Having investigated the decision making of world class elite and subelite athletes (see Parkin and Walsh, 2017; Parkin et al., 2017), here the abilities of those at the earliest stage of entry to elite sport are examined. Junior elite athletes have undergone initial national selection and are younger than athletes examined previously (mean age 13 years). Decision making under mental pressure is explored in this sample. During performance an athlete encounters a wide array of mental pressures; these include the psychological impact of errors, negative feedback, and requirements for sustained attention in a dynamic environment (Anshel and Wells, 2000; Mellalieu et al., 2009). Such factors increase the cognitive demands of the athletes, inducing distracting anxiety-related thoughts known as rumination (Beilock and Gray, 2007). Mental pressure has been shown to reduce performance of decision-making tasks where reward and loss contingencies are explicit, with a shift toward increased risk taking (Pabst et al., 2013; Starcke et al., 2011). Mental pressure has been shown to be detrimental to decision-making speed in comparison to physical stress, highlighting the importance of considering a range of different pressures encountered by athletes (Hepler, 2015).
To investigate the influence of mental pressure on key indicators of decision making in junior elite athletes. This chapter concludes a wider project examining decision making across developmental stages in elite sport. The work further explores how psychological insights can be applied in an elite sporting environment and in particular tailored to the requirements of junior athletes.
Seventeen junior elite athletes (10 males, mean age: 13.80 years) enrolled on a national youth athletic development program participated in the study. Performance across three categories of decision making was assessed under conditions of low and high mental pressure. Decision making under risk was measured via the Cambridge Gambling Task (CGT; Rogers et al., 1999), decision making under uncertainty via the Balloon Analogue Risk Task (BART; Lejuez et al., 2002), and fast reactive responses to perceptual stimuli via the Visual Search Task (Treisman, 1982). Mental pressure was induced with the addition of a concurrent verbal memory task, used to increase cognitive load and mimic the distracting effects of anxiety-related rumination.
In junior elite athletes, fast reactive responses to perceptual stimuli (on the Visual Search Task) were slower under conditions of mental pressure. For decision making under risk there was an interaction of mental pressure and gender on the amount of points gambled, under pressure there was a higher level of risk taking in male athletes compared to females. There was no influence of mental pressure on decision making under uncertainity. There were no significant correlations in the degree to which individual's responses changed under pressure across the three measures of decision making. When assessing the applicability of results based on group averages there were no junior elite athletes who showed an "average" response (within 1SD of the mean) to mental pressure across all the three decision-making tasks.
Mental pressure affects decision making in a sample of junior elite athletes, with a slowing of response times, and modulations to performance of decision making under risk that have a high requirement for working memory. In relation to sport, these findings suggest that novel situations that place high cognitive demands on the athlete may be particularly influenced by mental pressure. The application of this work in junior elite athletes included the feedback of individual results and the implementation of a decision-making taxonomy.
在对世界级精英和次精英运动员的决策进行研究之后(见帕金和沃尔什,2017年;帕金等人,2017年),本文考察了那些处于进入精英运动最早阶段的运动员的能力。青少年精英运动员已经历了初步的国家选拔,且比之前研究的运动员更年轻(平均年龄13岁)。本研究样本探讨了在心理压力下的决策。在比赛过程中,运动员会遇到各种各样的心理压力;这些压力包括失误的心理影响、负面反馈以及在动态环境中持续保持注意力的要求(安舍尔和韦尔斯,2000年;梅拉利厄等人,2009年)。这些因素增加了运动员的认知需求,引发了被称为反刍的与焦虑相关的分心想法(贝洛克和格雷,2007年)。研究表明,在奖励和损失情况明确的决策任务中,心理压力会降低表现,并导致冒险行为增加(帕布斯特等人,2013年;斯塔克等人,2011年)。与身体压力相比,心理压力已被证明对决策速度有不利影响,这凸显了考虑运动员所面临的一系列不同压力的重要性(赫普勒,2015年)。
研究心理压力对青少年精英运动员决策关键指标的影响。本章总结了一个更广泛的项目,该项目考察了精英运动不同发展阶段的决策情况。这项工作进一步探索了如何将心理学见解应用于精英运动环境,特别是如何根据青少年运动员的需求进行调整。
17名参加国家青少年体育发展项目的青少年精英运动员(10名男性,平均年龄:13.80岁)参与了本研究。在低心理压力和高心理压力条件下,评估了三类决策的表现。通过剑桥赌博任务(CGT;罗杰斯等人,1999年)测量风险决策,通过气球模拟风险任务(BART;勒朱兹等人,2002年)测量不确定决策,通过视觉搜索任务(特雷斯曼,1982年)测量对感知刺激的快速反应。通过增加一个并发的言语记忆任务来诱导心理压力,该任务用于增加认知负荷并模拟与焦虑相关的反刍的干扰效应。
在青少年精英运动员中,在心理压力条件下,对感知刺激的快速反应(在视觉搜索任务中)较慢。对于风险决策,心理压力和性别在赌博点数上存在交互作用,在压力下,男性运动员比女性运动员有更高的冒险水平。心理压力对不确定决策没有影响。在三种决策测量中,个体反应在压力下变化的程度之间没有显著相关性。在根据群体平均值评估结果的适用性时,没有青少年精英运动员在所有三项决策任务中对心理压力表现出“平均”反应(在平均值的1个标准差范围内)。
心理压力会影响青少年精英运动员样本的决策,反应时间会变慢,对工作记忆要求较高的风险决策表现也会受到调节。就运动而言,这些发现表明,对运动员认知要求较高的新情况可能特别容易受到心理压力的影响。这项工作在青少年精英运动员中的应用包括个人结果的反馈以及决策分类法的实施。
