Psychiatry, religious conversion, and medical ethics.

The interface between religion, psychiatry, and ethics is often a locus for considerable controversy. This article focuses on the response of American psychiatry to religious nonconformism, and to religious conversion generally. At issue is the societal pressure against unpopular religious movements. The author argues for an ethic that conserves the freedom of religious conscience, and that guards against inquisitions in the guise of medical expertise and nosology.     

Cerebral lateralization in individuals diagnosed as autistic in early childhood

Early infantile autism was found to be associated with an atypical pattern of cerebral lateralization. Based on EEG measures of hemispheric activation during cognitive processing, it was found that 7 of the 10 autistic individuals tested showed a pattern of hemispheric specialization rarely seen in the normal population; namely, a “reversal” in lateralization reflective of a lack of left-hemisphere specialization for linguistic functions. Furthermore, the autistic individuals' pattern of cognitive strengths and weakness is suggestive of a selective impairment of the left cerebral hemisphere.     

Fat,Four-Eyed,and Female: Stereotypes of Obesity,Glasses, and Gender1

In a between-subjects design, 46 male and 101 female Australian university students rated a target person described as male or female, overweight or average weight, and wearing glasses or not, on twelve 7-point rating scales. As predicted, a negative stereotype of the overweight person and a complex one of the person with glasses were found. However, there was no significant effect of sex of target except on the ratings of masculine and feminine and no interaction of sex of target with either the glasses or obesity variables. Nor did sex of subject influence the ratings. The results suggest that, although stereotypes of obesity and glasses do exist, they may be as severe for men as for women.     

The role of imagery in the representation of linear orderings

Two experiments were carried out to investigate whether visual imagery was used in representing transitive linear ordering relationships. Subjects were presented with passages describing either a linear ordering or a set inclusion relationship, while being subjected to either visual or verbal interference. Performance was tested by asking subjects to judge the truth or falsity of statements concerning both the information presented in the passages and inferences that could be drawn from this information. In neither experiment was there any evidence for the linear ordering material being selectively disrupted by the visual interference task, as would have been predicted by the imagery theory. Thus it is concluded that linear orderings are probably not represented as visual images.     

Perceived control in continuous loud noise

The effects of two types of perceived control were assessed for performance during and following exposure to continuous loud noise at 90 dBC. Subjects performed a tracking task during exposure and the Stroop test in the period following exposure. Control could be effected either (1) by attenuating the intensity of the noise or (2) by reducing the difficulty of the tracking task. In both cases subjects were encouraged not to exercise control. Performance in treatments involving loud (90 dBC) and soft (55 dBC) noise served as baseline conditions. Perceived control of task difficulty accentuated the tendency for root-mean-square error to rise during the tracking task. There were no significant effects of noise intensi ty on tracking performance. Loud noise reduced the incidence of errors in the Stroop test but perceived control failed to influence this effect. The results are discussed in terms of the generality of perceived control phenomena.     

Auditory adaptation to gradual rise or fall in intensity of a tone

The auditory system adapts to gradual changes of intensity. After listening to a gradually loudening (or softening) tone, a steady test tone appeared to be growing gradually softer (or louder). “Tuning curves” for these aftereffects were measured by adapting to one audio frequency and testing at another. Softening tones produced larger aftereffects, which were more sharply tuned for audiofrequency, than did loudening tones.     

EVALUATION OF BIOFEEDBACK IN THE TREATMENT OF BORDERLINE ESSENTIAL HYPERTENSION1

Direct biofeedback of blood pressure was compared with frontal EMG biofeedback and with self-instructed relaxation for the treatment of essential hypertension in a controlled group outcome study. Patients were followed up for four months after the end of treatment. Generalization of treatment effects was assessed through pre- and posttreatment measurements of blood pressure under clinical conditions in a physician's office. There were no significant reductions in diastolic blood pressure. The systolic blood pressure (SBP) of the patients receiving blood pressure biofeedback decreased 8.1 mm mercury (p = 0.07) and the SBP of the patients in the relaxation condition decreased 9.5 mm mercury (p = 0.05). In the generalization measures, there were significant reductions in SBP for the relaxation group. The results are discussed in terms of the general lack of replicability within the area of biofeedback treatment of hypertension.     

Guruitis: Epidemiology,causes, symptoms,and remediation

This article summarizes the current understanding of the condition known asguruitis. A general picture of the etiology, prognosis, and treatment of this illness is presented. Guruitis emerges as a multifactorial, nonlethal, widespread professional disease. The illness essentially involves the idealization of some professional figure who may have varying degrees of closeness with a larger theoretical base or orientation, but whose personal attributes interact with those of the potential victim, thus producing onset of the disease.     

The role of attribution in the experience of crowding

The theory that the subjective experience of crowding results from an attribution of arousal process was examined. Specifically, it was predicted that subjects who were aroused by having their personal space violated would experience less crowding if they were led to believe that some other environmental factor was responsible for the arousal. Groups of subjects were placed in a room in which their personal space was either violated or not violated. Some subjects were told that either an arousing or a relaxing subliminal noise would be played into the room. (Actually there was no noise.) Other subjects were told nothing about subliminal noise. The subjects worked on a number of tasks and were then asked to report how crowded they felt. The noise manipulation had no effect on subjects' performance nor on feelings of crowdedness when their personal space was not being violated. However, when there was a violation of personal space, subjects who felt the noise would arouse them reported being less crowded and performed better than subjects in the relaxing noise or no explanation conditions. It was suggested that subjects attributed their arousal to the “arousing noise” and hence felt less crowded.
