The Cost of Accumulating Evidence in Perceptual Decision Making

J. Drugowitsch, R. Moreno-Bote, A. K. Churchland, M. N. Shadlen, A. Pouget
2012 Journal of Neuroscience  
Decision making often involves the accumulation of information over time, but acquiring information typically comes at a cost.  ...  Through a novel integration of diffusion models and dynamic programming, we were able to estimate the cost of making additional observations per unit of time from two monkeys and six humans in a reaction  ...  Introduction Decision making requires accumulation of evidence bearing on alternative propositions and a policy for terminating the process with a choice or plan of action.  ...
