Performance implications of leader briefings and team-interaction training for team adaptation to novel environments

The authors examined how leader briefings and team-interaction training influence team members' knowledge structures concerning processes related to effective performance in both routine and novel environments. Two-hundred thirty-seven undergraduates from a large mid-Atlantic university formed 79 three-member tank platoon teams and participated in a low-fidelity tank simulation. Team-interaction training, leader briefings, and novelty of performance environment were manipulated. Findings indicated that both leader briefings and team-interaction training affected the development of mental models, which in turn positively influenced team communication processes and team performance. Mental models and communication processes predicted performance more strongly in novel than in routine environments. Implications for the role of team-interaction training, leader briefings, and mental models as mechanisms for team adaptation are discussed.

Self-harming behaviours of asylum seekers and refugees in Europe: A systematic review

The increasing number of asylum seekers and refugees in Europe calls for even more professionals to take care of refugees' mental health. Although different studies claim that migration could be a potential risk factor for self-harming behaviours, an in-depth exploration of the presence and characteristics of self-harm in the context of asylum is needed. In accordance with PRISMA guidelines, a systematic review was conducted across the databases Scopus, PubMed, Web of Knowledge and PsycArticles, regarding the main features of self-harming behaviour among refugees in Europe. Twelve articles and 3 main trajectories were identified: (1) A context at-risk: self-harm and detention centres; (2) A target at-risk: self-harm and unaccompanied minors; (3) A comparison between the mental health of asylum seekers and natives. Research on this topic in Europe is still underdeveloped and disorganised. Studies have mainly carried out wider quantitative investigations on mental health, usually overlapping self-harm with suicide. Detention centres emerged as the most widely investigated context and the one with the highest risk for self-harming behaviours. Instead, unaccompanied minors emerged as a particularly vulnerable category. Research in this field should be improved, combining quantitative and qualitative methods for a deeper understanding of the meanings of self-harm across cultures.     

Linking servant leadership to positive deviant behavior: The mediating role of self-determination theory

How can servant leadership focused primarily on developing employees help them to become more ethical and prosocial, and to achieve positive results reaching beyond mere compliance with their tasks? More specifically, we propose that servant leadership may influence employees to engage in positive deviant behavior (PDB), meaning non-conforming behavior that is positive and ethical. Using self-determination theory (SDT), our research examines the effect of perceived servant leadership on the adoption of PDB by employees, mediated by basic psychological needs satisfaction and intrinsic motivation. To this end, we conducted a quantitative study of 344 French employees’ answers to an online survey. Structural equation modeling results indicated that the relationship between perceived servant leadership and innovative PDB is strongly predicted by SDT. Intrinsic motivation mediates the relationship between perceived servant leadership, satisfaction of basic psychological needs, and innovative PDB. Several limitations and implications will be discussed.     

Adaptive Logic Characterizations of Input/Output Logic

We translate unconstrained and constrained input/output logics as introduced by Makinson and van der Torre to modal logics, using adaptive logics for the constrained case. The resulting reformulation has some additional benefits. First, we obtain a proof-theoretic (dynamic) characterization of input/output logics. Second, we demonstrate that our framework naturally gives rise to useful variants and allows to express important notions that go beyond the expressive means of input/output logics, such as violations and sanctions.     

Assessing the Approximate Number System: no relation between numerical comparison and estimation tasks

Whether our general numerical skills and the mathematical knowledge that we acquire at school are entwined is a debated issue, which many researchers are still striving to investigate. The findings reported in the literature are actually inconsistent; some studies emphasized the existence of a relationship between the acuity of the Approximate Number System (ANS) and arithmetic competence, while some others did not observe any significant correlation. One potential explanation of the discrepancy might stem from the evaluation of the ANS itself. In the present study, we correlated two measures used to index ANS acuity with arithmetic performance. These measures were the Weber fraction (w), computed from a numerical comparison task and the coefficient of variation (CV), computed from a numerical estimation task. Arithmetic performance correlated with estimation CV but not with comparison w. We further investigated the meaning of this result by taking the relationship between w and CV into account. We expected a tight relation as both these measures are believed to assess ANS acuity. Crucially, however, w and CV did not correlate with each other. Moreover, the value of w was modulated by the congruity of the relation between numerical magnitude and non-numerical visual cues, potentially accounting for the lack of correlation between the measures. Our findings thus challenge the overuse of w to assess ANS acuity and more generally put into question the relevance of correlating this measure with arithmetic without any deeper understanding of what they are really indexing.     

Validating the B‐Scan Self: A self‐report measure of psychopathy in the workplace

The surging interest in corporate psychopathy has underscored the need for a reliable and valid measure of psychopathic features that is suitable for research in organizational settings. The B‐Scan Self is a new self‐report measure of corporate psychopathy that was developed with Hare's Psychopathy Checklist‐Revised (PCL‐R) as a framework. Validity studies, using two independent Mechanical Turk samples, were designed to examine its factor structure and validity. Results indicated that B‐Scan Self facets were internally consistent and unidimentional and strongly related to another self‐report measure of psychopathy (SRP‐III). Confirmatory factor analyses supported a reliable fifteen facets and four‐factor model consistent with the PCL‐R four‐factor model of psychopathy. Furthermore, B‐Scan Self facets were positively correlated with the Dark Triad of personality traits and negatively correlated with FFM traits of Agreeableness and Conscientiousness. More importantly, B‐Scan Self facets presented the same pattern of correlations with FFM traits as the SRP‐III and different patterns than the two other Dark Triad measures. Although this constitutes the first validation study of the B‐Scan Self and more research is needed, we believe that these results are encouraging and that the B‐Scan Self provides an opportunity to study psychopathic features through the measure of work‐related behavior.     

Colour and emotion: children also associate red with negative valence

The association of colour with emotion constitutes a growing field of research, as it can affect how humans process their environment. Although there has been increasing interest in the association of red with negative valence in adults, little is known about how it develops. We therefore tested the red–negative association in children for the first time. Children aged 5–10 years performed a face categorization task in the form of a card‐sorting task. They had to judge whether ambiguous faces shown against three different colour backgrounds (red, grey, green) seemed to ‘feel good’ or ‘feel bad’. Results of logistic mixed models showed that – as previously demonstrated in adults – children across the age range provided significantly more ‘feel bad’ responses when the faces were given a red background. This finding is discussed in relation to colour–emotion association theories.
