Veridical perception of the visual world and motor performance which respects the location of objects in space is essential to survival. Mechanisms of some complexity support the development and maintenance of the capacity for perceptual-motor coordination. The evolution of these mechanisms has been accomplished in a terrestrial environment. Thus, it is not surprising that their operation is imperfect in specialized environments as are encountered in high performance aircraft. The altered gravitational-inertial forces encountered in such environments may disturb equilibrium, degrade motor performance and generate visual and postural illusions. Spatially-directed behaviors depend on two broad categories of accomplishments to locate objects through one or more perceptual channels and the ability to monitor ones own position in space. The outcome is the ability to move toward targets either with the whole body or with a part such as head or limb. The visual and vestibular systems as sources of information about the location of objects in space are the primary concern of this report.
