Judgements of body position during rotation in the sagittal plane were investigated at force magnitudes of 1·0, 1·2, 1·4, 1·6, and 1·8 g . With the head and trunk upright (Expt. I) the judgements were displaced forward as a function of the force operating. The forward shift could be related to the increase in the backward acting shear force on the utricular statolith organs. This hypothesis was supported by the reduced forward shift in perceived body position that occurred under the same conditions but with the head tilted 30° forward of the upright trunk (Expt. II).
