Abstract:

Memory for the positions of objects in natural scenes was investigated. Participants viewed an image of a real‐world scene (preview scene), followed by a target object in isolation (target probe), followed by a blank screen with a mouse cursor. Participants estimated the position of the target using the mouse. Three conditions were compared. In the target present preview condition, the target object was present in the scene preview. In the target absent preview condition, the target object not present in the scene preview. In the no preview condition, no preview scene was displayed. Localization accuracy in the target present preview condition was reliably higher than that in the target absent preview condition, which was reliably higher than localization accuracy in the no preview condition. These data demonstrate that participants can remember both the spatial context of a scene and the specific positions of local objects.
