Stuck in the middle: the many moral challenges with bariatric surgery

Bariatric surgery is effective on short- and medium-term weight loss, reduction of comorbidities, and overall mortality. A large and increasing portion of the population is eligible for bariatric surgery, which increases instant health care costs. A review of the literature identifies a series of ethical challenges: unjust distribution of bariatric surgery, autonomy and informed consent, classification of obesity and selecting assessment endpoints, prejudice among health professionals, intervention in people's life-world, and medicalization of appearance. Bariatric surgery is particularly interesting because it uses surgical methods to modify healthy organs, is not curative, but offers symptoms relief for a condition that it is considered to result from lack of self-control and is subject to significant prejudice. Taking the reviewed ethical issues into account is important when meeting persons eligible for bariatric surgery, as well as in the assessment of and decision making on surgery for obesity.     

The tight coupling between category and causal learning

The main goal of the present research was to demonstrate the interaction between category and causal induction in causal model learning. We used a two-phase learning procedure in which learners were presented with learning input referring to two interconnected causal relations forming a causal chain (Experiment 1) or a common-cause model (Experiments 2a, b). One of the three events (i.e., the intermediate event of the chain, or the common cause) was presented as a set of uncategorized exemplars. Although participants were not provided with any feedback about category labels, they tended to induce categories in the first phase that maximized the predictability of their causes or effects. In the second causal learning phase, participants had the choice between transferring the newly learned categories from the first phase at the cost of suboptimal predictions, or they could induce a new set of optimally predictive categories for the second causal relation, but at the cost of proliferating different category schemes for the same set of events. It turned out that in all three experiments learners tended to transfer the categories entailed by the first causal relation to the second causal relation.     

The role of occlusion cues in apparent motion

Classical apparent motion stimuli exhibit an inherent ambiguity with respect to the onsets and offsets of the stimulus elements. Sigman and Rock (1974, Perception 3 9-28) presented evidence suggesting that occlusion cues are used to resolve this ambiguity. We present results from experiments designed to further test predictions of this hypothesis. As expected, we found that the apparent motion of a target stimulus is suppressed when a 'moving' occluder is positioned such that it rationalises the onsets and offsets of the stimulus elements constituting the target. Somewhat unexpectedly, though, we also observed a slight tendency for motion suppression under conditions where the target was only partially occluded. The expected motion suppression occurred both with solid occluders and purely virtual Kanizsa-like occluders, although it was not always observed in the latter case. Motion suppression was found to occur over a wide range of stimulus onset asynchronies. Finally, we used binocular disparity cues to test the occlusion account of the motion suppression phenomenon against an alternative explanation in terms of attentional factors. The results are in clear favour of the occlusion account.     

How long does it last? Prior victimization from workplace bullying moderates the relationship between daily exposure to negative acts and subsequent depressed mood

The aim of the present study was to examine the relationships between daily exposure to negative acts and depressed mood on the same day and on the days following the exposure, and to test the hypothesis that these relationships would be stronger among those who have recently gone through a process of victimization from workplace bullying. The sample comprised 110 naval cadets participating in two different eleven-week tall ship voyages from Northern Europe to North America. Victimization from workplace bullying the last six months was measured one day prior to the voyages. Exposure to negative acts and depressed mood was measured daily during the first 33 consecutive days of the voyages. The results of multilevel modelling indicated that exposure to negative acts was related to higher levels of depressed mood on the same day as the exposure among all cadets, regardless of victimization status. However, exposure to negative acts predicted higher levels of depressed mood one and two days following the exposure among victims only. The theoretical and practical implications of these findings are discussed.     

A two-week monitoring of self-reported arousal, worry and attribution among persons with annoyance attributed to electrical equipment and smells

Non-patients attributing annoyance to either smells (smell annoyed; SA, n= 29) or electrical equipment (electrically annoyed; EA, n= 17), or both (generally annoyed; GA, n= 38), were monitored for 2 weeks through daily self-ratings of arousal (stress), sleep disturbances, health complaints, worry about hypersensitivity reactions, avoidance behaviors, and attributions of health complaints to electrical equipment and smells. In parallel, a demographically matched reference group was followed (n= 56). GA persons reported higher arousal (stress), more subjective health complaints, and more sleep disturbances than the other groups. About 60% in the GA and EA groups reported intentional avoidance behavior, compared to 31% in the SA group and 2% of the referents. Worry and attribution to environmental factors was also more frequent among GA persons than in the other groups. Thus, even at sub-clinical levels, environmental annoyance generalized to several triggers seems to be associated with behaviors commonly observed among patients with idiopathic environmental intolerance.     

Prevalence and correlates of gambling among 16 to 19-year-old adolescents in Norway

There is evidence that young people are at high risk of developing gambling disorders. The prevalence and correlates of gambling among youth therefore merit closer study. During spring 2004, a sample of 1,351 boys and girls (aged 16–19 years) from 151 high-school classes (clusters) participated in an internet survey about gambling. The response rate was 69.8%. The instruments used in the survey were the Hospital Anxiety and Depression Scale, the Alcohol Use Disorders Identification Test and the Massachusetts Adolescent Gambling Screen, in addition to questions about demography. Controlling for the design effect, the estimated prevalence rate was 2.5% for pathological gambling and 1.9% for problem gambling. In all, 7.3% of the boys and 0.6% of the girls fulfilled the criteria for pathological or problem gambling. The results of item analysis of the DSM-IV subscale of MAGS provide support for differential item functioning between boys and girls. A multiple logistic regression analysis revealed that gender (male: OR = 9.09), depression (OR = 9.23), alcohol abuse (OR = 3.62), and dissociation (OR = 1.96) were related to problem and pathological gambling. These results support the view that gambling disorders are best understood as part of an addictive behavior spectrum ( Jacobs, 2000 ).     

Rorschach Variables and Big Five Scales as Predictors of Military Training Completion: A Replication Study of the Selection of Candidates to the Naval Special Forces in Norway

Thirty-nine undergraduate male college students drew five figures — an automobile, a clothed male, a clothed female, a nude male, a nude female — while a continuous record of their GSR activation was obtained. Analysis of GSR data showed that activation differed significantly from the relatively neutral but equally difficult drawing (i.e., the automobile). Nude figure drawings differed significantly in GSR activation from clothed figure drawings. GSR responses of largest amplitude showed significant shifts from the largest responses occurring to secondary sexual bodily areas in the clothed drawings to primary sexual areas in the nude drawings. Only the clothed male and the nude male drawings differed significantly between groups judged different in psychosexual adjustment.     

Exploring the relationships between maternal and child metacognitions and child anxiety

Research has shown that anxiety may be transmitted through verbal information pathways, for example, when parents share their anxious cognitions with their child. Less is known about the influence of parental metacognitions, that is, beliefs regarding thoughts, on child anxiety. We explored the relations between metacognitions in mothers and their children and anxiety in the children. Our study included 111 non‐clinical children aged 8 to 12 years and their mothers. Children rated their metacognitions, worry and anxiety, and mothers rated their metacognitions. Results indicated agreement between maternal and child metacognitions. Maternal metacognitions were positively associated with children's anxiety symptoms and worry, and this relation was mediated by the children's metacognitions. Our results warrant further examination of the role of parental metacognitions in child anxiety.     

Infantile defences in parent‐infant psychotherapy: The example of gaze avoidance

Findings from parent‐infant observational research have stimulated the development of intersubjective models of psychotherapeutic action. These models have brought out the infant as an interactive partner with the parent. Conversely, interest in describing the individual psyche of the baby has decreased, especially the unconscious levels of his/her experiences and representations. In parallel, clinicians and researchers have been less prone to apply classical psychoanalytic concepts when describing the internal world of the infant. The author argues that this is inconsistent with the fact that psychoanalytic theory, from its inception, was founded on speculations of the infant's mind. He investigates one such concept from classical theory; the defence. Specifically, he investigates if selective gaze avoidance in young babies may be described as a defence or even a defence mechanism. The investigation links with Selma Fraiberg's discussion of the phenomenon and also with Freud's conception of defence. The author also compares his views on the baby as a subject with those suggested by infant researchers, for example, Stern and Beebe. The discussion is illustrated by vignettes from a psychoanalytic therapy with a 3 month‐old girl and her mother.
