MULTI-FIELD ELECTRONIC APPARATUS FOR STUDIES OF VISUAL PERCEPTION
Abstract
An apparatus is described that precisely controls intensity, duration, and order of firing of gas-discharge lamps. It can be used to illuminate visual stimulus objects for either long or short exposures, and in different viewing modes. Various methods of reducing the onset variability usually encountered with gasdischarge lamps also are described. Although designed primarily for the study of contour formation and visual masking, the apparatus can be used wherever a controlled sequence of separate stimulus presentations is required, as in studies of apparent movement, critical flicker frequencies, and time-dependent series.
