Results of five studies show that during the second half of the twentieth century there were increases in the Development Quotients (DQs) of infants in the first two years of life. These gains were obtained for the Bayley Scales in the United States and Australia, and for the Griffiths Test in Britain. The average of 19 data points is a DQ gain of…

In this study, the authors used structural equation modeling to investigate relationships between ability constructs from the "Wechsler Intelligence Scale for Children-Third Edition" (WISC-III; Wechsler, 1991) in explaining reading and mathematics achievement constructs on the "Wechsler Individual Achievement Test" (WIAT;…

Effects of assignment to a regular classroom, to a resource room, or to a remedial reading group were examined in a study of gains in reading achievement of 49 elementary school boys. Measures used included the Slosson Intelligence Test, the Wechsler Intelligence Scale for Children, the Primary Mental Abilities Vocabulary subtest, and the…

The present study examined the factor structure of the Wechsler Intelligence Scale for Children-Fourth Edition, Spanish (WISC-IV Spanish, Wechsler, 2005a) with normative sample participants aged 6-16 years (N = 500) using confirmatory factor analytic techniques not reported in the WISC-IV Spanish Manual (Wechsler, 2005b).

The author reviews and expands the work of J. Boyd (EC 062 111) on the use of the Slosson Intelligence Test scored according to Wechsler Intelligence Scale for Children categories for children who may need special education. (CL)

This study explored relationships between intelligence and visual motor ability and patterns of impairment of visual motor ability in children prenatally affected by alcohol. Fourteen children (mean age 8.2 years) diagnosed with fetal alcohol syndrome (FAS) and 50 children with possible fetal alcohol effects (FAE) were assessed with the Bender…

C. Shedd's hypothesis that hyperactive children would attain highest IQs on a picture vocabulary test, followed by the Wechsler Intelligence Scale for Children (WISC), and a drawing test, was confirmed in a study involving 62 overactive children (8-13 years old). (CL)

This article provides guidelines for an entry-level course that prepares psychology students and practitioners to acquire entry-level skills, abilities, knowledge, and attitudes important to the individual assessment of intellectual abilities of children and youth. The article reviews prominent international, regional, and national policies,…

Comprehensive, individual intelligence tests can be invaluable when used as part of a multi-faceted approach to identify gifted and twice exceptional children. The Wechsler Intelligence Scale for Children (WISC) is a popular cognitive assessment for this purpose. This statement addresses guidelines for use of the WISC-V in the assessment of gifted…

The fourth edition of the Wechsler Adult Intelligence Scale (WAIS-IV) has been used extensively for assessing adult intelligence. This study uses Mokken scale analysis to investigate the psychometric proprieties of WAIS-IV subtests adapted for the Egyptian population in a sample of 250 adults between 18 and 25 years of age. The monotone…

An area of particular importance when examining index scores on the Wechsler Intelligence Scale for Children--Fifth Edition (WISC-V) is the utilization and interpretation of critical values and base rates associated with differences between an individual's subtest scaled score and the individual's mean scaled score for an index. For the WISC-V,…

The study examined the effects of "Process Assessment of the Learner" ("PAL"), a writing expression curriculum. The program was tested with second-grade students in a suburban-rural school district in the southeastern United States. Three sections of PAL lessons were implemented in the district as a small-group curriculum…

The history of cognitive assessment in Brazil is described through evolutionary movements or waves, when tests were just imported and translated from other countries, criticized, and later evaluated in laboratories on test construction founded at private and state universities. The presence of high standards for test use place Brazil at the…

Compared the Cognitive Levels Test (CLT) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 55 children who were referred for remedial educational services. A comparison of the correlations for each of the criterion measures from the WISC-R showed a consistent significant positive relationship with the CLT. (Author/LLL)
