Characterizing belief bias in syllogistic reasoning: A hierarchical Bayesian meta-analysis of ROC data

The belief-bias effect is one of the most-studied biases in reasoning. A recent study of the phenomenon using the signal detection theory (SDT) model called into question all theoretical accounts of belief bias by demonstrating that belief-based differences in the ability to discriminate between valid and invalid syllogisms may be an artifact stemming from the use of inappropriate linear measurement models such as analysis of variance (Dube et al., Psychological Review, 117(3), 831–863, 2010). The discrepancy between Dube et al.’s, Psychological Review, 117(3), 831–863 (2010) results and the previous three decades of work, together with former’s methodological criticisms suggests the need to revisit earlier results, this time collecting confidence-rating responses. Using a hierarchical Bayesian meta-analysis, we reanalyzed a corpus of 22 confidence-rating studies (N =?993). The results indicated that extensive replications using confidence-rating data are unnecessary as the observed receiver operating characteristic functions are not systematically asymmetric. These results were subsequently corroborated by a novel experimental design based on SDT’s generalized area theorem. Although the meta-analysis confirms that believability does not influence discriminability unconditionally, it also confirmed previous results that factors such as individual differences mediate the effect. The main point is that data from previous and future studies can be safely analyzed using appropriate hierarchical methods that do not require confidence ratings. More generally, our results set a new standard for analyzing data and evaluating theories in reasoning. Important methodological and theoretical considerations for future work on belief bias and related domains are discussed.     

On Biotechnology,Theology, and the Human Sciences

There may be very good Christian theological reasons to oppose human biotechnological enhancement. It is, however, difficult to discern what they are. Much of the specifically Christian response to transhumanist biotechnological enhancement has revolved around the metaphysics of human persons; this is hardly surprising, given that similar themes appear in other bioethical themes, such as over in vitro fertilization, abortion, and euthanasia. The main aim of this paper is to clarify the theological requirements for such responses, particularly those that are mistakenly delegated to scientists. In particular, the paper will focus on the need for a Christian theological account of human nature that does not unduly rely on biological accounts of the same.     

Experiences of Adults Who Identify as Primary Caregivers

The role of primary caregiver is unique. Understanding the role of the primary caregiver will better inform those in the counseling profession. The purpose of this qualitative research study was to gain a clearer perspective of the lived experiences of adults who identify as primary caregivers. The authors conducted semistructured interviews with 6 Caucasian female participants and analyzed the data using interpretative phenomenological analysis. The findings include personal perceptions and caregiver experiences pertaining to the caregiver role, caregiver mentality, professional identity, social and emotional responses, and self‐care among caregivers throughout the caregiving process. Implications for counselors and future research are presented.     

Looking for Renaissance People: Examining Domain Specificity-Generality of Creativity Using Item Response Theory Models

Creativity is increasingly identified as a key educational outcome at the local, regional, and national levels in several countries. Yet one key issue about the nature of creativity remains controversial: Whether creativity is domain specific or domain general. Resolving this issue would significantly impact the way creativity is identified, nurtured, and assessed in our schools. Three-hundred and fifty-nine undergraduate and graduate students completed measures that assessed their creative achievements in 6 distinct domains. Results based on item response theory models suggested that creativity was domain general, rather than domain specific, and part of the evidence provided by the classical test theory models seemed to favor the domain-specific view. These findings have great implications for researchers and practitioners who aim to assess and promote creativity in schools.     

From Neither/Nor to Both/And: Reconfiguring the Life and Legacy of Shirdi Sai Baba in Hagiography

The paper focuses on two hagiographic texts about the Indian saint Shirdi Sai Baba: G. R. Dabholkar’s ?rī Sāī Satcarita (1930) in Marathi and B. V. Narasimhaswami’s four-volume Life of Sai Baba (1955–69) in English. A comparative study of these texts highlights a notable shift in the saint’s life story. Whereas Dabholkar describes a saint who is “neither Hindu nor Muslim,” Narasimhaswami emphasizes particular devotional testimonies to reconstruct Shirdi Sai Baba as a syncretistic figure who is “both Hindu and Muslim.” Narasimhaswami’s reconstruction also reveals a politics of compositeness, in which a dominant Hindu embrace contains a domesticated Muslim-ness.     

Force versus fury: Sex differences in the relationships among physical and psychological threat potential,the facial width‐to‐height ratio,and judgements of aggressiveness

Individuals with larger facial width‐to‐height ratios (FWHRs) are judged as more threatening, and engage in more threat‐related behavior, than do individuals with smaller FWHRs. Here we identified components of threat potential that are related to the FWHR. In Study 1, the FWHR was correlated positively with physical threat potential (bicep size) in women and with both physical and psychological (anger proneness) threat potential in men. Behavioral aggression was measured in a subset of these participants using the Point Subtraction Aggression Paradigm (costly aggression) and a Money Allocation Task (non‐costly aggression). Psychological (but not physical) threat potential predicted non‐costly aggression and physical (but not psychological) threat potential predicted costly aggression. In Study 2, a separate set of participants judged the anger proneness, strength, or aggressiveness of male participants photographed in Study 1. Participants’ judgements of all three characteristics were associated with the FWHR, and there were sex differences in how aggressiveness was conceptualized (for women, aggressiveness was associated with anger proneness, for men, aggressiveness was associated with strength). These results are consistent with the hypothesis that the FWHR may be an adaptation to cue the threat potential of men.

     

New Directions in the Cognitive-Behavioral Treatment of OCD: Theory,Research, and Practice

The beneficial effects of cognitive-behavioral interventions (particularly exposure and response prevention) for OCD are among the most consistent research findings in the mental health literature. Nevertheless, even after an adequate trial, many individuals experience residual symptoms, and others never receive adequate treatment due to limited access. These and other issues have prompted clinicians and researchers to search for ways to improve the conceptual and practical aspects of existing treatment approaches, as well as look for augmentation strategies. In the present article, we review a number of recent developments and new directions in the psychological treatment of OCD, including (a) the application of inhibitory learning approaches to exposure therapy, (b) the development of acceptance-based approaches, (c) involvement of caregivers (partners and parents) in treatment, (d) pharmacological cognitive enhancement of exposure therapy, and (e) the use of technology to disseminate effective treatment. We focus on both the conceptual/scientific and practical aspects of these topics so that clinicians and researchers alike can assess their relative merits and disadvantages.
