Adolescent–parent attachment characteristics and quality of youth sport friendship

ObjectivesTo examine the link between security of adolescent–parent attachment relationships and experiences of friendship quality in male team sport participants.Design and methodNinety six male adolescents involved in team sports completed self-report assessments of relationship security with a key parental attachment figure and of the nature of their friendship with a nominated sporting best friend. Teammates and coaches also provided ratings related to how easy they found it to get along with participants.ResultsResults provided evidence that the nature of the adolescent–parent attachment relationship was significantly related to sporting friendship experiences. More secure adolescent–parent attachment characteristics corresponded to more positive sporting friendships. Furthermore, sporting friendship dyads where both friends reported more secure attachment relations with parents were experienced more positively than dyads where both friends were less securely attached to parents or even where one friend was less securely attached.ConclusionThere is a suggestion that adolescent attachment relations with parents are indicative of underpinning working models of attachment that may subsequently influence the manner in which youngsters negotiate friendships in sporting contexts.     

Probabilities Associated with Precise and Vague Forecasts

Forecasts of future outcomes, such as the consequences of climate change, are given with different degrees of precision. Logically, more precise forecasts (e.g., a temperature increase of 3–4°) have a smaller probability of capturing the actual outcome than less precise forecasts (e.g., a temperature increase of 2–6°). Nevertheless, people often trust precise forecasts more than vague forecasts, perhaps because precision is associated with knowledge and expertise. In five experiments, we ask whether people expect highly confident forecasts to be associated with wider or narrower outcome ranges than less confident forecasts (Experiments 1, 2, and 5), and, conversely, whether they expect precise forecasts to be issued with higher or lower confidence than vague forecasts (Experiments 3 and 4). The results revealed two distinct ways of thinking about confidence intervals, labeled distributional (wide intervals seen as more probable than narrow intervals) and associative (wide intervals seen as more uncertain than narrow intervals). Distributional responses occurred somewhat more often in within‐subjects designs, where wide and narrow prediction intervals and high and low probability estimates can be directly compared, whereas separate evaluations (in between‐subjects design) suggested associative responses to be slightly more frequent. These findings are relevant for experts communicating forecasts through confidence intervals. Copyright © 2017 John Wiley & Sons, Ltd.     

Ethical Codes in Sports Organizations: An Empirical Study on Determinants of Effectiveness

Confronted with numerous scandals, sports organizations are turning to the adoption of ethical codes to attain more ethical behavior. However, the effectiveness of an ethical code as a means to increase ethical behavior remains debated; furthermore, the particular characteristics of a sports context have not yet been taken into account, nor have the different stages of code establishment been considered in evaluation. This article studies the effectiveness, as measured by the Ethical Climate Index, of ethical codes in sports organizations. Moreover, it investigates the effects of the presence, creation, content, implementation, and enforcement of ethical codes on ethical behavior in sports organizations. Our results shed a light on the conditions that need to be in place to install an effective ethical code in sports organizations: a genuine motivation to improve ethical behavior, the involvement of coaches, and the explicit targeting of the management.     

Understanding injuries in sports: Self-reported injury and perceived risk of injury among adolescents

IntroductionAlthough exposure and perceived risk of injury in sports among adolescents is a well-known phenomenon today, their understanding remains poorly explored.ObjectiveThis study examines the relationships between demographics, sport motives, and sport-related characteristics in a sample of French adolescents involved in sports.MethodsThe sample included 394 adolescents involved in sports, between 13 and 19 years old. The adolescents filled out a questionnaire requesting information about their age, sex, sport motives, sport-related characteristics, the number of injuries, and perceived risk of injury in their preferred sport.ResultsThe findings showed that the number of injuries was related to age, sex, type of sport and the participant's motives. The will to play to the limit increased with the exposure to injury. Participation in risky sports and the will to play to the limit were predictors of the adolescents’ risk of exposure to sports injuries. Time devoted to sports appears to be a confounding factor. Moreover, boys exhibited higher number of injuries than girls, and they perceived their preferred sport as riskier.ConclusionExposure to the risk of injury in sports and the exacerbated perception of that risk may provide a means of enhancing one's self-image, procuring an emotional experience, and constructing one's masculinity.

The Application of Cortical Arousal Assessment to Control Neuromuscular Fatigue During Strength Training

The author's aim was to analyze the cortical arousal response during a conventional strength training session as a method to assess central nervous system fatigue. Sixteen trained men were recruited to perform the maximum number of training series composed of 6 exercises of 10 repetition each, at the intensity of 70% of the 1 maximum repetition, with a rest period of 2 min between exercises and 5 min between series, until exhaustion. Cortical arousal was measured using the critical flicker fusion threshold before, after warm-up, after each exercises series, after the recovery phase between series, and 15 min and 30 min after finishing the training session. Participants could not finish the fourth series of exercise, corresponding with a significant decrease of cortical arousal respect to the warm-up value. The assessment of cortical arousal using CFFT during a strength training session could be a fast and efficient method for assessing central nervous fatigue. Practically, coaches could modify the training protocol according to the individual cortical arousal response in order to improve training efficiency and prevent injuries.     

Can emotional content reduce the age gap in visual working memory? Evidence from two tasks

Ageing is associated with declines in several cognitive abilities including working memory (WM). The goal of the present study was to assess whether emotional information could reduce the age gap in the quantity and quality (precision) of representations in visual WM. Young and older adults completed a serial image recognition (SIR) task and a colour-image binding (CIB) task. Results of the SIR task showed worse performance for negative than neutral and positive images within the older group, hence enlarging the age gap in WM. In the CIB task, recall precision was lower in the old than young adults, showing an ageing decline in the quality of WM representations. Positive images tended to improve precision, but this boost was similar for both age groups. In sum, emotional content did not reduce the age gap in visual WM.     

High-level Enactive and Embodied Cognition in Expert Sport Performance

Abstract

Mental representation has long been central to standard accounts of action and cognition generally, and in the context of sport. We argue for an enactive and embodied account that rejects the idea that representation is necessary for cognition, and posit instead that cognition arises, or is enacted, in certain types of interactions between organisms and their environment. More specifically, we argue that enactive theories explain some kinds of high-level cognition, those that underlie some of the best performances in sport and similar practices (dance, martial arts), better than representational accounts. Flow and mushin (mindfully fluid awareness) are explained enactively to this end. This results in a mutually beneficial analysis where enactivism offers theoretical and practical advantages as an explanation of high performance in sports, while the latter validates enactivism.     

On the Compatibility of Brain Enhancement and the Internal Values of Sport

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.     

A discussion of Kretchmar’s elements of competition

Recently Kretchmar attempted to apply and to explore Husserl’s transcendental phenomenological method in relation to clarifying, in the context of sport particularly, the main features of competition. He concludes with the strong claim that competition is unintelligible unless understood in relation to the four elements of plurality, comparison, normativity, and disputation. Roughly, the idea is that competition needs to be understood as a context in which more than one competitor is involved; where competitors are compared; that comparisons are evaluations of their performance/entry in the competition; and that the expected result of the latter is a matter of dispute between or among contestants. In investigating these points some refinement of this basic outline is attempted against occasional reference to others who in the past made similar claims about the conditions of competition. I conclude that Kretchmar’s claims are mistaken.
