On the basis of several reviews of the literature, Lynn [Lynn, R., (2006). Race differences in intelligence: An evolutionary analysis. Augusta, GA: Washington Summit Publishers.] and Lynn and Vanhanen [Lynn, R., & Vanhanen, T., (2006). IQ and global inequality. Augusta, GA: Washington Summit Publishers.] concluded that the average IQ of the…

Background: Previous research with earlier versions of the WISC and WAIS has demonstrated that when administered to people who have intellectual disabilities, the WAIS produced higher IQ scores than the WISC. The aim of this study was to examine whether these differences still exist. A comparison of the Wechsler Adult Intelligence Scale-Third…

Administered the WISC and WISC-R to 20 White children and compared their differences in a counterbalanced design to equivalent data obtained from Black children. For the White subjects, no differences were found between WISC and WISC-R measures. Black children scored significantly lower on the WISC-R on all three IQ measures. (Author)

The efficacy of use of the Raven Progressive Matrices Test (RPM) in the selection of gifted children from traditionally underrepresented groups was investigated in a large-scale study with a diverse population. A total of 16,985 subjects were given the Raven Progressive Matrices Test. These included 22.7 percent Latinos, 37 percent Whites, 14…

Administered the WISC and the WISC-R in a counterbalanced design to 20 Hispanic children. Revealed the WISC-R to be as culturally biased as the WISC and that more Hispanic children may be labeled as mentally deficient. Suggested that verbal IQ reflects the extent of acculturation, while Performance IQ reflects actual ability. (Author)

Seeking to compare the original Wechler Intelligence Scale (WISC) with its revised version, the WISC-R, this study compared WISC-R scores of 50 Black children with their WISC scores taken two years previously. Mean scores on the WISC-R were lower on the Verbal Scale, Performance Scale, and Full Scale. (DS)

Experiments demonstrate that in bilingual subjects, Welsh digits take longer to articulate than their English equivalents, explaining why norms for Welsh children on the digit span test of the Welsh Children's Intelligence Scale are less than those for the same age American children. (Author/KC)

Evaluated the test bias of the Verbal IQ as measured by the Wechsler Intelligence Scale for Children-Revised in relation to predictions of academic achievement in two different socioeconomic status groups. Results indicated that Verbal IQs are not biased with respect to socioeconomic status. (Author)

Investigated cultural bias in 79 items of three verbal tests of the Wechsler Intelligence Scale for Children-Revised (WISC-R). Administered three subtests to 40 Anglo- and 40 Native-American Navajo subjects. Results indicated 15 of 79 items (information, similarities, and vocabulary subtests) were biased against the Navajo sample. (Author)

A comparison of bilingual Puerto Rican students' scores showed no significant differences between the Full Scale and the Verbal Scale scores on both tests, but significant differences between the Verbal and Performance Scale scores on both tests. Caution in testing bilingual children before determination of bilinguality is recommended. (Author)

Assessed test bias on the Wechsler Intelligence Test for Children-Revised (WISC-R) and Bender-Gestalt. On the Bender, evidence of bias was infrequent and irregular. On the WISC-R, group differences were most discernible for age, sex, family structure, and race. Consistent patterns of bias were not apparent among comparison groups. (Author)

In order to initiate appropriate programs for screening, early intervention, and meaningful psycho-educational programs, a children's community mental health center in Harlem, where over 95 percent of its clientele is black and/or Spanish speaking, requires, for all its referrals, an accurate assessment of intellectual strengths via an IQ battery.…

Twenty-one studies that reported mean score differences between the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) Full Scale are summarized. The differences are found to be minimal and are attributed to data bias and WJTCA's higher correlation with achievement. (EGS)

Concern about the possible bias of using only verbal assessments for the identification of intellectually gifted students led to an examination of the effect of incorporating nonverbal assessments of intelligence into the identification process. Two nonverbal instruments (Progressive Matrices and Test of Nonverbal Intelligence) were used in…

Urban EMR students' WISC-R scores (N=20) were compared with their previously administered WISC scores. The results of this study indicated that WISC-R scores in comparison to WISC scores appeared to be more stable in the lower IQ ranges and less vulnerable to cultural bias. (Author)
