title: How to discriminate conclusively among different models of decision making?
abstract: A popular and successful class of decision-making models (the "evidence accumulator" models) has been recently challenged by a new hypothesis called the urgency-gating model. Hawkins et al. (J Neurophysiol 114: 40-47, 2015) used a sophisticated curve-fitting procedure to show that these models are discriminable and thus testable in constant evidence tasks. In this Neuro Forum article I raise possible limitations of such an approach, discuss some of its implications, and propose alternative solutions.
