No differences are found in scientific hypothesis formulation ability of 36 male and 50 female gifted ninth graders, but investigation of related variables indicates that hypothesis formulation may be independent of intelligence for high-ability students. A positive relationship also exists between quality and quantity of student responses. (SLD)

Regression analysis of results from 81 fourth graders (41 females) completing several assessments of metamemory indicate that relationships between metamemory and recall depend on assessment method and timing of the child's engagement with the recall task. General metamemory is significantly related to recall on the posttest and near transfer.…

Results of a survey of 47 state departments of public instruction regarding eligibility criteria for the identification of children with mental retardation are compared to results of 1981-82 and 1985-86 surveys. Although states continue to vary widely in definitions and procedures, more states now specify assessments of intelligence, adaptive…

A multivariate hierarchical model of specific cognitive abilities was fitted to data from 196 adopted and 213 nonadopted children from the Colorado Adoption Project and 120 of their siblings to assess genetic influence on specific mental abilities. Genetic effects occur in middle childhood that differentially influence mental ability scores.…

Two studies investigated (1) the development of children's implicit theories of self-attributes in the domains of intelligence, sociability, physical skills, and physical appearance; and (2) the degree to which conceptions of ability can be experimentally manipulated to predict achievement cognitions and behaviors.

Examined racial, gender, intellectual, achievement, and grade-level status of 344 students referred for learning disabilities diagnosis. Found that being white, older, and of higher intelligence and achievement were characteristics of those found ineligible despite severe discrepancy. Being female and less academically able were characteristics of…

Considers approaches to assessing writing disabilities that use theory-based process measures to explain discrepancies between intelligence quotient (IQ) and achievement; may define learning disabilities independent of IQ; and employ branching diagnosis based on selected tests rather than all tests in standard battery. Outlines model for using…

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)

The Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the Cognitive Test for the Blind were used to compare verbal and nonverbal abstraction ability of adults who became blind before age 2 or after age 5 (when expressive language would have been developed). No significant differences were found, but variability of scores on the WAIS-R…

Reports on a study that analyzed and compared a restricted set of full-text articles from a sub-specialty of biochemistry in terms of co-occurrences and co-absences of words. The consequences for the lexicographical approach to generating artificial intelligence from scientific texts are discussed. (JAK)

A review of research in distance education indicates that results are consistent in that there is no significant difference in achievement attributable to the delivery system. This paper attempts to look beyond these studies by examining research related to: learner interaction and control, two different approaches to multiple learning styles, and…

This article integrates the literature on intelligence and achievement outcomes in boys with Klinefelter syndrome (KS). It reports results of a study following 36 boys with KS and 33 sibling controls. Boys with KS demonstrated verbal cognitive deficits and significant underachievement in reading, spelling, and arithmetic, which increased with age.…

Relationships between brain-lesion location and behavior in 33 males and 31 females with unilateral lesions were studied. Statistical tests suggest that a single model can describe the relationships for females, but in males separate models of the relationships between lesion location, verbal intelligence quotient, and performance intelligence…

A study of 93 Spanish-speaking Latin American children of low socioeconomic background with reading difficulties found that, 4 years later, 17% had average reading ability, but 11% remained with severe reading difficulties. Characteristics examined include IQ, phonological processing, decoding ability, reading comprehension, and other verbal…

Beliefs of 153 academically talented students in grades 3 through 11 about the stability of intelligence paralleled a normal distribution. About half had easily modified views, and 9% were at risk of underachievement based on self-perceptions of low ability and the belief that intelligence is stable. (SLD)
