The validity of Wechsler's (1949) comments concerning the addition of the supplementary WISC subtests was investigated for a sample of 20 fifth-grade students. The study was designed to investigate whether or not the addition of one or both of the supplementary WISC sub-tests, Digit Span and Mazes, affected obtained IQs of high achieving…

Predicts that by the year 2000, IQ tests will have disappeared, being replaced by evaluations of a broad range of talents and abilities that avoid unfair and damaging labels. (DW)

Subjects included 64 children aged 6-16, who had been administered the WISC-R during prior evaluations. These students had been referred because of academic difficulties. One-third of the sample had taken the test…

This is the latest in a series of reported findings for a Guidance Study which followed the same persons from infancy to age 40. The report focuses on: (1) how well the 50 men and 60 women subjects maintained their positions relative to I.Q. during the 22 years since they were last tested at age 18; (2) gains and losses in I.Q. over the 22 year…

This paper summarizes data comparing the correlation patterns of psychometric, social, and demographic variables with intelligence quotient (IQ) and learning potential (LP) scores derived from the Kohs Block Designs and Raven Progressive Matrices procedures. The sample consists of educable mentally retarded special class and institutionalized…

A study demonstrated the feasibility, reliability and validity of a computer-administered intelligence test. The computer-based test (Slosson Intelligence Test) was compared with a conventional examiner-administered test given to the same college students within the same week. In addition it was evaluated as a predictor of college grade point…

Estimates were obtained of the effects of ethnic group, sex, education, and clinical diagnosis on WAIS IQ scores of psychiatric patients. Expected IQ scores for segments of the general population were calculated by adding or subtracting these effects from an expected IQ for a White high school graduate. (Author/SJL)

An estimated ITPA Psychological Quotient (PQ) was compared to the WISC-R Verbal, Performance, and Full Scale IQs of developmentally disabled children, ages 6 to 13. The PQ related strongly to Verbal and Full Scale IQs. Implications for diagnosis and screening are discussed. (Author/SJL)

Intercorrelations among the Metropolitan Achievement Test (social studies) and three cognitive abilities tests (verbal, quantitative, and nonverbal) were calculated for a sample of fifth grade pupils. (JKS)

Discussed is the 1977-78 trial involving the California state superintendent of public instruction and a Black child, allegedly misplaced in EMR classes on the basis of IQ tests. (JLH)

This study examined whether a timesharing factor can be identified when a number of competing tasks are presented in the midst of a range of single tests designed to sample a broad range of psychological dimensions.
