Classification framework for patterns of cognitive-motor interference based on changes in performance of each task in the dual-task condition relative to single-task performance

		Cognitive Performance
		No Change	Improved	Worsened
Motor Performance	No Change	No dual-task interference	Cognitive facilitation	Motor-related cognitive interference
	Improved	Motor facilitation	Mutual facilitation	Motor-priority trade-off
	Worsened	Cognitive-related motor interference	Cognitive priority trade-off	Mutual interference
