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. date: 1997 date_type: published publisher: Mahwah, NJ: Erlbaum pagerange: 727-732 refereed: FALSE citation: Taatgen, Niels A.
