Title / Titel Optic-vestibular interaction in the information processing structure of the subjective vertical
PDF Abstract (PDF, 14 KB)
Original title / Originaltitel Optisch-vestibuläre Interaktion im Wirkungsgefüge der subjektiven Vertikalen
Summary / Zusammenfassung The perception of the vertical is based on sensory information gained from a visually structured environment and from gravitoreceptive information of vestibular origin. The experiments in the human centrifuge aim toward an understanding of the perceptual mechanisms that underlie visual-vestibular interaction. The following parameters are varied:
- Body orientation in three dimensions (yaw, pitch and roll)
- Structure and orientation of visual information
- Magnitude of resultant gravitational force by means of centrifugation (max: 2g)
This allows for further insights into a highly developed information processing system yielding the phenomenal stability of perceptual space. The findings are implemented in system-theoretical models considered in relation to neurophysiological evidence.
