Cognitive Behavior Therapy With Body Image Exposure for Bulimia Nervosa: A Case Example

Cognitive behavior therapy (CBT) is an effective treatment for bulimia nervosa (BN). However, among patients with BN, symptom improvement is more pronounced for behavioral eating symptoms (i.e., bingeing and purging) than for body image disturbance, and the persistence of body image disturbance is associated with relapse. The need for more effective body image interventions led to the development of mirror exposure, which focuses on encouraging patients to view themselves in a holistic, nonjudgmental, mindful fashion. Behavioral manifestations of body image disturbance—body checking and avoidance—are also targeted in order to reduce and eliminate such behaviors and their associated preoccupation and distress. A preliminary trial of Body Image Exposure has shown promise, but it has not yet been tested in the context of CBT for BN. The case of “Sara” illustrates the application of this targeted treatment for body image disturbance. Central clinical issues around the perceptual, cognitive, and behavioral components of body image are delineated as they arose in treatment, as are issues of motivation and compliance. Treatment was associated with improvement in eating symptoms, body image, and mood.     

Adult age differences in the ability to mentally transform object and body stimuli

Cognitive neuroscience literature suggests a strong dissociation between the ability to mentally transform object and body stimuli (Hegarty & Waller, 2004). However, little is known about how this ability changes with age. This dissociation was explored in 20 younger (19-24 years) and 20 older (65-87 years) adults. Mental rotation of object stimuli was demonstrated for both age groups, suggesting that the neuro-cognitive network involved with performing (object-based) mental transformations is relatively preserved in older age. Compared to young adults, older adults displayed the greatest decline in performance efficiency for the whole-body task. The authors propose that an age-related decline in the integrity of body-schema information may account for this change.     

Acknowledging the skeletons in our closet: the effect of group affirmation on collective guilt, collective shame, and reparatory attitudes

Just as with threats to personal identity, people defend against social identity threats. In the context of intergroup injustice, such defensiveness undercuts collective guilt and its prosocial consequences. The current research examines whether group affirmation allows perpetrator groups to disarm threat without undermining guilt. In Study 1, men accepted greater guilt for gender inequality after affirming the ingroup. Given the distinction between collective guilt and collective shame, Studies 2-4 assessed both emotions and revealed that Canadians accepted greater guilt and shame over the mistreatment of Aboriginals following group affirmation. In Study 3, group affirmation also moderated the relation of each emotion with reparatory attitudes. When controlling for each other, collective shame predicted compensation in a nonaffirmation control condition whereas guilt predicted compensation once identity threat had been disarmed by group affirmation. In Study 4, the effect of group affirmation on the collective emotions was mediated by defensive appraisals of the injustice.     

The Effects of Atropine and Adrenergic Antagonists on Behavioral Arousal in Rats

Two experiments investigated the mechanism for changes in measures of behavioral arousal inhibition in rats following administration of atropine. In Experiment 1, 40-day-old rats were given administrations of atropine sulfate, the α-, β-adrenergic blocker labetalol, or both. The drugs, either alone or in combination, increased transport response intensity, whereas both together increased dorsal immobility durations. In Experiment 2, rats were given atropine, the β-adrenergic antagonist propranolol, the α-adrenergic antagonist phentolamine, or a combination of two of the drugs. Propranolol blocked atropine-induced increases in transport response, and phentolamine was without effect. Phentolamine, when combined with atropine, increased dorsal immobility durations. Results are discussed with respect to aspects common to both transport response and dorsal immobility.     

Caffeine enhances the physiological response to occupational stress in medical students

Caffeine (3.3 mg/kg) was tested against a placebo in 20 male medical students during periods of low (no exams) versus high (final exams) work stress. On each of 8 test days, heart rate and blood pressure were measured at baseline and over a 40-min postdrug interval; immediately afterward, blood was drawn to test plasma cortisol and serum lipid concentrations. Exams increased heart rate (p less than .005) and systolic blood pressure (p less than .02). Caffeine decreased heart rate (p less than .0001) and increased systolic blood pressure (p less than .005), diastolic blood pressure (p less than .0001), plasma cortisol levels (p less than .01), and serum cholesterol levels (p less than .02). Caffeine effects were additive with those of exams, and together they increased the number of men showing systolic blood pressures in the borderline hypertensive range. Thus, caffeine use during periods of increased occupational stress may enhance the cumulative stress response.     

Gender Differences in Reactions to the Sexualization of Athletes

Participants rated a series of photographs that depicted well-known male and female athletes in a sexualized fashion or not. In general, sexualized targets were perceived as more attractive but as less competent than non-sexualized targets, and for ratings of competence, sexualization effects were greater for female targets. Sexualization had no effects on women’s perceptions of the competence of male targets, whereas for men, sexualization affected their perceptions of the competence of both male and female targets, although the influence of sexualization was stronger for female targets than it was for male targets. These findings suggest that the gender of the target and of the perceiver needs to be considered when evaluating the influences of sexualization. The implications of these findings are discussed within the context of objectification theory, which has focused on the objectification of women by women.
