Abstract

Elite athletes are characterized by their high level of performance in sport. Since the very beginnings of sport, it has been understood that physical and physiological abilities influence the performance of athletes. Advances in scientific knowledge, especially sport psychology and neuroscience, seem to confirm this intuition and consequently it is possible to characterize elite athletes as having an extraordinary combination of physical and mental abilities. Techniques and substances that contribute to enhancing physical characteristics of athletes have also been well known for ages. But it is now possible to make use of other techniques and substances that not only enhance physical abilities but also cognitive capabilities, which seem to require greater consideration given their direct impact on the athlete’s brain. In this article, we examine two such techniques, cognitive enhancers and transcranial stimulators, and highlight the potential advantages and drawbacks that applying each one may have on sport. Given the relative novelty of these enhancement techniques and substances and the absence of conclusive evidence regarding their short- and long-term effects, we deem that their use ought to be strictly governed by cautionary principles. But due to that same lack of evidence, we believe that the possibility of examining the feasibility of applying these techniques to sport should not be denied.  相似文献

The goal of this study is to explore the relationship, suggested by recent developmental approaches, between several aspects of self-knowledge organization and depressive symptomatology in late adolescence, within the comprehensive framework of Kelly's personal construct psychology. The repertory grid technique was used to obtain six measures of self-knowledge organization: global differentiation; polarization; presence of conflicts; and discrepancies between actual self, ideal self, and others. Two inventories were used to create two samples of late adolescents according to their level of depressive symptoms. Results supported the expectations of greater global differentiation and actual–ideal self discrepancy (or lower self-esteem) for adolescents with depressive symptoms, as well as a higher likelihood of intrapersonal conflicts. However, discrepancies between self (actual or ideal) and others (identification, and perceived adequacy of others), and polarization showed no significant differences. Furthermore, the association of symptom severity with different grid measures was stronger for adolescents with depressive symptoms. Results and limitations of this study are discussed, and the potential of using personal construct theory and the repertory grid technique in studies of self-knowledge and psychological adjustment during adolescence is explored.  相似文献

Background/ObjectiveTo test the effectiveness of an 8-week before-school physical activity program to reduce bullying victimization among a group of socially disadvantaged children in the Active-Start study.MethodA non-blinded randomized controlled trial was conducted in three public schools classified as highly vulnerable and located in a deprived area of Santiago (Chile). A total of 5 classes participated, totaling 170 fourth grade children. The intervention was delivered before starting the first school-class (8:00–8:30 a.m.). The program lasted for 8 weeks. Primary outcome measurement on bullying victimization was assessed by the CUBE questionnaire at baseline and post-intervention.ResultsThere was a statistically significant reduction in the probability of suffering physical bullying (OR= 0.18, 95% CI, 0.04-0.82; p= .027) and verbal bullying (OR=0.13, 95% CI, 0.02-0.97; p= .046) after the 8-week program.ConclusionsParticipation in an 8-week before-school physical activity intervention implemented in schools located in a disadvantaged district in Santiago (Chile) resulted in lower levels of bullying victimization among study participants. The Active-Start program may be a feasible and potentially scalable intervention option to improve the climate and pro-sociality environment at schools.  相似文献

The main purpose of the present study was to test the psychometric properties of the Satisfaction with Life Scale (SWLS) in a large sample of Spanish adolescents. The sample consisted of 1020 non-clinical adolescents with a mean age of 15.96 years (SD = 1.68). The level of internal consistency of the SWLS Total score by means of McDonald’s Omega was .85. The one-dimensional model displayed appropriate goodness of-fit indices. Strong measurement invariance for the one factor model across age and gender was found. Younger adolescents reported higher levels of life satisfaction. In addition, SWLS total score was negatively associated with behavioural and emotional. The study confirmed that the SWLS is a useful tool for the screening of self-reported life satisfaction in adolescents.  相似文献

My aim is to discuss the immediate effects of extreme trauma and to speculate on its long term effects. The formulations associated with the Post Traumatic Stress Syndrome generate an overly medicalized view of trauma, grossly underestimating its devastating impact. Catastrophic traumatic experience rips a hole in the representational continuity of psychic life; neither representations nor narrations are generated. Instead, a representational emptiness occurs, such that what has taken place cannot be shared or transmitted. The cathartic word becomes a robotic mocking of the interchange between human beings. There is no internalization, no ability to make the experience subjective. The resulting deep splitting in the psyche is characteristic of extreme traumatism, and its balance or perpetual working through is elaborated in this paper.  相似文献

This paper discusses an intriguing topic for psychoanalysis: the concept of unconscious communication. Beginning with the concept of unconscious perception, it moves on to figurability and culminates with reverie. Auxiliary concepts, such as receptive unconscious, intersubjectivtiy, countertransferrence and empathy, are discussed in order to articulate the conceptual network on which theoretical arguments are based.  相似文献

U.S. Latino parents can face cultural stressors in the form of acculturative stress, perceived discrimination, and a negative context of reception. It stands to reason that these cultural stressors may negatively impact Latino youth's emotional well‐being and health risk behaviors by increasing parents' depressive symptoms and compromising the overall functioning of the family. To test this possibility, we analyzed data from a six‐wave longitudinal study with 302 recently immigrated (<5 years in the United States) Latino parents (74% mothers, Mage = 41.09 years) and their adolescent children (47% female, Mage = 14.51 years). Results of a cross‐lagged analysis indicated that parent cultural stress predicted greater parent depressive symptoms (and not vice versa). Both parent cultural stress and depressive symptoms, in turn, predicted lower parent‐reported family functioning, which mediated the links from parent cultural stress and depressive symptoms to youth alcohol and cigarette use. Parent cultural stress also predicted lower youth‐reported family functioning, which mediated the link from parent cultural stress to youth self‐esteem. Finally, mediation analyses indicated that parent cultural stress predicted youth alcohol use by a way of parent depressive symptoms and parent‐reported family functioning. Our findings point to parent depressive symptoms and family functioning as key mediators in the links from parent cultural stress to youth emotional well‐being and health risk behaviors. We discuss implications for research and preventive interventions.  相似文献

This study focuses on lay conceptions of intelligence. It examined sex and cross‐cultural similarities and differences in estimated intelligences and beliefs about intelligence in two countries, Angola and East Timor, within the reversal theory framework. A total of 209 Angolan (109 women and 100 men) and 183 Timorese (89 women and 94 men) students were participated in this study. Participants completed a questionnaire in order to estimate their parents', partners' and own overall intelligence and the 8 reversal multiple intelligences (telic, paratelic, conformist, negativistic, autic mastery, autic sympathy, alloic mastery and alloic sympathy intelligence). Respondents also rated 6 questions about intelligence. Men rated their overall, conformist and autic mastery higher than women. Angolans rated their overall, telic, paratelic, conformist, negativistic, autic mastery, autic sympathy, alloic mastery and alloic sympathy intelligence higher than Timorese. In both countries, fathers have been perceived as more intelligent than mothers, and telic intelligence emerged as a significant predictor of overall intelligence. Principal component analysis of the 8 reversal multiple intelligences yielded one factor. Angolan participants revealed more IQ test experience than Timorese participants. Most of respondents in both countries did not believe in sex differences in intelligence. These findings are discussed by means of cross‐cultural literature.  相似文献
