A computer-based modified Stroop color-word task was used as a cognitive task for 4 min. Priming effects were also examined. Alterations in cerebral oxygenated, deoxygenated, and total hemoglobin concentrations during two repetitive executions of the task, without noise and with a moderate/high level noise respectively, were measured in addition to the evaluation of cardiovascular-system response and personality traits. The results obtained in this study imply that individual differences in alterations in task performance under noise exposure are based on those in alterations by the noise condition in the cerebral hemodynamic and cardiovascular-system responses, which are considered to relate to personality traits.
