Dispositional pessimism,defensive pessimism and optimism: The effect of induced mood on prefactual and counterfactual thinking and performance

This study analyses the extent to which dispositional pessimists differ from defensive pessimists and optimists in the generation of prefactual and counterfactual thoughts and in their performance in an anagram task, under different conditions of induced mood. Dispositional pessimists performed in a similar manner in all circumstances, recording an equal number of prefactual thoughts. By contrast, optimists and defensive pessimists optimised their performance under positive and negative conditions, respectively. It should be noted that after performing this task, the number of counterfactual thoughts expressed by dispositional pessimists varied according to mood states. The results are discussed in terms of the rigidity of the generalised expectations of dispositional pessimism.     

MANAGING DIVERSITY: HOW ORGANIZATIONAL EFFORTS TO SUPPORT DIVERSITY MODERATE THE EFFECTS OF PERCEIVED RACIAL DISCRIMINATION ON AFFECTIVE COMMITMENT

Using the interactional model of cultural diversity, we examined whether the negative effects of perceived racial discrimination on affective commitment can be mitigated by perceived organizational efforts to support diversity. Across 3 studies, we found that perceptions of workplace racial discrimination are negatively related to affective commitment. In 2 out of 3 studies, this negative relationship was attenuated as employees perceived more organizational efforts to support diversity. Studies 1 (mostly Whites) and 2 (mostly Hispanics) showed that organizational efforts to support diversity attenuate the negative effects of perceived racial discrimination on affective commitment. However, in Study 3 (African Americans), results showed that when organizational efforts to support diversity are high, the negative relationship between perceived racial discrimination and affective commitment became stronger. Studies 2 and 3 also extended these results by showing that the interaction of perceived racial discrimination and organizational efforts to support diversity indirectly influences turnover intent.     

Comparative analysis of the perception of school violence in teachers, pupils, and families

The main aim of the present study is to analyze the opinion of pupils, families and teachers in four European countries (Spain, Hungary, Austria and the Czech Republic) on the prevalence of violent behavior and other problematic aspects related to coexistence in schools, and on the way in which individuals are personally affected by them. For this purpose, a single instrument was used. From the results obtained it emerges, first of all, that there are significant differences depending on who is analyzing the school problems. Generally, families perceive the problems analyzed as less common and feel less affected by them personally. Hungary was considered to be the country with the lowest levels of school violence. Pupils indicate their concern about the high levels of lack of motivation or boredom, whilst teachers are more preoccupied about the serious problems of coexistence, due in particular to the presence or use of weapons and drugs and to intercultural conflicts.     

Volcanic Risk Exposure,Feelings of Insecurity,Stress, and Coping Strategies in México1

The present study investigates stress levels, feelings of insecurity, and coping strategies used by people living near an active volcano in México (Popocatépetl). The sample was composed of 198 adults, who were divided into 4 groups according to the risk zones in which they live. They answered a questionnaire addressing feelings of insecurity regarding volcanic risk, a coping strategies scale, and a stress scale. A significant interaction between active and passive coping strategies and risk zone was found. Higher levels of insecurity feelings regarding volcanic risk were associated with the highest stress levels evoked by facing a volcanic risk. A possible application of this study is at the community‐service level concerning risk prevention.     

Sociometric typologies during adolescence: contrasting different scoring techniques and formulas

Our aim in this work is to compare the different sociometric classification formulae and to analyze possible connections between each type of formula and each behaviour assessed by peers during adolescence. We classified a total of 1,009 Spanish fourth-grade secondary education students (15-year-olds) using four different systems: two were based on a nomination technique by Coie and Dodge, Newcomb and Bukowski, the third system was a modified version of the latter based on the revision of the neglected status, and a fourth system was based on the qualification scale by Maassen and Laandsheer. Results show a significant relation between all four classifications, but there are also differences among them. The classifications proceeding from the nomination technique share more similarities and also offer a better behavioural characterization of sociometric categories.     

Face familiarity, distinctiveness, and categorical perception

Four experiments with faces support the original interpretation of categorical perception (CP) as only present for familiar categories. Unlike in the results of Levin and Beale (2000), no evidence is found for face identity CP with unfamiliar faces. Novel face identities were shown to be capable of encoding for immediate sorting purposes but the representations utilized do not have the format of perceptual categories. One possibility explored was that a choice of a distinctive face as an end-point in a morphed continuum can spuriously produce effects that resemble CP. Such morphed continua provided unequal psychological responses to equal physical steps though much more so in a better likeness paradigm than for forced-choice recognition. Thus, researchers doing almost the same experiments may produce very different results and come to radically different conclusions.     

Introduction to the Special Section: Advances in psychological prevention and treatment interventions to promote children's mental health

This paper introduces the Special Section on Advances in Psychological Prevention and Treatment Interventions to Promote Children's Mental Health. The three articles in the Special Section provide perspectives on the adaptation, evaluation, and implementation of evidence‐based psychological interventions for children in countries in Northern and Eastern Europe, and Latin America. The articles highlight disparate methodologies for the examination of intervention data, including addressing causal inference in the absence of availability of true experiment data (i.e., randomised controlled trial data), randomised trial data from a school‐based prevention programme, and predictors of change in an evidence‐based treatment programme. Together, the articles highlight the movement of evidence‐based practices into routine care settings and emerging strategies for settings in which randomised trial data are not yet available. They demonstrate the contribution of psychological research to the advancement of practices for improving children's mental health.     

Vocabulary,Grammar, Sex,and Aging

Understanding the changes in our language abilities along the lifespan is a crucial step for understanding the aging process both in normal and in abnormal circumstances. Besides controlled experimental tasks, it is equally crucial to investigate language in unconstrained conversation. I present an information‐theoretical analysis of a corpus of dyadic conversations investigating how the richness of the vocabulary, the word‐internal structure (inflectional morphology), and the syntax of the utterances evolves as a function of the speaker's age and sex. Although vocabulary diversity increases throughout the lifetime, grammatical diversities follow a different pattern, which also differs between women and men. Women use increasingly diverse syntactic structures at least up to their late fifties, and they do not deteriorate in terms of fluency through their lifespan. However, from age 45 onward, men exhibit a decrease in the diversity of the syntactic structures they use, coupled with an increased number of speech disfluencies.     

Frequency of Interpersonal Trauma Types,Avoidant Attachment,Self-Compassion,and Interpersonal Competence: A Model of Persisting Posttraumatic Symptoms

Given limited knowledge about how psychosocial factors interact to modulate posttraumatic stress symptoms, this study evaluated an integrative model proposing that experiencing more interpersonal trauma types (e.g., abuse, assault, rape, etc.) leads to greater avoidant attachment and lower self-compassion, which limits the development and use of effective interpersonal skills. In turn, lower levels of self-compassion and interpersonal competence perpetuate posttraumatic symptoms. Anonymous trauma-experienced adults (n = 132) completed self-report measures in an online study hyperlinked on trauma support websites. Data were subjected to confirmatory factor analysis and structural equation modeling, which provided support for the hypothesized model. Specifically, higher frequency of interpersonal trauma types experienced was linked to higher avoidant attachment and lower self-compassion, which in turn were associated with lower interpersonal competence, which correlated with greater posttraumatic stress symptoms. Although cross-sectional data cannot address directionality of associations, this study’s findings emphasize the potential utility of future longitudinal research designed to examine possible causal relationships among these specific psychosocial factors. For example, study findings suggest that those who experience more types of interpersonal trauma and who are characterized by avoidant attachment and lower self-compassion and interpersonal competence may be the most susceptible to experiencing severe posttraumatic symptoms. However, findings also suggest that efforts to increase self-compassion and interpersonal skills may help reduce symptoms.
