Decision-making components and times revealed by the single-trial electroencephalogram.

ABSTRACT: Decision-making stems from a sequence of information processing steps between the onset of the stimulus and the response. Despite extensive research, uncertainty remains about the actual cognitive sequence involved that leads to the reaction time. Using the hidden multivariate pattern method, we modeled the single-trial electroencephalogram of participants performing a decision task as a sequence of an unknown number of events estimated as trial-recurrent, time-varying, stable topographies. We provide evidence for five events occurring during participants' decision-making with two visual encoding events and three events capturing respectively attention orientation, decision, and motor execution. This interpretation is supported by the observation that a targeted manipulation of stimulus in
