Construction of simple vectographic slides for Ver stimuli.
A series of 35-mm vectographic checkerboard slides has been developed which, when projected through a rotating polaroid analyzer, generate an oscillating checkerboard for use as a stimulus in visual evoked response (VER) experiments. Sample VER data are presented from a 4-year-old and a 23-year-old subject, using a variety of check sizes and using a color-sound cartoon superimposed over the checkerboard to encourage attention. These slides provide a simple yet versatile means for producing VER data.
