| Abstract: | Replicated the experimental procedures on which a tridimensional model of schizophrenic perceptual functioning was based, other potentially relevant procedures included, and the resultant relationships delineated and tested through multivariate statistical techniques. Factor analysis supported the existence of the 3 dimensions of the original model stimulus intensity control, scanning control, and field articulation. Through cluster analysis there emerged groups of Ss whose differing perceptual styles paralleled the previously reported pattern of differences between paranoid and nonparanoid schizophrenics. Other results made several major qualifications of the original theory necessary: (1) perceptual inefficiency and anchoring emerge as additional meaningful dimensions of perceptual functioning; (2) behavioral guardedness replaces coherent paranoid delusions as a significant correlate of scanning; and (3) stimulus augmentation is related to strong internal affect only among acute patients; among chronic patients the relationship is reversed.
