Sensitivity to amplitude envelope rise time in infancy and vocabulary development at 3 years: A significant relationship

Here we report, for the first time, a relationship between sensitivity to amplitude envelope rise time in infants and their later vocabulary development. Recent research in auditory neuroscience has revealed that amplitude envelope rise time plays a mechanistic role in speech encoding. Accordingly, individual differences in infant discrimination of amplitude envelope rise times could be expected to relate to individual differences in language acquisition. A group of 50 infants taking part in a longitudinal study contributed rise time discrimination thresholds when aged 7 and 10 months, and their vocabulary development was measured at 3 years. Experimental measures of phonological sensitivity were also administered at 3 years. Linear mixed effect models taking rise time sensitivity as the dependent variable, and controlling for non‐verbal IQ, showed significant predictive effects for vocabulary at 3 years, but not for the phonological sensitivity measures. The significant longitudinal relationship between amplitude envelope rise time discrimination and vocabulary development suggests that early rise time discrimination abilities have an impact on speech processing by infants.     

Risk or resource: Does school climate moderate the influence of community violence on children’s social‐emotional development in the Democratic Republic of Congo?

Exposure to community violence is thought to create risk for the social and emotional development of children, including those children living in low‐income, conflict‐affected countries. In the absence of other types of community resources, schools may be one of the few community resources that can help buffer children from the negative effects of community violence exposure. We sampled 8,300 students ranging in age from 6–18 years in 123 schools from the eastern Democratic Republic of Congo to examine whether and how two distinct dimensions of positive school climate can protect two key features of children's social‐emotional development in the presence of community violence. Multi‐level models tested the hypothesis that students’ perceptions of a positive school climate moderated the relation between community violence and self‐reported mental health problems and peer victimization. Findings support the hypothesis. Specifically, a positive school climate protected against mental health problems and peer victimization in the presence of high community violence. Students who experienced high community violence and a negative school climate generally demonstrated the worst development. We find complex interactions between the dimensions of school climate and exposure to violence on student social‐emotional development that highlight the salience of children's contexts for developmental studies in low‐income countries. We use dynamic developmental systems theory and differential impact to discuss the dual potential of schools as a buffer against the effects of violence or as a source of compounded risk.     

Influence du leadership éthique sur l’engagement affectif et l’épanouissement psychologique : le rôle médiateur de la satisfaction vis-à-vis de l’équilibre entre domaines de vie

The inter-professional national agreement of 19 June 2013 emphasizes the role of managers in promoting quality of work life. The latter aims jointly at employees’ health and company performance due to commitment. In the present study we tested the indirect effect of ethical leadership on affective commitment and psychological flourishing via satisfaction with work–family balance. Among employees, 221 filled out a questionnaire. The results indicate, on the one hand, the positive links between ethical leadership and affective commitment and psychological flourishing, and on the other hand the mediating role of satisfaction with work–family balance in these two relationships. We provide recommendations to improve quality of work life.     

家庭社会经济地位与青少年自我效能感的关系：家庭支持的中介作用与性别因素的调节作用

为探讨家庭社会经济地位对青少年自我效能感的影响及其作用机制,该研究采用问卷法对520名青少年进行调查。结果表明：(1)家庭社会经济地位、家庭支持、自我效能感两两均显著正相关;女生的家庭支持显著高于男生,自我效能感显著低于男生;(2)家庭支持在家庭社会经济地位对自我效能感的影响中起中介作用;(3)该中介作用受到性别因素的调节,较之男生,女生的家庭支持受到家庭社会经济地位的影响作用更为显著。     

Characteristics of Family Interaction of Individuals with Hikikomori (Prolonged Social Withdrawal) From the Viewpoint of Behavior Theory

The cognitive behavioral approach for families of individuals with hikikomori (IWH) places importance on assessing family interaction from a behavior theory. However, there is no gold standard method for the assessment of family interaction of IWH. Additionally, the characteristics of the family interactions of IWH have not been clarified. This study aims to (a) develop the Family Interaction Scale for Hikikomori (FIS‐H) using parent‐reported data, and (b) clarify the characteristics of hikikomori cases. First, the FIS‐H factor structure was examined. Second, to examine the reliability and validity of the FIS‐H and the characteristics of hikikomori cases, parents of IWH (hikikomori‐group) and unaffected parents (without‐group) completed the FIS‐H and the Relationship Happiness Scale. Based on data from 146 parents, the FIS‐H preliminary version consisted of four factors with a total of 12 items (Study 1). The reliability and validity of the FIS‐H were also confirmed to be acceptable using data from 246 hikikomori‐group participants. The hikikomori‐group had higher FIS‐H scores than did the without‐group (Study 2). These results show that it is important to appropriately assess family interactions.     

Value Predicate Analysis: A Language‐Based Tool for Diagnosing Behavioral Tendencies of Religious or Value‐Based Groups in Regions of Conflict

This article introduces a language‐based tool for addressing the role of religion in violent conflicts. Value predicate analysis (VPA) is an easily transportable, relatively uncomplicated early warning tool for measuring the probable near‐future behavior of modest‐sized religious groups in settings of potential conflict. We show that it is possible to identify a range of nine types of probable group behavior toward other groups. This approach significantly refines current binary assessments of violent/not‐violent group conduct. The authors (1) provide a warrant for diagnosing religion‐group behavior through performative analysis; (2) present a theoretical overview of VPA; (3) summarize their research, data analysis, and field collection methods; (4) present field test results; and (5) conclude with recommendations for further research.     

Religion in Domestic Violence Prevention PSAs: The Role of Religiosity in Motivating Christian Bystanders to Intervene

Domestic violence is an ongoing health issue around the world, propelling individuals and organizations to seek out new and innovative ways to mitigate its widespread reach. Focusing on the potential of religion to positively impact messaging, the current study examines how Christian symbolism might be used to encourage intervention behavior using public service announcements (PSAs). Using a between‐subjects design of Christian Americans as the respondent pool, a religious symbol versus a control ad was utilized. Levels of religiosity were also measured and factors impacting the construct assessed. Findings revealed religiosity, the importance of religion in one's life, was the underlying motivator for highly religious people to act rather than a religious cue. Within religiosity, the perceived strength of faith to one's identity held greater value than church attendance and frequency of prayer. Theoretical implications are discussed as well as insights for people working in public service messaging.     

Supervisor Support and Organizational Commitment: The Role of Work–Family Conflict,Job Satisfaction,and Work–Life Balance

Building on conservation of resources theory and social exchange theory, the author examined the relationship between supervisor support and organizational commitment through work–family conflict, work–life balance, and the job satisfaction of employees working in the financial sector in Australia. The study comprised 305 employees recruited through an online survey. Results indicate that supervisor support is negatively related to work–family conflict. In turn, work–life balance and job satisfaction are negatively linked to work–family conflict. The results further show that both work–life balance and job satisfaction are positively related to organizational commitment. Theoretical and practical implications, as well as limitations, are discussed.
