Scanning time of schizophrenics and normals for visual designs.

Measured the time to locate a target design in an array of 4 designs by 12 process and 12 reactive schizophrenics and 12 hospitalized and 12 nonhospitalized normal controls. Designs and arrays differed in the size of the rotation and reflection equivalence sets from which they were selected. Differences in mean reaction time (RT) attributable to these characteristics were found as expected. Schizophrenics performed slower than the nonhospitalized normals. The mean RT of hospitalized normals, mostly spinal cord injury patients, fell between that of the process and reactive schizophrenics. No Group * Stimulus Condition interaction effects were found. Results are interpreted as not supporting leading theories of schizophrenic deficit. (21 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
