Four baboons (Papio papio) were tested in a computerized two-alternative forced choice task in which partially occluded graphic Stimuli were shown either on linear perspective backgrounds depicting a corridor or on uniformly black backgrounds. The results indicated that baboons complete partly Occluded stimuli and that amodal completion is facilitated by the display of pictorial background depth Cues. Inter-individual differences emerged in the ability to extrapolate three dimensional information from two-dimensional visual information.
