Elkind, David – Intelligence, 1981
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…

Lynn, Richard; Longley, David – Intelligence, 2006
A number of studies in the United States have found that Jews obtain higher average IQs than white gentiles. This paper examines whether this is also the case in Britain. Three early studies are summarized that found that Jews in Britain have mean IQs in the range of 110-113. New data are presented for two nationally representative samples of 7-16…

Spitz, Herman H. – Intelligence, 1981
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)

Ramey, Craig T.; Haskins, Ron – Intelligence, 1981
In this response to the critiques by Jensen and McVicker Hunt, we focus on the meaning of g, the permanence of effects produced by early education, and the educational significance of IQ gains produced by early education programs. New longitudinal data from our study presented. (Author/RD)

Wolff, JosePh L. – Intelligence, 1979
Explanations of differences in IQs of Northern and Southern Blacks focus on selective migration (hereditarians) or environmental causes such as education, discrimination and cultural deprivation. In this paper the environmentalist position is questioned and certain neglected features of Lee's data are construed as providing strong evidence for…

Keil, Frank C. – Intelligence, 1982
An approach to intelligence which emphasizes domain-specific constraints on knowledge structures is compared to information processing approaches. The evaluation of any cognitive ability as being intelligent crucially depends on prior specification of the formal constraints on the domains of knowledge from which that ability originates.

Carroll, John B. – Intelligence, 1997
R. Herrnstein and C. Murray, in "The Bell Curve," stated six propositions concerning a "g" factor of intelligence. These propositions are found to be reasonably well supported in the scientific literature. These conclusions can be reached whether or not one accepts Herrnstein and Murray's claims about the social significance of…

Jensen, Arthur R. – Intelligence, 1981
The Ramey and Haskins intervention experiment is examined. Narrow transfer of training from cognitive intervention techniques to IQ test performance in early childhood, rather than enhancement of the g factor itself, is hypothesized as a cause of the typical fadeout of early IQ gains in later childhood.

Whitely, Susan E. – Intelligence, 1980
This article examines the potential contribution of latent trait models to the study of intelligence. Nontechnical introductions to both unidimensional and multidimensional latent trait models are given. Multidimensional latent trait models can be used to test alternative multiple component theories of test item processing. (Author/CTM)

Spitz, Herman H. – Intelligence, 1978
Mentally retarded individuals have more difficulty dealing with strategic games and puzzles than other tasks. Games have been played since ancient times and throughout the world, with performance indicating wisdom. Games invariably express certain universal intellectual traits. Mancala and Three in a Row games are briefly described. (Author/RD)

Hunt, J. McVicker – Intelligence, 1981
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)

Plomin, Robert; DeFries, J. C. – Intelligence, 1980
Extensive data on twins, nontwin siblings, siblings separated by adoption, and parent-child similarity indicate that the heritability of intelligence is closer to .50 than to .70. Differences could be due to environmental or genetic changes in the population, or to methodology. (Author/CP)

Glaser, Robert; Pellegrino, James W. – Intelligence, 1979
Current studies of cognition emphasize the contrast between two approaches to analysis of individual differences. It is concluded that the cognitive components approach incorporates the cognitive correlates approach, avoids the inadequacy of correlational methods, and models individual differences on various dimensions of cognitive functioning.…
