Verticality Perception Assessed by the Haptic Vertical

NCT02980432 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 19

No results posted yet for this study

Summary

The investigators previously shown that a rotating optokinetic stimulus results in shifts of the subjective visual vertical in healthy human subjects. However, the origin of these shifts is still poorly understood. Both torsional displacement of the eyes and a shift in the internal estimate of direction of gravity have been proposed as potential explanations. Here the investigators use a vision-independent setup to differentiate between these two hypotheses, predicting no impact of a rotating stimulus on the subjective haptic vertical if torsion triggers the shift.

Conditions

  • Healthy

Interventions

OTHER

changes in whole-body roll position and visual/haptic stimuli presented

In different whole-body roll positions subjects will be presented a luminous line or a rod in combination with a moving or stationary background. Participants will be asked to align the line or the rod along perceived direction of gravity.
