Agency and the Annunciation

Prior research has revealed that when healthy participants, who are not artists, are asked to draw a person who is performing an action, they are more likely to position the agent on the left and the person or object receiving this action, the patient, on the right. Thus, the goal of this study was to learn whether in works of art, such as those portraying the Annunciation of the angel Gabriel to the Blessed Virgin Mary, artists would be more likely to place the angel, who is the agent, on the left of Mary, who is the patient. We found that in our sample of 604 paintings of the Annunciation by different artists that the agent Gabriel is significantly more frequently portrayed to left of Mary. Whereas this result supports the left-agent, right-patient hypothesis, the reason for this spatial bias is not entirely known, but may be related to several factors such as the learned left to right direction of reading/writing in European languages, left-versus right-sided emotional facial expressive asymmetries, a left-sided spatial attentional bias and a spatial motor-action preference of upper extremity for making abductive (left to right) movements when using the right upper extremity. Additionally, biblical explanations and theological principles may have influenced the organization of this scene.     

Mechanisms and the Evidence Hierarchy

Evidence-based medicine (EBM) makes use of explicit procedures for grading evidence for causal claims. Normally, these procedures categorise evidence of correlation produced by statistical trials as better evidence for a causal claim than evidence of mechanisms produced by other methods. We argue, in contrast, that evidence of mechanisms needs to be viewed as complementary to, rather than inferior to, evidence of correlation. In this paper we first set out the case for treating evidence of mechanisms alongside evidence of correlation in explicit protocols for evaluating evidence. Next we provide case studies which exemplify the ways in which evidence of mechanisms complements evidence of correlation in practice. Finally, we put forward some general considerations as to how the two sorts of evidence can be more closely integrated by EBM.     

Gambling primates: reactions to a modified Iowa Gambling Task in humans,chimpanzees and capuchin monkeys

Humans will, at times, act against their own economic self-interest, for example, in gambling situations. To explore the evolutionary roots of this behavior, we modified a traditional human gambling task, the Iowa Gambling Task (IGT), for use with chimpanzees, capuchin monkeys and humans. We expanded the traditional task to include two additional payoff structures to fully elucidate the ways in which these primate species respond to differing reward distributions versus overall quantities of rewards, a component often missing in the existing literature. We found that while all three species respond as typical humans do in the standard IGT payoff structure, species and individual differences emerge in our new payoff structures. Specifically, when variance avoidance and reward maximization conflicted, roughly equivalent numbers of apes maximized their rewards and avoided variance, indicating that the traditional payoff structure of the IGT is insufficient to disentangle these competing strategies. Capuchin monkeys showed little consistency in their choices. To determine whether this was a true species difference or an effect of task presentation, we replicated the experiment but increased the intertrial interval. In this case, several capuchin monkeys followed a reward maximization strategy, while chimpanzees retained the same strategy they had used previously. This suggests that individual differences in strategies for interacting with variance and reward maximization are present in apes, but not in capuchin monkeys. The primate gambling task presented here is a useful methodology for disentangling strategies of variance avoidance and reward maximization.     

Newborn Screening: Education,Consent, and the Residual Blood Spot. The Position of the National Society of Genetic Counselors

Newborn screening (NBS) is a minimally invasive lifesaving test. There is currently no federal mandate for NBS, thus states determine their own screening panel based on the recommendations of the Secretary’s Advisory Committee on Heritable Disorders in Newborn and Children (SACHDNC), which was recently re-chartered as the Discretionary Advisory Committee on Heritable Disorders in Newborns and Children (DACHDNC). After NBS is completed, a couple of residual blood spots remain. While some states allow these spots to be used for public health and scientific research purposes, parents are not always informed about these additional uses. This paper addresses the National Society of Genetic Counselors’ (NSGC’s) position about NBS and blood spot storage/use and the rationale for these positions. The National Society of Genetic Counselors strongly supports newborn screening for the uniform screening panel of conditions recommended by the Secretary’s Advisory Committee on Heritable Disorders in Newborns and Children. NSGC also supports storage and use of blood spot samples by newborn screening laboratories and transparent policies that govern these activities.     

Do Children Understand Iconic Gestures About Events as Early as Iconic Gestures About Entities?

Children can understand iconic co-speech gestures that characterize entities by age 3 (Stanfield et al. in J Child Lang 40(2):1–10, 2014; e.g., “I’m drinking” \(+\) tilting hand in C-shape to mouth as if holding a glass). In this study, we ask whether children understand co-speech gestures that characterize events as early as they do so for entities, and if so, whether their understanding is influenced by the patterns of gesture production in their native language. We examined this question by studying native English speaking 3- to 4 year-old children and adults as they completed an iconic co-speech gesture comprehension task involving motion events across two studies. Our results showed that children understood iconic co-speech gestures about events at age 4, marking comprehension of gestures about events one year later than gestures about entities. Our findings also showed that native gesture production patterns influenced children’s comprehension of gestures characterizing such events, with better comprehension for gestures that follow language-specific patterns compared to the ones that do not follow such patterns—particularly for manner of motion. Overall, these results highlight early emerging abilities in gesture comprehension about motion events.

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.
