Theoretical developments in decision field theory: comment on Tsetsos, Usher, and Chater (2010).

Tsetsos, Usher, and Chater (2010) presented several criticisms of decision field theory (DFT) involving its distance function, instability under externally controlled stopping times, and lack of robustness to various multialternative choice scenarios. Here, we counter those claims with a specification of a distance function based on the indifference and dominance dimensions. Using this distance function, we show that the instability problems do not arise when using the internally controlled stopping rule. In conclusion, we argue that the predictions of DFT do not conflict with the data presented and that the model yet provides a coherent and accurate account of multialternative choice phenomena.
