Comparison of Attention Bias Modification and Attention Control Training

Characteristic	Attention Bias Modification Training	Attention Control Training
Goal	Train attention bias away from threat	Normalize fluctuations in threat-related
		attention bias
Training	Over repeated trials patients are taught	Over repeated trials patients are taught
	to expect targets to appear at the	that emotional or neutral cues do not
	location of neutral rather than	predict target location and thus it is
	threat-related stimuli	preferable to ignore irrelevant
		contingencies
Evidence of clinical efficacy	Anxiety disorders (e.g., social anxiety disorder, generalized anxiety disorder)	PTSD
Effect on attention bias variability	No effect	Decrease
