Mental workload was assessed using NASA-TLX, Heart Rate Variability (HRV), and EEG-based Beta-Alpha Ratios (BAR) across frontal (F3, F4), parietal (P3, P4), and occipital (O1, O2) regions. Performance in document preparation (Task 1) and arithmetic operations (Task 2) was evaluated using percentage-based accuracy, efficiency, and overall performance scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Result<\/jats:title>\n                    <jats:p>AI intervention improved overall task performance but was accompanied by an apparent performance\u2013workload paradox, whereby enhanced output coincided with increased neurophysiological and systemic strain. Descriptively, NASA-TLX Overall Perceived Workload decreased from 54.05 to 44.91 during complex tasks, while HRV declined by 48.68% in Task 1, indicating acute autonomic strain. EEG revealed increased BAR in the frontal (F3: 29.2%), parietal (P3), and occipital (O1) regions, suggesting heightened attentional and sensory demands associated with monitoring and verifying AI-generated suggestions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>AI redistributes rather than eliminates workload, increasing executive verification and visual monitoring demands.
