In this study, we examined 4.5-month-old infants’ visual completion of self-occluding three-dimensional objects. A previous study on this topic reported that 6-month-old, but not 4-month-old infants extrapolate a convex, symmetric prism from a limited view of its surfaces (Soska & Johnson, 2008). As of yet, studies on the development of amodal completion of three-dimensional, self-occluding objects are scarce. Given 4-month-old infants’ abilities to derive three-dimensional shape from a variety of visual cues, three-dimensional amodal completion may well depend on the perceptual strength of three-dimensionality in the stimulus displays. The first experiments (1A and 1B) tested this hypothesis by means of…

 Research highlights: ► 4.5-month-old infants can amodally complete self-occluding 3D objects. ► Volume completion in young infants is facilitated by sufficient depth-cues. ► Volume completion in young infants occurs in absence of contour or surface relatability.
