How do people select among different strategies to accomplish a given task? Across disciplines, the strategy selection problem represents a major challenge. We propose a quantitative model that predicts how selection emerges through the interplay among strategies, cognitive capacities, and the environment. This interplay carves out for each…

A model of information processing has been developed that combines concepts from the study of attention and the study of problem solving. The model has been realized as a computer program and used to simulate a variety of phenomena from the attention and performance literature. (Author/LMO)

A theory is proposed of the processes which enable a subject to learn while solving a problem. One subject's protocol--including 224 steps and taking 90 minutes--is described. Adequacy of the mechanisms is guaranteed by a computer simulation of the processes in an adaptive production system. (Author/GDC)
