To check on the usual procedure for determining color and shading shock the writer totals the full card response times for the color cards eliciting responses and divides this sum by the total number of responses given by the subject for all of the color cards. The resulting quotient is the average time consumed by the subject for giving a response for the color cards. The same computations are made for the noncolor cards.
