PERCEPTION OF POSTURAL VERTICALITY. EFFECTS OF FLYING EXPERIENCE UPON REDUCTION OF ERROR
Abstract
Test pilots were compared with nonflyers in their ability to estimate a function of the postural vertical. To minimize kinesthetic cues, the subjects were asked to bisect an angle between 30 degrees left body tilt and the vertical with visual references eliminated. The analysis of the average error and slope for each day of 3 daily sessions showed no differences between the experimental groups. However, a significant reduction in error demonstrated habituation over the 3-day period with a uniform linear reduction within each day. Therefore, habituation was demonstrated for all subjects, but flying experience seems to have no relationship to a person's reduction of error in estimating a function of the postural vertical.
