Abstract
Percep-tual differences between normals and schizophrenics revealed by traditional size-constancy experiments are questionable because of S variability, procedural difficulties, and problems inherent in traditional psy-chophysical methods. A review of the literature reveals few consistent results. The present study compared normals, paranoid schizophrenics, and nonparanoid schizophrenics on a size-constancy task which allowed derivation of additional dependent variables from signal-detection analysis and uncertainty analysis. No group differences were revealed using the size-constancy procedure, but signal-detection analysis indicated nonparanoid schizophrenics were significantly lower in perpetual sensitivity. Uncertainty analysis revealed additional response dispositions characteristic of the schizophrenic groups.Keywords
