Presents a study of the development of conservation of weight among socially deviant adolescents. (BD)

The response of mentally retarded children to various stimuli (low active remain low active, high active remain high active) relates activity to intelligence and suggests that, for low intellectual functioning subjects, the retardation was due to endogenous reasons with consequent organic brain involvement affecting mechanisms controlling activity…

This research attempts to determine the usefulness of assessing academic achievement motivation, biographical information, and parental perceptions in the prediction of academic achievement and reading efficiency. The Iowa Test of Basic Skills (ITBS) and the Lorge-Thorndike IQ test provided data for criterion measures of educational achievement…

The author discusses general principles, rationale, and methods used in the training of graduate students in general intelligence testing instruments at the University of Calgary. (MB)

The author argues that by ignoring evolutionary considerations, the intelligence testing movement has precluded continued development, and in order to regain momentum it must engage in theoretical and empirical research to accommodate those considerations. (MB)

Reviewed in the paper are theories and concepts about intelligence, and proposed is a theory set forth in stimulus-response terminology. Available from: Ablex Publishing Corporation, 355 Chestnut Street, Norwood, New Jersey 07648. (CL)

Home environments of 91 6-month-old infants were assessed with the Home Observation for Measurement of the Environment Inventory to predict whether a child would be low IQ (below 70), low average (70 to 89), or average to superior (90 and above) at age 3 years. (Author)

Investigated geographic differences in Wechsler Adult Intelligence Scale (WAIS) results by comparing 60 Hawaiian and 60 mainland United States psychiatric outpatients. The influence of pidgin English led to expectations that Hawaiian subjects would have significantly lower WAIS Verbal scores than mainland subjects. Data verified these…

Forty-four educable mentally retarded students (12-16 years old) were given the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Wechsler Intelligence Scale for Children (WISC). (CL)

The hypothesis that fluid intelligence is equivalent to the factor of general intelligence is investigated using LISREL to specify higher-order models in reanalyses of three sets of psychometric data from subjects 11, 13, and 15 years old. The three studies showed fluid intelligence to be equivalent with a general factor. (LMO)

Results of the study with 24 mildly or moderately retarded subjects (ages 11-55 years) indicates that a separability hypothesis of perceptual development can be extended to retarded populations. Representation as wholistic objects dominated among moderately retarded subjects, and with increasing intelligence, representation of objects as component…

Examined concurrent validity of Stanford-Binet Intelligence Scale, 4th edition (SB IV) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) in a homogeneous, nonexceptional sample of 32 early elementary school children. Findings suggest that SB IV has significant positive relationship with WISC-R. The tests displayed a moderate level…
