Recent literature suggests a causal link between malnutrition and impaired cognitive development. A selective literature review indicates that the presence or absence of such a link cannot be established. A reanalysis of an experiment indicated after four years of treatment there was no association between cognitive and nutritional status.…

Recent research demonstrates that intelligence is much more complex than can be measured by standardized tests. External sociocultural factors influence the development of intelligence, and a distinction should be made between potential for learning and actual learning. (SK)

An unfolding model was selected for the scores on the Scale of Intellectual Development to take into account that, for stage-based instruments, agreement with a statement first increases as the student approaches the stage represented by the statement, then decreases as the student progresses beyond that stage. (Contains 21 references.) (Author)

The question of how to integrate developmental (Piagetian) and psychometric conceptions and assessments of intelligence is considered. A solution which incorporates the contributions of each position--intelligence as forms and as traits--is offered. Premises and objectives of each tradition are reviewed and compared. Overlaps make synthesis…

A brief review of these tests is provided, and it is concluded that the procedures possess a number of characteristics that make the evaluation of change in intelligence a tenuous proposition. (Author)

Persons representing the extremes of intelligence cannot be included in the same study unless they are approximately equated on mental age, in which case the relative performances of the extreme groups can provide useful information about the nature of intelligence. (Author/RD)

Seeing intelligence as neither strongly hereditary nor necessarily stable over time, and accepting the notion that it is a significant determinant of future occupational status, liberal psychologists and educators rely on the intervention of social institutions, primarily the school. The liberal view toward testing and intelligence is discussed.…

Assesses the complementary ability of childhood intelligence and learning-related behavior to explain variation in achievement outcomes. Results reveal substantial proportions of assigned grade variance explained primarily by learning behavior and achievement test score explained by intelligence. Implications for educational assessment and…

The third edition of the Wechsler Intelligence Scale for Children (WISC-III) is reviewed. A comparison of the WISC-III with the Weschler Intelligence Scale for Children-Revised (WISC-R) is included. Discusses shortcomings of the WISC-III while noting that overall, there are substantial improvements in the WISC-III over the WISC-R. (KW)

Ramey and Haskins report two findings of major importance: absence of decline in test scores and absence of mother-child correlation for treated children. Implications of these findings are discussed. (Author)

Researchers have concluded that the continued debate over the heredity-environment issue concerning the nature of intelligence is nonproductive. Recent evidence demonstrates that intellectual abilities can be improved with practice. Heredity may determine upper limits of abilities within individuals, but there is considerable room left for…

Reviews the literature on the relationship between schooling, IQ, and the cognitive processes presumed to underpin IQ. The data suggest the importance of quantity of schooling for IQ. Schooling fosters the development of cognitive processes that underpin performance on IQ tests. This development is unrelated to the quality of schools. (BC)

Reviews findings on the predictive validity of psychometric tests of intelligence. Concludes that conventional tests of intelligence can be useful but only if they are interpreted very carefully, taking into account the factors that can affect them, and in conjunction with other measures. (Author)

This three-part report discusses the concept of intelligence and its importance for educators. Part 1 considers the basic question of what intelligence is. Part 2 discusses the implications of notions of intelligence for schooling, dealing with both the training of content knowledge and the training of intellectual skills. Each of these first two…

Research and clinical findings indicate that psychologists need to be particularly aware of the variations between the cultural experience of the Native American and the Anglo child. Specific recommendations are presented concerning intellectual assessment of the Native American child. (Author/MH)
