Abstract:

The automatic nervous system is made up of two subsystems the parasympathetic PNS and the sympathetic SNS. The balance between these systems regulates bodily functioning during routine PNS-dominant and crisis SNS-dominant situations. It also controls visual accommodation for near PNS-dominant and far SNS-dominant focus. The balance between these physiological systems has been linked to individual differences in personality characteristics, especially introversion PNS-dominant and extraversion SNS-dominant. Since the balance mediates accommodation, the similar personality differences between near- and far-sighted individuals may be related to the more general parasympathetic-sympathetic balance rather than being related solely to the visual capability difference. The relationships among autonomic balance as measured by a battery of four physiological tests modified from Wenger and Ellington, 1943, and by a technique introduced by Porges, 1976, refractive error measured by dark focus, near and far points using a polarized vernier optometer, and introversion - extraversion Eysenck Personality Inventory introversion - extraversion scale core were investigated.
