Addresses the theoretically important question of whether g is merely an artifact of the method of constructing psychometric tests and the mathematical operations of factor analysis or whether it has an authentic claim to represent some natural phenomenon that exists independently of psychometrics and factor analysis.

The primary goal of this review is to acquaint developmental psychologists who have had little experience in the study of individual differences in cognition with some of the basic rules that govern this type of research. A second goal is to stimulate researchers to consider the potential benefits of studying differences among individuals whose…

Delineates the current consensus regarding the nature and the development of intellectual ability. Examines when one would expect general abilities to moderate the relationship among domain-specific and other processes. Reviews recent studies in which general abilities were used as independent variables or covariates. Suggests that generally,…

The information-processing approach and results of research on spatial ability are analyzed. Performance consists of a sequence of distinct mental operations that seem general across subjects, and can be individually measured. New interpretations for some classical concepts in psychological testing and procedures for abilities are suggested.…

A review of available literature on extended school year (ESY) programming (1972-1988) is structured around an exploration of 11 questions developed by special education administrative personnel. Issues addressed include how regression/recoupment (R/R) is measured; the related concepts of generalization and maintenance; how R/R is related to…

The construction of cognitive tests is largely based on a Thurstonian model of the structure of the intellect, with test content described in terms of loadings on broad constructs called factors. Knowledge of factorial content of a test does not necessarily correspond to knowledge of mental activities elicited by test performance. Modern cognitive…

Fifty-five recent studies of individual differences (IDs) in elementary cognitive tasks (ECTs) are reviewed. Twenty-five data sets are examined, analyzed, or reanalyzed by factor analysis. The following promising dimensions are identified: basic perceptual processes, reaction and movement times, mental comparison and recognition tasks, retrieval…

Philosphical principles provide the context for the Soviets' psychological theory (in particular, the "zone of proximal development" concept); this theory then shapes psychoeducational practice. (GDC)

The nature of the cognitive style of field articulation and its relationship to differentiation of personality are discussed. A short historical summary of research on field dependence-independence is presented, and problems of measurement, stability, and evolution of the dimension of field articulation are discussed. The connections between field…
