Decoupling attention: tethered attention (Experiment 2 [E2], eye-contingent display) versus untethered (Experiment 1 [E1], mouse-contingent display)

Measure	Result	Interpretation
Change detection times and accuracy	E1 faster than E2	Untethered covert and overt attention yields a performance advantage over overt only
	No difference in detection accuracy	This advantage is not due to a speed–accuracy trade-off
Spatial distribution of fixations	More fixations between stimuli in E2 than in E1	Untethered covert and overt attention resulted in a different fixation strategy
