Brief Report: Exposure to Muscular Male Models Decreases Men’s Body Satisfaction

The current study was designed to examine the effect of exposure to muscular ideal bodies on body satisfaction in men. College men (N= 104) at a medium-sized mid-south university completed the Body Assessment (BA)scale, which measures body satisfaction, before and after exposure to either muscular or nonmuscular advertisements. BA scores were examined using a repeated measures (pre and post) ANOVA with muscularity of image (view images of muscular men vs. view images ofaverage men) as the between-participants factor. Results indicated that men’s self-rated body satisfaction decreased after viewing images of muscular men but did not change after viewing images of average men. Thus, it appears that men’s body satisfaction may be influenced by exposure to brief images of muscular models. These results are congruent with results of previous investigations of the effects of viewing images of thin models on women’s body satisfaction.     

Role of Surface Roughness in Hysteresis during Adhesive Elastic Contact

In experiments that involve contact with adhesion between two surfaces, as found in atomic force microscopy or nanoindentation, two distinct contact force (P) vs. indentation-depth (h) curves are often measured depending on whether the indenter moves towards or away from the sample. The origin of this hysteresis is not well understood and is often attributed to moisture, plasticity or viscoelasticity. Here we report experiments that show that hysteresis can exist in the absence of these effects, and that its magnitude depends on surface roughness. We develop a theoretical model in which the hysteresis appears as the result of a series of surface instabilities, in which the contact area grows or recedes by a finite amount. The model can be used to estimate material properties from contact experiments even when the measured P-h curves are not unique.     

Keeping the vermin out: Perceived disease threat and ideological orientations as predictors of exclusionary immigration attitudes

Integrating evolutionary and social representations theories, the current study examines the relationship between perceived disease threat and exclusionary immigration attitudes in the context of a potential avian influenza pandemic. This large‐scale disease provides a realistic context for investigating the link between disease threat and immigration attitudes. The main aim of this cross‐sectional study (N = 412) was to explore mechanisms through which perceived chronic and contextual disease threats operate on immigration attitudes. Structural equation models show that the relationship between chronic disease threat (germ aversion) and exclusionary immigration attitudes (assimilationist immigration criteria, health‐based immigration criteria and desire to reduce the proportion of foreigners) was mediated by ideological and normative beliefs (social dominance orientation, belief in a dangerous world), but not by contextual disease threat (appraisal of avian influenza pandemic threat). Contextual disease threat only predicted support for health‐based immigration criteria. The conditions under which real‐life disease threats influence intergroup attitudes are scrutinized. Convergence and dissimilarity of evolutionary and social representational approaches in accounting for the link between disease threat and immigration attitudes are discussed.

Are Psychiatric Residents Still Interested in Psychoanalysis? A Brief Report

In spite of the efficacy of the psychodynamic psychotherapies, the number of young psychiatric residents interested in psychodynamic therapies is decreasing. Our psychoanalytical group, Genden (Genève-Denver), explored the possible reasons for psychiatric residents' hesitation to get psychoanalytic training. Five psychoanalytical psychotherapists met weekly for a year in order to debate that question, focusing on personal feedbacks from all of our 100 residents in psychiatry working with us for at least 4 years. Following the residents' responses, our focus group proposed ten commonsense feedbacks for psychoanalysts regarding stimulating young psychiatric residents' interest in psychoanalytic approaches.     

Developmental pathways in oppositional defiant disorder and conduct disorder

The Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV; American Psychiatric Association, 1994) specifies a developmental relationship between oppositional defiant disorder (ODD) and conduct disorder (CD). Evidence for this link is mixed, however, and recent studies suggest that different symptom dimensions in ODD may have different outcomes. The authors examined links between ODD, CD, and their young adult outcomes in the Great Smoky Mountains Study (E. J. Costello et al., 1996), a longitudinal data set with over 8,000 observations of 1,420 individuals (56% male) covering ages 9-21 years. ODD was a significant predictor of later CD in boys but not in girls after control for comorbid CD and subthreshold CD symptomatology. Transitions between ODD and CD were less common than anticipated, however, particularly during adolescence. The authors examined characteristics and outcomes of children with pure ODD, pure CD, and combined CD/ODD. Alongside many similarities in childhood and adolescent correlates, key differences were also identified: CD largely predicted behavioral outcomes, whereas ODD showed stronger prediction to emotional disorders in early adult life. Factor analysis identified irritable and headstrong dimensions in ODD symptoms that showed differential prediction to later behavioral and emotional disorders. Overall, the results underscore the utility of retaining separate ODD and CD diagnoses in DSM-V.     

A neurodevelopmental perspective on male violence

Research is increasingly documenting a neurobiological basis to violence. This review takes a neurodevelopmental perspective on the very small group of males who grow up to become persistent violent offenders. After outlining six criteria for what constitutes a neurodevelopmental disorder, the extent to which chronic violence meets these definitional criteria is examined, covering the fields of genetics, structural and functional brain imaging, and neuropsychology. Early health risk factors for violence are then outlined, including birth complications, minor physical anomalies, prenatal smoking and alcohol exposure, poor nutrition, lead exposure, and traumatic brain injury. Persistent adult violence is argued to originate in aberrant temperamental behavior in early childhood, to have a stable developmental trajectory, and to be associated with impaired education, social, and occupational functioning. Taken together, it is argued that chronic adult violence meets criterion for being conceptualized as having neurodevelopmental origins and that an important, but not sole, source of neural maldevelopment lies in prenatal and early postnatal risk factors. This review concludes with a recognition of the sociopolitical context within which a neurodevelopmental perspective on chronic violence sits, together with directions for future research, including whether a neurodevelopmental hypothesis is best applied to reactive as opposed to proactive aggression.     

Attributional style and self-esteem as predictors of psychological well being

Background: this study sets out to examine to what extent attributional style (internal, stable, global) and self-esteem predicted positive affect and self-reported happiness in a normal, non-clinical, population of young people in their early 20s. Method: 88 participants completed five questionnaires: Attributional Style Questionnaire (ASQ in both positive and negative situations), Bradburn Affect Scales (Positive Affect, Negative Affect, and Affect Balance Scale), Rosenberg Self-Esteem Scale Gurin Happiness Measure, and Oxford Happiness Inventory (OHI). Results: regressional analysis showed that the ASQ was the significant predictor of happiness accounting for 18% of variance. The ASQ in positive and negative situations was significantly inversely correlated with self-esteem. Further, with happiness (the OHI) as dependent variable and attributional style, self-esteem, and demographic variables as independent variables, self-esteem and attributional style (in positive situations) were the significant predictors of happiness accounting for 55% of the total variance. Conclusion: the results indicated that optimistic attributional style in positive situations was a stronger predictor of self-reported happiness than optimistic attributional style in negative situations. The implications of the findings are discussed in terms of cognitive strategies for changing pessimism into optimism thus enhancing happiness or psychological well-being.
