The ability to form anticipatory representations of ongoing actions is crucial for effective interactions in dynamic environments. In sports, elite athletes exhibit greater ability than novices in predicting other players' actions, mainly based on reading their body kinematics. This superior perceptual ability has been associated with a modulation of visual and motor areas by visual and motor expertise. Here, we investigated the causative role of visual and motor action representations in experts' ability to predict the outcome of soccer actions. We asked expert soccer players (outfield players and goalkeepers) and novices to predict the direction of the ball after perceiving the initial phases of penalty kicks that contained or not incongruent body kinematics. During the task, we applied repetitive transcranial magnetic stimulation (rTMS) over the superior temporal sulcus (STS) and the dorsal premotor cortex (PMd). Results showed that STS-rTMS disrupted performance in both experts and novices, especially in those with greater visual expertise (i.e. goalkeepers). Conversely, PMd-rTMS impaired performance only in expert players (i.e. outfield players and goalkeepers), who exhibit strong motor expertise into facing domain-specific actions in soccer games. These results provide causative evidence of the complimentary functional role of visual and motor action representations in experts' action prediction.
对正在进行的动作形成预期表征的能力对于在动态环境中进行有效的互动至关重要。在体育领域,精英运动员在预测其他运动员动作方面比新手表现出更强的能力,这主要基于对他们身体运动学的解读。这种卓越的感知能力与视觉和运动专业知识对视觉和运动区域的调节有关。在此,我们研究了视觉和运动动作表征在专家预测足球动作结果能力中的因果作用。我们让专业足球运动员(场上球员和守门员)和新手在感知包含或不包含不一致身体运动学的点球初始阶段后预测球的方向。在任务过程中,我们在颞上沟(STS)和背侧运动前皮质(PMd)上施加重复经颅磁刺激(rTMS)。结果表明,STS-rTMS破坏了专家和新手的表现,尤其是在视觉专业知识更强的人群(即守门员)中。相反,PMd-rTMS仅损害了专家球员(即场上球员和守门员)的表现,他们在足球比赛中面对特定领域动作时表现出很强的运动专业知识。这些结果为视觉和运动动作表征在专家动作预测中的互补功能作用提供了因果证据。
