Charles Spearman and L. L. Thurstone were pioneers in the field of intelligence. They not only developed methods to assess and understand intelligence, but also developed theories about its structure and function. Methodologically, their approaches were not that distinct, but their theories of intelligence were philosophically very different --…

The practice of individual assessment has been moving toward the empirically derived Cattell-Horn-Carroll (CHC) theory of intellectual ability, which offers a hierarchical taxonomy of cognitive abilities. Current assessment tools provide varying adherence to operationalizing CHC theory, making clinical inference difficult. Expert consensus…

According to J. B. Carroll's (1993) 3-stratum theory, performance on any subtest reflects a mixture of both 2nd-order and 1st-order factors. To disentangle these influences, variance explained by the general factor should be extracted first. The 1st-order factors are then residualized, leaving them orthogonal to the general factor and each other.…

Addresses the question of abnormality when comparing a subject's score on each subtest with that subject's average subtest score on one of Weschler's scales. Suggests comparing each subtest score with the Verbal or Performance average rather than with the overall average. Provides tables estimating differences of standardization samples. (BH)

Word concepts have long been recognized as an integral part of intelligence, and word definition tasks are frequently used to measure them. Entire subtests requiring definitions, usually called vocabulary tests, are common; because of their apparent stability and comparability with overall intelligence, these subtests have been given a preeminent…

The theoretical background, organization, performance subtests (object assembly, geometric design, block design, mazes, picture completion, and animal pegs), verbal subtests (information, comprehension, arithmetic, vocabulary, similarities, and sentences), reliability, validity (factor analysis), interpretation, advantages, and limitations of the…

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,…

This article describes the Kaufman Brief Intelligence Test, an assessment of intelligence for individuals ages 4 to 90. The test is designed for those circumstances in which a brief measure of intelligence will suffice and trained professionals may be unavailable for the assessments. Its administration, reliability, and validity are discussed.…
