SOME FACTORS IN HUMAN VISUAL DISCRIMINATION,
Abstract
The document is concerned with the variables that affect visual function. All are important since they affect the probability that a stimulus will be seen. The variables may be considered in two classes, those that refer to the characteristics of the stimulus and those that refer to the conditions of the observer. Some of them have direct and obvious application to military problems such as in the visibility of radar signals. There are also direct applications to day and night lookout, where background brightness, level of adaptation, and the size and contrast of the target are important. (Author)
