Abstract

Two experiments used a dynamic control task (Berry & Broadbent, 1984) to examine the flexibility of experientially acquired knowledge. The results suggest that experientially acquired knowledge of this task is represented by a lookup table, not a set of tuned strategies. With practice, transfer to a new task was achieved through an extrapolation procedure. Experiment 2 demonstrated far superior task and transfer performance in participants trained with a combination of experiential practice and model-based knowledge. Transfer to new states was only possible when participants were provided with model-based knowledge through direct instruction. Also, providing model-based knowledge during practice resulted in a more flexible representation compared to providing it before or after practice. Pedagogical implications are discussed.
