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.

Anterior cingulate cortex, error detection, and the online monitoring of performance.
Results confirm that this region shows activity during erroneous responses, but activity was also observed in the same region during correct responses under conditions of increased response competition, which suggests that the ACC detects conditions under which errors are likely to occur rather than errors themselves.
Explaining the many varieties of working memory variation: Dual mechanisms of cognitive control.
Temporal dynamics of brain activation during a working memory task
Functional magnetic resonance imaging is used to examine brain activation in human subjects during performance of a working memory task and to show that prefrontal cortex along with parietal cortex appears to play a role in active maintenance.

It was found that the FPN's brain-wide functional connectivity pattern shifted more than those of other networks across a variety of task states and that these connectivity patterns could be used to identify the current task.

Functional magnetic resonance imaging is used to probe PFC activity during a sequential letter task in which memory load was varied in an incremental fashion, providing a "dose-response curve" describing the involvement of both PFC and related brain regions in WM function.

The results are consistent with the hypothesis that the ACC serves as a generic detector of processing conflict arising when low-frequency responses must be executed, but also leave open the possibility that further functional specialization may occur within ACC subregions.
Event perception: a mind-brain perspective.

A theory according to which the perception of boundaries between events arises from ongoing perceptual processing and regulates attention and memory is proposed.
