In this paper, event-related potential (ERP) technology is used to study the distribution of attention resources of tennis related information by tennis experts, and to preliminarily explore the reasons for the perception advantages of sports experts. The study included two separate experiments. In the first experiment, the pointprobing paradigm was used to study the response time of attention bias characteristics under different emotions. In the second experiment, ERP technology was used to study the attention resources allocation method of tennis experts to the tennis scene, trying to explain the expert's attention advantage from the perspective of central nervous system. Through this study, we find that for the tennis experts, there is an attention competition between the tennis scenes and the negative emotional faces, which shows that in the presence of attention competition, tennis experts will have a higher attention level to the scene information related to professional skills; sports experts have an attention bias tendency to skill-related scene information, which may be the mechanism behind the phenomenon that “experts can process scene information faster or at a higher level”.
