Alertness and clear thinking as characteristics of high naturally occurring autonomic nervous system arousal.
Studies of the effect of induced mood on the autonomic nervous system (ANS) suggested that naturally occurring mood might also covary with the ANS. Ss were 13 men and women aged 20 to 70. Fatigue, confusion, and depression were measured on the Profile of Mood States, while barometric pressure and the ANS indices of heart rate and body temperature were also recorded. Fatigue and confusion each showed negative relationships to both heart rate and body temperature. Barometric pressure showed a suggestively positive relationship to the mood of depression. Hypothalamic serotonin concentration was suggested as a central factor producing the covariations between the mood indices (alertness and clear thinking) and the ANS measures.
