This study examines the cognitive processes of strategic decision making in simulated dynamic environments. The experimental study using two different types f interactive decision making games found that high performers adopted more feedforward strategy and they pursued more model expansion than low performers did. These findings were confirmed in a supplementary study which manipulated to force the subjects to use feedforward strategy in there dynamic decision making. Results suggest that, in dynamic decision environment, the performance relies on the decision making strategy that manages adopt, i.e., feedforward strategy rather than feedback strategy. This study concludes by discussing its implications for theoretical development and strategic decision makers in complex dynamics environments.
