The effect of long-term exposure to microgravity on the perception of upright

Sensory perception: Knowing which way is ‘up’ Prolonged exposure to microgravity has a long-term effect on the perception of upright. On earth we use visual, body, and gravity cues to help us determine the orientation of ourselves relative to the world which affects many perceptual tasks including r...
