The ability to anticipate the actions of opponents can be enhanced through perceptual-skill training, though there is doubt regarding the most effective form of doing so. We sought to evaluate whether perceptual-skill learning would be enhanced when supplemented with guiding visual information.
Twenty-eight participants without soccer-playing experience were assigned to a guided perceptual-training group (n = 9), an unguided perceptual-training group (n = 10), or a control group (n = 9). The guided perceptual-training group received half of their trials with color cueing that highlighted either the key kinematic changes in the kicker's action or the known visual search strategy of expert goalkeepers. The unguided perceptual-training group undertook an equal number of trials of practice, but all trials were without guidance. The control group undertook no training intervention. All participants completed an anticipation test immediately before and after the 7-day training intervention, as well as a 24-hr retention test.
The guided perceptual-training group significantly improved their response accuracy for anticipating the direction of soccer penalty kicks from preintervention to postintervention, whereas no change in performance was evident at posttest for either the unguided perceptual-training group or the control group. The superior performance of the guided perceptual-training group was preserved in the retention test and was confirmed when relative changes in response time were controlled using a covariate analysis.
Perceptual training supplemented with guiding information provides a level of improvement in perceptual anticipatory skill that is not seen without guidance.
通过感知技能训练,可以提高预测对手动作的能力,但对于最有效的训练形式仍存在争议。我们试图评估在补充引导视觉信息的情况下,感知技能学习是否会得到增强。
28 名没有足球经验的参与者被分配到有引导的感知训练组(n=9)、无引导的感知训练组(n=10)或对照组(n=9)。有引导的感知训练组在一半的试验中接受颜色提示,这些提示突出显示了踢球者动作中的关键运动学变化或守门员的已知视觉搜索策略。无引导的感知训练组进行了相同数量的练习试验,但所有试验都没有指导。对照组不进行任何训练干预。所有参与者在 7 天的训练干预前后以及 24 小时的保持测试中都完成了一个预测测试。
有引导的感知训练组在预测足球点球方向的反应准确性方面,从干预前到干预后显著提高,而无引导的感知训练组或对照组在干预后都没有表现出明显的变化。在保持测试中,有引导的感知训练组的表现得到了保留,并且当使用协变量分析控制反应时间的相对变化时,这种表现得到了证实。
在引导信息的补充下进行感知训练,可以提高感知预测技能的水平,而没有引导的情况下则不会出现这种情况。
