CATECHOLAMINE EXCRETION, PERFORMANCE, AND SUBJECTIVE STRESS

Abstract
Psycho‐endocrine relations were explored in 52 students exposed to moderately stressful psychological tests demanding selective attention. Subjects with high excretion rates of adrenaline performed better during the entire stress session than did subjects with low adrenaline excretion. The level of subjective stress increased consistently throughout the session in subjects with low excretion rates of adrenaline, while it remained relatively constant in subjects with high adrenaline excretion. No consistent relationship could be demonstrated between noradrenaline excretion and the psychological variables. Possible effects on the catecholamine‐excretion patterns of factors such as severity and duration of the stress are discussed.
