Mackintosh and Bennett [Mackintosh, N. J., Bennett, E. S. (2005). What do Raven's Matrices measure? An analysis in terms of sex differences. "Intelligence, 33," 663-674] reported that male students obtained higher scores than females on Raven's items that required for their solution addition/subtraction or distribution of two rules, but…

The S.I.T. is an age scale of intelligence with demonstrated reliability and high validity coefficients correlated to the Stanford-Binet. The items of the SIT were classified according to a scheme resembling Valett's classification of Stanford-Binet test items. A comparison of the classifications is made. (Author)

Retired vice-president of Educational Testing Service asserts that chances for tests being misused are greater than ever. Speech delivered at ETS's Invitational Conference on Testing Problems on October 28, 1972, in New York, New York. (DS)

Tables permitting the conversion of short-form composite scores to full-scale IQ estimates have been published for previous editions of the Wechsler Adult Intelligence Scale (WAIS). Equivalent tables are now needed for selected subtests of the WAIS-III. This article used Tellegen and Briggs's formulae to convert the sum of scaled scores for four…

Several studies concerning scoring difficulties on the Wechsler intelligence scales were reviewed. Since scoring of responses on the comprehension, similarities and vocabulary subtests of the Wechsler scales demands judgements by the examiner, the possibility of poor interscorer reliability increases. More thorough scoring standards and revision…

Discusses four ubiquitous major sources of measurement error for individual intelligence scales. Argues that where these sources cannot be directly investigated, they should be estimated rather than ignored. Estimated the typical magnitude of error arising from each of content sampling, time sampling, scoring, and administration. (Author)

This study investigated patterns of Wechsler Intelligence Scale for Children (WISC) Third Edition subtest scores for 42 gifted children in grades 4-8. Variability from subtest means was highest on Similarities, Comprehension, Coding, and Symbol Search subtests. Significant weaknesses were found on the Block Design subtest, seen as a peak subtest…

The question of reliability in the intellectual assessment of young children is cause for concern among developmental psychologists and diagnosticians. The issue of reliability is confounded by normal variability in skills during early childhood, by the problem of consistency across time of age-appropriate assessment measures, and by the selection…

Argues that the typical psychometric model of human intelligence is limited because the database fails to take account of the many manifestations of intelligent behavior that are displayed in the world outside the testing room. Suggests that cognitive processes are influenced by test situation or setting and examiner's level of expertise. (PS)

An application of the two-paramenter logistic (Rasch) model to tailored testing is presented. The model is discussed along with the maximum likelihood estimation of the ability parameters given the response pattern and easiness parameter estimates for the items. The technique has been programmed for use with an interactive computer terminal. Use…

This fact sheet lists problems involved in the use of standardized tests. It is argued that standardized tests are not really fair and helpful evaluation tools because they reward the ability to answer superficial questions quickly and do not measure the ability to think or create in any field. They also assume that all test takers have been…

The use of the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) and its interpretation in educational use are discussed. To measure intelligence, Wechsler believed one must measure the various aptitudes that contribute to the total behavior of the individual. The WISC-III has six verbal subtests and seven performance subtests.…
