The Limits of Learning: Habermas' Social Theory and Religion

Habermas' view that contemporary philosophy and social theory can learn from religious traditions calls for closer consideration. He is correct to hold that religious traditions constitute a reservoir of potentially important meanings that can be critically appropriated without emptying them of their motivating and inspirational power. However, contrary to what he implies, his theory allows for learning from religion only to a very limited degree. This is due to two core elements of his conceptual framework, both of which are key features of his account of postmetaphysical thinking. The first is the requirement of ethical agnosticism; this requires philosophy and social theory to refrain from offering guidance on questions of the good life. The second is his language‐immanent conception of truth in the domain of practical reason; this follows from his rejection of any source of validity beyond human communication in this domain. I make the case for a more robust account of learning from religious traditions and metaphysical worldviews, arguing that for this purpose Habermas must modify his requirement of ethical agnosticism and relinquish his language‐immanent conception of truth.     

The Obligation to Know: Information and the Burdens of Citizenship

Contemporary persons are daily confronted with enormous quantities of information, some of which reveal causal connections between their actions and harm that is visited upon distant others. Given their limited cognitive and information processing capacities, persons cannot reasonably be expected to respond to every cry for help or call to action, but neither can they defensibly refuse to hear and reflect upon any of them. Persons have a limited obligation to know, I argue, which requires that they inform themselves and others about their role in harmful social practices, with a view toward challenging the norms that sustain such practices. In this paper, I explore this obligation to know, and the related idea of excusable ignorance, offering accounts of the epistemic burden that it entails for persons in their capacities as citizens and in the context of global climate change and of reproach as a potentially effective tool for rectifying rather than excusing ignorance.     

The effect of biased lineup instructions on eyewitness identification confidence

Although it is well‐known that biased lineup instructions (i.e., those that do not inform witnesses the perpetrator may not be in the lineup) inflate false identifications, their effects on witness confidence are less well understood due to methodological limitations of past studies. We report two studies that use novel methodologies to obviate these limitations. Study 1 (N = 177) demonstrated that biased lineup instructions increased witnesses' average estimates of the likelihood that a lineup member is guilty. Study 2 (N = 137) introduces a novel debiasing paradigm that allows a parsing of choosers into those who made an identification only because of the biased instructions (induced choosers), and those who would have chosen despite the instructions (inherent choosers). Biased lineup instructions inflated confidence only among induced choosers, but not among inherent choosers. Contrary to legal reasoning, witness confidence is an insufficient metric to determine the suggestiveness of biased instructions.     

Transcranial Direct Current Stimulation (tDCS) over the Intraparietal Sulcus Does Not Influence Working Memory Performance

Mixed results of the impact of transcranial direct current stimulation (tDCS) on working memory have been reported. Contrarily to previous studies who focused mainly on stimulating the dorsolateral prefrontal cortex, we modulated the left intraparietal sulcus (IPS) area which is considered to support attentional control aspects of working memory. Using a within-participant experimental design, participants completed three different conditions: anodal stimulation of the IPS, cathodal stimulation of the IPS, and sham stimulation of the IPS. Both visual and verbal working memory tasks were administered. In the visual task, participants had to memorize a random set of colored figures. In the verbal task, participants had to memorize a string of letters. Working memory load was manipulated in both tasks (six figures/letters vs. two figures/letters). No significant differences in accuracy or reaction time between the anodal, cathodal and sham conditions were found. Bayesian analysis supported evidence for an absence of effect. The results of the present study add to the growing body of contradictory evidence regarding the modulatory effects of single session tDCS on working memory performance.     

Childhood Irritability: Predictive Validity and Mediators of Adolescent Psychopathology

Despite its transdiagnostic significance, there is modest evidence with respect to the predictive validity of childhood irritability, especially across developmental periods; similarly, little is known about explanatory factors underlying these predictions. This study had two goals: (1) to test the predictive validity of childhood irritability with respect to adolescent internalizing and externalizing problems, controlling for baseline ADHD and related psychopathology and (2) to test theoretically-derived family (i.e., parenting behavior, parenting stress) and social (i.e., peer status, social skills) constructs as explanatory factors of adolescent psychopathology. Two hundred thirty ethnically diverse (51.5% White) 5–10-year-old youth (32% female) with (n?=?121) and without (n?=?110) ADHD completed three separate laboratory-based assessments across six to seven years. Temporally-ordered predictors, putative mediators, and psychopathology outcomes were assessed using multiple informants (i.e., parent, teacher, youth) and methods (i.e., structured interviews, normed rating scales). Controlling for demographic factors, clinical correlates, and baseline psychopathology, childhood irritability uniquely predicted adolescent externalizing problems, but not internalizing problems. Next, analyses revealed that low social skills partially explained predictions of adolescent internalizing problems. However, family or social factors did not underlie predictions of adolescent externalizing problems. These preliminary findings support the predictive validity of childhood irritability with respect to early adolescent externalizing problems and implicate low social skills as a potentially unique mediator of internalizing outcomes. Intervention-induced improvements in social skills may minimize emergent psychopathology initiated by significant childhood irritability.

     

Personality disorder and violence: understand violence risk: an introduction to the special section personality disorder and violence

This paper introduces the Special Section on personality disorder and violence. The first paper evaluates the impact of removing the Psychopathy Checklist (PCL-R) as a mandatory element of a major approach to the assessment of violence risk-the HCR-20. The second paper considers violence to self as well as violence to others; it examines the influence of dysfunctional personality traits in a sample of female offenders. The third paper provides a systematic framework for risk formulation, discussing how to bridge the gap between nomothetic research and the individual case. This paper concludes by arguing that there is a need to shift perspective from asking "what?" dysfunctional traits are relevant to future violence to "why?" are particular traits relevant. The "why?" question is particularly germane in the forensic arena where expert testimony must endeavor to provide a causal explanation of risk processes at the level of the individual.     

Psychopathy in Iran: a cross-cultural study

Few cross-cultural studies have assessed psychopathy and none have included a sample from non-western countries. This study investigated the factor structure of the Psychopathy Checklist: Screening Version (PCL:SV) in an Iranian sample, and compared the results with a western sample. Three hundred fifty-one Iranian prisoners were compared with 405 participants of the standardization sample of the PCL:SV. Confirmatory factor analysis and item response theory method were used for data analysis. The Iranian data fitted well with the hierarchical three-factor model of psychopathy and neither two- nor four-factor models showed an adequate fit. Differential item functioning existed across samples, with discriminatory power of factor 1 (arrogant and deceitful interpersonal style) being lower in the Iranian sample that for factor 2 (deficient emotional experience) being greater in the Iranian sample than the standardization sample. Deficient emotional experience might be the most significant factor in diagnosing psychopathy, regardless of the studied culture. Other factors appear to be relatively culture-specific.
