Becoming and Un-becoming: the theory and practice of Anatta

Notions of kinship within systems of rebirth challenge the dominant Euro-American view of kinship as fundamentally biology-centred. By reading across the domains of religion and kinship in Burma, this article will show that what substance is, as well as does, is not self-evident, and thereby reorient the analysis of substance. Furthermore, it will show that it is in the movement of spiritual essences, rather than biogenetic items, that the continuity of each living being’s existence is sought in Burma. Thus, kinship relations are shaped, not necessarily by biology, but by religious and spiritual views of existence.     

ROCs in Eyewitness Identification: Instructions versus Confidence Ratings

From the perspective of signal detection theory, different lineup instructions may induce different levels of response bias. If so, then collecting correct and false identification rates across different instructional conditions will trace out the receiver operating characteristic (ROC)—the same ROC that, theoretically, could also be traced out from a single instruction condition in which each eyewitness decision is accompanied by a confidence rating. We tested whether the two approaches do in fact yield the same ROC. Participants were assigned to a confidence rating condition or to an instructional biasing condition (liberal, neutral, unbiased, or conservative). After watching a video of a mock crime, participants were presented with instructions followed by a six‐person simultaneous photo lineup. The ROCs from both methods were similar, but they were not exactly the same. These findings have potentially important policy implications for how the legal system should go about controlling eyewitness response bias.Copyright © 2017 John Wiley & Sons, Ltd.     

A nitric oxide-independent and beta-adrenergic receptor-sensitive form of metaplasticity limits theta-frequency stimulation-induced LTP in the hippocampal CA1 region

The induction of long-term potentiation (LTP) and long-term depression (LTD) at excitatory synapses in the hippocampus can be strongly modulated by patterns of synaptic stimulation that otherwise have no direct effect on synaptic strength. Likewise, patterns of synaptic stimulation that induce LTP or LTD not only modify synaptic strength but can also induce lasting changes that regulate how synapses will respond to subsequent trains of stimulation. Collectively known as metaplasticity, these activity-dependent processes that regulate LTP and LTD induction allow the recent history of synaptic activity to influence the induction of activity-dependent changes in synaptic strength and may thus have an important role in information storage during memory formation. To explore the cellular and molecular mechanisms underlying metaplasticity, we investigated the role of metaplasticity in the induction of LTP by υ-frequency (5-Hz) synaptic stimulation in the hippocampal CA1 region. Our results show that brief trains of υ-frequency stimulation not only induce LTP but also activate a process that inhibits the induction of additional LTP at potentiated synapses. Unlike other forms of metaplasticity, the inhibition of LTP induction at potentiated synapses does not appear to arise from activity-dependent changes in NMDA receptor function, does not require nitric oxide signaling, and is strongly modulated by β-adrenergic receptor activation. Together with previous findings, our results indicate that mechanistically distinct forms of metaplasticity regulate LTP induction and suggest that one way modulatory transmitters may act to regulate synaptic plasticity is by modulating metaplasticity.     

Complementary nature of heat production and heat intake during behavioral thermoregulation in the rat

Rats were trained to work for radiant heat in a cold environment in an apparatus that permitted the simultaneous measurement of metabolic heat production. Reductions in behavioral efficacy produced either by a decrease in reward duration or intensity or by an increase in response effort resulted in a reduction in behavioral heat intake, an increase in metabolic heat production, and no change in body temperature. Thus, autonomic and behavioral temperature regulation interact to produce a constant body temperature.     

The effects of self-focus on attentional biases in social anxiety:An ERP study

Cognitive theories of social anxiety disorder suggest that biased attention plays a key role in maintaining symptoms. These biases include self-focus and attention to socially threatening stimuli in the environment. The goal of this study was to utilize ERPs that are elicited by a change detection task to examine biases in selective attention (i.e., N2pc) and working memory maintenance (i.e., contralateral delay activity; CDA). Additionally, the effect of self-focus was examined using false heart rate feedback. In support of the manipulation, self-focus cues resulted in greater self-reported self-consciousness and task interference, enhanced anterior P2 amplitude and reduced SPN amplitude. Moreover, P2 amplitude for self-focus cues was correlated with reduced task performance for socially anxious subjects only. The difference in P2 amplitude between self-focus and standard cues was correlated with social anxiety independent of depression. As hypothesized, socially anxious participants (n = 20) showed early selection and maintenance of disgust faces relative to neutral faces as indicated by the N2pc and CDA components. Nonanxious controls (n = 22) did not show these biases. During self-focus cues, controls showed marginal evidence of biased selection for disgust faces, whereas socially anxious subjects showed no bias in this condition. Controls showed an ipsilateral delay activity after being cued to attend to one hemifield. Overall, this study supports early and persistent attentional bias for social threat in socially anxious individuals. Furthermore, self-focus may disrupt these biases. These findings and supplementary data are discussed in light of cognitive models of social anxiety disorder, recent empirical findings, and treatment.     

The Relationship between Cultural Values and Political Ideology, and the Role of Political Knowledge

Cultural theory maintains that four worldviews—egalitarianism, individualism, hierarchicalism, and fatalism—can be used to describe people and societies. We examine survey measures of two of those worldviews—egalitarianism and individualism—to understand their relationship with belief systems. Contrary to what one might expect based on the cultural theory literature, we find that people with low levels of political knowledge seem not to have coherent worldviews regarding these issues. In contrast, people with high levels of political knowledge respond to egalitarianism and individualism questions as if they were opposite ends of a single, liberal-conservative continuum, rather than two of four distinct worldviews. We conclude that cultural theory researchers should take account of the influence of political knowledge whenever they investigate worldviews.     

Tipping the scales: Conciliatory behavior and the morality of self-forgiveness

Two studies examined whether conciliatory behavior aids self-forgiveness and whether it does so in part by making it seem more morally appropriate. Participants in Study 1 (n?=?269) completed an offense-recall procedure; participants in Study 2 (n?=?208) imagined a social transgression under conciliatory behavior (yes, no) and receipt of forgiveness (no, ambiguous, yes) conditions. Conciliatory behavior predicted (Study 1) and caused (Study 2) elevated self-forgiveness and increased perceptions of the moral appropriateness of self-forgiveness. Perceived morality consistently mediated the effect of conciliatory behavior on self-forgiveness. Received forgiveness and guilt were considered as additional mechanisms, but received mixed support. Results suggest that conciliatory behavior may influence self-forgiveness in part by satisfying moral prerequisites for self-forgiveness.     

“We don't Talk about that Around Here”: religion,Spirituality and Mental Health in Northern Ireland

Since the early 1970s, Northern Ireland has experienced violent conflict, the boundaries of which are shaped by religious identification. Although the violence has significantly decreased since the late 1990s, its legacy remains. Research evidences a complex relationship between religious and spiritual beliefs and mental well-being, there is a lack of research about how political conflict, in which religion plays a dominant role, may shape how beliefs may shape the impact of faith on mental health. This article draws upon the views and experiences of mental health service users’ from a qualitative study about religion, spirituality, mental health and social work practice. Participants’ accounts state that while the role of religion and spirituality within mental health was recognised, its exploration was marked with questions of legitimacy. This article proposes that support is needed for service users to both acknowledge this aspect of their mental well-being and promote their having choice about its inclusion in their mental health care.
