This study concerns the manner in which the accuracy of quantitative scale readings varies as a function of illumination and acceleration. The following basic findings resulted from an analysis of the data from this experiment: 1. At the higher levels of instrument illumination, increasing acceleration and decreasing luminance produce relatively small increase in reading errors. 2. At marginal levels of illumination, acceleration and luminance interact to produce a relatively large increase in error. 3. Intensity of illumination can compensate for the decline in visual performance at stress levels above 1 g.

"This report is a review and evaluation of research pertaining to the effects of acceleration on human vision. Studies of gross qualitative changes in vision such as "blackout" and loss of peripheral vision in headward (positive) acceleration and the less dramatic effects in other body orientations to the acceleration vector are discussed first, together with the physiological basis of these symptoms. Then the quantitative and analytic studies of the influence of acceleration on vision are reviewed including the use of electrophysiological techniques and the application of the threshold method of psychophics. Finally a number of areas are pointed out where there is a need for more investigation."--Abstract.
