Many Flynn effect (FE) studies compare scores across different editions of Wechsler's IQ tests. When construct changes are introduced by the test developers in the new edition, however, the presumed generational effects are difficult to untangle from changes due to test content. To remove this confound, we use the same edition of Wechsler…

There is significant debate over the value and ethics of IQ testing for children, including those from diverse cultural groups, particularly in light of studies examining performance on various subtests that are uncovering important processing differences between cultural and linguistic groups (Sotelo-Dynega, Ortiz, Flanagan, & Chaplin, 2013).…

This paper presents a systematic review of published data on the performance of sub-Saharan Africans on Raven's Progressive Matrices. The specific goals were to estimate the average level of performance, to study the Flynn Effect in African samples, and to examine the psychometric meaning of Raven's test scores as measures of general intelligence.…

The Wechsler Intelligence Scale for Children (WISC) is the most commonly used intelligence test for children. Five years ago, a Spanish version of the WISC-IV was published (WISC-IV Spanish; Wechsler, 2005), but a limited amount of published information is available regarding its utility when assessing clinical samples. The current study included…

Purpose of the present investigation was to provide further normative data on the D 48 using American college students and to determine the relationship of scores on the D 48 to those on (a) the Otis Mental Ability Test, Gamma Form, AM, and (b) a nonverbal test, Revised Minnesota Paper Form Board.

Compared regression lines for prediction of Wide Range Achievement Test scores by Wechsler Intelligence Scale for Children and revised WISC Full Scale IQs across race. Results support the use of a common regression line in the prediction of achievement scores for races. (Author)

Results offer empirical support to Ilg and Ames's claim that the Gesell battery is an excellent predictor of school readiness. The close similarity of the Piaget and Gesell tests accords well with previous findings that the two tests have much in common. (Authors/MB)

The mean IQ on the Slosson Intelligence Test (SIT) was substantially higher than expected based on the earlier Peabody Picture Vocabulary Test (PPVT) scores. Sampling error and examiner error were excluded as explanations. Results suggest that the PPVT and SIT yield different scores and lack comparability. (Author)

The SIT Correlates highly enough with ACT scores to be considered a valid instrument for predicting acceptance and success in college. (Authors)

The purpose of this paper was to evaluate the comparative validity of the Information and Vocabulary subtests of the Wechsler Adult Intelligence Scale (WAIS), the WAIS Verbal and Full Scale Intelligence Quotients, the verbal scores of several standardized scholastic aptitude tests, and their corresponding composite scores relative to a college…

Validity of the Cognitive Levels Test (CLT) was evaluated by correlating test scores of 48 gifted 10-year-olds with scores on the Stanford-Binet intelligence scale as preschoolers as well as with scores from the California Achievement Test. Results indicated high degrees of CLT validity in both measuring cognitive ability and predicting academic…

WISC-R (Wechsler Intelligence Scale in Children-Revised) Verbal and Performance scores were correlated with WRAT-R Wide Range Achievement Test-Revised scores. The verbal score was found to predict reading, spelling, and arithmetic. The performance score did not add significantly to the predictions. Results were consistent with earlier studies.…

Administered System of Multicultural Pluralistic Assessment (SOMPA) to 700 White, 700 Black, and 700 Hispanic elementary school students. Ten years later, again tested 1,184 of original 2,100 students with SOMPA in high school. Results suggest that some subtests of the SOMPA may have some validity for predicting school achievement for students…
