A case study of the psychometric characteristics of two profoundly gifted girls, one with autism spectrum disorder (ASD) and the other without ASD, is used to describe the nuances and subtleties most relevant in understanding the relationship between extreme giftedness and social difficulties. Through the presentation of the results from…

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…

A discussion of models of intellectual development and their application to education identifies the two major groups of such models and examines recent attempts to combine them. The two types of theories are described as the psychometric models, which see intellectual growth as the incremental amassing and associating of discrete ideas, and the…

Described the development and evaluation of a measure of cognitive belief systems and thinking styles. Reliability and validity results were poor for junior college students. For university and nonstudent populations, cognition scores discriminated social anxiety. The Cognition Scale of Assertiveness is a reliable and valid measure of cognitive…

DO CHILDREN RAISED IN ENVIRONMENTS ASSOCIATED WITH LATER DEFICITS IN PSYCHOMETRIC INTELLIGENCE SHOW ANY DEFICITS DURING INFANCY AND, IF SO, WHEN DO SUCH DEFICITS APPEAR AND WHAT ABILITIES ARE AFFECTED. ARE THE ENVIRONMENTAL FACTORS ASSOCIATED WITH EARLY DEVELOPMENT OF INTELLIGENCE. FIFTY-ONE SLUM INFANTS AND A CONTROL GROUP OF 51 NON-SLUM INFANTS…

Studied the relationship between mental age and progression toward Piaget's stages of concrete operations and formal operations in a sample of middle class children. Formal operations in preadolescence and adulthood are discussed in relation to IQ. (GO)

Children completed three types of equivalent cardination tasks which assessed the influence of different stimulus configurations (linear, linear-nonlinear, and nonlinear), and density of object spacing. Prior results reported by Siegel, Brainerd, and Gelman and Gallistel were not replicated. Implications for understanding cardination concept…

Raven's Progressive Matrices test items were analyzed for M demand (Pascual-Leone's developmental construct). Data on second- and third-grade subjects were analyzed for extent of absolute agreement of Raven and Figural Intersection Test (FIT) scores. Raw scores on the Raven could be deduced on the basis of FIT performance. (Author/RD)

Searching for an adequate method to investigate human development (especially the development of theoretical thinking) Vygotsky and his collaborators developed the causal genetic method. The basic idea of this method consists in the investigation of psychic functions and structures by their formation under controlled conditions (for instance via a…

Whether "psychometric" and "Piagetian" kinds of intelligence are similar is a question of whether they have similar courses of development with age. When using factor analysis to address this issue, age effects must be eliminated in order to assess relations among measured constructs. Reanalyses of previous results were…

Preschool-age children who are experiencing delays in physical, cognitive, communication, social, emotional, or adaptive development are often referred for a comprehensive assessment to make diagnostic determinations and to help develop appropriate interventions. Typically cognitive assessment has a key role in a comprehensive evaluation of a…
