Intelligence has been extensively explored across various disciplines such as psychology, cognitive science, and neurology. Countless scholars have delved into understanding why certain individuals exhibit higher mental acuity and knowledge. Consequently, numerous studies aim to unveil the essence of intelligence and gauge human cognitive…

Within a population-based study of 3356 children, we investigated whether infant neuromotor development was associated with cognition in early childhood. Neuromotor development was examined with an adapted version of Touwen's Neurodevelopmental Examination between 9 and 20 weeks. Parents rated their children's executive functioning at 4 years. At…

Every widely used psychological assessment instrument is under scrutiny in terms of cultural fairness. The expectation of the reduced-language (Nonverbal) section of the Stanford-Binet Intelligence Scales, Fifth Edition (SB5; Roid, 2003) is that language ought not to be a modifying factor in terms of final score. The purpose of the present study…

Arguments requiring separate deaf norms are evaluated with data describing deaf and hearing children's performances on nonverbal intelligence tests. The issue of which norms a psychologist should select for scoring Wechsler Intelligence Scale for Children (Revised) Performance Scale protocols is discussed with reference to the impact that deaf and…

Applied reliable component analysis (RCA) to the normative data (2,100 children and adolescents) for the Universal Nonverbal Intelligence Test (UNIT) (A. Bracken and R. McCallum, 1998) to allow for the computation of reliable uncorrelated memory and reasoning scores. RCA sores were highly replicable, had good convergent validity, and had greater…

Results of the Test of Nonverbal Intelligence (TONI), Wechsler Intelligence Scale for Children-Revised (WISC-R), and Wide Range Achievement Test were compared for 66 learning disabled children in grades one through six. The TONI mean score was found to be significantly different from the WISC-R Performance Intelligence Quotient (IQ). Implications…

To study the applicability of the Kaufman Assessment Battery for Children (K-ABC) for assessing hearing-impaired children, nine hearing-impaired children (ranging in age from 6 years 4 months to 11 years 10 months) were administered the battery. Hearing losses for the nine children ranged from moderate to profound. During the evaluation of seven…

Administration of nonverbal IQ tests to 12 children with normal language and 12 with language impairments (ages 8-10) revealed that the children with language impairments had lower scores than controls, and that nonlinguistic deficits of children with language impairments adversely affected their responses to specific types of items on nonverbal…

Validity studies conducted with the Stanford Binet Intelligence Scale: Fourth Edition (SB:FE) are reviewed. Results support its validity as a measure of general mental ability and that it can distinguish between groups of youngsters with differing intellectual abilities. Recommendations are made for use of the SB:FE. (SLD)

Performance was better for children above six years of age and better in Spanish than English. It is suggested that the Peabody Picture Vocabulary Test never be used to assess the general intelligence of Mexican American children, because it likely underestimates their ability. (Author)

The relationship between scores on Raven's Coloured Progressive Matrices (CPM) scores and subtest scores and IQs from the Wechsler Intelligence Scale for Children-III (WISC-III) was studied for 28 children aged 6 to 11 years. Subjects had been referred to a university assessment center because they were believed to have exceptional learning…

This article describes the Comprehensive Test of Nonverbal Intelligence, an assessment designed to evaluate the intellectual ability of students ages 6 to 18.11 years for whom other mental ability tests are inappropriate or to enable comparisons between verbal and nonverbal intellectual ability. Its administration, standardization, reliability,…
