Picture stimuli and presentation sequence used in this study. Each picture (P) consisted of an object placed within a background scene. Pictures were presented in quartets with objects and scenes selectively repeated. Four types of quartets were used: (1) four repeated, identical pairings of object and background scene (OO); (2) an identical object repeated in four novel background scenes (ON); (3) novel objects in each of four repeated background scenes (NO), or (4) four novel objects paired with four novel background scenes (NN). Each picture was presented for a stimulus duration (SD) of 1500 msec with an IPI of 250 msec. Quartets were presented with a mean IQI of 9000 msec.
