The examples of fragmented figures indicate that past experience with the objects represented affects our perception of the figures -- otherwise, we would be unlikely to hit upon the reorganization that allows us to see a face in profile. Past experience also affects our perception of these figures in another way. Robert Leeper, then at Cornell University, has shown that, if observers are presented with these fragmented figures again some time after they first succeed in identifying them, they can always perceive them correctly, even when shown them very briefly. This greater ease in reorganizing such figures is based on experience with the fragmented figures themselves rather than on experience with the objects they represent.
