Sternberg's Theory of Successful Intelligence proposes a broader and more comprehensive view of intelligence beyond traditional measures like IQ. The theory consists of three main components: analytical, creative, and practical intelligence. The theory suggests that gifted individuals have more developed analytical, creative, and practical…

The sustained attention of 16 mildly retarded and 16 nonretarded adults was assessed during 2 60-minute vigilance tests differing in memory demand. Performance of retarded subjects declined more rapidly in later stages than did that of the nonretarded subjects. Implications for the study of memory load are discussed. (SLD)

The relationship between speed of information processing (SIP) and psychometric intelligence was investigated by giving 60 college students (22 males and 38 females) 2 choice reaction time (RT) tests (modified Hick paradigm) and Raven's Advanced Progressive Matrices. Results support an association between intelligence and SIP. (SLD)

Forty-three adolescents (11-16 years of age) attending a health care program, Project Alternatives, for "street children" in Tegucigalpa, Honduras, drew randomly assigned pictures of either the ideal man or woman, engaged in some activity. These drawings were compared to samples from adolescents in various parts of the world to assess…

Using a modified Posner "encoding function" methodology, group differences in semantic encoding speed were assessed under conditions in which subjects encoded pictures of common objects to determine physical identity matches, name identity matches, and superordinate identity matches. Results of primary interest revealed group differences in basic…

Compared area scores from short-form version of Stanford-Binet Intelligence Test (Fourth) with those from long form for 33 gifted children. Found three of five mean difference contrasts were significantly different and correlation coefficients between corresponding area scores and Test Composite were statistically significant. Suggests that…

The present study reports data supporting the construct validity of the Kaufman Brief Intelligence Test (K-BIT; Kaufman & Kaufman, 1990), the Wechsler Intelligence Scale for Children-Third Edition (WISC-III; Wechsler, 1991), and the Adjustment Scales for Children and Adolescents (ASCA; McDermott, Marston, & Stott, 1993) through convergent…

Charles Spearman originally suggested in 1927 that the varying magnitudes of the mean differences between whites and blacks in standardized scores on a variety of mental tests are directly related to the size of the tests' loadings on g, the general factor common to all complex tests of mental ability. Several independent large-scale studies…

Magnetic resonance imaging was used to demonstrate that larger brain size (corrected for body size) was associated with higher intelligence quotient (IQ) for 40 right-handed college students grouped by high and average IQ and sex. Results suggest the relevance of brain size to intelligence test performance. (SLD)

Bilingual Navajo adolescents aged 14-16 were administered the Raven Standard Progressive Matrices (RSPM) and Comprehensive Tests of Basic Skills (CTBS). Correlations were moderate and were higher for females than for males. Norms were established for adolescent Navajos on the RSPM, a nonverbal test of intelligence and visual reasoning. (Author/GDC)

The Kaufman Assessment Battery for Children (K-ABC) and the Wechsler Intelligence for Children-Revised (WISC-R) were compared with respect to the magnitudes of the average White-Black differences in standardized scaled scores and in raw scores. Subjects were 172 fourth- and fifth-grade children matched in Black-White pairs. (Author/LMO)

Two studies with 658 white and 353 African-American elementary school children performing reaction time tasks are offered in support of Spearman's hypothesis about the relative size of the mean African-American-white differences on mental tests as a function of the tests' loadings on psychometric "g." (SLD)

Data were collected to develop special norms for the Vineland Adaptive Behavior Scales (VABSs) for educable mentally retarded (EMR) and trainable mentally retarded (TMR) children. These scales currently report special norms for retarded adults. The study also sought to determine if the low to moderate relationship typically found between…

A refined and extended analysis of variance (ANOVA) approach was used to investigate the pattern of relationships among arithmetic ability; reading ability; and general ability as assessed by teacher ratings and standardized tests, over a three-year period, with 54 educable mentally retarded children, initially 12 years old. (Author)

The New Hampshire statewide testing program was implemented to provide a data base for the evaluation of the effectiveness of Title I projects as required by Federal law. To accomplish this objective, achievement and intelligence tests were administered to children in Title I projects and regular programs in four elementary grades--2, 4, 6 and 8.…
