Why do leaders engage in destructive behaviours? The role of leaders’ working environment and stress

Complementing previous research on antecedents of destructive leadership, we examined the role of work stressors in the emergence of active and passive destructive leadership behaviours. Building on conservation of resources theory, we examined direct and indirect relations between leaders’ perceptions of workload, role ambiguity and intragroup conflict on ratings of their own destructive leadership, as well as mediating paths through perceived stress. We used a two-wave survey design consisting of a random sample of 1311 managers. Structural equation modelling revealed that work stressors were only related to passive forms of destructive leadership, whereas personality was related to both active and passive forms of destructive leadership. Implications for research and practice are discussed.     

Associations Between Preschoolers' Social–Emotional Competence and Preliteracy Skills

Identifying and understanding the predictors of preliteracy skills can set the stage for success in a child's academic career. Recent literature has implicated social–emotional competence as a potential component in helping children learn preliteracy skills. To further understand the role of social–emotional competence in preliteracy, the associations between various social–emotional competencies and preliteracy skills in 91 preschool children attending seven Head Start classrooms were examined. Results of structural equation modelling indicated that preschoolers' expressiveness/regulation (angry/aggressive, cooperative/sensitive or anxious/withdrawn) and emotion knowledge predicted preliteracy performance (alphabet knowledge and print and phonological awareness), above and beyond gender, age, maternal education, attentional abilities and classroom emotional support. These findings serve to broaden the research surrounding social–emotional competence and highlight its association with academic readiness. Copyright © 2015 John Wiley & Sons, Ltd.     

Sex Differences in Furniture Assembly Performance: An Experimental Study

This study examined sex differences in furniture assembly performance by manipulating the availability of instructions. Two groups of participants with an equal number of men and women assembled a kitchen trolley from IKEA. One group received step‐by‐step instructions, and the other group a diagram of the finished product. In addition, individual spatial ability was measured with the mental rotation test (MRT) and added to the analyses. Our results showed that men assembled the furniture faster (d = 0.78) and more accurately (d = 0.65) than women. Overall, participants performed better with step‐by‐step instructions than without (d = 0.61), and the time spent on instructions was negatively related to MRT scores, r = ?.428, p = .006. Aside from the time spent on instructions, women assembled the furniture nearly as fast as men did, and the sex difference in assembly score could be explained by differences in individual spatial ability.

Die neuen Klassifikationen von epileptischen Anfällen und Epilepsien

In 2010 the classification and terminology committee of the International League Against Epilepsy (ILAE) presented a revised proposal for the classification of epileptic seizures and epilepsy, which is also available as a German translation. In 2016 this commission presented an operational classification of epileptic seizures and new concepts for the classification of epilepsy. The essential amendments and aspects of this new classification system in comparison to the previous classification of epileptic seizures and epilepsy are briefly summarized and exemplified by two case reports.     

Can we shield ourselves from task disturbance by emotion-laden stimulation?

Emotion-laden stimuli can disturb information processing in an unrelated cognitive task. We investigated the possibilities and limitations for shielding from such disturbance. Participants performed a simple categorization task while being simultaneously exposed to negative, neutral, and positive pictures. Performance dropped with negative pictures, relative to positive and neutral stimuli. Unlike Stroop or Simon interference effects, this negativity-based disturbance did not reduce as a function of previous experience of disturbance (Exp. 1) or of announcement of such disturbance on a trial-by-trial basis (Exps. 2 and 3). We found hints of a reduction of negativity-based disturbance, however, when negative stimulation occurred with high list-wide probability (Exp. 4). These observations suggest that the control of negativity-based task disturbance might be possible in a sustained manner, but that it is severely limited when operating in a transient, moment-to-moment manner.     

Influence of judges' behaviors on perceived procedural justice

The influence of judges' behaviors on procedural justice was analyzed in a field study, observing the judges' behaviors during n = 129 trials and assessing the defendants and the audiences' justice perceptions. The observed judicial behavior was unrelated to the defendants' justice perceptions. However, the more respectful the judge treated the defendants, the fairer the audience perceived the trial. In general, the effect size of the relationship between observational measures and subjective justice ratings was small in comparison to the relationship within defendants' or audiences' ratings. There were striking differences in the justice perception between the two data sources, namely defendants and audience. Thus, the source matters, and to avoid a same‐source bias, should be taken into account when analyzing justice perceptions.     

Contextual modulation of prime response retrieval processes: Evidence from auditory negative priming

Contextual similarity between learning and test phase has been shown to be beneficial for memory retrieval. Negative priming is known to be caused by multiple processes; one of which is episodic retrieval. Therefore, the contextual similarity of prime and probe presentations should influence the size of the negative priming effect. This has been shown for the visual modality. In Experiment 1, an auditory four-alternative forced choice reaction time task was used to test the influence of prime-probe contextual similarity on negative priming and the processes underlying the modulation by context. The negative priming effect was larger when the auditory context was repeated than when it was changed from prime to probe. The modulation by context was exclusively caused by an increase in prime response retrieval errors in ignored repetition trials with context repetition, whereas repeating only the context but not the prime distractor did not lead to an increase in prime response retrieval. This exact pattern of results was replicated in Experiment 2. The findings suggest that contextual information is integrated with prime distractor and response information. Retrieval of the previous episode, including prime distractor, prime response, and context (event file), can be triggered when the former prime distractor is repeated, whereas a context cue alone does not retrieve the event file. This suggests an event file structure that is more complicated than its usually assumed binary structure.
