Expert camouflage-breakers can accurately localize search targets

Cognitive Research: Principles and Implications

Table 1 Measures of the precision of the localizations in Experiment 1

	Target present		Target absent
	Free viewing	Stimulus duration: 50 ms	Free viewing	Stimulus duration: 50 ms
Mean reaction time (ms) ± SD	595 ± 95	586 ± 103	604 ± 97	593 ± 103
Mean localization distance ± SD^a	1.36 ± 0.68	1.44 ± 0.71	1.38 ± 0.73	1.45 ± 0.74

^aDistance was calculated as the Euclidean distance (in degrees of arc) between the reported location of the target and its actual location during each trial
