Discusses the problems of using chronometric analysis, a common cognitive psychological method, for educational assessment. Suggests that cognitive assessment has not reached the precision needed to analyze individual differences. (FMW)

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…

The differences between edumetric and psychometric uses of tests were described and the relevance of the edumetric dimension for measuring student learning gains, especially in the context of individualized instruction involving multiple learning mode options, was clarified. Also, the procedures for edumetric reliability and validation assessment…

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…

An information processing approach was applied to the development and validation of a test battery intended for personnel selection, classification, and guidance; and design of training programs. The approach specifies that tests should measure specific cognitive processes and basic abilities, rather than prior experience. Tests should be short,…

The scientific concept of intelligence has been heavily influenced by the technology of measurement. The variables which can be measured have been made the operational definition of intelligence. This approach differs from a deductive approach, in which a theory of cognition in general is used to derive the sorts of measurements that must be taken…
