Hypothesized that a therapist's verbalizations evoke differential gsr amplitudes in his patient which are in accordance with a high to low magnitide hierarchy of confrontation, interpretation, interrogation, and reflection. Gsrs for 12 patients and their therapists in initial interviews, and 1 patient with a personality disorder of a schizoid type and his therapist over a series of 12 interviews were continuously monitored throughout the interviews. Verbatim typescripts were coded to correspond in time with the physiological data. Results indicate a correspondence between selected categories of therapist verbalizations, ordered in terms of stimulus specificity and the amplitude of his patient's autonomic arousal. A similar relationship was found between the therapist's level of autonomic arousal in response to his own categorized verbalizations. (45 ref.)
