Actual Reports and Perceptions of Body Image Concerns of Young Women and Their Friends

The present study was conducted to examine the role of friends in women’s body image concerns. Self and peer reports were completed by a convenience sample of 75 pairs of same gender female friends (N?=?150) from a small undergraduate university in Eastern Canada. In a conceptual replication of previous research, we first showed that self-reports of perceived pressure to be thin significantly predicted women’s own body image concerns when controlling for body mass. Of interest was the finding that body-related talk between friends that focused on exercise significantly predicted less body dissatisfaction. Additionally, by examining the relationships between self and peer reports, we showed that women’s perceptions of their friends’ body image concerns aligned to both self-reports and to friends’ actual reports suggesting that women likely projected their own self-views when perceiving friends. Moreover, using multiple regression analyses, we demonstrated that perceptions of friends, and not friends’ actual reports, predicted own body concerns. Besides the suggestions for future research stemming from limitations of the present study, we suggest that researchers interested in similarities between friends on women’s body image concerns include both perceptions of peers and actual peer reports.     

Spiritual Transformation: A Phenomenological Study Among Recovering Substance Abusers

As a complement to an earlier quantitative investigation, this qualitative study was concerned with describing the lived experience of spiritual transformation within the context of a 12-month resident substance abuse recovery program called the Lazarus Project, which is sponsored by a southern U.S. Pentecostal-based congregation. We conducted phenomenological interviews with 10 participants (eight European-Americans; two African-Americans) who had been in the program from six to nine?months and asked that they describe their most important spiritual experiences that brought about change. A hermeneutical analysis found that a pattern of five overlapping themes emerged consistently across all 10 protocols to describe the meaning of the experience of spiritual transformation for these participants. The themes were: (1) “Sick and Tired”, (2) Unmerited Love, (3) “I’m Changing,” (4) Fast/Gradual, and (5) Destiny. The themes are discussed from an existential perspective and related to the literature on spiritual transformation as well as the earlier quantitative study at the Lazarus Project.     

From Bayesian epistemology to inductive logic

Inductive logic admits a variety of semantics (Haenni et al. (2011) [7, Part 1]). This paper develops semantics based on the norms of Bayesian epistemology (Williamson, 2010 [16, Chapter 7]). Section 1 introduces the semantics and then, in Section 2, the paper explores methods for drawing inferences in the resulting logic and compares the methods of this paper with the methods of Barnett and Paris (2008) [2]. Section 3 then evaluates this Bayesian inductive logic in the light of four traditional critiques of inductive logic, arguing (i) that it is language independent in a key sense, (ii) that it admits connections with the Principle of Indifference but these connections do not lead to paradox, (iii) that it can capture the phenomenon of learning from experience, and (iv) that while the logic advocates scepticism with regard to some universal hypotheses, such scepticism is not problematic from the point of view of scientific theorising.     

Venturing into the visual voice: combining photos and interviews in phenomenological inquiry around marginalisation and chronic illness

In this article, we present a reflection on the research process of combining photographs with phenomenologically oriented interviews. Two studies in the field of chronic illness with marginalised individuals (lesbian, gay, bisexual and trans* people living with MS; men diagnosed with breast cancer) are employed to illustrate a range of conceptual, methodological and pragmatic issues. Both studies draw upon an integrative theoretical framework within a critical health psychology epistemological paradigm informed by phenomenological psychology and visual methodologies. The data collected for both studies have been analysed through interpretative phenomenological analysis (IPA). We offer some thoughts regarding certain challenges and opportunities of synergising verbal and visual data and illustrate our arguments through a series of examples from the two studies, which are critically discussed. We argue that qualitative research in psychology benefits from an enhanced multimethodological approach employing existential phenomenological psychology and visual methodologies, especially when exploring chronic illness in marginalised communities, and we outline benefits for the wider community of qualitative researchers in psychology.     

The relationship between pitch and space in congenital amusia

Congenital amusia manifests as a lifelong difficulty in making sense of musical sound. The extent to which this disorder is accompanied by deficits in visuo-spatial processing is an important question, bearing on the issue of whether pitch processing draws on supramodal spatial representations. The present study assessed different aspects of visuo-spatial processing with a range of tasks (Shepard-Metzler Mental Rotation, Corsi Blocks Task, Visual Patterns Test) in 14 amusics and matched controls. The absence of a group difference on any of these tasks fails to support a previous claim that the disorder is strongly related to deficits in spatial processing. However, a subgroup of amusics, with significantly elevated thresholds on a pitch direction discrimination task relative to the rest of the group, were slower, but equally accurate, at Mental Rotation. This finding is discussed in relation to the nature of supramodal representations of contour and strategies for dynamic mental transformation.     

Depression and quality of informal care: a longitudinal investigation of caregiving stressors

This research examined longitudinal associations between caregiving stressors, caregiver depression, and quality of care. Informal caregivers of elderly care recipients were interviewed at baseline (N = 310) and again one year later (N = 213). Hierarchical regression analyses indicated that increases in caregiving stressors (i.e., caregiver physical health symptoms, caregiver activity restriction, and care recipient controlling and manipulative behavior) were related to increased caregiver depression. In turn, increased caregiver depression and decreased caregiver respectful behavior predicted increases in potentially harmful behavior. These results extend previous cross-sectional findings and indicate that changes in caregiving stressors, caregiver depression, and caregiver respect over time may signal that intervention is warranted in order to forestall or prevent poor quality of care.     

Alcohol-Induced Amnesia and Personalized Drinking Feedback: Blackouts Predict Intervention Response

Alcohol-induced amnesia (“blackout”) is a reliable predictor of alcohol-related harm. Given its association with other negative consequences, experience of alcohol-induced amnesia may serve as a teachable moment, after which individuals are more likely to respond to intervention. To test this hypothesis, alcohol-induced amnesia was evaluated as a moderator of brief intervention effect on (a) alcohol-related consequences and (b) the proposed intervention mediators, protective behavioral strategies and peak blood alcohol concentration (BAC). Baseline alcohol risk measured using the Alcohol Use Disorders Identification Test (AUDIT) was also evaluated as a moderator to rule out the possibility that amnesia is simply an indicator of more general alcohol risk. College students (N = 198) reporting alcohol use in a typical week completed assessments at baseline and 1-month follow-up as part of a larger intervention trial. Participants were randomized to assessment only (AO; n = 58) or personalized feedback intervention (PFI; n = 140). Hierarchical regression was used to examine direct and indirect intervention effects. A significant group-by-amnesia interaction revealed that only PFI participants who had experienced alcohol-induced amnesia in the past month reported decreases in alcohol consequences at 1-month follow-up. The PFI reduced alcohol-related consequences indirectly through changes in peak BAC, but only among those who had experienced amnesia at baseline. In contrast, baseline alcohol risk (AUDIT) did not moderate intervention effects, and use of protective behavioral strategies did not statistically mediate intervention effects. Findings suggest that loss of memory for drinking events is a unique determinant of young adult response to brief alcohol intervention. Normative feedback interventions may be particularly effective for individuals who have experienced alcohol-induced amnesia in the past 30 days.     

Sensory-specific satiety is intact in amnesics who eat multiple meals

What is the relationship between memory and appetite? We explored this question by examining preferences for recently consumed food in patients with amnesia. Although the patients were unable to remember having eaten, and were inclined to eat multiple meals, we found that sensory-specific satiety was intact in these patients. The data suggest that sensory-specific satiety can occur in the absence of explicit memory for having eaten and that impaired sensory-specific satiety does not underlie the phenomenon of multiple-meal eating in amnesia. Overeating in amnesia may be due to disruption of learned control by physiological aftereffects of a recent meal or to problems utilizing internal cues relating to nutritional state.     

Objective Bayesianism with predicate languages

Objective Bayesian probability is often defined over rather simple domains, e.g., finite event spaces or propositional languages. This paper investigates the extension of objective Bayesianism to first-order logical languages. It is argued that the objective Bayesian should choose a probability function, from all those that satisfy constraints imposed by background knowledge, that is closest to a particular frequency-induced probability function which generalises the λ = 0 function of Carnap’s continuum of inductive methods.
