Imaginal correlates of self-reported fear and avoidance behavior

Two analogue studies explored the relationship between the content of subjects' imagery and both behavioral avoidance and self-reports of fear. In the first study, reports of aversive imagery in a fearful situation were much more frequent among high- as compared to low-avoidance subjects. Reports of aversive imagery were found significantly associated with both fear and avoidance behavior. In the second study, findings were extended, indicating that imagery content is associated with fear and avoidance when subjects imagine themselves in a fearful situation as well as when they are actually in one. This suggested some degree of functional equivalence between imagined and real situations. However, no relationship was found between image clarity and either fear or avoidance. Since imagery appears to play an important role in mediating fearful behavior, manipulation of imagery might serve as an effective treatment strategy.     

How effective are our marriage ministries? A critical survey

Since the introduction of marriage and family counseling into some seminary curricula thirty years ago, the majority of clergy have developed premarital counseling as a part of their marriage ministries, and educational committees have established marriage and family courses in church school programs. Two questionnaires, used in three clergy conferences, provide data for a critical survey of representative clergy involved in ministry to marriage. Analysis of the data and interviews with a continuing education director and a marriage counseling trainer provide reasons why clergy may not be fully qualified and, therefore, may be only partially effective as marriage counselors. The kinds of educational experience necessary for ministers to become more effective in marriage ministry are examined. Finally, the minister's role in marriage in a secular society is interpreted as undergoing a shift for which many clergy are unprepared.     

Effects of using self-recording and self-observation in reducing disruptive behavior

In an attempt to reduce the levels of disruptive behavior, six participants in a school for students with behavior disorders were shown edited videotapes depicting themselves appropriately engaged in classroom activities. The participants were first exposed to a training condition in which both appropriate and inappropriate behaviors of a peer were either observed or observed and recorded. In the intervention condition, the participants either self-observed and self-recorded their behaviors from videotape or simply observed themselves on videotape. The results showed idiosyncratic effects across both conditions. Measures of treatment integrity and treatment acceptability were also conducted. The results of this study are compared with similar research investigating self-observation interventions.     

Hyperactivity and the Fragile X Syndrome

Workers who have claimed an association between Fragile X [fra(x)] Syndrome and Hyperactivity and aggressive behavior have done so despite the lack of controlled studies using standard diagnostic criteria. Accordingly, we provided a controlled test of the hypothesis that individuals with the fra(x) Syndrome are more hyperactive and have more symptoms of aggression than other mentally retarded individuals. The test formed part of a study to assess autistic behavior in fra(x) individuals. A sample of fra(x) individuals was obtained from the register of a clinical genetics unit and individually matched for age, sex, and IQ with mentally retarded individuals selected from assessment centres. Fortyfive pairs of fra(x) cases and control individuals were compared on criteria which reflected DSM-III concepts of hyperactivity and on criteria reflecting aggressive behavior. The comparison failed to find a higher prevalence of these symptoms in the fra(x) group. An analysis of the study's statistical power suggested that it is unlikely that the investigation failed to detect a large to medium difference between fra(x) individuals and control individuals in the symptoms investigated.     

The sampling of critical,unshared information in decision-making groups: the role of an informed minority

A collective information sampling model and observations of discussion content suggest that decision-making groups often fail to disseminate unshared information. This paper examines the role that a fully-informed minority may play in facilitating the sampling and consideration of unshared information. University students read a mystery and then met in four-person groups to discuss the case. When critical clues were unshared among three members before discussion, a fully informed fourth member (informed minority) promoted the discussion of these critical clues when participants thought the mystery had a demonstrably correct answer (solve set) but not when they thought the clue may have been insufficient to solve definitively the case (judge set). None the less, under both solve and judge sets, the informed minority increased the likelihood that the group would identify the correct suspect. Social combination, information sampling, and minority influence interpretations of the results are discussed. © 1998 John Wiley & Sons, Ltd.     

Predictability of chronic intermittent stress: effects on sympathetic-adrenal medullary responses of laboratory rats

This experiment involved an examination of sympathetic-adrenal medullary responses of laboratory rats following exposure to chronic intermittent stress. Animals were assigned at random to one of three groups: (i) controls, handled briefly each day; (ii) restraint stress (RS), restrained for 30 min per day; or (iii) variable stress (VS), exposure to restraint, cold swim, or intermittent footshock during one of five time periods each day. On the 26th day, rats were prepared with chronic tail artery catheters for remote sampling of blood and direct measurement of mean arterial pressure and heart rate. On Day 28, rats of each group were exposed to 30 min of restraint stress and timed blood samples were collected and later analyzed for content of norepinephrine (NE) and epinephrine (EPI). VS rats gained significantly less body weight compared to control and RS rats. Basal measures of blood pressure and heart rate and of plasma NE and EPI were comparable for rats of the three groups. The plasma catecholamine responses to restraint stress on Day 28 were significantly reduced in RS and VS rats compared to first-time stressed controls. These findings suggest that predictability of the type of stressor and the time of its occurrence does not influence the pattern of diminished sympathetic-adrenal medullary responses of animals exposed to chronic intermittent stress.
