Three subjects were tilted 5, 15, 25, 35, 45, and 55 degrees in the lateral plane, and were maintained in these positions of lateral tilt for periods of 0, 5, 15, 25, 35, 45, 55, and 65 sec. prior to being allowed to return themselves to the gravitational vertical. Each subject was given 10 adjustments from each position of tilt and time of exposure, making 480 adjustments for each. Half of these adjustments were made from the left upper lateral quadrant and half from the right upper lateral quadrant. The adjustments were made during 20 exptl. sessions for each subject. With increasing duration of exposure to tilt there is an increasing avg: error of adjustment and a shift of constant error of adjustment in the direction of initial tilt. With increasing amount of initial tilt there is an increasing avg. error of adjustment and a shift of constant error in the direction of initial tilt. With increase in the duration of exposure to tilt and with increasing amounts of initial tilt there is no significant change in variability of either average or constant error. Results are related to previous work in this area, and curves are fitted to the empirical data. These curves are proposed as theoretical functions.
