Research on aptitude-instructional treatment interactions has shown that the relation of general ability to learning tends to increase as instruction places increased information processing burdens on learners and to decrease as instruction is designed to reduce the information processing demands on learners. This report summarizes a research…

Reviews concepts of aptitude and aptitude-treatment interaction (ATI) and summarizes lessons learned in ATI research on educational treatments to help ATI research on psychotherapeutic treatments. Research design and data analysis recommendations address aptitude distributions, multivariate aptitude complexes, detective work with scatterplots,…

The first and founding conference of the European Association for Research on Learning and Instruction was held in Belgium from June 10-13, 1985. This article concentrates on highlights that suggest intersections between three of the six conference themes: problem-solving; cognition-motivation interaction; and individual differences. Conference…

This article reviews progress toward the development of a cognitive theory of aptitude for learning and presents descriptive and precriptive goals for aptitude theories. Preliminary hypotheses about the nature of cognitive processes in aptitude for learning from instruction are reviewed. Twelve constituent points of the descriptive theory are…

The theoretical and methodological concepts for research on aptitudes as cognitive processes are discussed. Individual differences constructs are reviewed in relation to cognitive processing models, and studies of short-term memory are reviewed. A coordinated approach to the study of aptitude as information processing is recommended. (Author/RD)

This document focuses on how research which investigates the interaction between learning abilities and instructional treatments (Aptitude Treatment Interaction or ATI) should proceed. Previous research related to ATI is evaluated in the context of the ATI premise that characteristics of learners affect their attainment of educational goals…

Discusses research areas proposed in the National Research Council Report: aptitude assessment, alternative treatment design, and outcome assessment. Urges that global IQ scores be included in aptitude assessment, adaptive strategies be employed in treatment, and progress toward both common and special education goals be traced within an…
