A study with 40 normal adult subjects indicates that the ANT produces reliable single subject estimates of alerting, orienting, and executive function, and further suggests that the efficiencies of these three networks are uncorrelated.

An integrated Attention Network Test (ANT) to measure the efficiency of the three networks with adults was adapted to study the development of these networks during childhood and suggested that children like adults showed independence between theThree networks under some conditions.
The activation of attentional networks

The fMRI results suggest that the functional contrasts within this single task differentially activate three separable anatomical networks related to the components of attention.
Testing the behavioral interaction and integration of attentional networks
It is found that whereas alerting improves overall response speed, it exerts negative influence on executive control under certain conditions, and the hypothesis of functional integration and interaction of these brain networks is supported.
Common and distinct networks underlying reward valence and processing stages: A meta-analysis of functional neuroimaging studies

To better understand the reward circuitry in human brain, we conducted activation likelihood estimation (ALE) and parametric voxel-based meta-analyses (PVM) on 142 neuroimaging studies that examined…
Cognitive and Brain Consequences of Conflict

The behavioral and fMRI results taken together seem to argue against a single unified network for processing conflict, but instead support either distinct networks for each conflict task or a single network that monitors conflict with different sites used to resolve the conflict.
Does the emotional go/no-go task really measure behavioral inhibition? Convergence with measures on a non-emotional analog.

The results suggest that the basic neuropsychological constructs of the original go/no-go task were preserved in the emotional adaptation.
Development of attentional networks: An fMRI study with children and adults
The data suggest that there is a transition from functional yet immature systems supporting attentional functions in children to the more definitive adult networks and that the differences observed may reflect both developmental changes in cognitive strategies and morphology.
Assessing the molecular genetics of attention networks
The ANT is validated as an endophenotypic assay suitable for assessing how genes influence certain anatomical networks that may be disrupted in various psychiatric disorders and suggests that genetic variation may underlie inter-subject variation in the efficiency of executive attention.
The Relation of Brain Oscillations to Attentional Networks
The attention network test is used to separate three anatomically defined brain networks that carry out the functions of alerting, orienting, and executive control of attention and found that each attentional network has a distinct set of oscillations related to its activity.
