%A Niels A. Taatgen %T A Rational Analysis of Alternating Search and Reflection Strategies in Problem Solving %X In this paper two approaches to problem solving, search and reflection, are discussed, and combined in two models, both based on rational analysis (Anderson, 1990). The first model is a dynamic growth model, which shows that alternating search and reflection is a rational strategy. The second model is a model in ACT-R, which can discover and revise strategies to solve simple problems. Both models exhibit the explore-insight pattern normally attributed to insight problem solving. %K problem solving, insight theory, dynamical systems, ACT-R, cognitive modelling, architectures of cognition, reversal-shift learning, learning %P 727-732 %E Michael G.
