Effect of brief sensory deprivation on field dependence.

To determine whether brief sensory deprivation (SD) would act to decrease perceptual field dependence, 41 male and female college students were given the Rod and Frame Test (RFT). 1 of the group then underwent 1 hr. of SD, after which a 2nd RFT indicated a significant decrease (p < .01) in errors of orientation. The control group was given the RFT and their activity was controlled during the 1 hr. interval. Their 2nd RFT showed no significant changes in performance. The posttest error-reduction difference between the 2 groups was significant at p < .OS. The results were explained on the basis of increases in awareness of bodily sensations and their availability for use in orientation tasks.
