The Cognitive Proficiency Index (CPI) developed for the most recent Wechsler intelligence scales comprises the working memory and processing speed subtests. It reflects the proficiency and efficiency of cognitive processing and provides another lens for analyzing children's abilities assessed by the Wechsler Intelligence Scale for Children--Fourth…

This research has demonstrated that first, short term memory (Jensen's Level I) has only a moderate index of heritability; second, that the general intellective factor g' (Jensen's Level II) has somewhat high heritability; and third, that no evidence of hereditary variation appeared in the Figural and Verbal Divergent Thinking measures.…

It was concluded that while retinoblastoma per se is not associated with intellectual superiority or inferiority, retinoblastoma associated with blindness may result in selective cognitive superiority. (Authors)

Comparison is made between the very high proportion of adolescents found by Somerville to be formal operational thinkers, and the much lower proportion found by Lovell. Evidence about the representativeness of Somerville's sample is analyzed suggesting that it is comparable with that of an average English selective school. (Editor)

Knowing and having just learned are not exactly the same thing. Neither is the fact that a student can think necessarily evidence that he has been taught. This provocative study raises more questions than it answers. (Editor)

A battery of 28 individually administered tests, comprised of measures derived from the work of Piaget, of simple and complex learning, of language, short-term memory, long-term memory and intelligence were given to 210 children aged 5 to 6 during their first year of schooling. (Editor)

The Picture Completion subtest of the Wechsler Preschool and Primary Scale of Intelligence was included in this study as a measure of analytic functioning, an aspect of psychological differentiation. Twelve of the 23 items on the test were taken from the WISC and 11 were new. The child is shown a series of 23 pictures, each of which has some…

This research investigates the relationship between creativity as a cognitive process and the level of moral reasoning as well as the relationship between moral reasoning level and various combinations of creativity and intelligence. (Author/RK)

Describes the construction of a knowledge representation from the identification of the problem (nephrotic syndrome) to a running computer simulation of causal reasoning to provide a vertical slice of the construction of a cognitive model. Interactions between textbook knowledge, observations of human experts, and computational requirements are…

Butch and Slim was written as a response to a need for a rather specialised group of items in the Reasoning sub-scale of the British Intelligence Scale. (Author)

Part of a sustained program that has involved the design of personally tailored information systems responsive to the needs of scientists performing common research and teaching tasks, this project focuses on the procedural and content requirements for accomplishing need diagnosis and presents these requirements as specifications for an…
