The effects of expected and unexpected stress on inappropriate aggression in simulated police interventions.

Here we performed a before-after ABA-design study in police cadets (N = 82) to compare the effects of unexpected (event-triggered) and expected (anticipatory) stressors on aggression. On the first day of the study, participants filled in the Buss-Perry Aggression Questionnaire (BPAQ) and the Barratt Impulsiveness Scale (BIS) and were fitted with heart rate (HR) monitors, which remained attached till the end of the study. On day 2, they were instructed to perform a police intervention in a realistic training environment.

Risk Matrix for Violent Radicalization: A Machine Learning Approach.

Hypothesis-driven approaches identified important characteristics that differentiate violent from non-violent radicals. However, they produced a mosaic of explanations as they investigated a restricted number of preselected variables. Here we analyzed without a priory assumption all the variables of the "Profiles of Individual Radicalization in the United States" database by a machine learning approach.

The Four Faces of Competition: The Development of the Multidimensional Competitive Orientation Inventory.

To date, no short scale exists with established factor structure that can assess individual differences in competition. The aim of the present study was to uncover and operationalize the facets of competitive orientations with theoretical underpinning and strong psychometric properties. A total of 2676 respondents were recruited for four studies.

Narratives of effort among Chinese, Hungarian and Chinese immigrant students in Hungary.

The present study aimed to reveal the effect of migration processes on the conceptualisation of effort involving two cultures with different approaches towards effort: China with an effort-promoting mindset and Hungary with an effort-repressing mindset. In the study, narrative approach was used in cross-sectional design involving Chinese, Hungarian and Chinese immigrant students living in Hungary. Altogether 139 students-49 Hungarian, 47 Chinese, 43 Chinese immigrants-aged 13-15 years provided narratives on past personal effort.
