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

Educating through Exemplars: Alternative Paths to Virtue

This paper confronts Zagzebski’s 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 Blum’s definitions of ‘moral hero’ and ‘moral saint’ (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

Parenting and child behaviour as predictors of toothbrushing difficulties in young children

Background: Oral disease is one of the most prevalent chronic health conditions affecting children. Twice-daily toothbrushing is recommended to promote good oral health; however, a large proportion of Australian families are not meeting this recommendation. Aim: This study aimed to identify important barriers to regular toothbrushing for young children. Design: In this study, 239 parents of 0- to 4-year-old children completed an online survey that investigated child, family, and parent factors associated with child toothbrushing. Hierarchical linear regression was used to identify predictors of toothbrushing frequency in children and perceived difficulty of the task by parents. Results: We found that parent factors, specifically oral health knowledge, were the most significant predictors of toothbrushing frequency. Conversely, parent factors did not contribute significantly to the prediction of perceived difficulty of toothbrushing once family and child factors were taken into account. Oral health knowledge and use of routines were identified as the most important predictors of toothbrushing frequency, whereas resistant child behaviour and household organisation were found to be the most important predictors of perceived difficulty of regular toothbrushing. Conclusions: The findings of the study have implications for behavioural interventions to support parents, as well as directions for future research

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) gamblers’ 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 mothers’ 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

Cognitive biases to healthy and unhealthy food words predict change in BMI

The current study explored the predictive value of cognitive biases to food cues (assessed by emotional Stroop and dot probe tasks) on weight change over a 1-year period. This was a longitudinal study with undergraduate students (N = 102) living in shared student accommodation. After controlling for the effects of variables associated with weight (e.g., physical activity, stress, restrained eating, external eating, and emotional eating), no effects of cognitive bias were found with the dot probe. However, for the emotional Stroop, cognitive bias to unhealthy foods predicted an increase in BMI whereas cognitive bias to healthy foods was associated with a decrease in BMI. Results parallel findings in substance abuse research; cognitive biases appear to predict behavior change. Accordingly, future research should consider strategies for attentional retraining, encouraging individuals to reorient attention away from unhealthy eating cues

Atypical bodily self-awareness in vicarious pain responders

Vicarious perception refers to the ability to co-represent the experiences of others. Prior research has shown considerable inter-individual variability in vicarious perception of pain, with some experiencing conscious sensations of pain on their own body when viewing another person in pain (conscious vicarious perception / mirror-pain synaesthesia). Self-Other Theory proposes that this conscious vicarious perception may result from impairments in self-other distinction and maintaining a coherent sense of bodily self. In support of this, individuals who experience conscious vicarious perception are more susceptible to illusions of body ownership and agency. However, little work has assessed whether trait differences in bodily self-awareness are associated with conscious vicarious pain. Here we addressed this gap by examining individual difference factors related to awareness of the body, in conscious vicarious pain responders. Increased self-reported depersonalisation and interoceptive sensibility was found for conscious vicarious pain responders compared with non-responders, in addition to more internally-oriented thinking (associated with lower alexithymia). There were no significant differences in trait anxiety. Results indicate that maintaining a stable sense of the bodily self may be important for vicarious perception of pain, and that vicarious perception might also be enhanced by attention towards internal bodily states

Traumatic life experiences and religiosity in eight countries

We present two datasets from a project about the relationship between traumatic life experiences and religiosity. These include data from 1,754 individuals in the United States (n = 322), Brazil (n = 205), China (n = 202), India (n = 205), Indonesia (n = 205), Russia (n = 205), Thailand (n = 205), and Turkey (n = 205). Surveys were consistent across samples: they include measures of traumatic life experiences, negative affective traits, existential security, life satisfaction, death anxiety, and various religious beliefs, attitudes, and behaviours. Psychometric evaluations of measures of supernatural belief and death anxiety were conducted
