Tennis is a skill-oriented antagonistic net-separating sport. It requires players to change speed and give responses very quickly and make accurate judgments and decisions on the path of the ball. Based on electroencephalography (EEG), this paper assigns general-situation and specific-situation decision making tasks to tennis players and college students, and analyzes the cognitive mechanisms of tennis players. The experimental results show that: college students’ decision-making response time was obviously longer than that of the player group, and that the decision scores and accuracy of the player group were significantly higher than those of the college student group. After specialized training, tennis players had intuitions when making decisions. Their intuitive decision-making abilities were much stronger than those of the college student group. Due to the spatial positioning or stimulatory interference suppression effects of the players’ brains, stimulus conditions induced P1 and P2 waveforms, and with the peak amplitude increasing and the latency period becoming longer, such phenomena of the player group were increasingly obviou
