Summary of object recall including results from Draschkow, Wolfe and Võ (2014) as well as results from the present experiment. Overall, with an increasing amount of information, the proportion of recalled objects increases. Furthermore, search produces better recall than intentional memorization when the tasks are performed in real world scenes or when non-scene images are supplemented by a flash preview of a complete scene and participants have 2500 msec to integrate target information with scene information (see Võ and Henderson, 2010). This suggests that integrating scene and target information in the first 2500ms of a search can cause stronger memory representations than intentional memorization.

Experiment	Stimulus	%recalled objects Search	% recalled objects Memorization	Effect of Task?
Draschkow, Wolfe and Võ, 2014; Exp. 2	Full scenes	44.6	31.6	yes (t-test)
Draschkow, Wolfe and Võ, 2014; Exp. 3	Randomly placed thumbnails of objects on non-scene backgrounds	19.6	24.2	no (t-test)
Experiment 1	Thumbnails of objects in their expected spatial relations on non-scene backgrounds	28.1	32.4	no (LMM)
Experiment 2	Objects photoshopped from scenes and placed on uniform background	39.1	43.6	no (LMM)
Experiment 3	Flash preview of full scene, 500ms integration time, photoshopped scene	39.7	35.6	no (LMM)
Experiment 4	Flash preview of full scene, 2500ms integration time, photoshopped scene	45.3	35.2	yes (LMM)
