On the premise of gender difference, it is an important issue to concern about work right and treatment for gender differences. Until now, very little has been known about the psychophysiological mechanisms underlying mental fatigue eat various mental workloads for gender differences. Many studies attempt to further more explore the mechanism of mental fatigue under mental workloads for gender differences. While there are many questions need to clear for that between gender differences. The purpose of this study is to explore the recognition function and arousal level at various mental workloads for gender differences. To examine the difference mentioned above by using Electroencephalogram (EEG) incorporated NASA-TLX rating scale subjective measuring. The analysis data included Event-Related Potential (ERP) and EEG power spectrum for evaluating recognition function and arousal level respectively. Ten male and ten female are recruited voluntary subjects to participate the study. The subject’s ERP and NASA-TLX rating scale were undertaken before experiment task. Four sessions of colored-cube calculating tasks served as four different level of workload were performed during experimental tests. The subjects’ EEGs were recorded during experimental tasks. The subject’s ERP and NASA-TLX rating scale were undertaken after experiment tasks again. The preliminary result revealed the EEG power spectrum and ERP of female had more significant differences than those of male after experimental tasks. While NASA-TLX rating scale of male had more significant differences than those of female after experimental tasks. It means that female is more sensitive in physiological response under mental workload than male. For subjective self-evaluation, male is more apparent under mental workload than female. The result is potentially applicable to occupational health associated with fatigue management and work arrangement for gender differences.
