<p data-rte-fromparser="true" data-rte-empty-lines-before="1">A more comprehensive and recent theory describes the ACC as a more active component and poses that it detects and monitors errors, evaluates the degree of the error, and then suggests an appropriate form of action to be implemented by the motor system.

The dorsal part of the ACC seems to play a key role in reward-based decision-making and learning. The rostral part of the ACC, on the other hand, is believed to be more involved with affective responses to errors.

Because the ACC is intricately involved with error detection and affective responses, it may very well be that this area forms the bases of self-confidence.
