An evaluation of the clinical utility of the Draw-a-Person Test.

Evaluated the reliability and validity of objective scoring procedures on the Draw-A-Person Test. Handler's (1967) scales and other ratings of overall quality were used. Ss were mentally retarded persons, hospitalized and non-hospitalized psychotics, and normals. Naive raters scored the protocols under blind conditions. Reliability estimates for both sets of scales ranged from .42 to .78. Positive evidence also is presented, which indicates that overall quality does relate to overall level of psychological adjustment. Group and scale differences are discussed.

Hemispheric dysfunction in schizophrenia: assessment by visual perception tasks.

Before and after a double-blind trial of haloperidol vs. mesoridazine, 24 hospitalized schizophrenics performed visual perception tasks designed to assess function of the cerebral hemispheres. Tasks involved identifying as "same" or "different" two images (either letters, digits, or unfamiliar shapes) projected tachistoscopically to the right or left visual field or to both together. Multivariate analysis of variance related response latency and accuracy to task type, hemisphere stimulated, and pre- vs. posttreatment testing. Both before and after treatment, subjects responded most slowly and least accurately to letter-matching. Bilateral presentation of stimuli resulted in faster and more accurate responses, except on shape-matching. Neuroleptic treatment improved speed and accuracy overall, though not under certain task conditions. Results accorded more with an impairment in verbal processing and interhemispheric coordination than with a specific left-hemispheric deficit in schizophrenia.

Auditory attention in process and reactive schizophrenia.

The present data indicate that, based on level of premorbid adjustment (process-reactive), schizophrenic subjects differ in auditory attention processes. Generally speaking, poor premorbid adjustment is associated with more attention dysfunction. Results also indicate that attentional deficits improve for all schizophrenic subjects after a 28-day period of neuroleptic therapy.
