Subjective body position, as influenced by 21-day 6 • -head-down bed rest and intermittent supine centrifugation, was investigated in two experimental groups. Treatment subjects were exposed to a daily dose of 1-hour of horizontal centrifugation, whereas control subjects were also put on the centrifuge, but were not spun. During the centrifuge runs subjects were exposed to a constant gradient with 1-Gz at the heart and 2.5-Gz at the feet. Subjects reported their subjective postural position (SPP) before, during and after each 1-hour centrifuge exposure. We find that subjects shift their frame of reference over the first week of bed rest and perceive the 6 • -head-down position as horizontal. Spinning shifts the SPP by about 30 • towards an upright position, consistent with the angle of the gravito-inertial vector positioned close to the vestibular system. The SPP estimates for the upper and lower body failed to reflect the massive gravity gradient between head and feet, and subjects generally reported a single tilt for the whole body.

“…An important issue bearing on the formulation of a specific theoretica I model for body perception is whether adjustment of the rod parallel to the body is based upon a reference system involving the gravitational field and related to the perception of verticality or a reference system independent of the gravitational field as provisionally assumed, with Bauermeister, in this paper. For further pertinent data, see Baker, Cirillo and Wapner (1969).…”
