This study investigates the relationships of domain-general cognitive abilities and domain-specific verbal and mathematical abilities to students' educational characteristics when two theoretically grounded, but competing structural models are applied. In the standard model, a single latent ability causes interindividual differences in the…

THIS BIBLIOGRAPHY LISTS MATERIAL ON VARIOUS ASPECTS OF HUMAN INTELLECT. APPROXIMATELY 50 UNANNOTATED REFERENCES ARE PROVIDED TO DOCUMENTS DATING FROM 1955 TO 1966. BOOKS, REPORTS, JOURNAL MATERIALS, AND SOME UNPUBLISHED TITLES ARE LISTED. SUBJECT AREAS INCLUDED ARE (1) INTELLECTUAL DEVELOPMENT, (2) ABILITY DIFFERENCES BETWEEN INDIVIDUALS, RACES,…

This evaluation of cognitive change in Head Start children focused on changes in performance as opposed to changes in competence; specifically, that Binet test performance improves as a function of experience with Binet examiners. The study involved 93 children assigned to four groups who were tested for IQ gains during a 6-week Head Start program…

This report discusses the outcomes of a study that examined 216 comparably aged children and adolescents (ages 2-18) with fragile X or autism to determine whether longitudinal change in cognitive ability and adaptive behavior was similar in the two groups. Results found decreases in Intelligence Quotient scores in young children with fragile X as…

The author presents a discussion of certain portions of Arthur Jensen's controversial article. The general conclusion is that Jensen has not provided substantial evidence that there are differences in neural structure among children from different social or ethnic groups which are genetically determined. The reviewer reacts to Jensen's conclusion…

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. (Author/RD)

Claims in "The Bell Curve" that Head Start and other early intervention programs are a failure and a waste of funds depend on a notion of cognitive ability reduced to IQ. They ignore other studies that demonstrate the success of such programs and that, consistent with Piagetian views, recognize the interrelationships of cognitive,…

Contents of this symposium comprises: Introduction (W. B. Dockrell); The Genetics of Intelligence (Sir C. Burt); Structuring Mental Acts (P. R. Merrifield); A "Piagetian" Test of Cognitive Development (R. D. Tuddenham); The British Intelligence Scale (R. W. Warburton); Intelligence (P. E. Vernon); Hierarchical Theories of Mental Ability…

Change in cognitive functioning is an important aspect of human aging and a key outcome in many medical conditions. However, cognitive change can rarely be measured directly, since prior cognitive data do not exist for most people. We examined the criterion validity and one-year stability of the difference between National Adult Reading Test…

Two studies examined modifiability in intellectual functioning in older adults. The fluid-crystallized theory provided a theory base for the research. (Fluid intelligence follows a normative decline through adulthood, while crystallized intelligence remains stable or even increases.) In the first study thirty subjects (average age 69.2)…

Cognitive style identifies the ways individuals react to different situations. Cognitive styles include stable attitudes, preferences, or habitual strategies that distinguish the individual styles of perceiving, remembering, thinking, and solving problems. Intended for researchers, psychologists, child development specialists, and early childhood…

THIS PAPER (WHICH WAS PREPARED FOR A SYMPOSIUM ON "THE STUDY OF PERSONALITY" AT RICE UNIVERSITY, HOUSTON, NOVEMBER, 1966) REVIEWS THE ADVANCES MADE BY INTERDISCIPLINARY LINGUISTIC RESEARCH INTO THE EFFECTS OF EARLY BILINGUALISM. USING THE SAUSSUREAN MODEL OF THE LINGUISTIC SIGN, A DISTINCTION IS MADE BETWEEN "COORDINATE" AND "COMPOUND" BILINGUALS.…

Reviews the current theories concerning individual differences in cognitive functioning. While some argue that heredity places a genetic cap on intellectual development, others emphasize the dynamic interrelationship between cultural and environmental factors. Concludes that intelligence is more complex than the heredity advocates allow. (MJP)

Psychologists and a few sociologists have provided the academic respectability for the political rationale that the American body politic's civil rights indigestion needs a resurrected, separate but equal diet. Today, it is intellectually respectable to question the genetic equality of whites and blacks, to assert the cognitive incapacities of…

This final report reviews the second phase of a life-span study of boys with fragile X syndrome (FSX), the most common known inherited cause of mental retardation. Males with the syndrome are more severely affected than females and in males, delays are usually evident in all the developmental domains, although cognitive and communication skills…
