Abstract
Abstract.— Scoring only the unsigned (absolute) errors in the Rod‐and‐Frame Test (RFT) is questioned because the method confounds a number of variables. Another way of scoring the RFT is proposed which differentiates between (1) the subject's constant error, (2) the effect of the tilted frame, and (3) the rod starting position effect. The method also allows estimation of the response consistency of the subject. What is more, the values for each subject of the constant error, of the frame tilt effect, and of the rod starting position effect may be tested for significance on the basis of the degree of response consistency observed for that particular subject, thus making the new method more person‐oriented than the unsigned error method.
