Abstract
The hypothetical cost-conflict monitor: is it a possible trigger for conflict-driven control mechanisms in the human brain?
Highlights
Flexible goal-directed behavior requires a performance monitoring system to monitor behavioral consequences in order to detect the need for further adjustments and control
According to the reinforcement learning (RL) model, negative reward prediction errors (RPEs) sent to the anterior cingulate cortex (ACC) generate the error-related negativity (ERN) and the feedback-related negativity (FRN)
The conflict-monitoring theory (CMT) argues that the N2 and the ERN are electrophysiologically correlated with pre-response and post-response conflict signals, respectively
Summary
Flexible goal-directed behavior requires a performance monitoring system to monitor behavioral consequences in order to detect the need for further adjustments and control. The reinforcement learning (RL) account of performance monitoring and control is one of the influential theories to the field (Holroyd and Coles, 2002; Holroyd et al, 2005). The conflict-monitoring theory (CMT) proposes that the performance monitoring system monitors for the coactivation of mutually incompatible response tendencies or conflict during response selection.
