Language-mediated object categorization: A longitudinal study with 16- to 20-month-old Serbian-speaking children

This study addressed the development of language-mediated categorization longitudinally, on a sample of Serbian-speaking children aged 16–20 months. Twenty four children were tested 3 consecutive times on: categorization of unknown objects with a shared label and a similar shape; and categorization of unknown objects with a shared label, but no visual similarity. The task was embedded in a game-like activity which included real object manipulation, categorization of novel objects labeled with made-up names, and socio-pragmatic cues provided by the experimenter. Our results indicate that an average child develops the ability to categorize novel objects with a similar shape and a shared label around 16 months of age, whereas for novel objects with a shared label, but no visual similarity, this ability is acquired sometime between 18 and 20 months of age. Our results partly confirm research findings obtained in other languages, thus emphasizing the need for cross-linguistic and cross-cultural validation of all language-related developmental studies.     

The Effect of Locus of Control on University Students' Mental Health: Possible Mediation through Self-Esteem and Coping

The purpose of this study was to examine the effect of locus of control on university students' mental health and to examine possible mediational roles of self-esteem and coping. A total of 418 university students completed Rotters I-E Scale, Self-liking/self-competence Scale, Endlers Coping with Stressful Situations Scale and Depression, Anxiety and Stress Scale. The results showed that external locus of control, lower self-liking and self-competence, as well as less problem-focused and more emotion-focused coping predict more symptoms of depression, anxiety, and stress in university students. However, mediational analysis revealed that the effect of locus of control was fully mediated by self-esteem and coping, with self-liking and emotion-focused coping being the strongest mediators. Results suggest that beliefs about control affect beliefs about one's self-worth and coping strategies, which in turn can affect one's mental health.     

The role of retributive justice and the use of international criminal tribunals in post‐conflict reconciliation

Four experiments examined people's responses to intergroup violence either committed or suffered by their own group. Experiment 1 demonstrated that Serbs who strongly glorified Serbia were more supportive of future violence against, and less willing to reconcile with, Bosniaks after reading about Serbian victimization by Bosniaks rather than Serbian transgressions against Bosniaks. Replicating these effects with Americans in the context of American–Iranian tensions, Experiment 2 further showed that demands for retributive justice explained why high glorifiers showed asymmetrical reactions to ingroup victimization vs. perpetration. Again in the Serb and the American context, respectively, Experiments 3 and 4 demonstrated that post‐conflict international criminal tribunals can help satisfy victim group members' desire for retributive justice, and thereby reduce their support for future violence and increase their willingness to reconcile with the perpetrator group. The role of retributive justice and the use of international criminal justice in intergroup conflict (reduction) are discussed.     

Research Integrity Practices from the Perspective of Early-Career Researchers

Unavailability of published data and studies focused on young researchers in Europe and research integrity issues reveals that clear understanding and stance on this subject within European area is lacking. Our study provides information on attitudes and experiences of European researchers at early career stages (doctoral and postdoctoral level), based on a limited sample of respondents (n = 27). The study provides both quantitative and qualitative results for the examined issues. The data suggest that awareness and interest of the younger researchers surveyed in research integrity issues is high, however, it is often based on self-initiatives, with many of the respondents not having adequate training or any possibility to obtain it. Our attitude survey conducted within the European Council of Doctoral Candidates and Junior Researchers indicates that only 22 % of respondents had an opportunity to obtain relevant training (significantly less than in a study conducted in the U.S.), and that only one third believed that institutions and supervisors regularly paid attention to it. Further, we noted certain differences between disciplines. The study also reveals that many younger researchers felt they faced problems due to the misconduct of their senior colleagues and the existing institutional culture. The results of the study indicate a need for better prevention mechanisms, training and raising awareness activities. Preferably, junior researchers should be given an active role in shaping the integrity culture. It should be noted that the presented results should be considered in the context of the limitations stemming from the small-scale survey. This paper encourages further research activities on research integrity practices to provide stronger evidence on the attitudes and experiences of young researchers in Europe and other parts of the world.
