| Research Abstract |
Alterations during two repetitive executions of a cognitive task, without noise and with low- or moderate/high-level noise were examined for cognitive-task performance, hemoglobin concentrations in the prefrontal association cortex, and cardiovascular-system response, and were analyzed, being focused on individual differences. The results show that individual differences in alterations in task performance under the noise condition depend on noise level and are based directly on psychological and personality traits, or indirectly on those via alterations by noise exposure in the cerebral hemodynamic or cardiovascular-system response, or in the both of them, which have related to psychological and personality traits. Consequently, the individual differences observed have been considered to originate in part from polymorphism in psychological and personality traits.
