EEG Spectral Dynamics During Active Interaction with a Student Psychological Care Platform: A Resting-Baseline Study with Post-Task Usability, Workload, and Affective Measures

Digital platforms are increasingly used to support students’ psychological reflection and stress management, but their neurophysiological correlates remain unclear. This study examined EEG spectral dynamics during interaction with a student psychological care platform. Twenty-nine university students completed EEG recording during an eyes-open resting baseline and active platform interaction. Absolute power was used for topographic mapping, while relative spectral power was used for whole-scalp and ROI analyses across delta, theta, alpha, beta, and gamma bands. Post-task usability, workload, and affective responses were assessed using SUS, NASA-TLX, and SAM. Platform interaction was associated with significant modulation in delta, theta, beta, and gamma activity, with localized alpha effects in ROI analyses. Brain–behavior associations were limited, although beta activity was positively associated with perceived dominance. Findings should be interpreted as exploratory neurophysiological differences associated with active platform interaction rather than platform-specific psychological mechanisms.
