Examines the factor structure of the Wechsler Adult Intelligence Scale-Revised across nine age groups using several methods of factor analysis, including reliable component analysis (RCA). Factor structure is discussed, and the usefulness of the RCA method is demonstrated. (SLD)

Uses the Dumont-Faro short form to estimate the Wechsler Intelligence Scales for Children-III (WISC-III) Full Sale IQ scores for 45 special education students. Results demonstrate that IQ scores were positively correlated with the WISC-III Full Scale scores. However an IQ miscalculation rate of 44% challenges the utility of the Dumont-Faro short…

Evaluates the effects of rater reliability of common IQ and achievement tests on subsequent learning disorder eligibility determinations, particularly with respect to difficulty level of individual subtests and expertise of the scorer. The study corroborates previous findings of strong interrater reliability on most subtests of common IQ and…

Studied the role of response fluency on results of the Raven's Advanced Progressive Matrices (APM) Test by comparing scores on a test of generation speed (speed of generating rules that govern the items) with APM test performance for 127 Belgian undergraduates. Discusses the importance of generation speed in intelligence. (SLD)

Evaluates, with respect to the quality of evidence offered in support of knowledge claims, the relationship between culture and test session behavior (TSB) on group and individual tests of intelligence and/or achievement. Identifies four relevant categories in the literature. Reviews key literature from the speculative theories and studies of…

Examines the concurrent validity of the Slosson Full-Range Intelligence Test (S-FRIT) by comparing S-FRIT scores to the scores of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and the Woodcock-Johnson Tests of Achievement-Revised (WJ-R). Results revealed that the S-FRIT scores were more related to overall intelligence,…

The cube imitation test was developed by Knox (1913) as a nonverbal test of intelligence. Many variants show satisfactory reliability, but performance is correlated both with Verbal IQ and with Performance IQ. Performance is impaired by cerebral lesions but unrelated to the side of lesion. Examinees describe both verbal and visuospatial…

It has been suggested that computer simulations may be used for intelligence assessment. This study investigates what relationships exist between intelligence and computer-simulated tasks that mimic real-world problem-solving behavior, and discusses design requirements that simulations have to meet in order to be suitable for intelligence…

The standardization of the French version of the Wechsler Adult Intelligence Scale (WAIS-III) was conducted after carefully adapting the French version from the U.S. version and extensive field testing. The standardization sample was composed of 1,104 participants from 16 to 89 years. To assess the construct validity of the French version,…

The Test of Nonverbal Intelligence-3rd Edition (TONI-3) and the Analogic Reasoning (AR) subscale of the Universal Nonverbal Intelligence Test (UNIT) were administered to 35 individuals with autism to determine whether real-world-knowledge deficits affected intelligence scores. The 2 tests are similar in format; however, the TONI-3 includes only…

Background: The relationship between adaptive behaviour and cognitive functioning in offenders with intellectual disabilities is not well researched. This study aims to examine gender and age effects on the relationship between these two areas of functioning. Method: The "Vineland Adaptive Behavior Scales" (VABS) and the "Kaufman…

The gains of scores on standardized intelligence tests (i.e., Flynn effect) have been the subject of extensive debate concerning their nature, causes, and implications. The aim of the present study is to investigate whether five intelligence tests are measurement invariant with respect to cohort. Measurement invariance implies that gains over the…

This study tracks intellectually precocious youths (top 1%) over 20 years. Phase 1 (N = 1,243 boys, 732 girls) examines the significance of age 13 ability differences within the top 1% for predicting doctorates, income, patents, and tenure at U.S. universities ranked within the top 50. Phase 2 (N = 323 men, 188 women) evaluates the robustness of…

The relation between intelligence and birth order was shown in a recent publication [Bjerkedal, T., Kristensen, P., Skjeret, G. A. & Brevik, J. I. (2007). Intelligence test scores and birth order among young Norwegian men (conscripts) analyzed within and between families. "Intelligence," 35, 503-514] to be negative. Subjects in this…

In this book, the author describes the complexity of the Self as the source of all human behavior. She will try to outline the structure of the Self, its normal growth and development, and the role of interaction with other living things in this process. Ms. Roeper sees the Self as a unit within us, which includes input from the brain and all…
