The challenging pupil in the classroom: the effect of the child on the teacher

Teaching children requires effort, and some children naturally require more effort than others. In this study, we tested whether teacher effort devoted to individual children varies as a function of each child's personal characteristics. In a nationwide longitudinal study of 1,102 pairs of twins followed for 7 years, between the ages of 5 and 12 years, we asked teachers about the effort they invested in each child in our study. We found that teacher effort was a function of heritable child characteristics, that a child's challenging behavior assessed at 5 years of age predicted teacher effort toward the same child at 12 years of age, and that challenging child behavior and teacher effort share a common etiology with respect to children's genes. We found that child effects accounted for a significant proportion of variance in teacher effort, but also observed variation in effort exerted by teachers that could not be attributed to children's behavior. Treating children who exhibit challenging behavior and enhancing teachers' skills in managing such behavior could increase the time and energy teachers have to deliver their curriculum in class.     

A comparison of impulsivity and sensation seeking in pathological gamblers and skydivers

The aim of this study was to compare pathological gamblers and skydivers in relation to measures of impulsivity and sensation seeking. The Eysenck Impulsivity Scale - Narrow Impulsiveness Subscale and the Arnett Inventory of Sensation Seeking were administered to pathological gamblers (n = 29), skydivers (n = 93), and a control group (n = 43). A two-way multivariate analysis of variance was conducted to explore differences in impulsivity and sensation seeking between the groups and possible group by gender and group by age interaction effects. The significant effects were further investigated using follow-up univariate analysis of variance. The results showed significant main effects of Group, Gender and Age, and a significant Group by Gender interaction effect. The results showed no statistically significant differences in impulsivity between pathological gamblers and skydivers; however, both groups scored higher than the controls. The skydivers scored higher compared to the pathological gamblers and controls on both sensation seeking subscales. Pathological gamblers scored higher than the controls on the subscale Need for Stimulus Intensity, although lower than the controls on the subscale Need for Novelty. We conclude that skydivers and pathological gamblers do not seem to differ in terms of impulsivity, but that the two groups differ in terms of sensation seeking. Skydivers are hence characterized by more sensation seeking compared to pathological gamblers. Skydiving, as opposed to pathological gambling, is not considered a psychiatric disorder, and skydiving may represent a more non-pathological way to fulfill the need for stimulus intensity.     

EEG theta phase coupling during executive control of visual working memory investigated in individuals with schizophrenia and in healthy controls

In healthy humans, it has been shown that executive functions are associated with increased frontal-midline EEG theta activity and theta phase coupling between frontal and posterior brain regions. In individuals with schizophrenia, central executive functions are supposed to be heavily impaired. Given that theta phase coupling is causally involved in central executive functions, one would expect that patients with an executive function deficit should display abnormal EEG theta synchronization. We therefore investigated executive functioning in 21 healthy controls and 21 individuals with schizophrenia while they performed a visuospatial delayed match to sample task. The task required either high executive demands (manipulation of content in working memory [WM]) or low executive demands (retention of WM content). In addition, WM load (one vs. three items) was varied. Results indicated higher frontal theta activity for manipulation processes than for retention processes in patients with schizophrenia, as compared with healthy controls, independently of WM load. Furthermore, individuals with schizophrenia revealed a reduction in theta phase coupling during early stages of the delay period for retention, as well as for manipulation processes at high-WM loads. Deviations in theta phase coupling in individuals with schizophrenia were mainly characterized by aberrant fronto-posterior connections, but also by attenuated posterior connections during manipulation of high-WM load. To conclude, fronto-parietal theta coupling seems to be substantially involved in executive control, whereas frontal theta activity seems to reflect general task demands, such as deployment of attentional resources during WM.     

Falsche Geständnisse

Although false confessions would seem to run counter to their own interests, innocent suspects do occasionally admit to having committed even serious crimes. This article describes individual differences in susceptibility to interrogative influence and mechanisms through which interrogation tactics can induce false confessions. It will also show that there is no simple way of distinguishing false from true confessions, which is partly due to the lack of verbatim records of interviews with suspects. In some cases false confessions can even negatively impact on the gathering and evaluation of further evidence and in turn this seemingly independent evidence seems to validate the false confession if this is later retracted. Psychological expertise may well help to clarify individual cases; however, any uncritical transfer of the credibility assessment developed to evaluate witness testimony, without taking the specific conditions of interviews with suspects into account, may well lead to false results.     

Quality of management by objectives,task-related stressors,and non-task-related stressors as predictors of stress and job satisfaction among teleworkers

This study examined the effects of management behaviour together with jobrelated and non-job-related stressors on stress experience and job satisfaction among teleworkers. Fifty-four participants were full- or part-time teleworkers, and eighteen participants were members of a nonteleworking control group with comparable working tasks recruited from the same companies. Self-report measures of quality of MBO, task-related stressors, and non-job-related stressors (predictors) were collected, together with measures of participants' stress experience and job satisfaction (criteria). The three predictor variables represented rather independent stress factors. Consistent with expectations, non-job-related stressors were higher for teleworkers working predominantly at home compared to office-centred teleworkers and nonteleworking controls. Moreover, regression analyses indicated significant effects of quality of MBO and non-job-related stressors on teleworkers' stress experience and job satisfaction. Occupational health and management implications of these results for preventive and prospective aspects of telework design are discussed.     

Modernization and the logic of interorganizational networks

In this paper an attempt is made to widen the perspective under which interorganizational networks are generally seen. It is argued that both in the economy and in policy making, network phenomena are in fact becoming more prominent. This is linked to functional differentiation, a core process of societal modernization, which implies the existence of partly autonomous societal subsystems. Their emergence is closely connected with the ascendance of formal organizations, which in turn enjoy a certain measure of autonomy. In this structural context, interorganizational network following a logic of negotiation, which extends to “constitutional” issues can provide a solution to coordination problems typical of modern societies. Her research interests include sociological macro-theory, comparative social and political research, organizational and administrative sociology, and sociology of technology.     

The good,the bad and the central of group identification: Evidence of a U‐shaped quadratic relation between in‐group affect and identity centrality

The present research investigates the interrelation between two widely studied dimensions of social group identity—in‐group affect and centrality. Specifically, we test the validity of a quadratic curvilinear relation between in‐group affect and identity centrality. We propose that group members who feel either decidedly positive affect or decidedly negative affect towards their group are more likely to feel that their identity is a central component of their self‐concept relative to group members with neutral affect. We find evidence for a quadratic relation between in‐group affect and identity centrality with respect to people's cultural identity (N = 512), ethnic identity (N = 462), religious identity (N = 61, N = 384) and racial identity (N = 3600, N = 2400). Theoretical and practical implications for the measurement and conceptualization of group identification are discussed. Copyright © 2016 John Wiley & Sons, Ltd.
