Associations Among Smoking,Anhedonia, and Reward Learning in Depression

Depression and cigarette smoking co-occur at high rates. However, the etiological mechanisms that contribute to this relationship remain unclear. Anhedonia and associated impairments in reward learning are key features of depression, which also have been linked to the onset and maintenance of cigarette smoking. However, few studies have investigated differences in anhedonia and reward learning among depressed smokers and depressed nonsmokers. The goal of this study was to examine putative differences in anhedonia and reward learning in depressed smokers (n = 36) and depressed nonsmokers (n = 44). To this end, participants completed self-report measures of anhedonia and behavioral activation (BAS reward responsiveness scores) and as well as a probabilistic reward task rooted in signal detection theory, which measures reward learning (Pizzagalli, Jahn, & O'Shea, 2005). When considering self-report measures, depressed smokers reported higher trait anhedonia and reduced BAS reward responsiveness scores compared to depressed nonsmokers. In contrast to self-report measures, nicotine-satiated depressed smokers demonstrated greater acquisition of reward-based learning compared to depressed nonsmokers as indexed by the probabilistic reward task. Findings may point to a potential mechanism underlying the frequent co-occurrence of smoking and depression. These results highlight the importance of continued investigation of the role of anhedonia and reward system functioning in the co-occurrence of depression and nicotine abuse. Results also may support the use of treatments targeting reward learning (e.g., behavioral activation) to enhance smoking cessation among individuals with depression.     

Identity,Incentives, and Religious Defense of Human Rights: Marshall Meyer and the DAIA in Argentina's Dirty War

Whether religious groups advance or limit human rights has been a topic of recent debate among human rights scholars. This article studies the conditions under which religious leaders advance human rights in the context of Argentina's Jewish community during the country's 1976–1983 military dictatorship. Three major influences on religious support for human rights—autonomy from a religious community's establishment, a missionary-reformer identity, and congregational mobilization—are highlighted. Original archival research from the papers of U.S.-born rabbi Marshall T. Meyer illustrates his defense of human rights in Argentina, contrasting his work with the inaction of a major established Jewish organization. Quantitative cross-national analysis extends the case study findings by showing a relationship between religious institutions’ autonomy from the state and defense of human rights.     

How do psychosocial challenges associated with living with congenital heart disease translate into treatment interests and preferences? A qualitative approach

Objectives: There is an increasing amount of research being conducted regarding the psychosocial challenges associated with living with congenital heart disease (CHD), however little is known about how these challenges influence the type of psychosocial services patients want. This study investigated (1) the type of services patients want; (2) how they want to access these services; and (3) why they want these services. Methods: Three focus groups with adults with CHD (total of 14 participants aged 19-67) were conducted and thematic analysis was used to identify emerging themes. Results: Participants described wanting to access specific psychosocial services in three broad categories (counselling, connecting with other adults with CHD and psycho-education) and in three main formats (individual/group therapy, mentorship programmes and patient conferences). Reasons for wanting these services were grouped under two overarching themes, namely intrapersonal factors and interpersonal challenges. Conclusions: Psychosocial challenges are part of the everyday lives of adults with CHD, yet they are rarely addressed as part of routine medical care. Patients themselves have clear opinions regarding the psychological services most appropriate to target their experiences of living with CHD.     

The structure of cognitive abilities in youths with manic symptoms: a factorial invariance study

This study compared the structure of cognitive ability (specifically, verbal/crystallized [Gc] and visual-spatial ability [Gv]), as measured in the Wechsler Intelligence Scale for Children, in youth with manic symptoms with a nationally representative group of similarly aged youth. Multigroup confirmatory factor analysis found the majority of the estimated parameters were invariant between the groups, although there was a difference in the intercepts for the Similarities subtest and difference in unique variances for the Picture Completion, Comprehension, and Picture Arrangement subtests. Thus, although there are many neurological changes associated with manic symptoms, the structure of verbal/crystallized and visual-spatial abilities appear relatively robust and invariant. As Gc and Gv are the primary domains on all the Wechsler Intelligence Scales for Children, results also indicate that clinical interpretation of the Wechsler scales may be appropriate to measure cognitive performance in youths with manic symptoms.     

Uncovering the metaphysics of psychological warfare: The social science behind the Psychological Strategy Board's operations planning, 1951–1953

In April 1951 president Harry S. Truman established the Psychological Strategy Board to enhance and streamline America's sprawling psychological warfare campaign against the USSR. As soon as the Board's staff began work on improving US psychological operations, they wondered how social science might help them achieve their task. Board Director, Gordon Gray, asked physicist turned research administrator Henry Loomis to do a full review of America's social science research program in support of psychological operations. Loomis willingly accepted the task. This paper documents Loomis's investigation into America's social science research program. It uncovers the critical role that government departments had in the creation of research in the early 1950s and thus highlights that the government official is an important actor in the history of social science and the application of social science to psychological operations at the beginning of the Cold War.     

Natural conversations as a source of false memories in children: Implications for the testimony of young witnesses

Research on factors that can affect the accuracy of children’s autobiographical remembering has important implications for understanding the abilities of young witnesses to provide legal testimony. In this article, we review our own recent research on one factor that has much potential to induce errors in children’s event recall, namely natural memory sharing conversations with peers and parents. Our studies provide compelling evidence that not only can the content of conversations about the past intrude into later memory but that such exchanges can prompt the generation of entirely false narratives that are more detailed than true accounts of experienced events. Further, our work show that deeper and more creative participation in memory sharing dialogues can boost the damaging effects of conversationally conveyed misinformation. Implications of this collection of findings for children’s testimony are discussed.     

A randomized controlled pilot study evaluating Worry Less,Live More: The Mindful Way Through Anxiety Workbook

ABSTRACT

Effective interventions for generalized anxiety exist, but barriers to treatment prevent their broad dissemination. Commercially available self-help materials may help bridge this gap, but few have been empirically evaluated. This study compared self-reported change in generalized anxiety symptomology and associated problems between community members with excessive worry who were randomly assigned to receive the Worry Less, Live More: The Mindful Way through Anxiety Workbook (n = 35) and those in a delayed condition (n = 29). Participants in the workbook condition reported significantly greater reductions between baseline and 11-week follow-up in self-reported worry (η ² =.15), general anxiety/tension (η ² =.13), and anxiety (η ² =.24) than those in the delayed condition, although no statistically significant differences across condition on changes in depression, functional impairment or acceptance were detected. This pilot study provides support for continued research examining the efficacy of acceptance-based behavioral therapy delivered in a self-help format.
