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.     

Statistical decision theory and evolution

Two recent articles by Geisler and Diehl use Bayesian statistical decision theory to model the co-evolution of predator and prey in a simple, game-like environment. The prey is characterized by its coloration. The predator is characterized by the chromatic sensitivity of its visual system and its willingness to attack. The authors demonstrate how the coloration of prey and the perceptual system of the predator co-evolve, converging to a Nash equilibrium for both species.     

Intention,Emotion, and Action: A Neural Theory Based on Semantic Pointers

We propose a unified theory of intentions as neural processes that integrate representations of states of affairs, actions, and emotional evaluation. We show how this theory provides answers to philosophical questions about the concept of intention, psychological questions about human behavior, computational questions about the relations between belief and action, and neuroscientific questions about how the brain produces actions. Our theory of intention ties together biologically plausible mechanisms for belief, planning, and motor control. The computational feasibility of these mechanisms is shown by a model that simulates psychologically important cases of intention.

Genetic Counselors’ Experience with and Opinions on the Management of Newborn Screening Incidental Carrier Findings

Newborn screening (NBS) is a public health program whose aim is to identify infants who will be clinically affected with a serious metabolic, genetic, or endocrine disorder; however, the technology utilized by many NBS programs also detects infants who are heterozygous carriers for autosomal recessive conditions. Discussion surrounding disclosure of these incidental carrier findings remains controversial. The purpose of this study was to assess genetic counselors’ attitudes about disclosure of carrier status results generated by NBS and to gather data on their experiences with incidental carrier findings. An electronic survey was distributed to genetic counselors of all specialties via the NSGC listserv, and a total of 235 survey responses were analyzed. Quantitative data were analyzed using IBM SPSS v24, and qualitative data were manually analyzed for thematic analysis. Results show that the counselor participants were overall in favor of routine disclosure. Those with experience in NBS were much more likely to strongly agree with one or more reasons for disclosure (p?<?0.001), whereas those with five or fewer years of experience were more likely to strongly agree with one or more reasons for non-disclosure (p?=?0.031). Qualitative analysis identified key motivating factors for disclosure, including helping parents to understand a positive screen, parents may otherwise be unaware of reproductive risk and they may not otherwise have access to this information, and, while genetic testing is inherently a complex and ambiguous process, this does not justify non-disclosure. The main motivating factor for non-disclosure was the need for better counseling and informed consent. The data suggest that implementation of an “opt-in/out” policy for parents to decide whether or not to receive incidental findings would be beneficial. The results of this study support the continued disclosure of incidental carrier findings; however, additional research is necessary to further determine and implement the most effective disclosure practices.
