| Research Abstract |
Heart rate variability (HRV) of sixty-nine healthy male subjects (aged 20-49) were measured during rest and mental stress with special reference to the relationship between autonomic activity and personality. The personality was surveyed by a NEO-FFI (Five-Factor Inventory) which explores five personality factors ; Neuroticism (N), Extraversion (E), Openness (O), Agreeableness (A) and Conscientiousness (C). A multiple regression analysis indicated that a sympathetic indicatior of HRV (lnLF) during rest positively correlated with O-factor and negatively correlated with A-factor. On the other hand, lnLF during mental stress was associated with E-factor. The effect-sizes (β) of the personality fators on lnLF were approximated to be 0.25-0.40 which were equal to the effect of age.
