Samples in research on individual and group differences may be selected based on whole scores which differ from the population mean. Children are diagnosed in clinical practice with a whole score. These procedures produce regression to the population mean which can affect accuracy and adequacy of part score interpretations. (Author/DWH)

This study examined differences between Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 40 elementary students with learning disabilities. WISC-III Full Scale, Verbal, and Performance scores were lower than comparable WISC-R scores by one-third to one-half a…

This study determined the degree to which the Non-Language Test of Verbal Intelligence, developed to measure verbal ability through a nonlanguage medium, could measure verbal intelligence. Correlation with the Differential Aptitude Test-Verbal suggested the existence of some common, as well as some uncommon, factors between the two tests.…

Three conditions for administering creativity tests by Torrance and by Wallach and Kogan were compared: (1) untimed, gamelike; (2) conventional testlike; and (3) administration of measures under testlike conditions on two adjacent days, using the second testing as the predictor. The conventional testlike condition seems optimal. (Author/CP)

To find the concurrent validity of two scholastic aptitude tests when a scholastic achievement test was used as a criterion for use in placement of mentally retarded children, 127 subjects were involved. The California Achievement Test (CAT) was used as a criterion measure, and the Primary Mental Abilities test (PMA) and the Slosson Intelligence…

A study was conducted at Cuyahoga Community College to test the relationship between student scores on timed and untimed reading comprehension and vocabulary tests, and to investigate the relationship between those scores and intelligence. The study sample included 72 students enrolled in classes at developmental, freshman, and sophomore levels.…

To examine the validity of short forms of the Wechsler Intelligence Scale for Children-Revised (WISC-R), the WISC-R was first administered to 106 hospitalized psychiatric patients, aged 8-16. No subjects had a primary diagnosis of mental retardation or learning disability, and one-third were receiving psychotropic medication. WISC-R IQ scores…

Chicano and Amerindian vocabulary scale responses from the Stanford-Binet (LM) and Wechsler Intelligence Scale for Children were item-analyzed for 1,009 subjects. The response patterns differed both by ethnic group and test, as well as by age. The most common, and recurring, pattern found was "level-of-difficulty" gradient…

The stability and change of verbal, non-verbal, and total IQ scores from group tests were investigated for students tested at Grades 1, 2, 4, 7, 9, and 11. Conclusions are discussed in detail, and the following recommendations are made: (1) Group intelligence tests should not be routinely administered in Grades 1 and 2 unless the users and…
