This paper reports primarily the use of the MWLT (Walton and Black, 1957) on aged subjects with a variety of clinical conditions. Earlier studies by Walton (1958), Walton, White, Black and Young (1959) and Walton and Mather (1961) demonstrated that the MWLT identified over 80 per cent. of organics without any misclassification of non-organics. More recently, Orme, Lee and Smith (1964) found that 81 per cent. of organics were correctly classified, but only 69 per cent. of non-organics. Misclassification was particularly serious with schizophrenics (70 per cent.). Other reports, including Newcombe and Steinberg (1964), White and Knox (1965), have found as few as 47 per cent. of the organic group correctly classified. These recent studies cast some doubt upon the original claims of the MWLT as a diagnostic test of generalized brain damage. We hope to present further evidence on the efficiency of the MWLT; particularly on its use with elderly subjects.
