Generic statements require little evidence for acceptance but have powerful implications

Generic statements (e.g., "Birds lay eggs") express generalizations about categories. In this paper, we hypothesized that there is a paradoxical asymmetry at the core of generic meaning, such that these sentences have extremely strong implications but require little evidence to be judged true. Four experiments confirmed the hypothesized asymmetry: Participants interpreted novel generics such as "Lorches have purple feathers" as referring to nearly all lorches, but they judged the same novel generics to be true given a wide range of prevalence levels (e.g., even when only 10% or 30% of lorches had purple feathers). A second hypothesis, also confirmed by the results, was that novel generic sentences about dangerous or distinctive properties would be more acceptable than generic sentences that were similar but did not have these connotations. In addition to clarifying important aspects of generics' meaning, these findings are applicable to a range of real-world processes such as stereotyping and political discourse.     

Une étude sur le rôle modérateur des traits de personnalité sur la relation entre les conditions de l’organisation du travail et la détresse psychologique

This study is about psychological distress lived by Canadian workers. Only a few studies considered personal traits in the comprehension of this phenomenon. This study aims to determine the moderator role of self-esteem, the sense of control and the sense of cohesion on the relation between the work organization conditions and psychological distress. Some longitudinal data (n=7338 workers) coming from five cycles (1994-2003) of the National Population Health Survey (NPHS) have been used to complete some multilevel analysis (n1=time and n2=individual). The results indicate that the sense of control and the sense of cohesion play a moderator role on the relation between some of the work organization conditions and the level of psychological distress.     

The Relationship Between Dropout and Outcome in Naturalistic Cognitive Behavior Therapy

Dropout from psychotherapy is frequent and limits the benefits patients can receive from treatment. The study of factors associated with dropout has the potential to yield strategies to reduce it. This study analyzed data from a large sample of adults (N = 1,092) receiving naturalistic cognitive behavioral therapy (CBT) to test the hypotheses that dropouts, as compared to completers, had (1) higher symptom severity at treatment termination, (2) a slower rate of symptom change during treatment, and (3) a higher odds that the therapist rated treatment as ending for reasons related to poor outcome. Results showed that although dropouts ended treatment with higher symptom severity than completers, dropouts and completers did not differ in their rate of symptom change during treatment, suggesting that dropouts had higher symptom severity at termination because they received fewer sessions of treatment, not because their symptoms changed at a slower rate. Dropout was also associated with a higher odds of having a therapist-rated termination reason indicating a poor outcome, suggesting that dropout is more likely if patients are dissatisfied with some aspect of the therapy outcome or process. These findings suggest that strategies for monitoring and enhancing patient satisfaction with the process and outcome of treatment may help patients stay in treatment longer and end treatment with fewer symptoms than if they had dropped out.     

Collective Efficacy as a Key Context in Neighborhood Support for Urban Youth

Neighborhood context, including the physical and social environment, has been implicated as important contributors to positive youth development. A transactional approach to neighborhood asserts that place and people are mutually constitutive; negative perceptions of place are intrinsically bound with negative portrayals of stigmatized groups, including youth. Adult perceptions of neighborhood youth may contribute to an increased sense of alienation and youth antisocial behavior. This study uses street‐intercept interviews with adults (N = 408) to examine the relationship between neighborhood conditions and adult support for neighborhood youth. A path model was used to examine the direct and indirect relationship of neighborhood constructs (safety, aesthetic quality, and walkability) on adult support for neighborhood youth. Neighborhood aesthetic quality and the walking environment were directly associated with adult support for youth, whereas perceived safety was indirectly associated. Collective efficacy partially explained these relationships. Findings support theorized relationships between people and places; improvements to neighborhood physical environment may directly impact resident adults’ perceptions of neighborhood young people.     

工作场所领导愤怒的有效性及其作用机制

领导愤怒(leader anger)作为最常见、最易被感受到的工作场所负面情绪之一, 对于改善工作关系、行为和绩效具有显著影响。然而, 已有文献关于领导愤怒阻碍还是促进领导有效性的观点存在许多争议, 对于领导愤怒为什么以及何种条件下影响领导有效性的问题尚不明确。在回顾工作场所领导愤怒概念起源和内涵特点的基础上, 从消极效应和积极效应双刃视角厘清了工作场所领导愤怒的有效性, 基于情绪即社会信息理论阐释了工作场所领导愤怒有效性的双路径中介机制, 并从个体/团队/组织三层面分析了领导愤怒有效性的边界条件。未来研究应从工作场所领导愤怒的概念和结构测量、事件前因和后果、中介机制、情境因素、研究方法和研究层面等方面进一步拓展。     

TRANSCENDING IRONY

A more complete understanding of the biocultural evolutionary origins of the concept of ought as developed by David Hume and G. E. Moore may lower the philosophical barrier between is and ought and provide new insights about the separations between the domains of religion and science. If this conjecture is correct, the resulting wisdom will help transcend a major source of irony that Philip Hefner has so aptly identified in his essay.
