Increased plasticity of the bodily self in eating disorders
Background: The rubber hand illusion (RHI) has been widely used to investigate the bodily self in healthy individuals. The aim of the present study was to extend the use of the RHI to examine the bodily self in eating disorders. Methods: The RHI and self-report measures of eating disorder psychopathology (EDI-3 subscales of Drive for Thinness, Bulimia, Body Dissatisfaction, Interoceptive Deficits, and Emotional Dysregulation; DASS-21; and the Self-Objectification Questionnaire) were administered to 78 individuals with an eating disorder and 61 healthy controls. Results: Individuals with an eating disorder experienced the RHI significantly more strongly than healthy controls on both perceptual (i.e., proprioceptive drift) and subjective (self-report questionnaire) measures. Furthermore, both the subjective experience of the RHI and associated proprioceptive biases were correlated with eating disorder psychopathology. Approximately 20% of the variance for embodiment of the fake hand was accounted for by eating disorder psychopathology, with interoceptive deficits and self-objectification significant predictors of embodiment. Conclusions: These results indicate that the bodily self is more plastic in people with an eating disorder. These findings may shed light on both aetiological and maintenance factors involved in eating disorders, particularly visual processing of the body, interoceptive deficits, and self-objectification
A cognitive pathway to punishment insensitivity
Individuals differ in their sensitivity to the adverse consequences of their actions, leading some to persist in maladaptive behaviors. Two pathways have been identified for this insensitivity: a motivational pathway based on excessive reward valuation and a behavioral pathway based on autonomous stimulusâresponse mechanisms. Here, we identify a third, cognitive pathway based on differences in punishment knowledge and use of that knowledge to suppress behavior. We show that distinct phenotypes of punishment sensitivity emerge from differences in what people learn about their actions. Exposed to identical punishment contingencies, some people (sensitive phenotype) form correct causal beliefs that they use to guide their behavior, successfully obtaining rewards and avoiding punishment, whereas others form incorrect but internally coherent causal beliefs that lead them to earn punishment they do not like. Incorrect causal beliefs were not inherently problematic because we show that many individuals benefit from information about why they are being punished, revaluing their actions and changing their behavior to avoid further punishment (unaware phenotype). However, one condition where incorrect causal beliefs were problematic was when punishment is infrequent. Under this condition, more individuals show punishment insensitivity and detrimental patterns of behavior that resist experience and information-driven updating, even when punishment is severe (compulsive phenotype). For these individuals, rare punishment acted as a âtrap,â inoculating maladaptive behavioral preferences against cognitive and behavioral updating
Educating through Exemplars: Alternative Paths to Virtue
This paper confronts Zagzebskiâs exemplarism with the intertwined debates over the conditions of exemplarity and the unity-disunity of the virtues, to show the advantages of a pluralistic exemplar-based approach to moral education (PEBAME). PEBAME is based on a prima facie disunitarist perspective in moral theory, which amounts to admitting both exemplarity in all respects and single-virtue exemplarity. First, we account for the advantages of PEBAME, and we show how two figures in
recent Italian history (Giorgio Perlasca and Gino Bartali) satisfy Blumâs definitions of âmoral heroâ and âmoral saintâ (1988). Then, we offer a comparative analysis of the effectiveness of heroes and saints with respect to character education, according to four criteria derived from PEBAME: admirability, virtuousness, transparency, and imitability. Finally, we conclude that both unitarist and disunitarist exemplars are fundamental to character education; this is because of the hero's superiority to the saint with respect to imitability, a fundamental feature of the exemplar for character
education
Depression in people with skin conditions: The effects of disgust and selfâcompassion
Objectives
Skin conditions can be accompanied by significant levels of depression; there is therefore a need to identify the associated psychological factors to assist with the development of appropriate interventions. This study sought to examine the effects of disgust propensity, disgust sensitivity, selfâfocused/ruminative disgust, and selfâcompassion on depression in people with skin conditions.
Design
A crossâsectional survey with followâup survey.
Methods
Dermatology outpatients (N = 147) completed selfâreport measures of disgust traits, selfâcompassion, and depression. At threeâmonth followâup, participants (N = 80) completed the depression measure again.
Results
Multiple regression analyses revealed that disgust propensity, disgust sensitivity, selfâfocused/ruminative disgust, and selfâcompassion each explained significant amounts of variance in baseline depression. Selfâcompassion also explained a significant amount of variance in depression at followâup, after accounting for baseline depression. In addition, selfâcompassion moderated the effect of disgust propensity on depression at baseline, such that at high levels of selfâcompassion, disgust propensity no longer had a positive relationship with depression.
Conclusions
Disgust traits contribute to depression in people with skin conditions, while being selfâcompassionate may be protective against depression. High selfâcompassion also buffers the effects of disgust propensity on depression in people with skin conditions. The findings indicate the potential of compassionâfocused interventions for depression in people with skin conditions
Interoception and Respiratory Sinus Arrhythmia in Gambling Disorder
This is the author accepted manuscript. The final version is available from Wiley via the DOI in this recordGambling has long-standing links with excitement and physiological arousal, but prior research has not
considered i) gamblersâ ability to detect internal physiological signals, or ii) markers of parasympathetic
functioning. The present study measured interoception in individuals with gambling disorder, using selfreport measures and a heart beat counting task administered at rest. Resting state Respiratory Sinus
Arrhythmia (RSA), an index of heart rate variability, was measured as a proxy for parasympathetic
control and emotional regulation capacity. In a case-control design, 50 individuals with gambling
disorder were compared against 35 controls without gambling problems. Participants completed two
self-report measures of bodily awareness and a behavioural test of heart beat counting. A resting state
electrocardiogram (five minutes) was used to calculate RSA. There were no significant differences on
the self-report or behavioral interoception probes. The group with gambling disorder displayed
significantly reduced RSA, which at face value is consistent with reduced parasympathetic control.
However, the group difference in RSA did not survive controlling for age and smoking status, as
established predictors of heart rate variability. Our findings do not support any changes in interoceptive
processing in people with gambling disorder, at least under resting conditions. Our observation that
group differences in RSA are partly explained by smoking behavior highlights the importance of
controlling for nicotine use in future research characterizing physiological functioning and emotional
regulation in disordered gambling.Centre for Gambling Research at UBCProvince of British Columbia governmentBritish Columbia Lottery CorporationNatural Sciences and Engineering Research Council (Canada

Recovering from stillbirth: the effects of making and sharing memories on maternal mental health
Objective: This study examined whether the experience of creating and sharing memories of their babies is associated with mothersâ mental health after stillbirth, taking account of factors previously shown to be important. Background: Mothers of stillborn babies are usually offered the opportunity to spend time with and create memories of their babies. However, evidence on whether this leads to better mental health outcomes is equivocal. One possible explanation is that the impact of making memories is mediated by the extent to which women subsequently share these memories. Methods: Cross-sectional questionnaire study. Mothers (N = 162) of stillborn babies completed online questionnaires of how memories were made and shared, satisfaction with memory-making and sharing, professional and social support, and symptoms of depression, anxiety and PTSD. Results: The majority of mothers made and shared memories. The number of different memory-making activities was not associated with mental health outcomes. However, the degree to which mothers shared their memories was associated with fewer PTSD symptoms. Regression analyses showed that good mental health was most strongly associated with time since stillbirth, perceived professional support, sharing of memories and less wish to talk more about the baby. Conclusion: This study confirms research showing that time since stillbirth and perceived professional support is associated with better mental health following stillbirth and for the first time shows the importance of opportunities to share memories of the baby. Variation in sharing opportunities may contribute to inconsistencies in the association between making memories and mental health following stillbirth
Study protocol: evaluation of a parenting and stress management programme: a randomised controlled trial of Triple P discussion groups and stress control
<br>Background: Children displaying psychosocial problems are at an increased risk of negative developmental outcomes. Parenting practices are closely linked with child development and behaviour, and parenting programmes have been recommended in the treatment of child psychosocial problems. However, parental mental health also needs to be addressed when delivering parenting programmes as it is linked with parenting practices, child outcomes, and treatment outcomes of parenting programmes. This paper describes the protocol of a study examining the effects of a combined intervention of a parenting programme and a cognitive behavioural intervention for mental health problems.</br>
<br>Methods: The effects of a combined intervention of Triple P Discussion Groups and Stress Control will be examined using a randomised controlled trial design. Parents with a child aged 3?8?years will be recruited to take part in the study. After obtaining informed consent and pre-intervention measures, participants will be randomly assigned to either an intervention or a waitlist condition. The two primary outcomes for this study are change in dysfunctional/ineffective parenting practices and change in symptoms of depression, anxiety, and stress. Secondary outcomes are child behaviour problems, parenting experiences, parental self-efficacy, family relationships, and positive parental mental health. Demographic information, participant satisfaction with the intervention, and treatment fidelity data will also be collected. Data will be collected at pre-intervention, mid-intervention, post-intervention, and 3-month follow-up.</br>
<br>Discussion: The aim of this paper is to describe the study protocol of a randomised controlled trial evaluating the effects of a combined intervention of Triple P Discussion Groups and Stress Control in comparison to a waitlist condition. This study is important because it will provide evidence about the effects of this combined intervention for parents with 3?8?year old children. The results of the study could be used to inform policy about parenting support and support for parents with mental health problems.

Farming fit? Dispelling the Australian agrarian myth
Background: Rural Australians face a higher mental health and lifestyle disease burden (obesity, diabetes andcardiovascular disease) than their urban counterparts. Our ongoing research reveals that the Australian farmingcommunity has even poorer physical and mental health outcomes than rural averages. In particular, farm men andwomen have high rates of overweightness, obesity, abdominal adiposity, high blood pressure and psychologicaldistress when compared against Australian averages. Within our farming cohort we observed a significantassociation between psychological distress and obesity, abdominal adiposity and body fat percentage in thefarming population.Presentation of hypothesis: This paper presents a hypothesis based on preliminary data obtained from anongoing study that could potentially explain the complex correlation between obesity, psychological distress andphysical activity among a farming population. We posit that spasmodic physical activity, changing farm practicesand climate variability induce prolonged stress in farmers. This increases systemic cortisol that, in turn, promotesabdominal adiposity and weight gain.Testing the hypothesis: The hypothesis will be tested by anthropometric, biochemical and psychological analysismatched against systemic cortisol levels and the physical activity of the subjects.Implications of the hypothesis tested: Previous studies indicate that farming populations have elevated rates ofpsychological distress and high rates of suicide. Australian farmers have recently experienced challenging climaticconditions including prolonged drought, floods and cyclones. Through our interactions and through the media it isnot uncommon for farmers to describe the effect of this long-term stress with feelings of ‘defeat’. By gaining agreater understanding of the role cortisol and physical activity have on mental and physical health we maypositively impact the current rates of psychological distress in farmers.<br /
