Religious obsessions and compulsions in a non-clinical sample: the Penn Inventory of Scrupulosity (PIOS)

The present investigation reports on the development and psychometric evaluation of the Penn Inventory of Scrupulosity (PIOS), a 19-item self-report scale measuring religious obsessive-compulsive symptoms. Factor analysis yielded a two factor solution with the first subscale measuring fears about having committed sin, and the second measuring fears concerning punishment from God. Using a sample of college students, the PIOS was shown to be internally consistent and possess good convergent and discriminant validity. Highly devout participants evidenced higher scores on both PIOS subscales, but devout Jews evidenced fewer fears of sin and punishment from God compared to devout Protestants or Catholics. The PIOS has utility both as a research and clinical tool.     

Epinephrine enhancement of human memory consolidation: interaction with arousal at encoding

Abundant evidence indicates that endogenous stress hormones like epinephrine and cortisol modulate memory consolidation in animals. Despite this evidence, there has been no demonstration that endogenous stress hormones modulate memory consolidation in humans. In the present study, healthy subjects viewed a series of 21 slides, and immediately after received an intravenous infusion of either saline or epinephrine (40 or 80 ng/kg/min). Memory for the first three (primacy) and last three (recency) slides viewed was assessed with an incidental free recall test one week later. Epinephrine dose-dependently increased memory for the primacy slides, but did not affect memory of the recency slides. A subsequent experiment involving new subjects revealed significantly higher electrodermal responses to the primacy compared with recency slides. These findings support the view (Gold & McGaugh, 1975) that endogenous stress hormones modulate memory consolidation for experiences that induce their release. Additionally, they suggest that in humans these hormones may interact with the degree of arousal at initial encoding of information to modulate memory consolidation processes for that information.     

Sex-related difference in amygdala activity during emotionally influenced memory storage

We tested the possibility suggested by previous imaging studies that amygdala participation in the storage of emotionally influenced memory is differentially lateralized in men and women. Male and female subjects received two PET scans for regional cerebral glucose-one while viewing a series of emotionally provocative (negative) films, and a second while viewing a series of matched, but emotionally more neutral, films. Consistent with suggestions from several previously published studies, enhanced activity of the right, but not the left, amygdala in men was related to enhanced memory for the emotional films. Conversely, enhanced activity of the left, but not the right, amygdala in women was related to enhanced memory for the emotional films. These results demonstrate a clear gender-related lateralization of amygdala involvement in emotionally influenced memory, and indicate that theories of the neurobiology of emotionally influenced memory must begin to account for the influence of gender.     

A model of the neural mechanisms underlying multisensory integration in the superior colliculus

Much of the information about multisensory integration is derived from studies of the cat superior colliculus (SC), a midbrain structure involved in orientation behaviors. This integration is apparent in the enhanced responses of SC neurons to cross-modal stimuli, responses that exceed those to any of the modality-specific component stimuli. The simplest model of multisensory integration is one in which the SC neuron simply sums its various sensory inputs. However, a number of empirical findings reveal the inadequacy of such a model; for example, the finding that deactivation of cortico-collicular inputs eliminates the enhanced response to a cross-modal stimulus without eliminating responses to the modality-specific component stimuli. These and other empirical findings inform a computational model that accounts for all of the most fundamental aspects of SC multisensory integration. The model is presented in two forms: an algebraic form that conveys the essential insights, and a compartmental form that represents the neuronal computations in a more biologically realistic way.     

Psychopathy in adolescence and criminal recidivism in young adulthood: longitudinal results from a multiethnic sample of youthful offenders

Very few studies to date have examined the long-term predictive validity of psychopathy among juveniles. The current study reports general and violent recidivism data for an ethnically heterogeneous sample of male offenders (n = 75) who had been administered the Psychopathy Checklist: Youth Version (PCL: YV) in 1996 when they were on average 16 years of age. Neither total scores nor factor scores of the PCL: YV predicted general or violent reconvictions throughout this time frame. These modest effects underscore recent concerns raised about the utility of psychopathy as a risk factor for future criminality, particularly among multiethnic offender samples.     

Separation, Sickness, and Depression: A New Perspective on an Old Animal Model

ABSTRACT— Studies of prolonged separation from the attachment figure that were conducted with infant monkeys during the middle of the 20th century identified a passive behavioral response, termed "despair," that appeared to model human depressive illness. Studies in guinea pigs, which exhibit filial attachment that resembles attachment in monkeys, have described a similar passive response to briefer periods of maternal separation. Recent evidence indicates that elements of the immune system mediate the passive behavioral response of guinea pigs. These findings accord well with current ideas that immune responses contribute to depressive illness, suggest new hypotheses about how maternal separation might promote depression, and give us a rodent model in which such hypotheses might be tested.     

Serving God and Country? Religious Involvement and Military Service Among Young Adult Men

Despite important connections between religion and military action throughout world history, scholars have seldom explored the association between religiosity and military enlistment. Using data from the National Longitudinal Study of Adolescent Health (Add Health), we used a person‐oriented analysis to categorize young men according to patterns of adolescent religious involvement. Youth indentified as “highly religious evangelical” are more likely to enlist in the military compared to their “highly religious nonevangelical” and “nonreligious” counterparts; however, these findings hold only for those young men without college experience. These findings are discussed along with study limitations and promising directions for future research.     

On the Limits of Rights and Representation

This essay explores the degree to which public reason can sustain political liberalism's commitment to justice and pluralism without attending to the role of what Jeffrey Stout calls “cultural inheritance” in shaping and justifying political commitments. At issue is whether public reason is the best resource for guiding conversations on political matters that are enmeshed in religious commitments and moral beliefs. Unless public reason can account for cultural inheritance, and foster a deliberative context in which political actors might grapple with the relationship between overlapping political claims and comprehensive doctrines, public reason will remain narrow and inadequate in a contemporary world where epistemic diversity is increasingly at odds with political liberalism's normative model of social cooperation and public deliberation.
