Distance constancy was studied in schizophrenics and normals.
Distance constancy is poorer in schizophrenics than in normals.
This is related to their poorer size constancy.
The result of poor distance constancy is that visual perception in schizopbrenics is lacking in depth and that these patients live in a “flatter” world.
The implications of this finding are discussed.
