Executive functions (EFs) not only play an important role in shaping adolescent's goal-directed, future-oriented cognitive skills under relatively abstract, non-affective conditions (Cool EF), but also under motivationally significant, affective conditions (Hot EF). Empirical evidence suggest a link between EF, exercise and physical activity, specifically elite adult athletes appear to outperform amateur athletes in Cool EF; however, no previous studies have examined the relationship between Hot and Cool EFs and impulsivity during the developmentally sensitive period of adolescence comparing different types of sport (open- vs. closed-skills), and levels (elite athletes vs. amateurs).
A total 86 boys and girls between 13 and 15 years of age (mean: 14.0, : 0.79) from different sports (track-and-field; team handball) were recruited. Participants were further divided into two groups: (a) 40 elite, and (b) 46 amateur athletes. They completed four Cool EF tasks including Trail-Making Test, Trail-Walking-Test, Flanker task, n-back-task, and one Hot EF task on Game of Dice task. Data on subjective impulsivity (UPPS Impulsive Behavior Scale; Barratt Impulsiveness Scale-15) was also collected.
There was a significant overall effect for expertise in favor of elite athletes (Wilks' Lambda = 0.61, (14,69) = 3.19, = 0.001, = 0.393), but no overall main effect for type of sport or an interaction for expertise by type of sport. Specifically, elite athletes showed significantly better performances on dual tasks. For Hot EF, there were no main effects for type of sport, expertise level, training experience or training duration. We also found positive correlations among Cool EF and impulsivity measures, and between Hot EF and Impulsivity, but no significant relationship between Cool and Hot EF.
The current understanding of the decisive cognitive abilities does not correspond to sporting reality, so that the tests frequently used are not sensitive enough to distinguish between elite and amateur athletes or different sports. However, it should also be remembered that the factors underlying complex sporting performance are multidimensional and are obviously difficult to trace back to selected partial aspects. Without being able to answer this question conclusively, we proposed a 4-D classification of experimental paradigms, in which we differentiate between tasks of different specificity, between Cool and Hot EF, and between task complexity, and type of sport.
执行功能(EFs)不仅在相对抽象、非情感条件下(冷执行功能)塑造青少年目标导向、面向未来的认知技能方面发挥重要作用,而且在动机显著、情感条件下(热执行功能)也发挥重要作用。实证证据表明执行功能、锻炼和体育活动之间存在联系,具体而言,成年精英运动员在冷执行功能方面似乎优于业余运动员;然而,以前没有研究在青少年发育敏感期比较不同类型运动(开放技能与封闭技能)和水平(精英运动员与业余运动员)时,考察过热执行功能和冷执行功能与冲动性之间的关系。
招募了86名年龄在13至15岁之间(平均:14.0,标准差:0.79)来自不同运动项目(田径;团队手球)的男孩和女孩。参与者进一步分为两组:(a)40名精英运动员,和(b)46名业余运动员。他们完成了四项冷执行功能任务,包括连线测验、步道行走测验、侧翼任务、n-back任务,以及一项关于掷骰子任务的热执行功能任务。还收集了关于主观冲动性的数据(UPPS冲动行为量表;巴拉特冲动性量表-15)。
在专业水平方面存在显著的总体效应,有利于精英运动员(威尔克斯Lambda = 0.61,F(14,69) = 3.19,p = 0.001,η² = 0.393),但在运动类型方面没有总体主效应,也没有专业水平与运动类型的交互作用。具体而言,精英运动员在双重任务上表现明显更好。对于热执行功能,在运动类型、专业水平、训练经验或训练时长方面没有主效应。我们还发现冷执行功能与冲动性测量之间以及热执行功能与冲动性之间存在正相关,但冷执行功能和热执行功能之间没有显著关系。
目前对决定性认知能力的理解与体育现实不相符,以至于常用测试对区分精英和业余运动员或不同运动项目不够敏感。然而,还应记住,复杂运动表现背后的因素是多维度的,显然难以追溯到选定的部分方面。在无法确凿回答这个问题的情况下,我们提出了一种实验范式的四维分类,其中我们区分了不同特异性的任务、冷执行功能和热执行功能、任务复杂性以及运动类型。
