Abstract

The results of J. P. Guilford's card-sorting experiment by the method of equal appearing intervals are analyzed mathematically. The constants of the psychometric functions are obtained by processes analogous to the constant process. When these constants are determined (a) independent of the supposition that the series of groups into which the cards were sorted is quantitative in character and (b) under this supposition, good agreement is found between them. Guilford's results agree with Weber's and Fechner's laws in both cases.
