The older,the wider: On-field tactical behavior of elite-standard youth soccer players in small-sided games

PurposeYoung soccer players need excellent tactical skills to reach the top. Tactical behavior emerges through interactions between opposing teams. However, few studies have focused on on-field tactical behavior of teams with talented soccer players. Therefore, this study aimed to determine teams’ tactical behavior during small-sided games in two age categories, Under-17 and Under-19.MethodsPositional data of thirty-nine elite-standard soccer players were collected during twenty-four small-sided games to calculate longitudinal and lateral inter-team distances, stretch indices and length per width ratios. Corresponding interaction patterns and game-to-game variability were also determined.ResultsUnder-19 showed a significantly larger lateral stretch index and a significantly lower length per width ratio compared with Under-17. Furthermore, teams of both age groups showed similar large proportions of in-phase behavior. Variability of tactical performance measures within and between games was similar for Under-17 and Under-19.ConclusionsVariability within games seems to be functional for attacking teams for creating goal-scoring opportunities. In conclusion, the main difference was that Under-19 adopted a wider pitch dispersion than Under-17, represented by a larger lateral stretch index and smaller length per width ratio. Coach instructions and training exercises should be directed at exploiting pitch width to increase the pursuit of goal-scoring.     

Affective consequences of optimism and pessimism in the face of failure: Evidence of a moderation by attribution

The present experiment set out to investigate the affective consequences of dispositional optimism and attribution in performance settings. Optimistic and pessimistic participants (N = 42 each) experienced failure at solving two cognitive tasks in an alleged team setting. The failure could either be attributed to themselves (internal condition) or a teammate (external condition). We found disordinal interactions of optimism and attribution on the feelings of success and feelings of failure. While the affective state of optimists deteriorated significantly if they attributed the failure internally compared to externally, pessimists were emotionally unaffected by the locus of attribution. Moreover, optimists experienced affective benefits compared to pessimists when they attributed the outcome externally. The reverse was true if they had attributed internally. Affective consequences of optimism and pessimism after failure therefore seem to differ depending on attributions. Furthermore, pessimists seemed to be unresponsive to the affective effects of attribution in our study. This insensitiveness implies differences in the cognitive processing of outcomes, a trait × cognition interaction that should be investigated further.     

How self-transcendence via individualised moral foundations predict emotional and social enhancement

In this article we focus on explaining personality trait self-transcendence (ST) in relation to social and emotional competence, and suggest that ST through differences in moral foundations can partially predict social and emotional competence. A sample of 195 university students was used to test hypotheses regarding several paths between ST, trait emotional intelligence (EI), universalism and moral foundations. Consistent with the hypotheses, ST was found to predict social and emotional competence via individualised moral foundations (IMF). Results have implications for our understanding of the relationship between ST, moral foundations, social and emotional competence.     

A British university case study of the transitional experiences of student-athletes

ObjectivesWithin Great Britain, increasing numbers of elite sport performers are attending higher education institutions. The current study presents an exploration of the transitional experiences of these individuals at a specific British university. Wylleman and Lavallee's (2004) developmental model on transitions faced by athletes and Stambulova's (1997, 2003) athletic career transition model were used to provide the theoretical foundation of inquiry.Design and methodAn instrumental case study design was adopted to provide an in-depth analysis of student-athletes’ experiences at a university. The case university was selected based on its provision of elite sport support services. To acquire a holistic understanding, interviews were conducted with current and recently graduated student-athletes from the university, and focus groups were run with university staff (viz. administrators, coaches, and support staff). Qualitative data were analyzed using a thematic framework approach.ResultsElite student-athletes at the British university were found to experience simultaneous athletic, academic, psychological, and psychosocial transitions. To overcome the transitional demands, student-athletes were found to draw on a variety of internal (e.g., self-awareness) and external (e.g., academic flexibility) resources and to implement coping strategies (e.g., seeking social support). Potential barriers to successful transitions were also identified (e.g., parental overprotection).ConclusionsThese findings advance the limited existing literature on British university student-athletes’ transitional experiences and suggestions are provided for how other universities can enhance provision for their elite student-athletes.     

Imposing Genetic Diversity

The idea that a world in which everyone was born “perfect” would be a world in which something valuable was missing often comes up in debates about the ethics of technologies of prenatal testing and preimplantation genetic diagnosis (PGD). This thought plays an important role in the “disability critique” of prenatal testing. However, the idea that human genetic variation is an important good with significant benefits for society at large is also embraced by a wide range of figures writing in the bioethics literature, including some who are notoriously hostile to the idea that we should not select against disability. By developing a number of thought experiments wherein we are to contemplate increasing genetic diversity from a lower baseline in order to secure this value, I argue that this powerful intuition is more problematic than is generally recognized, especially where the price of diversity is the well-being of particular individuals.     

目标决策还是动作诱发?动作反应对注意促进效应的影响

注意促进效应(ABE)指的是在双任务条件下, 伴随探测任务的目标刺激呈现的背景信息记忆成绩要优于伴随分心刺激呈现的背景信息记忆成绩的现象。以往研究主张, ABE的产生主要源于目标决策时所诱发的注意增强。但由于目标探测往往伴随着动作反应, 而已有研究发现, 动作反应就能直接诱发背景信息的记忆增强效应, 因此ABE也可能源于动作诱发的记忆增强效应。为此, 研究设置了NoGo目标探测条件与Go目标探测条件, 通过4个实验系统地探讨了动作反应与目标决策在ABE产生中的作用及关系。结果表明, Go目标探测条件下的ABE是稳定的, 但NoGo目标探测条件下的ABE会受到动作反应频率对分心词的影响。此外, NoGo目标探测跨条件的ABE也是非常稳定的。这些结果表明, 目标决策产生的注意促进作用是相对稳定的, 但ABE的产生更多是目标决策的促进作用与动作诱发的记忆增强效应动态权衡后的结果。     

A conceptual model for mental health and performance of North American athletes: A mixed methods study

ObjectiveThe demands of sport create psychological and physical challenges for athletes, making it essential to understand what factors contribute to mental health and performance optimization in sport. The purpose of this mixed-methods investigation was to develop a conceptual model for mental health and performance of North American athletes.MethodForty-three experienced athletes, coaches, and sport professionals identified, sorted, and rated 113 behaviors, thoughts, and feelings that contribute to optimal mental health and performance for athletes. Using Multidimensional Scaling, the research team created a two-dimensional point map of participant responses. Hierarchical Cluster Analysis was then used to reveal underlying clusters in the data.FindingsSeven clusters emerged from the data: Stress Management, Mental Skills, Self-Awareness, Managing Setbacks, Intentional Practice, Team Relationships, and Social Support. Though all clusters were rated as important to mental health and/or performance, the Managing Setbacks cluster displayed high importance ratings for both mental health and performance.ConclusionOur preliminary findings suggest a comprehensive approach to athlete thoughts, feelings, and behaviors contributes to optimal mental health and performance for North American athletes.
