Rejection sensitivity as a mediator of the relationship between experienced rejection and borderline characteristics

Experiences of rejection in childhood play an important role in the etiology of borderline personality disorder (BPD). Additionally, individuals who report borderline symptoms report high levels of rejection sensitivity. The current study aimed to disentangle the relationship between experiences of rejection, rejection sensitivity and borderline characteristics. Therefore, we retrospectively assessed experiences of parental and peer rejection, collected data of self-reported rejection sensitivity and social support and prospectively investigated borderline characteristics in a sample of 193 students. Results indicated that rejection sensitivity fully mediated the previously significant relationship between experiences of parental rejection and borderline characteristics, whereas peer rejection maintained a significant effect on borderline traits. Social support was identified as a protective factor. Results indicated a crucial role of rejection sensitivity in borderline symptomatology.     

Relationship of Inglehart's and Schwartz's value dimensions revisited

This study examines the relationship between Inglehart's and Schwartz's value dimensions—both at the individual and the country levels. By rotating one set of items towards the other, we show that these value dimensions have more in common than previously reported. The ranking of countries (N = 47) based on Schwartz's Embeddedness—Autonomy and the Survival—Self‐Expression dimensions reached a maximum of similarity, r = .82, after rotating Inglehart's factor scores 27 degrees clockwise. The correlation between the other pair of dimensions (Schwartz's Hierarchy‐Mastery—Egalitarianism‐Harmony and Inglehart's Traditional—Secular‐Rational values) was near zero before and after rotation. At the individual level (N = 46,444), positive correlations were found for Schwartz's Conservation—Openness dimension with both of Inglehart's dimensions (Survival—Self‐Expression and Traditional—Secular‐Rational values). The highest correlation with this Schwartz dimension was obtained at the Secular‐Rational/Self‐Expression diagonal, r = .24, after rotating the factor scores 45 degrees clockwise. We conclude that Schwartz's and Inglehart's originally proposed two‐dimensional value structures share one dimension at the country level and some commonality at the individual level, whereas the respective other pair of dimensions seem to be more or less unrelated.     

Analyse Préliminaire des Qualités Psychométriques d’une Version Française du Work Design Questionnaire

The Work Design Questionnaire (Morgeson & Humphrey, 2006) assesses numerous work characteristics. The present research was designed to assess the psychometric properties of a French version of this tool (i.e., WDQ-F) through the following analyses: confirmatory factor analysis, reliability, and nomological validity with work satisfaction, engagement and burnout. In Studies 1 and 2, results of confirmatory factor analyses showed that the fit indices for the 21-dimension model were poor and that seven items displayed low factor loadings. In Study 2, results showed that a reduced version of the WDQ-F (71 items) demonstrated better psychometric properties than the 77-item version of the questionnaire. In addition, correlation analyses provided support for the nomological validity of the WDQ-F.     

表情信息特征变化对自闭症儿童面孔视觉扫描的影响

实验以眼动追踪技术为手段,考察自闭症儿童对不同信息特征表情图片的视觉扫描特征,探讨自闭症表情加工的机制。结果发现：1、看真人表情时,自闭症儿童对高兴、悲伤的整脸扫描时间无显著差异,均高于愤怒和恐惧,对愤怒的整脸扫描时间高于恐惧;2、看真人表情时自闭症儿童对高兴、悲伤表情的眼睛区域和嘴巴区域扫描时间无差异,对恐惧和愤怒的嘴巴区域扫描时间显著多于眼睛区域;3、信息特征削弱对自闭症儿童面孔表情视觉扫描产生了影响,随着削弱程度的增加,自闭症儿童对表情图片的嘴巴区域扫描时间增加,对眼睛区域的扫描时间减少。根据实验结果,认为自闭症儿童对表情的加工主要受到表情信息特征的影响,随着信息特征的变化,会对视觉注意进行调整,以获得对表情的充分加工。     

The relationship between anti-gay prejudice and the categorization of sexual orientation

A relatively large literature has demonstrated that sexual orientation can be judged accurately from a variety of minimal cues, including facial appearance. Untested in this work, however, is the influence that individual differences in prejudice against gays and lesbians may exert upon perceivers’ judgments. Here, we report the results of a meta-analysis of 23 unpublished studies testing the relationship between anti-gay bias and the categorization of sexual orientation from faces. Aggregating data from multiple measures of bias using a variety of methods in three different countries over a period of 8 years, we found a small but significant negative relationship between accuracy and prejudice that was homogeneous across the samples tested. Thus, individuals reporting higher levels of anti-gay bias appear to be less accurate judges of sexual orientation.     

Controllability of Partially Automated Driving functions – Does it matter whether drivers are allowed to take their hands off the steering wheel?

Different motor vehicle manufacturers have recently introduced assistance systems that are capable of both longitudinal and lateral vehicle control, while the driver still has to be able to take over the vehicle control at all times (so-called Partial Automation). While these systems usually allow hands-free driving only for short time periods (e.g., 10 s), there has been little research whether allowing longer time periods of hands-off driving actually has a negative impact on driving safety in situations that the automation cannot handle alone. Altogether, two partially automated assistance systems, differing in the permitted hands-off intervals (Hands-off system vs. Hands-on system, n = 20 participants per assistance condition, age 25–70 years) were implemented in the driving simulation with a realistic take-over concept. The Hands-off system is defined by having a permitted hands-off interval of 120 s, while the Hands-on system is defined by a permitted hands-off interval of 10 s. Drivers’ reactions at a functional system limit were tested under conditions of high ecological validity: while driving in a traffic jam, participants unexpectedly encountered a time-critical situation, consisting of a vehicle at standstill that appeared suddenly and required immediate action. A visual-auditory take-over request was issued to the drivers. Regardless of the hands-off interval, all participants brought the vehicle to a safe stop. In spite of a stronger brake reaction with the Hands-on system, no significant differences between assistance levels were found in brake reaction times and the criticality of the situation. The reason for this may be that most of the drivers kept contact with the steering wheel, even in the Hands-off condition. Neither age nor prior experience with ACC was found to impact the results. The study thus demonstrates that permitting longer periods of hands-off driving does not necessarily lead to performance deficits of the driver in the case of take-over situations, if a comprehensive take-over concept is implemented.     

Intrinsic motivation and individual deliberate practice are reciprocally related: Evidence from a longitudinal study of adolescent team sport athletes

ObjectiveThere is limited understanding of how sport motivation is associated with deliberate practice in youth team sport athletes. Therefore, the aim of this study was to examine prospective associations between intrinsic motivation and individual deliberate practice in specializing team sport athletes.DesignLongitudinal.MethodEstonian adolescent team sport athletes (N = 163; M_age – 13.6 years at the beginning of study) completed the Sport Motivation Scale and training diary across a 12-month period.ResultsBoth individual deliberate practice and intrinsic motivation increased over the 1-year period. Greater baseline intrinsic motivation predicted subsequent individual deliberate practice and greater initial individual deliberate practice predicted greater subsequent intrinsic motivation. The bidirectional relationship between athletes intrinsic motivation and individual deliberate practice were replicated across both time lags.ConclusionThe findings have significant implications for the importance placed on intrinsic motivation as a means of increasing of individual deliberate practice as well being an important outcome variable in specializing team sport athletes.     

Work engagement during life-span: The role of interaction outside the organization and task significance

Growing proportion of older employees in the workforce has pushed scholars and managers to examine the changes of individual work-related attitudes and behavior during the life-span and accordingly reconsider work design to sustain the engagement of aging workforces. This study contributes to ambiguous previous findings by investigating age–work engagement linkage and moderating effects of such job characteristics as employees' perceived task significance and interaction outside organization. Survey of bank employees revealed an overall positive linear effect of age on work engagement; task significance was further positively related to work engagement. Although the direct impact of interaction outside the organization to work engagement was not found, the interaction outside the organization moderated the relationship between age and work engagement: older employees with more external interactions reported higher engagement levels than older employees with fewer interactions. Work engagement was highest for older employees who experienced more interaction outside the organization, or perceived their work as significant or both. There was no positive effect of age on work engagement for employees with both lower levels of interaction outside organization and lower task significance.
