Design outcomes

Primary

MeasureTime frame
Primary Objective: To explore the effects of different strengths of gravitational stimuli on the perception of "upright" and "vertical" as a function of sex, and thereby improve our understanding of orientation perception in humans.

Secondary

MeasureTime frame
secondary objectives: (a) To explore sex differences in the influence of Earth's constant gravity on the effects of centrifugal force with respect to perception. b) To explore sex differences in the influence of otolith features on the perception of "vertical".
