Relations of social problem solving with interpersonal competence in Japanese students

To clarify the relations of the dimensions of social problem solving with those of interpersonal competence in a sample of 234 Japanese college students, Japanese versions of the Social Problem-solving Inventory-Revised and the Social Skill Scale were administered. Pearson correlations between the two sets of variables were low, but higher within each set of subscales. Cronbach's alpha was low for four subscales assessing interpersonal competence.     

Chilean validation of the Posttraumatic Stress Disorder Checklist-Civilian version (PCL-C) after the earthquake on February 27, 2010

Posttraumatic stress disorder (PTSD) is an anxiety disorder in which an individual re-experiences a traumatic event, avoids situations related to it, and shows excessive arousal. The disorder appears after experiencing a life-threatening event, such as a war or a natural disaster. Thus, the validation of tests which assess the disorder after the earthquake on February 27, 2010, in Chile is crucial for its evaluation and subsequent intervention. The present study includes psychometric data for the Posttraumatic Stress Disorder Checklist-Civilian version (PCL-C) on a sample of 509 survivors of the disaster. Values indicate good psychometric properties of the questionnaire.     

Empathy, values, morality and Asperger's syndrome

The aims of this study were, first, to re-address the issue of empathy among people with autism conditions; second, to explore the relationships between empathy and values among autistic populations and controls; and third, to explore the capacity for moral agency among those affected by autism. We compared responses of an Asperger group (N = 41) and a control group (N = 139) to measures of self-reported empathy (Davis's IRI) and value priorities (Schwartz's PVQ). Control group results were largely in line with previous studies, such that empathy subscales of perspective taking and empathic concern showed their strongest positive and negative relations to the Schwartz self-transcendence/self-enhancement dimensions. Results for the Asperger group showed that although on the one hand there were self-reported difficulties in perspective taking and the cognitive recognition of affect, and that on the other hand there were less connections between the empathy and value measures, there was nevertheless a comparable prioritization of moral values. Conclusions suggest that different people may acquire moral values through different mechanisms.     

Matching- and nonmatching-to-sample concept learning in rats using olfactory stimuli

Previous research has shown that rats can learn matching-to-sample relations with olfactory stimuli; however, the specific characteristics of this relational control are unclear. In Experiment 1, 6 rats were trained to either match or nonmatch to sample in a modified operant chamber using common household spices as olfactory stimuli. After matching or nonmatching training with 10 exemplars, the contingencies were reversed with five new stimuli such that subjects trained on matching were shifted to nonmatching and vice versa. Following these reversed contingencies, the effects of the original training persisted for many trials with new exemplars. In Experiment 2, 9 rats were trained with matching procedures in an arena that provided for 18 different spatial locations for comparison stimuli. Five subjects were trained with differential reinforcement outcomes and 4 with only one type of reinforcer. Differential outcomes and multiple exemplars facilitated learning, and there was strong evidence for generalization to new stimuli for most rats that acquired several conditional discriminations. Performances with novel samples were generally above chance, but rarely reached the high levels obtained during baseline with well-trained stimulus relations. However, taken together, the data from the two experiments extend previous work, show that rats can learn both match and nonmatch relations with different experimental protocols, and demonstrate generalization to novel sample stimuli.     

Emotional Dynamics in the Development of Early Adolescent Psychopathology: A One-Year Longitudinal Study

This study examined the role of the level and variability of happiness, anger, anxiety, and sadness in the development of adolescent-reported anxiety disorder symptoms, depressive symptoms, and aggressive behavior in 452 adolescents (250 male) followed from age 13 to 14. Level and between-day variability of emotions were assessed through adolescent report at 3-month intervals across a 1 year period. Level and variability of the four emotions contributed to changes in anxiety disorder and depressive symptoms more consistently than to changes in aggressive behavior. All four emotions were predictive of changes in internalizing problems, while anger played the most prominent role in the development of aggressive behavior. Variability of emotions contributed to changes in anxiety disorder symptoms, while heightened levels of negative emotions and diminished happiness contributed to changes in depression. Results suggested somewhat stronger effects of negative affect on aggressive behavior for females than for males. Results underscore the role of emotion dysregulation in the development of psychopathology.     

Criminal thinking patterns, aggression styles, and the psychopathic traits of late high school bullies and bully-victims

This study explored the current psychological characteristics and criminal behavior history of individuals who retrospectively reported being bullies, bully-victims, victims, or controls (i.e. neither victims nor bullies) during their last 2 years of high school. College students (n = 960) completed measures of criminal thinking, aggression, psychopathy, and criminal behavior online. We predicted bullies and bully-victims would demonstrate the highest scores for criminal thinking, proactive aggression, psychopathy, and have the most criminal infractions. Bullies and bully-victims had significantly higher scores on criminal thinking, aggression, psychopathy, and criminal behaviors than victims or controls. Additionally, men were significantly higher in criminal thinking, aggression, psychopathy, and had more criminal acts than women. There were no gender by bully group interactions. Logistic regression analyses differentiated bully-victims from bullies. Bully-victims tended to be male, higher in criminal thinking, and higher in reactive aggression. In addition, bully-victims were distinct from victims, showing higher criminal thinking and higher proactive aggression.     

The development of the Social Bullying Involvement Scales

This study reports findings of a newly developed measure of social bullying based on Underwood's [2003] framework of social aggression. The Social Bullying Involvement Scales (SBIS) consist of four scales measuring the extent to which children experience social victimization, engage in social bullying, witness social bullying, and intervene in social bullying. The sample consisted of 636 participants (311 females and 325 males, age range 11-16 years; 71% White). Confirmatory factor analysis supported a revised version of Underwood's framework for each of the four participant role scales. Internal consistencies for each scale ranged from .93 to .97. Results revealed that social victimization was related to an increase in anxiety, depressive, and externalizing behaviors. Social bullying was associated with an increase in general externalizing behaviors only. Social witnessing was moderately correlated with depression scores. Intervening in social bullying was not linked with psychological maladjustment or externalizing behaviors. The SBIS provides a comprehensive measure of social victimization, social bullying, social witnessing, and social intervening.     

Gender symmetry in intimate aggression: an effect of intimacy or target sex?

Men's greater use of direct aggression is not evident in studies of intimate partner aggression. In previous research, the effects of target sex and relationship intimacy have frequently been confounded. This study sought to examine these effects separately. One hundred and seventy-four participants (59 male and 115 female) read vignette scenarios in which they were provoked by a same-sex best friend, an opposite-sex best friend, and a partner. For each target, participants estimated their likely use of direct physical and verbal aggression as well as noninjurious forms of anger expression. Results showed that men lower their aggression in the context of an intimate partnership and that this is an effect of the target's sex. In contrast, women raise their aggression in the context of an intimate partnership and this is an effect of intimacy with the target. The use of noninjurious angry behavior did not vary between targets for either sex of the participant, which suggests that the effects of target are confined to behaviors which carry an intention to harm. Possible effects of social norms and oxytocin-mediated emotional disinhibition on intimate partner aggression are discussed.
