Abstract: Under the guidance of the "High-tech Olympics" concept, literature review is used to explore the field of psychological sci-tech research from the perspective of cognitive neuroscience. It is stated that psychological sci-tech service aims to "enhance performance stability" by integrating cognitive neuroscience techniques with psychological services, with the features of quantifying neural activities during sports performance, identifying psychological risks before competitions and regulating athletes' mental abilities during competition. The implementation process of the services relies on the fundamental principles of action control to quantify, iterate, and monitor its effectiveness in real time by utilizing cognitive neuroscience techniques, big data, artificial intelligence algorithms and other tools. Its application pathway involves mobile electroencephalography and wireless transmission as vehicles, employing coding interfaces and service platforms to fit multi-dimensional and multi-modal physiological and psychological data, thus to dynamically monitor and adjust athletes' mental states. Psychological sci-tech services are transforming from experiential-driven to data-driven iterative development, paving the way for increased precision and efficiency in psychological services, ultimately supporting athletes in achieving stable performance during competitions.
