Susceptibility to motion sickness and field dependence-independence as measured with the rod and frame test.

This paper reports an experiment investigating the relationship between field dependence-independence and susceptibility to motion sickness in a normal volunteer and in a psychiatric patient population. Both variables have previously been related to psychiatric diagnosis and possible differential interaction between the cerebral hemispheres. Anticipated differences in field dependence according to degrees of motion sickness were not found; however, significant male-female and patient-control differences were observed and these occurred primarily in the non-motion sick and intermediate motion sick groups, suggesting that fundamental differences in field attitude do exist across in apparent spectrum of motion sickness.
