This research explored how time pressure modulates human error generation and its neural correlates across personality dimensions. Using a dual-condition paradigm (pressure-free vs. time-pressured tasks), we analyzed subjective stress ratings, behavioral accuracy, and EEG recordings from 41 participants classified via the Big Five Personality Inventory. Results revealed that highly neurotic individuals exhibited amplified stress responses, marked by a pronounced Pe amplitude enhancement in error-related potentials, whereas error-related negativity (ERN) remained stable across conditions. Time-frequency decomposition showed suppressed alpha (8–12 Hz) and beta (13–30 Hz) oscillations during time-pressured tasks. Notably, openness levels significantly predicted beta-band energy variations under pressure, with high-openness individuals displaying distinct neural adaptability. These findings clarify the neurocognitive pathways linking time pressure to error monitoring and underscore the divergent roles of neuroticism (stress sensitivity) and openness (neural flexibility), offering an empirical basis for designing personalized training protocols to enhance cognitive resilience in time-critical scenarios.

摘要

This research explored how time pressure modulates human error generation and its neural correlates across personality dimensions. Using a dual-condition paradigm (pressure-free vs. time-pressured tasks), we analyzed subjective stress ratings, behavioral accuracy, and EEG recordings from 41 participants classified via the Big Five Personality Inventory. Results revealed that highly neurotic individuals exhibited amplified stress responses, marked by a pronounced Pe amplitude enhancement in error-related potentials, whereas error-related negativity (ERN) remained stable across conditions. Time-frequency decomposition showed suppressed alpha (8–12 Hz) and beta (13–30 Hz) oscillations during time-pressured tasks. Notably, openness levels significantly predicted beta-band energy variations under pressure, with high-openness individuals displaying distinct neural adaptability. These findings clarify the neurocognitive pathways linking time pressure to error monitoring and underscore the divergent roles of neuroticism (stress sensitivity) and openness (neural flexibility), offering an empirical basis for designing personalized training protocols to enhance cognitive resilience in time-critical scenarios.
