This study attempts to compare the blocking of the Berger rhythm caused by visual and auditory sensations. Four stimuli were used - a bright light of one hundred (100) watts, a dim light of twenty-five (25) watts, a thousand cycle tone at approximately seventy (70) decibels, and a similar tone at approximately forty (40) decibels. A series of two hundred stimuli composed of fifty of each of these arranged in random order was presented to the subject. The records were read for latency and perseveration of the blocking and the four types of stimulus were compared.
