This study investigated 8‐month‐old infants' perception of object permanence in an extension of the rotating screen studies by Baillargeon (1987) and Baillargeon, Spelke, and Wasserman (1985). Using computer‐animated stimuli similar to the “live” stimuli used by Baillargeon and her colleagues (Baillargeon, 1987; Baillargeon et al., 1985), 48 8‐month‐old infants were habituated to 1 of 4 computer‐animated events and then tested on all 4 events. The events involved a screen that rotated in either a 180° or 120° arc*** and a block that either was sitting in the path of the rotating screen or absent from the event. The results provided no evidence that infants responded on the basis of the possibility or impossibility of the events as claimed by Baillargeon and her colleagues, but instead indicated that the infants responded on the basis of perceptual novelty. These results are consistent with the findings of Schilling (this issue) and Bogartz, Shinskey, and Schilling (this issue). Taken together, along with the findings of Rivera, Wakeley, and Langer (1999), these more recent findings suggest that Baillargeon's (1987; Baillargeon et al., 1985) results should not be interpreted as definitive evidence of object permanence in very young infants.
