Efficacy of a brief group psychoeducational intervention for bulimia nervosa

This study compared a brief group treatment that was designed to be purely educational (ED) with a longer course of individual cognitive-behavioural (CB) therapy intended to represent more standard clinical care. Participants were 65 women who sought treatment at Toronto General Hospital, met DSM-III criteria for bulimia nervosa at a normal weight and reported vomiting at least twice weekly. Results indicated that the CB treatment, as expected, was generally more effective than the ED intervention, but on several important outcome indices both treatments appeared to be equally effective for the healthiest 25-45% of the sample. The more intensive individual CB treatment was associated with greater improvement in patients who were more severely symptomatic. However, the ED intervention proved significantly more cost-effective and it was suggested that a sequential treatment program might achieve the superior benefits associated with the longer individual CB treatment at a reduced cost.     

The repressor personality and avoidant information processing: A dichotic listening study

The present research was designed to investigate the proposition that repressors, operationally defined by the conjunction of low anxiety and high defensiveness, are particularly adept at avoiding the processing of information when motivated to do so. Four groups of participants (nondefensive-low anxious, high anxious, repressors, and defensive-high anxious) were administered a dichotic listening task involving neutral or negative affective words presented in the unattended ear. Participants shadowed the material presented to the attended ear and simultaneously responded to a probe task presented on a video monitor. Results revealed that repressors made significantly fewer shadowing errors than high anxious and defensive-high anxious participants and marginally significantly fewer shadowing errors than low anxious participants for both neutral and negative words. High anxious participants, however, were later able to recognize the negative words that had been presented to the unattended ear at well above chance levels, whereas the recognition memory of repressors for such negative unattended words was at chance levels. In addition, repressors' responses to a postexperiment questionnaire indicated a significantly greater number of distracting thoughts during the experiment relative to other participants. Repressors, it seems, are indeed skillful at avoidant information processing and this capacity may well be related to the emotional memory deficits they have displayed in previous research.     

Remaking the She-Devil: A Critical Look at Feminist Approaches to Beauty

Cosmetic surgery provides a problematic case for feminist theorizing about femininity and women's relationship with their bodies. Feminist accounts of femininity and beauty are unable to explain cosmetic surgery without undermining the women who opt for it. I argue that cosmetic surgery may have less to do with beauty and more to do with being ordinary, taking one's life into one's own hands, and determining how much suffering is fair.     

Suppressor effects in the relations of psychological variables to resting blood pressure

The role of suppressor effects in obscuring the relation of psychological variables and blood pressure was studied. Forty-five nonmedicated patients in a family practice rated themselves relative to their peers on a series of characteristics. Two of these, trapped and lonely, exhibited marked suppressor effects in their relationship with each other and resting blood pressure. Self-ratings of lonely exhibited a moderately strong positive association with ratings of trapped (r = .63) while only ratings of lonely showed a significant correlation with resting systolic blood pressure (r = .31). Yet when the suppressor effects of the ratings on feeling lonely were removed in the regression analyses, the ratings on feeling trapped showed a significant positive association with resting systolic pressure (r = .42). Similarly, while neither ratings on feeling lonely or on feeling trapped showed separately a significant association with resting diastolic pressure, when suppressor effects were removed in the regression analyses, the ratings of trapped were significantly associated with diastolic pressure in a positive direction (r = .34) and ratings of lonely were significantly associated in a negative direction (r = .33). The significance of this specific suppressor effect and the implications of suppression for psychosomatic research are discussed.     

Motivation and learning: Neurophysiological mechanisms in a “model” system

The neurophysiological mechanisms underlying behavioral motivation and associative learning are described in an invertebrate “model” system, the carnivorous marine mollusc Pleurobranchaea. Feeding motivation can be controlled via nutritional history and is represented centrally in the feeding motor network as a change in the balance of synaptic excitation and inhibition at the level of interneurons that initiate feeding behavior, i.e., feeding “command” interneurons. Associative learning, induced by avoidance conditioning of feeding behavior, manifests identically at the level of the command interneurons, but is distinguished from non-associative motivational changes by processes that occur in identified neurons and pathways presynaptic to the command interneurons. Motivation and learning are therefore linked mechanistically by convergent neurophysiological mechanisms at the level of central neurons that initiate behavior.     

Perceptions of unresponsive others: Attributions,attraction, understandability,and memory of their utterances

Analyses of the rules governing conversation have frequently pointed to the existence of a rule dictating that responses to others' communications should be relevant. Unfortunately, there have been few systematic theoretical analyses of the consequences of violations of the response relevance rule. The present research was designed to extend our previous analyses of the consequences of responsiveness in dyadic interaction to examine in detail the effects of irrelevant response on processing and retention of response content, and attributions concerning the speaker. It was argued that irrelevant responses will be processed and retained more poorly, because the preceding utterance will provide a less adequate context for their interpretation. In addition, it was argued that unresponsiveness will generally be attributed to the lack of one or more of four factors previously suggested to facilitate responsiveness: attention to the other, understanding of the preceding communication, adequate response repertoire, or motivation to be responsive—along with situational (e.g., distraction) or dispositional (e.g., incompetence) reasons for their absence. These processes were examined in the context of a political debate, in which the relevance of candidates' answers to the questions was varied. As expected, response relevance was shown to facilitate processing (as indexed by ratings of clarity and organization) and retention (both recall and recognition memory) of response content. Further, the unresponsive speaker was perceived to have less clearly understood the questions asked, to possess less knowledge of the facts and understanding of the issues concerning the questions raised, and to be less motivated to discuss the issues raised (as opposed to facilitating his self-presentational goals). Moreover, those attributions were accompanied by attributions of dispositional incompetence. Finally, the unresponsive candidate was perceived as less attractive than the responsive candidate.
