Four of the subtests of the Williams Scale for the Measurement of Memory were examined with the object of establishing the equivalence of the three forms of the scale, the reliability of each subtest, the effects of age and intelligence on three of them, their independence of each other, and their validity in relation to ( a ) EEG tracings, and ( b ) two other psychological tests of memory disorder. The results suggest that the test of delayed recall and the word‐learning test would be worth developing further in the clinical examination of dementia. A verdict on the value of the Rey‐Davis test of non‐verbal learning in the investigation of cerebral pathology must await the outcome of further research experience with this test.
