Passion and Gambling: Investigating the Divergent Affective and Cognitive Consequences of Gambling1

Vallerand et al. (2003) developed a theoretical framework of passion where two types of passions are proposed: obsessive and harmonious passion. Obsessive passion is characterized by an internal pressure that pushes the person to engage in the passionate activity, whereas harmonious passion is characterized by the person's choice to engage in the activity. The goal of the present study was to examine the outcomes of these types of passion toward gambling. A total of 554 participants completed instruments assessing their passion toward gambling, as well as several cognitive and affective outcomes. Results indicated that, in general, harmonious passion was associated with positive outcomes, while obsessive passion was related to negative consequences. Results also showed that casino activities accentuated both positive and negative outcomes by fostering both types of passion toward the gambling activity. Conceptual and practical implications are discussed.     

Ideological beliefs as determinants of discrimination in positive and negative outcome distributions

Social identity theory proposes that discrimination contributes favourably to group members' social identity. In minimal group paradigm (MGP) studies involving positive outcome distributions (e.g. money), discrimination is associated with a more positive social identity. But studies on the positive‐negative asymmetry effect show that categorization leads to less discrimination when negative (salary cuts) than when positive outcomes (salary increases) are distributed. Using structural equation modelling, this study (N = 279) tested whether discrimination involving negative outcome distributions could contribute as much to group members' positive social identity as discrimination on positive outcomes. The study also tested if ideological beliefs (i.e. social dominance orientation, authoritarianism), measured one month before the MGP experiment, could predict positive and negative outcome discrimination. While the fit of the hypothesized model was adequate, only social dominance orientation predicted both positive and negative outcome discrimination. Also, discrimination on positive outcomes but not on negative ones contributed to positive social identity. Copyright © 2004 John Wiley & Sons, Ltd.     

The effect of reinforcement variables on inhibition in children with ADHD.

Behavioral inhibition, often cited as a central deficit in children with ADHD, has been shown to change in response to reinforcement. In this preliminary investigation, children with ADHD (n= 20) and matched controls (ages 7 to 12) completed a new version of the stop signal paradigm, the Fire Fighter Game, a measure of inhibition of a prepotent motor response, under three conditions: (1) no reinforcement; (2) immediate reinforcement; and (3) delayed reinforcement. In all conditions, the stop signal reaction time (SSRT) of children with ADHD was consistently longer than controls. Both groups improved significantly with reinforcement, and there was no strong evidence that immediate reinforcement was more effective than delayed reinforcement. However, it appeared that the reason for the changes in SSRT in response to reinforcement differed between the groups. Children in the control group responded faster on go trials, whereas children with ADHD improved their ability to inhibit responding with shorter stop delays. The relevance of these findings is discussed in terms of current theories of ADHD.     

Inadvertent plagiarism in everyday life

Inadvertent plagiarism is a source monitoring error described in laboratory studies. In the present study, the existence of this phenomenon in everyday life and the impact of a variable considered in laboratory (i.e. source similarity) were investigated. Two hundred and two participants were asked to remember an episode involving inadvertent plagiarism in the past, and to describe it. Results showed that inadvertent plagiarism occurs in real life conditions with respect to various types of activities. Moreover, source similarity had an impact on inadvertent plagiarism. In particular, same‐sex plagiarism occurred more often than opposite‐sex plagiarism. Copyright © 2005 John Wiley & Sons, Ltd.     

The visual perception of distance ratios outdoors

We conducted an experiment to evaluate the ability of 32 younger and older adults to visually perceive distances in an outdoor setting. On any given trial, the observers viewed 2 environmental distances and were required to estimate the distance ratio—the length of the (usually) larger distance relative to that of the shorter. The stimulus distance ratios ranged from 1.0 (the stimulus distances were identical) to 8.0 (1 distance interval was 8.0 times longer than the other). The stimulus distances were presented within a 26 m × 60 m portion of a grassy field. The observers were able to reliably estimate the stimulus distance ratios: The overall Pearson r correlation coefficient relating the judged and actual distance ratios was 0.762. Fifty-eight percent of the variance in the observers’ perceived distance ratios could thus be accounted for by variations in the actual stimulus ratios. About half of the observers significantly underestimated the distance ratios, while the judgments of the remainder were essentially accurate. Significant modulatory effects of sex and age occurred, such that the male observers’ judgments were the most precise, while those of the older males were the most accurate.     

Imaging the Impact of Prenatal Alcohol Exposure on the Structure of the Developing Human Brain

Prenatal alcohol exposure has numerous effects on the developing brain, including damage to selective brain structure. We review structural magnetic resonance imaging (MRI) studies of brain abnormalities in subjects prenatally exposed to alcohol. The most common findings include reduced brain volume and malformations of the corpus callosum. Advanced methods have been able to detect shape, thickness and displacement changes throughout multiple brain regions. The teratogenic effects of alcohol appear to be widespread, affecting almost the entire brain. The only region that appears to be relatively spared is the occipital lobe. More recent studies have linked cognition to the underlying brain structure in alcohol-exposed subjects, and several report patterns in the severity of brain damage as it relates to facial dysmorphology or to extent of alcohol exposure. Future studies exploring relationships between brain structure, cognitive measures, dysmorphology, age, and other variables will be valuable for further comprehending the vast effects of prenatal alcohol exposure and for evaluating possible interventions.     

A Review of Family Therapy as an Effective Intervention for Anorexia Nervosa in Adolescents

This review examines family therapy as an effective intervention for Anorexia Nervosa (AN) in adolescents. An electronic and manual literature search was conducted. Studies pertaining to family therapy in the treatment of AN and specifically, the Maudsley Method/Family-Based Treatment were identified. A limited number of randomized control trials exist implicating family therapy. Of the existent studies, methodological limitations pertaining to small, homogeneous sample sizes are evident. Despite the limited number of studies, family therapy appears to illustrate probable efficacy. Additional research and funding are necessary to fully support family therapy in the treatment of AN in adolescents.     

Bien-être à la retraite selon le genre et l’âge : lien avec la perception du travail ancien

We focused on the direct relationship between job satisfaction experienced during working life and life-satisfaction after retirement. Also we wonder on differences about aspects of the former work evoked as pleasant. These questions are treated by differentiating women and men perceptions, and the perceptions according to age. Data on 396 French subjects, 182 men and 214 women (age range 66 to 98) were used to examine how life-satisfaction in retirement is linked to the perception of former job satisfaction. Other indications of adaptation are retained, as self-esteem or conversely boredom. Results show a) that job satisfaction is a predictable variable for life-satisfaction after retirement, b) that this impact is weaker for youngest, c) a strong similarity between men and women, whatever is their age. We discuss observed links.
