Quality of evidence for perceptual decision making is indexed by trial-to-trial variability of the EEG

R. Ratcliff, M. G. Philiastides, P. Sajda
2009 Proceedings of the National Academy of Sciences of the United States of America  
This makes it impossible to determine, for a single trial of an experiment, the quality of the evidence on which a decision is based.  ...  A fundamental feature of how we make decisions is that our responses are variable in the choices we make and the time it takes to make them.  ...  U nderstanding the behavioral significance of trial-to-trial variability in neural activity is central to systems neuroscience in general, and the neural bases of decision making in particular.  ...
