This report attempts to consolidate the findings of previous research in the area of acceleration effects upon performance and to relate these findings to basic piloting behaviors. The decrements in the visual, psychomotor response and intellectual processes which have been found to accompany acceleration stress are quantified where possible. Both transverse and positive accelerations have been shown to raise the level of contrast required for visual brightness and to reduce general acuity at accelerations well below those which result in gross visual impairment. Similar impairments in discrimination response rates are also discussed. The techniques thus far used to assess higher mental ability under acceleration are presented as are some of the problems which complicate such measurements. Data from such studies are presented to illustrate the reduction in immediate memory and information processing capabilities of pilots experiencing both high level, short term and moderate, extended accelerations.
