Two types of conditioning in psychotics and normals.

The conditionality of 2 groups of schizophrenics (chronic paranoids and chronic nonparanoids) and a normal (male nurses) was tested via 2 methods of conditioning: visual (stimulus)—eyelid (response), and auditory (stimulus)—handpress (response). The results indicated no difference between the groups re: eyelid conditioning, but the paranoid group took significantly longer to condition on the verbal procedure. Suggested reasons for the results are discussed, and the results are compared with that of previous research. 18 refs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
