TACTILE STIMULATION AND PERCEPTION OF THE VERTICAL

NYBORG, H. Tactile stimulation and perception of the vertical. I. Effects of diffuse vs. specific tactile stimulation. Scand. J. Psychol. , 1971, 12, 1–13. – It was found that tactile stimulation influenced perception of verticality. Perception of verticality was tested by means of Rod-and-Frame Test, standard procedure. During tilted standing, subjects were exposed to diffuse tactile stimulation (DBR) or specific tactile stimulation (SBR) by means of a specially built apparatus. On the average, subjects scored closer to the physical vertical during SBR than during DBR.
