Experiments on sensory-tonic field theory of perception: V. Effect of body status on the kinesthetic perception of verticality.

Abstract

To study the effect of head and body tilt and concentric body rotation on the kinesthetic perception of verticality, blindfolded Ss adjusted a rod pivoted at the lower end to the vertical by moving the fingers of both hands along the rod. The results are essentially identical with those found for visual perception of the vertical in that the position of the rod that appeared vertical was objectively tilted when the head and body were tilted right, the body was accelerated around the vertical axis in the clockwise direction, and when the body was decelerated from constant counterclockwise rotation.
