Abstract : To determine the effect of transient weightlessness on binocular depth perception, five subjects were tested under three levels of gravity--0 G, 1 G, and 2 G--produced by flying a JC-131B aircraft through appropriate maneuvers. A modified Howard-Dolman depth perception apparatus was installed in the aircraft. The experimenter set one of three rods forward or backward 1, 2, 3, 4, 5, or 6 cm from the other two rods. Each of the six distance intervals was randomly assigned to one rod position and direction of displacement. The subjects then reported for each trial whether the rods appeared to be equally distant or whether one appeared to be in front or back of the other two. Results indicated that binocular depth perception was not appreciably affected by the three different gravity conditions. (Author)
