睡眠时间参数对学前儿童问题行为的影响:消极情绪性的调节作用

本研究以338名学前儿童为被试,采用母亲报告法探究了学前儿童睡眠时间与问题行为之间的关系,以及儿童消极情绪性的调节作用。结果发现：（1）睡眠总时长对儿童内化和外化问题行为的主效应显著,而睡眠总时长与消极情绪性对儿童内化和外化问题行为的交互作用不显著;（2）夜间睡眠比对儿童内化问题行为的主效应显著,对儿童外化问题行为的主效应不显著;夜间睡眠比与消极情绪性对儿童内化问题行为的交互作用显著,即对高消极情绪性的儿童,夜间睡眠比能够显著负向预测其内化问题行为,而对低消极情绪性的儿童,夜间睡眠比对其内化问题行为的预测并不显著;夜间睡眠比与消极情绪性对儿童外化问题行为的交互作用不显著。     

父母心理控制与青少年冒险行为的非线性关系:自尊的调节作用

本研究旨在探讨父、母亲心理控制与青少年冒险行为是否存在非线性关系,以及是否受青少年自尊的调节。采用父母心理控制量表、自尊量表和青少年冒险行为量表对北京石景山区、山东省德州市和河北省邯郸市的四所普通中学七至九年级共2520名（男生1226人,女生1294人）学生进行调查。结果发现：青少年冒险行为与父亲心理控制呈U型曲线关系,而与母亲心理控制呈倒U型关系。调节效应分析发现,父、母亲心理控制与青少年冒险行为的非线性关系仅体现在中低等自尊青少年上,而高自尊青少年的冒险行为与父母心理控制无关。这表明,青少年自尊调节了父、母亲心理控制对其冒险行为的作用,父、母亲相同教养行为对中低等自尊青少年的冒险行为可能有不同的作用。     

Can emotional bonding be a liability? Status striving as an intervening mechanism in affective commitment and negative work behaviors relationship

IntroductionThe dark side of affective commitment has been ignored in the past literature on organizational commitment.ObjectivesUsing the tenants of moral self-licensing theory, we examined how affective commitment can cause negative outcomes. We hypothesized that affective commitment leads to unethical pro-organizational behaviors, careerism and counter-productive work behaviors through increased urge for status striving.Methods and resultsA multi-wave and two-source data was obtained (n = 306) from employees and their peers working in the service sector of Pakistan. Employing structural equation modelling (SEM) analysis our results indicate that high levels of affective commitment might unleash status striving which further creates unethical pro-organizational behaviors, careerism and CWBs.ConclusionThe current study opens up a new side in the affective commitment literature by examining status striving as an underlying mechanism through which affective commitment reveals its deleterious consequences for employees.     

Bioinspired decision-making for a socially interactive robot

Nowadays, robots and humans coexist in real settings where robots need to interact autonomously making their own decisions. Many applications require that robots adapt their behavior to different users and remember each user’s preferences to engage them in the interaction. To this end, we propose a decision making system for social robots that drives their actions taking into account the user and the robot’s state. This system is based on bio-inspired concepts, such as motivations, drives and wellbeing, that facilitate the rise of natural behaviors to ease the acceptance of the robot by the users. The system has been designed to promote the human-robot interaction by using drives and motivations related with social aspects, such as the users’ satisfaction or the need of social interaction. Furthermore, the changes of state produced by the users’ exogenous actions have been modeled as transitional states that are considered when the next robot’s action has to be selected. Our system has been evaluated considering two different user profiles. In the proposed system, user’s preferences are considered and alter the homeostatic process that controls the decision making system. As a result, using reinforcement learning algorithms and considering the robot’s wellbeing as the reward function, the social robot Mini has learned from scratch two different policies of action, one for each user, that fit the users’ preferences. The robot learned behaviors that maximize its wellbeing as well as keep the users engaged in the interactions.     

情绪调节自我效能感与心理健康的交叉滞后研究

摘 要：对531名青少年进行为期五个月的追踪,运用交叉滞后回归分析考察积极、沮丧、生气三种情绪调节自我效能感与心理健康（问题行为、抑郁和生活满意度）间的相互影响。结果：T1积极情绪调节自我效能感不能预测T2问题行为、抑郁和生活满意度;T1沮丧情绪调节自我效能感显著预测T2抑郁水平;T1生活满意度和抑郁显著预测T2生气情绪调节自我效能感。结论：高沮丧情绪调节自我效能感能保护青少年处于“低抑郁状态”,而生气情绪调节自我效能感更容易受到个体生活满意度和抑郁水平的影响,是青少年处于不良心理状态下的易感效能。     

越老越风险规避吗？——年龄对冲动性预测决策行为的调节效应

年老化伴随着风险承担倾向的改变,而决策行为受冲动性的影响是否受到年龄的调节尚不清楚。研究采用两种不同类型的决策任务以及Barratt冲动性量表,考察老年人风险承担在自我报告和决策行为上的改变。结果显示老年人在剑桥博弈任务中更加风险寻求而在模拟充气球任务中更加风险规避。同时冲动性可以显著预测模拟充气球的行为,且该预测受到年龄的调节。研究结果提示,老年人并不是单一的更加风险规避或者风险寻求,而是与任务特异性相关。同时,冲动性可以较好的预测年轻人的决策行为,而对老年人的决策行为没有预测作用。     

Motives to Report Stalking Cases to the Police: A Comparison Between a Large City and a Small Town in Italy

This study aimed to analyze the cases reported to police by women who were victims of stalking. The use of police offense records is well known in investigations of victims of this phenomenon as well as other violent crimes (e.g., domestic violence). The objective was to compare the 3 motives (own safety, other safety, change habits) indicated by victims in reporting the cases to police as recorded in case files. For each motive, a comparison was made of the characteristics of victims and stalkers, the nature of the relationship between the victims and stalkers, and the characteristics of the stalking campaign, the stalker’s behaviors, the consequences to the victims, and coping strategies. This information was reported by victims to police in a large city and small town in Italy. The comparison showed that victims in large cities were less prone to report stalking cases to the police than victims in small towns. Differences addressed the duration of the stalking campaign, the behaviors involved, the consequences, and the coping strategies adopted. Police forces could benefit from the results of this research in defining both training courses for police officers and prevention courses for the general population.     

Screening out accident-prone Iranian drivers: Are their at-fault accidents related to driving behavior?

To provide a scientific background in road safety domain a better understanding of human risk factor is crucial. The aims of the present study were the following: (1) developing an accident prediction model for estimating the at-fault accidents of drivers (2) controlling for the regression-to-the-mean and screening out the accident-prone drivers (3) identification of significant behavioral predictors in at-fault accident occurrences and delving into the relationship between the aberrant driving behaviors and at-fault accidents of those identified as accident-prone. A questionnaire survey compiling various measures of personality type, aberrant driving behavior, demographic and accident history information of 1762 Iranian drivers was conducted in which 1375 male and 387 female participants were of the average age of 35.6 (S.D. = 11.987). To analyze the obtained data, the generalized linear modeling (GLM) approach was taken resulting in four models with various independent variables. The results indicated that age, gender, education level, years of active driving, and especially exposure had an effect on drivers’ at-fault accidents while there was no discernible effect from income level, personality type and area of residence. In the screening procedure, 715 drivers were identified as accident-prone. Behavioral comparison analyses indicated that the lapses, errors, ordinary and aggressive violations are different for the accident-prone drivers. A comparison between the accident-prone and non-accident-prone drivers revealed that the ordinary violations have considerably higher effect than the others on at-fault accidents. Implications of the results are discussed with regard to insurance policies and education interventions.     

Bidirectional relations between different forms of prosocial behaviors and substance use among female college student athletes

Bidirectional, longitudinal relations between alcohol and marijuana use and prosocial behaviors in women college student athletes were examined. Participants were 187 female college students (M_age = 19.87 years; 91% White) who completed questionnaires on their use of marijuana and alcohol, and six forms of prosocial behaviors across 6 years (2004–2010). The findings yield overall evidence that earlier marijuana use predicted lower levels of most specific forms of prosocial behaviors for women athletes in later young adulthood. Early expressions of altruistic behaviors predicted less marijuana use in later young adulthood. Expression of public prosocial behaviors early in young adulthood predicted higher levels of hazardous drinking in late young adulthood. These novel findings have important implications for links between prosocial development and substance use in women college athletes.     

Within-person and between-people variability in personality dynamics: Knowledge structures,self-efficacy,pleasure appraisals,and the Big Five

We investigated within-person co-variations from the perspective of knowledge-and-appraisal theories of personality. Knowledge structures were idiographically assessed as personal beliefs on the relevance of personality characteristics in facilitating successful actions in interpersonal situations. Three main findings emerged. First, beliefs of situational relevance of self-defining strengths and weaknesses show additive effects in accounting for intra-individual variability in contextualized self-efficacy appraisals. Secondly, between-person variability in Extraversion moderates within-person co-variation between self-efficacy and knowledge structures. Thirdly, self-efficacy mediates the impact of knowledge structures on perceived likelihood of performing the interpersonal behaviors in the future, after controlling for rated frequency of the same behaviors in the past. Overall, the present findings suggest that within-person and between-person approaches are complementary and need to be integrated.
