The existence of the error-processing system has been inferred from the ""Error-Related Negativity,"" a component of the event-related brain potential elicited when human subjects commit errors in reaction-time tasks. It is proposed that the Error-Related Negativity is generated when a negative reinforcement learning signal is conveyed to anterior cingulate cortex via the mesencephalic dopamine system, and that this signal is utilized by anterior cingulate cortex to modify performance on the task at hand. Support for this proposal is provided using both computational modelling and psychophysiological experimentation." Made available in DSpace on 2015-09-25T20:45:48Z (GMT).
