Voluntary control of two lateralized conscious states: validation by electrical and behavioral studies.

A subject is described who can voluntarily select and hold either of two qualitatively different states of consciousness. Evidence is presented which confirmed differential left or right hemisphere dominance in each state. Asymmetries of EEG alpha and task performance scores indicated a state-dependent shift in functional lateralization. Evoked response studies showed directional changes in rate of interhemispheric transmission correlated with state-related hemisphere dominance. These findings demonstrated that capability for voluntary endogenous control of cerebral dominance under natural conditions.

Psychological characteristics of males with secondary erectile failure.

This study was designed to obtain objective data on the personality profiles of two groups of males with a primary complaint of erectile failure and compare them to a group of psychiatric patients unselected for sexual dysfunction and to a sexually "normal" control group. Utilizing the Eysenck Personality Inventory, the Institute of Personality and Ability Testing Anxiety Scale, Symptom Checklist, and the Minnesota Multiphasic Personality Inventory, it was determined that males applying to a university/county hospital sex-dysfunction clinic appeared similar to patients seen in the same clinic who were unselected for sex dysfunction and more psychologically disturbed than patients with the same complaint applying for treatment at a private clinic. All three groups showed more psychopathology than sexually normal males. The implications of these findings 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.

Lithium effects on normal subjects. Relationships to plasma and RBC lithium levels.

15 normal subjects took lithium carbonate for 10 days in dosage sufficient to attain plasma lithium concentrations in the range of 0.7-1.4 mEg/l. Periodic blood specimens were analyzed for both plasma and RBC lithium. Subjects completed Profile of Mood States questionnaires every other day, and listed side effects. Just prior to beginning and ending the lithium trial, 10 subjects completed three tests of psychomotor function. Results indicate that such a course of lithium in normals induces dysphoric mood change and psychomotor slowing, without significant relationship to either plasma or RBC lithium concentrations.

Patients' attitudes toward behavior therapy and psychotherapy.

A questionnaire survey of 50 patients treated by behavior therapy or short-term, analytically oriented psychotherapy revealed that both groups, as well as those patients who improved the most, placed a high value on insight, the patient-therapist relationship, catharsis, and trust. The findings suggest that behavior therapy patients tend to place more emphasis than do their therapists on factors that have traditionally been thought important in analytic psychotherapy.

Behavioural treatment of orgasmic dysfunction: a controlled study.

Twenty-two anorgasmic women received 20 sessions of a multiple-technique behavioural therapy. The design included blind ratings by two independent assessors, multiple assessment instruments, and a waiting list control group. Treatment was significantly better than no treatment in terms of: (1) the percentage of patients experiencing orgasm during at least 50 per cent of sexual relations; (2) the percentage of women reporting satisfactory sexual relations at least 50 per cent of the time; (3) patients' ratings of positive reactions to various sexual behaviours; and (4) assessors' global clinical ratings. Significant improvement was also noted on the MMPI, IPAT, and Symptom Check List. Improvement was maintained at a follow-up average 9 months later. These results support the impression that a behavioural approach offers much promise in treating female orgasmic dysfunction.

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.

Differences between behavior therapists and psychotherapists.

Patient-therapist interaction patterns of three experienced behavior therapists and three matched analytically oriented therapists were compared. Each therapist saw ten patients in short-term individual therapy. The more active behavior therapists dominated the conversation in terms of speech time, more frequently offered explicit advice and instructions, gave more direct information, presented their own value judgments, and exerted greater control over the content of the interaction than did psychotherapists. Although both groups provided a warm and accepting atmosphere, behavior therapists showed higher levels of accurate empathy, interpersonal contact, and therapist self-congruence. Patients viewed behavior therapists as more authoritarian and believed that psychotherapists encourage greater independence. It was concluded that the two therapy approaches to patients were consistent with theoretical models of each.
