Right-handed sixth graders were administered the WISC Block Design and verbal and nonverbal versions of the Rod-and-Frame Test (RFT), measuring field dependence/independence. Results seemed to reflect a right hemisphere processing for the nonverbal RFT and a possible sex bias against girls in its traditional verbal administration. (Author/SJL)

Designed to investigate the performance of American Indian youth on the "Wechsler Intelligence Scale for Children" (WISC) compared to the "Chicago Non-Verbal" (CNV) for the purpose of establishing validity and reliability of the measurement and appraisal tools, this study analyzed test data from 71 Indian youth (aged 11 to 15)…

The investigation examined the "Wide Range Achievement Test" (WRAT) and its subtests (spelling, reading, and arithmetic), as well as possible differences attributable to the factors of sex, with the "Chicago Non-Verbal" (CNV) as a criterion variable. The 1970 study encompassed 72 Indian students (with a mean chronological age…

The results of this study show that, below ten years of age, stability in IQ scores from group verbal tests is considerably below that for Stanford-Binet. Non-verbal IQ scores were found to have substantially less stability than verbal IQs. (Author/DEP)

The relationship of the Progressive Matrices Test (PM) to the Lorge-Thorndike Intelligence Test (LTIQ) and the Wechsler Intelligence Scale for Children (WISC) is examined. Predictive power of these measures with respect to a number of achievement measures was also investigated. The initial sample consisted of 242 first graders and 281 second…

The stability and change of verbal, non-verbal, and total IQ scores from group tests were investigated for students tested at Grades 1, 2, 4, 7, 9, and 11. Conclusions are discussed in detail, and the following recommendations are made: (1) Group intelligence tests should not be routinely administered in Grades 1 and 2 unless the users and…
