N2 - To date the exact neuronal implementation of decision confidence has been subject to little research. Here we explore electroencephalographic correlates of human choice certainty in a visual motion discrimination task for either spatial attention or motor effector cue instructions. We demonstrate electrophysiological correlates of choice certainty that evolve as early as 300 ms after stimulus onset and resemble the primary visual motion representations in early visual cortex. These correlates do not emerge unless or until the subject unambiguously knows which of the competing visual stimuli is actually relevant to behaviour. They extend beyond stimulus presentation up to the motor response but are independent of the motor effector. Our findings suggest that perceptual confidence evolves in parallel with representations of stimulus properties and is dedicated to one specific aspect of the visual world. Its electroencephalographic correlates can be disentangled from representations of sensory evidence, objective discrimination performance and overt motor behaviour.
