Regional cerebral blood flow response to recognition memory versus semantic classification tasks

Two randomly assigned groups, N = 7 each, of neurologically normal patients were composed. One group, RM, had regional cerebral blood flow measurements during a recognition memory probe test; the other group, SC, had rCBF measurements during a semantic classification task, using the same stimulus and response features as the RM task. Thus, the groups differed only in the cognitive instruction they were executing. The RM group showed a significantly lower change from resting baseline to activation, in mean left hemisphere initial slope index, than did the SC group. The RM group, but not the SC group, showed a significant inverse correlation between occipital flow and accuracy of memory performance as indicated by d′. Correlations between age and hemispheric initial slope index, and between homologous left and right hemisphere sites, were also described. The results are considered to support an anatomical basis for the distinction between episodic and semantic memory and to suggest that occipital flow may diminish with accurate memory performance because of an upstream demand of blood in the medial temporal lobes.     

Controlled comparison of aversive therapy and covert sensitization in compulsive homosexuality

Ethical objections to the use of behaviour therapy in homosexuality are discussed. It is pointed out that these objections were often based on a limited view of the aims of the therapy. The need for evaluating such therapy, as it is currently used, is elaborated.Twenty subjects requesting behaviour therapy to reduce compulsive homosexual urges were randomly allocated, half to receive aversive therapy using electric shocks and half to receive covert sensitization. Both groups were studied for one year. There was no consistent trend for one therapy to be more effective than the other in reducing the strength of compulsive homosexual urges, and the response to both was similar to that reported in previous studies. It was considered that aversive therapies in homosexuality do not act by establishing a conditioned aversion, nor by altering the subjects' sexual orientation. They reduce aversive arousal produced by behaviour completion mechanisms when subjects attempt to refrain from homosexual behaviour in response to stimuli which have repeatedly provoked such behaviour in the past.     

Manager behavior in a social context: the impact of impression management on attributions and disciplinary actions

Two experimental studies were run to test the effects of subordinate impression management on the appraisals and responses of a manager, following an incident of poor performance. Two common impression management tactics, accounts and apologies, were manipulated in each of the studies. Subjects in both studies were experienced nursing supervisors. On the basis of the "discounting effect" reported in the attributional literature it was hypothesized that accounts of external causes for poor performance, i.e., excuses, would lead subjects to (1) attribute less responsibility to the subordinate, (2) be less personal in their responses, and (3) be less punitive in their responses. Apologies, because of their "equity restoration" effects, were expected to influence subjects' disciplinary responses to the poor performance, without necessarily affecting their attributions of responsibility. Experiment 1. which employed written stimulus materials and a repeated-measures design, provided strong support for all hypotheses. Experiment 2. which employed a film stimulus and between-subjects design, provided strong support for the accounts hypotheses but only minimal support for the apology hypotheses. The results highlight the importance of social information cues in the appraisal of performance.     

Asia-Pacific prevention research. CHallenges, opportunities, and implementation

An effort is underway in the Asia-Pacific region to carry out multidisciplinary prevention research, with an emphasis on understanding health-related behaviors. In partnerships with the U.S. Centers for Disease Control, the U.S. Public Health Service, international health agencies, governments, and universities in the region, researchers at the University of Hawaii are pursuing a paradigm for international, multicultural prevention research in the field of health promotion and disease prevention. An integrated framework for guiding a program of research is discussed along with several factors that present challenges to the conduct of prevention research in the Asia-Pacific region.     

Occupation and handedness: an examination of architects and mail survey biases

Handedness among architects was determined by mail survey. Contrary to previous reports, no evidence was found of an excess of left-handers among a sample of 236 fully qualified male architects and 78 male architectural students. A second study examined whether the use of mail surveys systematically biases the returns of handedness questionnaires. For this, questionnaires were sent to 1,017 university students. No evidence was found for a bias amongst those who did and did not reply to the initial questionnaire. These results strengthen the findings of the first study.     

Predicting the Everyday Life Events of Older Adults

Predicting the everyday life events of people is a relatively unexplored topic, although several major theoretical approaches deal with related issues. The dispositional approach would assign a causal role to personality, while the situational approach would locate causation in the person's environment. Variations on these two extreme themes invoke an interactionist interpretation. Beyond this, a genuinely transactional approach focuses on the enduring person-environment relationship established as people deal with major and everyday life events. This study investigated a wide range of predictors of daily positive, negative, and ill-health events over time in a sample of 206 older adults. Results showed that personality variables played only a minor role in predicting daily events, although an interaction between extraversion and social network size was significant. Background demographic variables and the major stressors of recent conjugal bereavement and physical disability played a role in daily event occurrences. Overall, the strongest degree of predictability of events came from the events themselves: The high degree of event stability over time indicated the value of a genuinely transactional model in understanding the occurrence of everyday events.     

New assessments of weight-related body image derived from extant instruments

A study of 79 female college students examined the reliability and validity of two new size/weight-related measures of body image. The Body-size Appraisal Scale and the Overweight Preoccupation Scale were derived from existing instruments. Analyses supported the internal consistency and 2-wk. test-retest reliability of both new scales. Correlations of scores on each scale with measures of anxiety about being fat, negative body-image affect and avoidance, restrained and bulimic eating, and depression support their concurrent and construct validity. Scores on the Overweight Preoccupation Scale were also related to the extent of investment in physical appearance. Regression analyses indicated that each new scale could be predicted from several other conceptually relevant body-image attitudes, even after actual body weight was controlled.
