    Summary

    Continuous cognitive tasks decrease alertness. Electroencephalogram (EEG) analysis shows increased fatigue and reduced alertness by measuring EEG frequency band energy during cognitive tasks.

    Area of Science:

    • Neuroscience
    • Cognitive Psychology
    • Human Factors Engineering

    Background:

    • Sustained cognitive task performance often leads to decreased alertness.
    • Electroencephalogram (EEG) changes are recognized as potential biomarkers for monitoring alertness levels.
    • Previous research suggests a link between EEG patterns and cognitive load.

    Purpose of the Study:

    • To investigate the impact of continuous cognitive task performance on alertness.
    • To quantify the increase in fatigue levels during prolonged cognitive engagement.
    • To analyze changes in EEG frequency band energy as indicators of alertness decline.

    Main Methods:

    • Subjects performed continuous cognitive tasks.
    • Electroencephalogram (EEG) data was recorded throughout the task performance.
    • Analysis focused on changes in the energy of different EEG frequency bands.
    • Cognitive loading was systematically varied.

    Main Results:

    • A gradual increase in subject fatigue levels was observed with extended task duration.
    • EEG parameters showed trends indicative of a progressive drop in alertness.
    • Increased cognitive loading correlated with more pronounced changes in EEG energy.
    • Specific EEG frequency bands demonstrated significant alterations corresponding to fatigue.

    Conclusions:

    • Continuous cognitive task performance significantly elevates fatigue and reduces alertness.
    • EEG frequency band energy analysis provides a reliable method for detecting fatigue-induced alertness decrements.
    • Cognitive loading intensity influences the rate and extent of alertness decline.
    • Findings have implications for optimizing work schedules and managing cognitive performance in demanding environments.
