Table 1. Effect of Target on Response Time Measures in Visual Search.

Task	Independent variable	Log Transformed RT	Log Transformed RT Intercept	Log Transformed RT Slope
Conjunction Search
	Target Present	2.82±.02 [661 ms]	2.77±.02 [589 ms]	.002±.0004 [3 ms/item]
	Target Absent	2.94±.02 [871 ms]	2.82±.02 [661 ms]	.0048±.0004 [12 ms/item]
	Target Effect	F(1,2003) = 1180.86; p<.001	F(1,329) = 31.88; p<.001	F(1,17) = 19.30; p<.001
Spatial Configuration Search
	Target Present	3.07±.03 [1175 ms]	2.94±.02 [871 ms]	.005±.0004 [15 ms/item]
	Target Absent	3.35±.03 [2239 ms]	3.12±.02 [1318 ms]	.007±.0004 [41 ms/item]
	Target Effect	F(1,1571) = 3805.32; p<.001	F(1,329) = 910.52; p<.001	F(1,329) = 59.76; p<.001

This table represents the main effect of target from the ANOVA—a standard effect in visual search where target present trials have a faster response time (RT) than target absent trials. The log transformed response time (RT), RT intercept, and RT slope in both the conjunction search task and in the spatial configuration search task show this effect.
