In a previous experiment the author investigated the influence of color on reactions to ink blots by a technique in which two independent groups of subjects were presented matched chromatic and achromatic blots. This technique was used to demonstrate that when the color variable is completely isolated it has measurable effects, which show up as group differences or trends in both the reaction time and the content of the conceptual responses. But such a technique employing independent groups for chromatic and achromatic blots has serious limitations from the point of view of providing a solution to the major experimental and clinical problems in this area. From the standpoint of experimental design, a technique based upon independent groups can yield measures only of group trends, it cannot provide a valid method of measuring the effect of a given variable upon a particular individual's reactions. Measurement of the specific effect of a variable, like color, upon particular individuals is strictly possible only if each subject serves as his own control; comparable chromatic and achromatic data for each subject must be provided.
