The Effects of Visual Reference on Adaption to Coriolis Accelerations,
Abstract
Three groups were exposed to stepwise increments of Coriolis accelerations in three visual modes: Internal Visual Reference (IVR), External Visual Reference (EVR), and Vision-Absent (VA). The subjects in the IVR condition required significantly greater amounts of stimulus exposure to neutralise their illusory subjective reactions. They also suffered a greater loss of well-being, and a more marked incidence of motion sickness than did subjects in the EVR and VA conditions. The 30 subjects who completed the first session were exposed to the same graded cross-coupled stimulation one week later. This time, however, all the subjects were retested under the IVR conditions. All three groups showed some positive transfer of adaptation from Session I to Session II, but only the IVR-IVR combination required significantly fewer head motions to achieve the same level of adaptation on the second occasion. Taken overall, however, the most efficient and least distrubing route to adaptation at the completion of Session II was via the VA-IVR combination. (Author)
