RDoC Classification
Description
Attention refers to a range of processes that regulate access to capacity-limited systems, such as awareness, higher perceptual processes, and motor action. The concepts of capacity limitation and competition are inherent to the concepts of selective and divided attention.

Paradigms
Target detection tasks in the absence of competition are considered measues of sustained attention, and not selective or divided attention, which are subsumed under cog control
