Extract

Problem

Elsewhere (3) it has been argued that, when reporting a subject's results on the WISC (5), it is preferable to give them in the form of scores or intelligence quotients on orthogonal factors than as Verbal and Performance I.Q.s since the latter overlap in a rather arbitrary fashion. In this study a similar recommendation is implied when dealing with a subject's results on the WAIS (6) and the problem is to indicate how factor scores on this test can be obtained.
