This study investigates Verbal, Performance, and Full Scale IQ change in an institutionalized mentally retarded population. 402 individuals who had received two routine administrations of either the Wechsler Intelligence Scale for Children or the Wechsler Adult Intelligence Scale and who ranged in age from 11 to 44 were included as subjects. They were divided into six groups (two WISC and four WAIS) and changes in scores were studied using a semi-longitudinal methodology. Contrary to the dominant view suggested by previous research, Full Scale IQ did not decrease with age. There were, in fact, slight increments, larger and more consistent in Performance than Verbal IQ. This differential change is discussed in terms of the Horn-Cattell theory of “fluid” and “crystallized” intelligence.

The WAIS, the original edition of the Ohio Literacy Test, and its auditory form were administered to 60 male psychiatric inpatients at the time of hospital admission. Correlations were .54 to .70. Tentative results suggest that this auditory form may have some merit as a quick estimator of WAIS Full Scale IQs.

SummaryIn relation to two measures of the mobility involved in the migration histories of individuals now resident in the Otmoor villages of Oxfordshire, selectivity for components of the Wechsler Adult Intelligence Scale is clearly demonstrated. However, this selectivity is reconsidered in the light of other covariates of mobility, where these also relate to IQ, for example, some measures of temporal and socioeconomic variation. When correction is made for these, the frequency of highly significant correlations is greatly reduced, suggesting that much of the selectivity operates within the associations between mobility, IQ, and the confounding temporal and socioeconomic variables. There remains, even after removal of the effects of age, class and occupation-type, a pattern of significant association between some components of verbal IQ and the measures of mobility.

The Kaufman Brief Intelligence Test detects learning problems of young students and is a screen for whether a more comprehensive test of intelligence is needed. A study to assess whether this test was valid as an adult intelligence test was conducted with 20 undergraduate psychology majors. The correlations between the Kaufman Brief Intelligence Test's Composite, Vocabulary, and Matrices test scores and their corresponding Wechsler Adult Intelligence Scale-Third Edition test scores, the Full Scale ( r = .88), Verbal ( r = .77), and Performance scores ( r = .87), indicated very strong relationships. In addition, no significant differences were obtained between the Composite, Vocabulary, and Matrices means of the Kaufman Brief Intelligence Test and the Full Scale, Verbal, and Performance means of the WAIS–III. The Kaufman Brief Intelligence Test appears to be a valid test of intelligence for adults.

A woman was admitted to a psychiatric hospital. Feeling increasingly depressed she had made a suicidal attempt. Besides somatic complaints, she related friction with her husband. The latter reported her as being inadequate at coping with their children, with general domestic chores or with entertaining his business friends. The woman's full scale I.Q. on the Wechsler Adult Intelligence Scale was found to be 73, in the borderline subnormal range.
