Fast motor reactions in sports often require the ability to predict the intended action of an opponent as early as possible. Therefore, the present paper investigates whether beach volleyball athletes are able to recognize different attack hits (i.e. smash vs. poke shot) at an earlier stage of the movement than novices. Beach volleyball athletes and novices took part in a response priming experiment (Experiment 1). Participants had to decide whether a presented target picture depicts a smash or a poke shot. Importantly, the preceding prime pictures were taken from different stages of the movements varying between the jump (beginning of the movements) and the hand-ball contact (end of the movements). Diverging response congruency effects was found for athletes and novices. Athletes were able to recognize at an earlier movement stage than novices which kind of attack hit was shown at the prime picture. It is suggested that athletes might implicitly read movement-related patterns in the depicted athlete's body posture (e.g. the angle of the elbow). In contrast, novices might use information which is easier to access (e.g. hand-ball relation). In a second experiment, novice participants received a visual training to test for a potential perceptual source of the priming effects. Notably, participants did not improve their ability to differentiate the volleyball techniques, indicating that a better recognition performance in athletes is based on motor and not on perceptual expertise.
快速的运动反应在体育运动中常常需要运动员尽早预测对手的意图动作。因此,本研究调查了沙滩排球运动员是否能够比新手更早地识别不同的攻击击球(即扣球和吊球)。沙滩排球运动员和新手参加了一个反应启动实验(实验 1)。参与者必须判断呈现的目标图片是否描绘了扣球或吊球。重要的是,前面的启动图片取自不同的运动阶段,从起跳(运动开始)到击球(运动结束)。运动员和新手的反应一致性效应不同。运动员能够比新手更早地识别出启动图片中展示的是哪种攻击击球。这表明运动员可能会在身体姿势(如肘部角度)中隐含地读取与运动相关的模式。相比之下,新手可能会使用更容易获取的信息(例如手球关系)。在第二个实验中,新手参与者接受了视觉训练,以测试潜在的启动效应的知觉来源。值得注意的是,参与者并没有提高他们区分排球技术的能力,这表明运动员更好的识别表现是基于运动而不是知觉专长。
