The relation between risk perceptions and physical activity among older adults: A prospective study

Past studies have found that risk perceptions of suffering from diseases play an important role in the development of intentions to perform physical activity (PA). According to the behaviour motivation hypothesis, perceived risk could be positively and directly related to PA, but this possibility has been ignored and/or underestimated. Accounting for recent methodological developments on the importance of study design and risk perception assessment, the purpose of the present study was to examine the risk-perceptions–PA relationship among older adults. Participants (N?=?143) aged from 61 to 70 years initially underwent measurement of risk perceptions, baseline PA, socio-demographic and health factors. Six months later, they were asked about their PA participation. Multiple regression analyses revealed that perceived risk of suffering from diseases and conditions without regular PA participation was an independent positive predictor of later PA, over and beyond baseline behaviour, socio-demographic and health variables. This study fills a gap in the existing literature on the PAs of older adults and reveals that risk perceptions are directly linked to their participation. In addition, it extends existing knowledge in health psychology on the behaviour motivation hypothesis, and emphasises the necessity of methodological adjustments when assessing the risk-perception–behaviour relationship.     

Continuities and Changes in the Friendships of Children with and Without ADHD: A Longitudinal, Observational Study

We examined how the real-life dyadic friendships of 87 children with ADHD and 46 comparison children (76 % boys) aged 7–13 years evolved during a 6-month follow-up period. The methods included friendship quality self-report measures and direct observation of friends’ dyadic behaviors in three structured analogue tasks. At Time 2, the friends of the participants with ADHD reported less positive friendship quality and more conflict with their friends than at Time 1. They were also considerably less satisfied with their friendship than 6 months prior. In contrast, the friends of comparison children reported fewer negative friendship features, more positive friendship features and a slightly greater friendship satisfaction than at Time 1. In sharp contrast with the invited friends’ reports, referred children with ADHD did not report deterioration in their friendship quality over time. Unlike comparison children who significantly reduced violations of game rules between Time 1 and Time 2, children with ADHD broke more game rules during the same period. In negotiating with friends, comparison children, but not children with ADHD, reduced the number of self-centered and insensitive proposals at Time 2. Controlling for Time 1 variance, violations of game rules and a self-centered, insensitive negotiation approach predicted deterioration in friendship quality for children with and without ADHD over time.     

Life History theory and social deviance: The mediating role of Executive Function

The present work examined predicted relations among Life History strategies, Executive Functions, socially antagonistic attitudes, socially antagonistic behaviors, and general intelligence. Life History (LH) theory predicts that Executive Functions and socially antagonistic attitudes and behaviors underpin an interrelated and coherent set of behavioral strategies (LH strategies) designed to enhance reproductive success. Specifically, LH theory predicts a positive relation between Executive Functioning and LH strategies; a negative relation between socially antagonistic attitudes and behaviors and LH strategies; and that Executive Functions mediate relations among LH strategies and socially antagonistic attitudes and behaviors. Results from a Structural Equation Model (SEM), based on self-reported Life History strategies, Executive Functioning, socially antagonistic attitudes and behaviors, and general intelligence support these predictions. The structure of the model suggests that Executive Functions serve a mediating role in the relations between LH strategy and social deviance.     

An Accumulation of Negative Life Events and the Construction of Alexithymia: A Longitudinal and Clinical Approach

We began the study with a theoretical comparison of the concepts of alexithymia and operative thought in terms of etiology as well as with a specific approach to comparing the concepts using the Rorschach Inkblot Method (Rorschach, 1921 Rorschach, H. 1921. Psychodiagnostic, Paris, , France: Presses Universitaires de France.  [Google Scholar]) with both Exner's (1986) Comprehensive System and the Parisian School (Chabert, 1983 Chabert, C. 1983. Le Rorschach en clinique adulte: Interprétation psychanalytique [The Rorschach in adult clinical settings: Psychoanalytic interpretation], Paris, , France: Dunod.  [Google Scholar], 1987 Chabert, C. 1987. La Psychopathologie à travers le Rorschach [Psychopathology throughout the Rorschach], Paris, , France: Dunod.  [Google Scholar]; Rausch de Traubenburg, 2000) methods of coding and interpretation. We then present a longitudinal clinical study of a woman suffering perinatal depression starting at 8 months gestation until 34 months postpartum. The case shows how an accumulation of stressful and traumatic life events in the early perinatal period generates a reactive, structured alexithymia. This psychic process transforms an initial acceptance of therapy into a refusal to engage in a therapeutic alliance along with persistent depressive symptoms, impaired quality of life, and maladaptive coping strategies.     

Death, Cadavers and Post-mortem Biomedical Research: A Point of View from a Christian Community

Facing modern developments of medicine and biomedical researches, religious communities are a strong source of ethics principles and orientations. Human dignity does not disappear after life, in a context of biomedical research on cadavers. Moral, political, social and scientific aspects of research on human cadavers (mainly autopsies) have been widely discussed in biomedical publications, whereas the religious ones (which could be predominant for some) have rarely been analyzed and presented. This article will present the results of a survey carried out a French Benedictine Abbey (relative to death, cadaver’s status and biomedical research) and subsequent Christian background according to canonic texts and practical cases from anthropological, historical, archeological and biomedical origin.     

Interference resolution moderates the impact of rumination and reappraisal on affective experiences in daily life

Research has shown that cognitive control processes play a central role in emotion regulation. While most research has examined whether individual differences in such processes are related to the use of these strategies, a crucial next step involves examining whether such differences influence their impact on people's feelings, especially in normal daily life. The present study examined whether impairments in cognitive control (measured using an affective interference resolution task) moderate the impact of using rumination and reappraisal on affective experiences in everyday life (assessed using experience sampling methods). Multilevel analyses revealed that difficulties removing previously relevant negative information from working memory were associated with a larger increase in negative affect following rumination, and smaller increase and decrease in positive and negative affect, respectively, following reappraisal. These findings show that impaired interference resolution for negative information aggravates the deleterious effects of rumination and curbs the benefits of reappraisal in daily life.     

A Longitudinal Study of Perceived Conflict and Instrumental Relationships Between Life Contexts Among Adolescents: The Role of Self-Determined Motivation

This study is a 3-year follow-up of 746 adolescents on the evolution of perceived conflicting or instrumental relationships between sport, education, and friendship. School-to-sport conflict increases with age, in particular among boys, and is maximal among adolescents self-determined toward sport but not toward school. Sport-to-school instrumentality increases among boys, decreases among girls, and is positively linked to contextual self-determined motivation. Friendship-to-sport conflict is more prevalent at the beginning and the end of adolescence, among girls, and is negatively linked to friendship self-determined motivation. Sport-to-friendship instrumentality decreases during adolescence, in particular for females, and is positively associated with contextual self-determined motivation.     

Metadehumanization and Self-dehumanization are Linked to Reduced Drinking Refusal Self-Efficacy and Increased Anxiety and Depression Symptoms in Patients with Severe Alcohol Use Disorder

Metadehumanization, the perception of being treated as less than a human by others, is a pervasive phenomenon in intergroup relations. It is dissociated from stigmatization or stereotypes, and it has been recently identified as a critical process in severe alcohol use disorders (SAUD). Metadehumanization is associated with a wide array of negative consequences for the victim, including negative emotions, aversive self-awareness, cognitive deconstruction, and psychosomatic strains, which are related to anxiety and depression. This study aims to investigate if metadehumanization occurring among patients with SAUD is associated with clinical factors involved in the maintenance of the disease, namely symptoms of depression or anxiety and drinking refusal self-efficacy. A cross-sectional study was conducted among 120 patients with SAUD. Self-reported questionnaires measured metadehumanization, self-dehumanization (i.e., the feeling of being less than a human), anxiety, depression, drinking refusal self-efficacy, and demographics. Metadehumanization was significantly associated with self-dehumanization, anxiety, depression, and drinking refusal self-efficacy. Additionally, path analyses showed that self-dehumanization mediated the links between metadehumanization and clinical variables. These results indicate that metadehumanization and self-dehumanization could be essential factors to consider during SAUD treatment, as they are associated with increased psychiatric symptoms and reduced drinking refusal self-efficacy.     

Young Children's Knowledge of the Representational Function of Pictorial Symbols: Development Across the Preschool Years in Three Cultures

Three- to 5-year-old children's knowledge that pictures have a representational function for others was investigated using a pictorial false-belief task. In Study 1, children passed the task at around 4 years old, and performance was correlated with standard false-belief and pictorial symbol tasks. In Study 2, the performance of children from two cultural settings who had very little exposure to pictures during the first 3 years (Peru, India) was contrasted with that of children from Canada. Performance was better in the Canadian than Peruvian and Indian samples on the picture false-belief task and drawing tasks but not on the standard false-belief measure. In all settings, children passed drawing and standard false-belief tasks either concurrently with, or prior to, passing the picture false-belief task. The findings suggest that children's explicit knowledge of the representational function of pictorial symbols matures in the late preschool years and develops more rapidly in cultures that strongly promote the symbolic use of pictures early in life.     

The cognitive and neural basis of option generation and subsequent choice

Decision-making research has thoroughly investigated how people choose from a set of externally provided options. However, in ill-structured real-world environments, possible options for action are not defined by the situation but have to be generated by the agent. Here, we apply behavioral analysis (Study 1) and functional magnetic resonance imaging (Study 2) to investigate option generation and subsequent choice. For this purpose, we employ a new experimental task that requires participants to generate options for simple real-world scenarios and to subsequently decide among the generated options. Correlational analysis with a cognitive test battery suggests that retrieval of options from long-term memory is a relevant process during option generation. The results of the fMRI study demonstrate that option generation in simple real-world scenarios recruits the anterior prefrontal cortex. Furthermore, we show that choice behavior and its neural correlates differ between self-generated and externally provided options. Specifically, choice between self-generated options is associated with stronger recruitment of the dorsal anterior cingulate cortex. This impact of option generation on subsequent choice underlines the need for an expanded model of decision making to accommodate choice between self-generated options.
