The role of explicit memory processes in cross-modal priming: an investigation of stem completion priming in amnesia

To clarify the role of explicit memory processes in cross-modal priming, two experiments examined the status of cross-modal stem completion priming in amnesia. Experiment 1 used a standard behavioral paradigm in which stems corresponding to studied and unstudied words were intermixed. Amnesic patients showed intact within- and cross-modal priming, but, in contrast to controls, they recognized very few of their completions as having been on the study list. This finding suggests that memorial awareness is not necessary for cross-modal priming to occur. Experiment 2 used a paradigm modeled after functional imaging studies, in which stems corresponding to studied and unstudied words were blocked. Amnesic patients showed intact within-modal priming, but impaired cross-modal priming. This finding is consistent with the notion that a blocked format induces voluntary retrieval strategies in normal participants.     

The Role of Emotion Regulation and Children's Early Academic Success

This study investigated the role of emotion regulation in children's early academic success using a sample of 325 kindergarteners. A mediational analysis addressed the potential mechanisms through which emotion regulation relates to children's early academic success. Results indicated that emotion regulation was positively associated with teacher reports of children's academic success and productivity in the classroom and standardized early literacy and math achievement scores. Contrary to predictions, child behavior problems and the quality of the student teacher relationship did not mediate these relations. However, emotion regulation and the quality of the student-teacher relationship uniquely predicted academic outcomes even after accounting for IQ. Findings are discussed in terms of how emotion regulation skills facilitate children's development of a positive student-teacher relationship as well as cognitive processing and independent learning behavior, all of which are important for academic motivation and success.     

Contribution of imitative suicide to the suicide rate in prisons

Suicide rates in prisons are high. Our aim was to investigate the contribution of imitative suicide to the prison suicide rate. We used Knox tests for space-time clustering in a case register of natural and self-inflicted deaths in prisons in England and Wales and model simulations to estimate the effect size. We found significant space-time clustering among 657 self-inflicted deaths in 90 prisons over 10 years but no space-time clustering among 430 deaths from natural causes in 87 prisons over this period. Model simulations with an imitation rate of 5.8% (CI 1%-11%) reproduced the observed space-time clustering.     

Social anxiety and interpretation of ambiguous smiles

This study investigated whether social anxiety facilitates the discrimination between genuine and ambiguous smiles. Socially anxious (N=20) and nonanxious (N=20) participants categorized as “happy” or “not happy” faces with either (1) a truly happy expression (i.e., happy eyes and a smile), (2) truly nonhappy expressions (e.g., angry eyes and an angry mouth), or (3) blended expressions with a smiling mouth and nonhappy (e.g., angry, sad, etc.) eyes. Results indicated that, relative to nonanxious participants, those high in social anxiety were more likely to judge as “not happy” any blended expression with nonhappy eyes, and they were faster in judging as “not happy” the blended expressions with angry, fearful, or disgusted eyes (but not those with sad, surprised, or neutral eyes). These results suggest, respectively, that social anxiety inhibits a benign interpretation of all the ambiguous expressions with a smile, and speeds up the detection of threatening eyes in such expressions. Importantly, no differences appeared as a function of social anxiety for truly happy or nonhappy faces. This rules out a response-bias explanation, and also reveals that social anxiety does not affect sensitivity in the recognition of prototypical expressions.     

Religion and Spirituality among American Indian,South Asian,Black, Hispanic/Latina,and White Women in the Study on Stress,Spirituality, and Health

Social scientists have increasingly recognized the lack of diversity in survey research on American religion, resulting in a dearth of data on religion and spirituality (R/S) in understudied racial and ethnic groups. At the same time, epidemiological studies have increasingly diversified their racial and ethnic representation, but have collected few R/S measures to date. With a particular focus on American Indian and South Asian women (in addition to Blacks, Hispanic/Latinas, and white women), this study introduces a new effort among religion and epidemiology researchers, the Study on Stress, Spirituality, and Health. This multicohort study provides some of the first estimates of R/S beliefs and practices among American Indians and U.S. South Asians, and offers new insight into salient beliefs and practices of diverse racial/ethnic and religious communities.     

Faith,Race‐Ethnicity,and Public Policy Preferences: Religious Schemas and Abortion Attitudes Among U.S. Latinos

Research has demonstrated that white conservative Protestants are more opposed to abortion than their Catholic counterparts. At the same time, conservative Protestantism has made significant inroads among U.S. Latinos. This study augments existing research on religion and racial‐ethnic variations in abortion attitudes by comparing levels of support for legalized abortion among Catholic and conservative Protestant Latinos. Data are drawn from a nationally representative sample of U.S. Latinos. Significantly greater opposition to abortion is found among religiously devout conservative Protestant Latinos when compared with their Catholic counterparts. Latino Catholicism, which functions as a near‐monopolistic, highly institutionalized faith tradition among Hispanics, produces weaker antiabortion attitudes than those exhibited in Latino conservative Protestantism. Among Latinos, conservative Protestantism operates as a niche voluntaristic faith. These factors produce a religious schema that yields robust antiabortion attitudes. This study has important implications for understanding the intersection of race‐ethnicity, religion, and public policy preferences.     

Neurophysiological differences in reward processing in anhedonics

Anhedonia is characterized by a reduced capacity to experience pleasure in response to rewarding stimuli and has been considered a possible candidate endophenotype in depression and schizophrenia. However, it is still not well understood whether these reward deficits are confined to anticipatory and/or to consummatory experiences of pleasure. In the present study, we recorded electrophysiological responses (event-related brain potentials [ERPs] and oscillatory activity) to monetary gains and losses in extreme groups of anhedonic and nonanhedonic participants. The anhedonic participants showed reduced motivation to incur risky decisions, especially after monetary rewards. These sequential behavioral effects were correlated with an increased sensitivity to punishment, which psychometrically characterized the anhedonic group. In contrast, both electrophysiological measures associated with the impacts of monetary losses and gains—the feedback-related negativity (FRN) and the beta–gamma oscillatory component—clearly revealed preserved consummatory responses in anhedonic participants. However, anhedonics showed a drastic increase in frontal medial theta power after receiving the maximum monetary gain. This increase in theta oscillatory activity could be associated with an increase in conflict and cognitive control for unexpected large positive rewards, thus indexing the violation of default negative expectations built up across the task in anhedonic participants. Thus, the present results showed that participants with elevated scores on Chapman’s Physical Anhedonia Scale were more sensitive to possible punishments, showed deficits in the correct integration of response outcomes in their actions, and evidenced deficits in sustaining positive expectations of future rewards. This overall pattern suggests an effect of anhedonia in the motivational aspects of approach behavior rather than in consummatory processes.     

In the name of honour and freedom: the sacred as a justifying tool for ISIS’ and secular violence

In this paper, I challenge the misconception that ISIS justifies violence in an ontologically Islamic manner. I argue that ISIS and Western secular governments justify violence against each other through the same logic, by resorting to the notion of the sacred. The sacred is a historical and contextually contingent structure of meaning manifested through bipartite sets of cultural forms, informing social practices based on moral and emotional identifications. ISIS appropriates the Islamic sacred forms of Caliphate (legitimate governing authority) and ummah (collective Islamic identity), and projects the latter as humiliated by Western hegemony; ISIS calls upon Muslims to engage in violence in order to gain honour and recognition. In Western secular states the public sphere is a sacred space and popular sovereignty is the secular collective identity; they justify violence against ISIS as the defence of freedom from ISIS’ alleged barbarity and uncivility.     

Web-Based Intervention for Returning Veterans with Symptoms of Posttraumatic Stress Disorder and Risky Alcohol Use

A substantial number of military personnel who have served in Iraq (Operation Iraqi Freedom; OIF) and Afghanistan (Operating Enduring Freedom; OEF) develop symptoms of posttraumatic stress disorder (PTSD) in response to their military experiences and many of these same individuals will drink in a risky or problematic manner following deployment. If left untreated, PTSD symptoms and alcohol problems can become chronic and have a significant, negative impact on the lives of veterans, their families and communities. Further, OIF and OEF service members are often reluctant to seek treatment for mental health symptoms or alcohol problems secondary to stigma. In order to reach this population it is essential that new strategies and venues for delivering evidence-based care are explored. Web-based interventions are uniquely suited to this cohort of veterans in that they have the potential to reach a significant number of veterans who commonly use the Web and who might not otherwise receive care. This article will review the prevalence of PTSD and alcohol problems among OIF and OEF veterans, common barriers they experience with accessing care in traditional mental health settings, and what is known about the effectiveness of Web-based approaches for PTSD and alcohol problems. It also describes the components of a new Web-based intervention, developed by the authors, that uses motivational enhancement and cognitive-behavioral strategies to intervene with returning veterans who report PTSD symptoms and problem drinking. Recommendations for future directions in working with returning veterans with PTSD and alcohol problems will be offered.
