Modification of Two Operants (Verbal and Non-Verbal) of Near-Mute Schizophrenics Using Reinforcement and Modeling Procedures.
Major variables related to reinstatement of speech in hospitalized mute and near-mute schizophrenics were isolated and investigated. The study consisted of four parts: (1) verbal conditioning of mute and near-mute chronic schizophrenics using four experimental groups and two control groups, (2) four extra-laboratory measures for testing generalization from the experimental setting to the ward, (3) continuation of verbal conditioning with the same, different, or additional experimental procedures systematically applied to subjects in various probing strategies, and (4) conditioning a lever-pull response. Although the first ten verbal conditioning sessions indicated no significant group differences, useful information regarding the effects of the different procedures upon producing verbal behavior in individual subjects was obtained. The four extra-laboratory measures did not indicate generalization of the subjects' verbal behavior from the laboratory situation to the ward. The lever-pull experiment showed that the same stimulus which had not been a reinforcer in the verbal conditioning experiment served as a reinforcer for the lever-pull response. Increases in the verbal outputs of eight subjects indicated that some combinations of experimental treatments might be considered by therapists engaged in reinstating or developing verbal behavior.
