The National Institute of Mental Health Research Domain Criteria (RDoC)
"A multifaceted construct comprising the processes that must be engaged during the planning and execution of a motor action in a context-appropriate manner. Component processes include action planning and selection, sensorimotor dynamics, initiation, execution, and inhibition and termination. Of note, these processes will often be recruited in conjunction with motivational processes described in other domains, as when appetitive motivations drive approach behaviors. This construct explicitly includes the modulation and refinement of actions during development and learning. The list of subconstructs is not intended to imply a specific order or sequence."
