An electrophysiological comparison of visual categorization and recognition memory

Object categorization emphasizes the similarities that bind exemplars into categories, whereas recognition memory emphasizes the specific identification of previously encountered exemplars. Mathematical modeling has highlighted similarities in the computational requirements of these tasks, but neuropsychological research has suggested that categorization and recognition may depend on separate brain systems. Following training with families of novel visual shapes (blobs), event-related brain potentials (ERPs) were recorded during both categorization and recognition tasks. ERPs related to early visual processing (N1, 156–200 msec) were sensitive to category membership. Middle latency ERPs (FN400 effects, 300–500 msec) were sensitive to both category membership and old/new differences. Later ERPs (parietal effects, 400–800 msec) were primarily affected by old/new differences. Thus, there was a temporal transition so that earlier processes were more sensitive to categorical discrimination and later processes were more sensitive to recognition-related discrimination. Aspects of these results are consistent with both mathematical modeling and neuropsychological perspectives.     

Racism in the Hands of an Angry God: How Image of God Impacts Cultural Racism in Relation to Police Treatment of African Americans

Previous research suggests an angry God image is a narrative schema predicting support for more punitive forms of criminal justice. However, this research has not explored the possibility that racialization may impact one's God image. We perform logistic regression on Wave V of the Baylor Religion Survey to examine the correlation between an angry God image and the belief that police shoot Blacks more often because Blacks are more violent than Whites (a context-specific form of cultural racism). Engaging critical insights from intersectionality theory, we also interact angry God image with both racialized identity and racialized religious tradition. Results suggest that the angry God schema is associated with this form of cultural racism for White people generally as well as White Evangelicals, yet for Black Protestants, belief in an angry God is associated with resistance against this type of cultural racism.     

The Basic Courses for the Study of Religions at the University of Southern Denmark

This essay is part of a collection of short essays solicited from authors around the globe who teach religion courses at the college level (not for professional religious training). They are published together with an introduction in Teaching Theology and Religion 18:3 (July 2015). The authors were asked to provide a brief overview of the curriculum, student learning goals, and pedagogical techniques employed in their courses.     

Broad Consent for Research With Biological Samples: Workshop Conclusions

Different types of consent are used to obtain human biospecimens for future research. This variation has resulted in confusion regarding what research is permitted, inadvertent constraints on future research, and research proceeding without consent. The National Institutes of Health (NIH) Clinical Center's Department of Bioethics held a workshop to consider the ethical acceptability of addressing these concerns by using broad consent for future research on stored biospecimens. Multiple bioethics scholars, who have written on these issues, discussed the reasons for consent, the range of consent strategies, and gaps in our understanding, and concluded with a proposal for broad initial consent coupled with oversight and, when feasible, ongoing provision of information to donors. This article describes areas of agreement and areas that need more research and dialogue. Given recent proposed changes to the Common Rule, and new guidance regarding storing and sharing data and samples, this is an important and timely topic.     

P300 amplitude variations,prior probabilities,and likelihoods: A Bayesian ERP study

The capability of the human brain for Bayesian inference was assessed by manipulating probabilistic contingencies in an urn-ball task. Event-related potentials (ERPs) were recorded in response to stimuli that differed in their relative frequency of occurrence (.18 to .82). A veraged ERPs with sufficient signal-to-noise ratio (relative frequency of occurrence > .5) were used for further analysis. Research hypotheses about relationships between probabilistic contingencies and ERP amplitude variations were formalized as (in-)equality constrained hypotheses. Conducting Bayesian model comparisons, we found that manipulations of prior probabilities and likelihoods were associated with separately modifiable and distinct ERP responses. P3a amplitudes were sensitive to the degree of prior certainty such that higher prior probabilities were related to larger frontally distributed P3a waves. P3b amplitudes were sensitive to the degree of likelihood certainty such that lower likelihoods were associated with larger parietally distributed P3b waves. These ERP data suggest that these antecedents of Bayesian inference (prior probabilities and likelihoods) are coded by the human brain.     

Individual,Housing, and Neighborhood Predictors of Psychological Integration Among Vulnerably Housed and Homeless Individuals

The current longitudinal study evaluated the individual, housing, and neighborhood characteristics predictive of feeling psychologically integrated within one's neighborhood among a population of homeless and vulnerably housed individuals. Participants were recruited at homeless shelters, meal programs, and rooming houses in Ottawa, Canada and participated in three in‐person interviews, each approximately 1 year apart. Prospective and cross‐sectional predictors of psychological integration at Follow‐up 1 and Follow‐up 2 were examined. There were 397 participants at baseline, 341 at Follow‐up 1 and 320 at Follow‐up 2. A hierarchical multiple regression uncovered several significant predictors of psychological integration. The most salient and common predictors were being older, having greater social support, living in high quality housing, and residing in a neighborhood with a positive impact. Implications for service provision and policy advancements are discussed.     

Ideas of justice and reconstructions of Confucian justice

Confucianism tends to play only a marginal role in current theorizing about justice, which is a global pursuit dominated by Western theory and its strong tendency to assume that justice refers to some substantive conception of distributive, socioeconomic justice. This article examines and compares reconstructions of Confucian justice by Joseph Chan, May Sim, and Fan Ruiping. Each reconstruction makes reference to both classical and modern Western justice theory and thus each involves a comparative approach; indeed, each reconstruction seeks ultimately, in its own distinctive fashion, to present a version of Confucian justice that is comparable with modern Western justice theory. In this article we assess, critically and comparatively, the tertium comparationis and the arguments in each reconstruction. While our analysis does not wholly endorse any of the reconstructions, it shows that there is a richness and vitality to Confucian justice theory that merits proper consideration in justice theory conceived as a truly global and cosmopolitan discipline.     

Challenges and Opportunities of Lifelog Technologies: A Literature Review and Critical Analysis

In a lifelog, data from various sources are combined to form a record from which one can retrieve information about oneself and the environment in which one is situated. It could be considered similar to an automated biography. Lifelog technology is still at an early stage of development. However, the history of lifelogs so far shows a clear academic, corporate and governmental interest. Therefore, a thorough inquiry into the ethical aspects of lifelogs could prove beneficial to the responsible development of this field. This article maps the main ethically relevant challenges and opportunities associated with the further development of lifelog technologies as discussed in the scholarly literature. By identifying challenges and opportunities in the current debate, we were able to identify other challenges and opportunities left unmentioned. Some of these challenges are partly explained by a blind spot in the current debate. Whilst the current debate focuses mainly on lifelogs held by individuals, lifelogs held by governmental institutions and corporations pose idiosyncratic ethical concerns as well. We have provided a brief taxonomy of lifelog technology to show the variety in uses for lifelogs. In addition, we provided a general approach to alleviate the ethical challenges identified in the critical analysis.
