- Heart rate;
- Skin resistance;
Heart rate and skin resistance indices were obtained from 30 introverts and 30 extraverts as they performed on one of three levels of a visual vigilance task. Introverts detected more signals than did extraverts during the vigilance task. This superiority by introverts was associated with a pattern of heart rate and electrodermal activity which supported H. J. Eysenck's (1967) theoretical formulation.
