Conflict monitoring and cognitive control.
TLDR
Two computational modeling studies are reported, serving to articulate the conflict monitoring hypothesis and examine its implications, including a feedback loop connecting conflict monitoring to cognitive control, and a number of important behavioral phenomena.Abstract:
A neglected question regarding cognitive control is how control processes might detect situations calling for their involvement. The authors propose here that the demand for control may be evaluated in part by monitoring for conflicts in information processing. This hypothesis is supported by data concerning the anterior cingulate cortex, a brain area involved in cognitive control, which also appears to respond to the occurrence of conflict. The present article reports two computational modeling studies, serving to articulate the conflict monitoring hypothesis and examine its implications. The first study tests the sufficiency of the hypothesis to account for brain activation data, applying a measure of conflict to existing models of tasks shown to engage the anterior cingulate. The second study implements a feedback loop connecting conflict monitoring to cognitive control, using this to simulate a number of important behavioral phenomena.read more

The neural basis of human error processing: Reinforcement learning, dopamine, and the error-related negativity.
TL;DR: This paper presented a unified account of two neural systems concerned with the development and expression of adaptive behaviors: a mesencephalic dopamine system for reinforcement learning and a generic error-processing system associated with the anterior cingulate cortex.

Conflict monitoring and anterior cingulate cortex: an update
TL;DR: Recent research has begun to shed light on the larger function of the ACC, suggesting some new possibilities concerning how conflict monitoring might fit into the cingulate's overall role in cognition and action.

TL;DR: Using the Stroop color-naming task and controlling for repetition effects, it is demonstrated that ACC conflict-related activity predicts both greater prefrontal cortex activity and adjustments in behavior, supporting a role of ACC conflict monitoring in the engagement of cognitive control.

The Role of the Medial Frontal Cortex in Cognitive Control.
TL;DR: New findings in cognitive neuroscience concerning cortical interactions that subserve the recruitment and implementation of cognitive control are evaluated, suggesting that monitoring-related pMFC activity serves as a signal that engages regulatory processes in the LPFC to implement performance adjustments.

TL;DR: The chapter discusses two important directions of research to improve learning algorithms: the dynamic node generation, which is used by the cascade correlation algorithm; and designing learning algorithms where the choice of parameters is not an issue.
