Does Self-Enhancement Facilitate Task Performance?

Self-enhancement is a pervasive motivation that manifests broadly to promote and protect the positivity of the self. Research suggests that self-enhancement is associated with improved task performance. Untested, however, is whether that association is causal. The present research experimentally manipulated self-enhancement to examine its causal effect on task performance. Participants in 5 experiments were randomly assigned to self-enhance or not before completing a creativity task (Experiments 1–4) or pain-inducing cold-pressor task (Experiment 5). Results indicate that self-enhancing (but not self-effacing) on a dimension relevant (but not irrelevant) to the task facilitated performance. Furthermore, the data were consistent with the possibility that the performance facilitating effect of self-enhancement was mediated through task-relevant self-efficacy

To Which World Regions Does the Valence-Dominance Model of Social Perception Apply?

Over the last ten years, Oosterhof and Todorov’s valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgments of faces. To which world regions this model applies is a critical, yet unanswered, question. We will address this question by replicating Oosterhof and Todorov’s methodology across multiple world regions

When Rejection by One Fosters Aggression Against Many: Multiple-Victim Aggression as a Consequence of Social Rejection and Perceived Groupness

Two experiments examined the hypothesis that social rejection and perceived groupness function together to produce multiple-victim incidents of aggression. When a rejecter’s group membership is salient during an act of rejection, the rejectee ostensibly associates the rejecter’s group with rejection and retaliates against the group. Both experiments manipulated whether an aggregate of three persons appeared as separate individuals or members of an entity-like group and whether one of those persons rejected the participant. Consistent with the hypothesis, participants who experienced both rejection and perceived groupness behaved more aggressively against the aggregate (Experiment 1) and evidenced less favorable affective associations toward the aggregate (Experiment 2) than did participants who did not experience both rejection and perceived groupness

Effects of Supplementary Concentrate Level and Separate or Mixed Feeding of Grass Silage and Concentrates on Rumen Fluid Composition in Steers

The effects of dietary concentrate level and method of feeding (separate or mixed) on performance and carcass traits of steers may be mediated through changes in rumen fluid composition. The objectives of this study were to determine the effects on rumen fluid composition of (1) supplementary concentrate level with grass silage, and (2) separate or mixed feeding of silage and concentrates

Effects of Supplementary Concentrate Level and Separate or Mixed Feeding of Grass Silage and Concentrates on Carcass Tissue Composition in Steers

Supplementary concentrate level may affect carcass composition in steers. Feeder wagons facilitate feeding and management. The objectives were to determine the effects of (1) supplementary concentrate level with grass silage, and (2) separate or mixed feeding of silage and concentrates, on ribs joint composition

The Impact of Concentrate Price on the Utilization of Grazed and Conserved Grass

A linear programming model was designed and constructed to facilitate the identification of optimal beef production systems under varying technical and policy scenarios. The model operates at a systems level and most activities that could occur in Irish spring-calving, suckler beef production systems are included. In this paper, the components of the model are described together with a simple application of the model involving changing concentrate prices

Examining DBT Day Treatment in Treating Mood Dysregulation Expectancy and Anxiety in Women Diagnosed with Eating Disorders

Eating disorders (EDs), particularly anorexia nervosa (AN) and bulimia nervosa (BN), are characterized by emotional and behavioral disturbances in eating patterns and body image that result in significant distress and functional impairment (as reported by APA, (APA dictionary of psychology, American Psychological Association, Washington, DC, 2015)). Ben-Porath and colleagues (Journal of Contemporary Psychotherapy 40:115-123, 2010) have researched the effectiveness of dialectical behavioral therapy (DBT) day treatment program in reducing negative mood regulation and anxiety among women diagnosed with AN, BN, and eating disorder not otherwise specified (EDNOS). The current study extended past research on the effectiveness of DBT day treatment by analyzing the improvement in these patients’ scores on the beck anxiety inventory (BAI) and the generalized expectancy for negative mood regulation (NMR) Scale after treatment. We compared pre- and post-treatment scores using paired samples t-tests. We also examined rates of clinically significant change in these areas post-treatment. The results indicated that participants demonstrated a reduction in expectancies for negative mood dysregulation and anxiety after undergoing DBT day treatment for EDs. Limitations and implications of this study are discussed

Positively Biased Appraisals in Everyday Life: When Do They Benefit Mental Health and When Do They Harm It?

To promote optimal mental health, is it best to evaluate negative experiences accurately or in a positively biased manner? In an attempt to reconcile inconsistent prior research addressing this question, we predicted that the tendency to form positively biased appraisals of negative experiences may reduce the motive to address those experiences and thereby lead to poorer mental health in the context of negative experiences that are controllable and severe but lead to better mental health in the context of controllable negative experiences that are less severe by promoting positive feelings without invoking serious consequences from unaddressed problems. In 2 longitudinal studies, individuals in new marriages were interviewed separately about their ongoing stressful experiences, and their own appraisals of those experiences were compared with those of the interviewers. Across studies, spouses\u27 tendencies to form positively biased appraisals of their stressful experiences predicted fewer depressive symptoms over the subsequent 4 years among individuals judged to be facing relatively mild experiences but more depressive symptoms among individuals judged to be facing relatively severe experiences. Furthermore, in Study 2, these effects were mediated by changes in those experiences, such that the interaction between the tendency to form positively biased appraisals of stressful experiences and the objectively rated severity of initial levels of those experiences directly predicted changes in those experiences, which in turn accounted for changes in depressive symptoms. These findings suggest that cognitive biases are not inherently positive or negative; their implications for mental health depend on the context in which they occur

The Effects of a High Grass Input Feeding System Compared to High Concentrate Input Feeding System Offered to Spring Calving Dairy Cows in Early Lactation

Grazed grass is the cheapest feed available on Irish dairy farms. The inclusion of grass in the diet of the spring-calving dairy cow in early lactation is recommended. Previous studies focused on introducing grazed herbage into the cows diet in early spring in conjunction with grass silage and concentrate, and compared this to cows fed indoors. The objective of this study was to compare the milk production and feed budget of two contrasting early lactation feeding regimes. One regime was based on a high herbage inclusion with a low concentrate level (HG), while the other was based on a high concentrate inclusion with grass silage (HC)

Effects of Supplementary Concentrate Level and Separate or Mixed Feeding of Grass Silage and Concentrates on Carcass Tissue Colour Traits in Steers

The level of supplementary concentrates fed with grass silage and the method of feeding (separate or mixed) may affect carcass tissue colour in steers. The objectives were to determine the effects of (1) supplementary concentrate level with grass silage, and (2) separate or mixed feeding of silage and concentrates, on muscle and fat colour
