Document Summary
Canadian space psychology is a rapidly developing area of research and includes examination of such matters as the effects of isolated and extreme environments and the nature of effects of multicultural interactions. Astronauts in space experience a reduction in their hand-eye coordination. While on earth, gravity provides important cues for people"s judgement concerning the spatial orientation of their bodies. In space however, astronauts can"t depend on gravity as a cue -- they lose sense of what is up and what is down. This can lead to disorientation, difficulty in task performance and motion sickness. There may be discontinuity between sensory information derived from the vestibular system (organs in the inner ear) and visual cues. Ordinarily, people can rely on three types of cues to determine which way is up; visual, gravity and body direction. In space, astronauts are primarily dependent on visual cues as they found that body orientation cannot help establish the direction of up.
