Flynn wrote a book devoted to the Flynn effect, featuring his theoretical explanation of why the intelligence of worldwide populations has apparently increased from generation to generation. The essence of his theorizing is that because of the societal impact of scientific technology, people of today are much more guided by abstract, rather than…

The field of intelligence testing has been revolutionized by Alan S. Kaufman. He developed the Wechsler Intelligence Scale for Children-Revised (WISC-R) with David Wechsler, and his best-selling book, Intelligent Testing with the WISC-R, introduced the phrase "intelligent testing." Kaufman, with his wife, Nadeen, then created his own…

Study compares Wechsler (WISC-R) profiles of special-education students to seven core types distinguished primarily by levels of global ability. More than 96% of these students were found to be similar to one of the core types considered to be common variants of normal intellectual ability. Based on data, it is recommended that "no way"…

Argues that the apparent lack of empirical support for the practice of profile analysis has stemmed in part from the use of statistical techniques that have neglected to explore the perspective of the clinician. Explores Configural Frequency Analysis, a statistical technique focusing on the relationships among groups of participants as the unit of…

Investigated the overlap between the Wechsler Intelligence Scale for Children - Revised (WISC-R) and the Halstead-Reitan Neuropsychological Battery (HRNB) in light of their use in diagnosing children's learning problems using scores for children (N=1,181) on the WISC-R and the HRNB. Results showed primary overlap between measures was attributed to…

Tested one-, two-, three-, and four-factor models within normal and psychiatric adolescent inpatient groups to confirm the factor structure for the Wechsler Intelligence Scale for Children-Revised (WISC-R). For both samples, the Kaufman three-factor solution had the best overall fit of the WISC-R subtest covariance structure. Other models were…

Reports on empirical studies that assessed continuing claims for utility of subtest analysis. Hierarchical regression and discriminate models were used to determine maximum potential of ability subtests to explain variation in academic achievement, stylistic classroom learning, and test-session behavior. Ipsative subtest scores provide no…

Compares various base-rate procedures with statistical-significance testing approach used by psychologists. Nonlinear multivariate method is used to determine whether children with a learning disability or emotional disturbance are more likely to show unusual subtest patterns than are children from the normative sample of Wechsler Intelligence…

To test the validity of the Wechsler Intelligence Scale for Children-Revised (WISC-R) for minority groups, factorial similarity across race was investigated with separate principal-factor analyses for White and Black children from the nationally representative WISC-R standardization sample. On every measure, the White and Black groups were highly…

In spite of massive research efforts, no clear conclusions have been reached with regard to whether specific exceptional groups demonstrate Wechsler Intelligence Scale for Children-Revised (WISC-R) profiles that reliably differentiate them from normative or other exceptional groups. This study applied multivariate clustering and profile analysis…

This study examined agreement rates between identified strengths and weaknesses in shared abilities and influences on the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Kaufman Assessment Battery for Children (K-ABC). Sixty-seven students in the first through seventh grades referred for learning disabilities (LD) evaluation were…
