ABSTRACT When the eye is stimulated with an intermittently illuminated area bordered by a dark surround, the portions of the area adjoining the border will take on a greater apparent brightness than the remaining area. This region of enhanced brightness resembles nothing as much as a halo extending from the border into the field. This study is a preliminary investigation of how this perceived halo varies with the intermittence rate, the pulse duration, and the pulse luminance. The spatial characteristics of the border enhancement halo were found to be closely related to these stimulus parameters.
Arnulf Remole (Thu,) studied this question.
