Les déterminants psychologiques de la blessure physique du sportif : une revue de littérature

The purpose of the present paper is to review the studies having focused on the psychological antecedents of physical injury in a sport context. As a whole, the researches conducted in this field have highlighted the influence of stress in injuries-related problems. However, other researches in health psychology propose that complementary factors and processes could lead to be injured. Beyond the stress influence, these models suggest that the voluntary adoption of health or risky behaviours could play a role in the occurrence of sport-related injuries. The psychological determinants of these behaviours are now identified. Few studies however sought to show the relevance of these determinants in the identification of the athletes likely to be injured. A model is suggested in order to engage research in this field.     

On the social nature of global self-esteem: a replication study

Few researchers have considered the relationship between global self-esteem and the reflected appraisal of others in one's life, or how reflected appraisals and global self-esteem may change as a result of interpersonal feedback. In this study, the authors collected data from 110 undergraduate students on (a) their global self-esteem and the reflected appraisals of multiple others in their lives and (b) how these dimensions changed in hypothetical interpersonal-feedback situations. Results showed that participants' global self-esteem was related to the reflected appraisals of their fathers, teachers, and friends. The results also indicated that others' reflected appraisals and the individual's global self-esteem fluctuated according to the nature (i.e., positive vs. negative) of the hypothetical interpersonal feedback. Overall, the findings emphasize the social nature and regulation of global self-esteem.     

The neural regions sustaining episodic encoding and recognition of objects

In this functional MRI experiment, encoding of objects was associated with activation in left ventrolateral prefrontal/insular and right dorsolateral prefrontal and fusiform regions as well as in the left putamen. By contrast, correct recognition of previously learned objects (R judgments) produced activation in left superior frontal, bilateral inferior frontal, and right cerebellar regions, whereas correct rejection of distractor objects (N judgments) was associated with activation in bilateral prefrontal and anterior cingulate cortices, in right parietal and cerebellar regions, in the left putamen, and in the right caudate nucleus. The R minus N comparison showed activation in the left lateral prefrontal cortex and in bilateral cingulate cortices and precunei, while the N minus R comparison did not reveal any positive signal change. These results support the view that similar regions of the frontal lobe are involved in episodic encoding and retrieval processes, and that the successful episodic retrieval of newly learned objects is mainly based on a frontoparietal network.     

Neural correlates of emotion regulation in psychopathology

What can psychopathology and its treatment tell us about cognitive emotional interactions? Standard approaches to interactions between emotion and cognition often adopt a variant of the idea that cognitive processes, subserved by dorsal and lateral cortical circuits, exert control and regulation of ventral, limbic brain areas associated with emotional expression and experience. However, it is becoming clear from studies on depression, post-traumatic stress disorder (PTSD) and obsessive compulsive disorder (OCD), that a binary, opponent theory of cognitive emotion interaction (CEI) and the dorsal-ventral model of neurocircuitry do not fully describe the data. We summarize recent research to suggest that networks of direct and indirect pathways exist by which cognition can regulate pathological emotion, and the inter-relationships of specific nodes within the networks need to be characterized.     

The Effects of Perceived Dysfunctional Family-of-Origin Rules on the Dating Relationships of Young Adults

This study examined the effects of perceived dysfunctional family-of-origin rules on the dating relationships of young adult offspring. A sample of 322 students from three universities completed self-report questionnaires measuring dysfunctional family-of-origin rules, current dating behaviors, dating anxiety, relationship satisfaction and commitment. The results indicated that dysfunctional family-of-origin rules were positively related to dating anxiety, and negatively related to advancement in dating stages, relationship satisfaction, and commitment in the dating relationships of young adults. There also was a tendency for young adults from families with dysfunctional rules to date later and less frequently than young adults from families with more functional rules, although they dated about the same number of partners. Implications for future research and clinical interventions are discussed.     

Risk Factors of Sexual Aggression and Victimization Among Homosexual Men1

This study examined risk factors of sexual aggression and victimization among homosexual men (N= 310). They completed the Homosexual Experiences Survey to record sexual aggression and victimization and provided information about 2 groups of potential risk factors: childhood abuse and sexual lifestyle (number of partners, age at first intercourse, age at coming out, accepting or paying of money for sex, and rape proclivity). One in 4 respondents reported severe forms of sexual victimization; 17% reported moderate victimization. Prevalence of perpetration of sexual aggression was almost 20% for severe aggression and 9% for moderate aggression. The risk of victimization increased as a function of childhood abuse as well as high number of partners and acceptance of money for sex. The risk of committing sexual aggression was positively related to childhood abuse, acceptance and payment of money for sex, high number of sexual partners, and rape proclivity. The findings are discussed in relation to evidence on heterosexual aggression.     

Kann man die akute Gefährlichkeit schizophren Erkrankter erkennen?

Homicidal acts of schizophrenic persons get a lot of public attention and fuel fears about the dangerousness of the mentally ill. There is indeed a small subgroup of psychotics who are involved in violent acts in disproportionate amounts, especially in the case of co-morbid substance abuse. As most of these offenders were in psychiatric treatment beforehand, it has to be questioned whether their dangerousness could have been recognized and whether adequate intervention would have been possible. This paper describes the factors which can lead to a long-term increase in the risk of violent behaviour in schizophrenia, and also criteria which indicate acute dangerousness.
