This study explored whether the reported inability of newborns to perceive object unity could result from the limited abilities of newborns to recognize the correspondence between 2 stimuli that were identical except for the presence or absence of an occluder. Five experiments were carried out using a visual habituation technique. The results of Experiment 1 indicated that newborns were capable of recognizing the perceptual correspondence between a nonoccluded and an occluded form. More intriguing, the outcomes of Experiments 2, 3, and 4 suggested that newborns find a partly occluded form to be more similar to a completely unoccluded form than to an unoccluded form containing a gap. Finally, even if newborns are able to perceive the correspondence between a partly occluded object and a complete form, the presence of this skill does not appear sufficient to imply the ability to manifest veridical object unity perception at birth (Experiment 5).
