Abstract : The purpose o the study was to measure the accuracy with which subjects perceived horizontal arrays of black and white figures, and to analyze the determinants of this accuracy. Two groups of subjects were shown arrays of black and white figures under conditions of brief exposure. Accuracy of the perception of these arrays was demonstrated to be a function of the number of runs (homogeneous color units) in the array. Further analysis of the determinants of accuracy furnished the basis for a tentative model of the mechanism used in perceiving the arrays. On the basis of variables associated with this mechanism, between 63% and 73% of the variance in array difficulty can be accounted for.
