falls were collected during follow-up at 6 and 12 months. Independent predictors of incident falls and additional covariates were investigated using multiple logistic regression models.Results:During follow-up, 337 out of 2396 participants (14%) had experienced a fall. Unadjusted regression models from the EO trial revealed increased fall risk by 6% (OR 1.06, 95% CI 1.02–1.11) per each centimeter squared increase in sway area and by 16% (OR 1.16, 95% CI 1.07–1.25) per 1-unit increase in Sway-Area-to-LOS ratio. Odds ratios were generally lower when analyzing EC trials and only slightly attenuated in fully adjusted models.Significance:Integrating postural sway and LOS parameters provides valid fall risk prediction and a holistic analysis of postural stability. Future work should establish normative values and evaluate clinical utility of these measures.     

小学儿童词汇知识与阅读理解的关系：交叉滞后研究

对小学1、3、5年级共399名学生进行为期1年的追踪测查, 使用交叉滞后模型检验小学低、中、高年级儿童词汇知识与阅读理解的关系。在控制了语音意识、语素意识、一般认知能力和自回归效应之后, 结果发现：在小学低年级, 词汇知识与阅读理解之间未发现显著的纵向预测关系; 在中年级, 词汇知识和阅读理解存在显著的双向预测关系; 在高年级, T1的阅读理解能够显著预测T2的词汇知识, 而T1的词汇知识对T2阅读理解的预测作用不显著。研究结果表明词汇知识与阅读理解的关系在小学不同年级段存在不同的模式, 这一发现支持了阅读发展阶段论, 并对阅读三角理论进行了一定的补充。     

Unravelling the Interplay Between Genetic and Environmental Contributions in the Unfolding of Personality Differences from Early Adolescence to Young Adulthood

In two studies, we examined the genetic and environmental sources of the unfolding of personality trait differences from childhood to emerging adulthood. Using self‐reports from over 3000 representative German twin pairs of three birth cohorts, we could replicate previous findings on the primary role of genetic sources accounting for the unfolding of inter‐individual differences in personality traits and stabilizing trait differences during adolescence. More specifically, the genetic variance increased between early (ages 10–12 years) and late (ages 16–18 years) adolescence and stabilized between late adolescence and young adulthood (ages 21–25 years). This trend could be confirmed in a second three‐wave longitudinal study of adolescents' personality self‐reports and parent ratings from about 1400 Norwegian twin families (average ages between 15 and 20 years). Moreover, the longitudinal study provided evidence for increasing genetic differences being primarily due to accumulation of novel genetic influences instead of an amplification of initial genetic variation. This is in line with cumulative interaction effects between twins' correlated genetic makeups and environmental circumstances shared by adolescent twins reared together. In other words, nature × nurture interactions rather than transactions can account for increases in genetic variance and thus personality variance during adolescence. © 2019 European Association of Personality Psychology     

青少年公正世界信念的发展轨迹及其影响因素:一项多水平分析

A Novel,Integrated Cognitive-Behavioral Therapy for Co-Occurring Posttraumatic Stress and Substance Use Disorders: A Case Study

Posttraumatic stress disorder (PTSD) and substance use disorders (SUD) are complex psychiatric conditions that commonly co-occur. No preferred, evidence-based treatments for PTSD/SUD comorbidity are presently available. Promising integrated treatments have combined prolonged exposure therapy with cognitive-behavioral relapse prevention therapy for SUD. We describe a case study that showcases a novel, integrated cognitive-behavioral treatment approach for PTSD/SUD, entitled Treatment of Integrated Posttraumatic Stress and Substance Use (TIPSS). The TIPSS program integrates cognitive processing therapy with cognitive-behavioral therapy for SUD for the treatment of co-occurring PTSD/SUD. The present case report, based upon a woman with PTSD comorbid with both cocaine and alcohol dependence, demonstrates that TIPSS has the potential to effectively reduce PTSD symptoms as well as substance use.     

Can faith move mountains? How implicit theories about willpower moderate the adverse effect of daily emotional dissonance on ego-depletion at work and its spillover to the home-domain

Recent findings have demonstrated that implicit theories about willpower (the belief whether willpower relies on a limited vs. nonlimited resource) moderate the ego-depletion-effect. This study examines this moderating mechanism in occupational settings where employees increasingly have to deal with the unpleasant state of emotional dissonance, which requires the exertion of volitional self-control. By integrating findings on implicit theories about willpower, arguments brought up by the strength model of self-control, and notions from the spillover literature, we propose that believing in a nonlimited resource theory of willpower buffers the effect of emotional dissonance on ego-depletion at work and diminishes the spillover of ego-depletion from the work- to the home-domain. In a diary study covering 10 working days (N = 71), we examine a moderated mediation model in which ego-depletion at work mediates the relation between emotional dissonance and ego-depletion at home and analyse whether implicit theories about willpower moderate both paths (a and b) of the proposed mediation model. Our results provide support for the mediation hypothesis and show that endorsing a nonlimited resource theory buffers the effect of emotional dissonance on ego-depletion at work, thereby disrupting the indirect effect of emotional dissonance on ego-depletion at home. Subsequently, we discuss implications of holding a nonlimited resource theory.     

How long does it last? Prior victimization from workplace bullying moderates the relationship between daily exposure to negative acts and subsequent depressed mood

The aim of the present study was to examine the relationships between daily exposure to negative acts and depressed mood on the same day and on the days following the exposure, and to test the hypothesis that these relationships would be stronger among those who have recently gone through a process of victimization from workplace bullying. The sample comprised 110 naval cadets participating in two different eleven-week tall ship voyages from Northern Europe to North America. Victimization from workplace bullying the last six months was measured one day prior to the voyages. Exposure to negative acts and depressed mood was measured daily during the first 33 consecutive days of the voyages. The results of multilevel modelling indicated that exposure to negative acts was related to higher levels of depressed mood on the same day as the exposure among all cadets, regardless of victimization status. However, exposure to negative acts predicted higher levels of depressed mood one and two days following the exposure among victims only. The theoretical and practical implications of these findings are discussed.     

Factors that enhance academic learning and study behaviours: A qualitative study

This exploratory study examined students’ conceptions of factors that enhance the use and application of academic learning and study strategies (LSS). A qualitative approach was used to explore the conceptions of 23 first-year university students (female = 14; age range = 18–24 years). Data were collected using unstructured interviews and narrative sketches. Thematic analysis revealed three themes; namely clarity, emotional intelligence, and life circumstances. LSS clarity showed that knowledge of the self as a learner and well-defined educational goals can enhance engagement in the academic study process. Emotional intelligence as LSS referred to the importance of self-management and emotional regulation; while life circumstances in LSS emphasised the impact of real world challenges that affect the learning process. Student development counselling for LSS should consider the extent to which students have a sense of clarity, emotional intelligence, and life orientation important for their education success.
