To measure the amount of information transmitted by matrices containing dots in various patterns, a 2 × 3 × 2 (subjects × matrices × tilt) randomized groups design with factorial experiment was used. 60 normal subjects and 60 hospitalized schizophrenic patients were tested with 27 matrices in two angular positions. The normal subjects received more information from the stimuli than the schizophrenics. The matrices with horizontal grids transmitted more information than those with no grids or oblique grids. The stimuli without any tilt transmitted more information than the ones with a 45° counterclockwise tilt.
