Acute stress impairs recognition for positive words--association with stress-induced cortisol secretion

Some studies suggest that stress-induced effects of cortisol on memory are modulated by the valence of the stimuli to be learned and retrieved. The present study investigated the effect of acute stress-induced cortisol secretion on acquisition and retrieval of pleasant, unpleasant and neutral words. Sixty healthy men were randomly assigned to one of the three experimental groups. Participants were either exposed to a standardized laboratory stressor (the Trier Social Stress Test) before learning a wordlist, or before retrieval, or were not stressed. Free recall and recognition were tested 24 h later. Free recall was not affected by stress exposure. For recognition, there was no main effect of the stressor, but a main effect of valence and a valence by group interaction emerged: recognition for positive words was significantly impaired when subjects were stressed before retrieval. In addition, a positive correlation between the cortisol response and errors of commission was found. The results suggest that acute stress impairs memory for positive stimuli and that stress-induced cortisol secretion interferes with accuracy of memory retrieval, i.e. the ability to discriminate true memories from false ones.     

"Frog, where are you?" Narratives in children with specific language impairment, early focal brain injury, and Williams syndrome

In this cross-population study, we use narratives as a context to investigate language development in children from 4 to 12 years of age from three experimental groups: children with early unilateral focal brain damage (FL; N=52); children with specific language impairment (SLI; N=44); children with Williams syndrome (WMS; N=36), and typically developing controls. We compare the developmental trajectories of these groups in the following domains: morphological errors, use of complex syntax, complexity of narrative structure, and types and frequency of evaluative devices. For the children with early unilateral brain damage, there is initial delay. However, by age 10, they are generally within the normal range of performance for all narrative measures. Interestingly, there are few, if any, side specific differences. Children with SLI, who have no frank neurological damage and show no cognitive impairment demonstrate significantly more delay on all morphosyntactic measures than the FL group. Quantitatively, on morphosyntactic measures, the SLI group clusters with those children with WMS who are moderately retarded. Together these data help us to understand the extent and nature of brain plasticity for language development and those aspects of language and discourse that are dissociable.     

Perceived intergroup threat and attitudes of host community members toward immigrant acculturation

The authors expected the extent to which host community members (a) perceive immigrants as threatening, (b) believe that the immigrants are able to assimilate to the host community (permeability), and (c) consider their presence in the host community as legitimate to predict attitudes towards immigrant acculturation. The authors designed Study 1 to examine attitudes of Germans toward Turkish immigrants. Participants were 227 German white-collar and blue-collar workers. As expected, ethnocentric acculturation attitudes positively correlated with perceived threat and negatively correlated with perceived legitimacy and perceived permeability. However, only perceived threat contributed uniquely to the prediction of the attitudes. In Study 2, the authors applied an experimental manipulation of perceived threat. Before answering attitude questions, participants read magazine articles with a threatening, enriching, or irrelevant content. The manipulation had the predicted impact on the self-reported attitudes toward immigrants. However, the salience of threatening or enriching aspects of the Turkish culture did not affect implicitly measured attitudes.

'Consumed By Fire From Within': Teilhard de Chardin's Pan-christic Mysticism In Relation To The Catholic Tradition

Pierre Teilhard de Chardin (1881–1955), eminent Jesuit scientist and religious write, was one of the great Christian mystics of the twentieth century. Yet scholars of mysticism rarely discuss his works or typology of mysticism. I argue that the little studied, early Writings in Time or War , together with his late autobiographical essays, provide the hermeneutical key for understanding Teilhard's pan-christic mysticism. My paper examines especially the experiential and cosmic dimensions of his pan-christic mysticism of union and communion with Christ through all things. This mysticism belongs to the kataphatic rather than apophatic tradition of Christian mysticism. It is deeply rooted in, and in full continuity with, the catholic tradition but through introducing innovative elements, it is at the same time also thoroughly transformative. I show this in relation to Teilhard's understanding of the Spiritual Exercises and, in particular, to that of the "Sacred Heart" whose meaning he greatly extended by understanding it in a universal, cosmic sense. He so frequently used the metaphors of fire and heart—well known, traditional images of Christian mysticism—that I describe Teilhard's mysticism as a fire and heart mysticism. I also discuss the significance of his typology of mysticism in relation to the comparative study of mysticism.     

WHAT SCIENCE CAN AND CANNOT OFFER TO A RELIGIOUS NARRATIVE

Abstract. A molecular/cell biologist offers perspectives on the contributions that the scientific worldview might and might not make to religious though. It is argued that two essential features of institutionalized religions–their historical context and their supernatural orientation—are not addressed by the sciences, nor can the sciences contribute to the art and ritual that elicit states of faith and transcendence. The sciences have, however, important stories (myths) to offer, stories that have the potential to unify us, to tell us what is sacred, what has meaning, and how we might best proceed.     

Religiopoiesis

Religiopoiesis describes the crafting of religion, a core activity of humankind. Each religion is grounded in its myth, and each myth includes a cosmology of origins and destiny. The scientific worldview coheres as such a myth and calls for a religiopoietic response. The difficulties, opportunities, and imperatives inherent in this call are explored, particularly as they impact the working scientist.     

Reflections on Scientific and Religious Metaphor

The importance of scientific conflicts for theology and philosophy is difficult to judge. In many disputes of significance, prominent scientists can be found on both sides. Profound philosophical and religious implications are sometimes said to be implied by the new theory as well. This article examines the dispute over natural selection between Richard Dawkins and Stephen Jay Gould as a contemporary instance of such a conflict. While both claim that profoundphilosophical conclusions flow from their own alternative account of evolution, I suggest that the implication is not as great as is claimed and that the alleged implications have as much to do with their own perceptions of theology as with the actual theories themselves. Nevertheless, evolutionary theory is not irrelevant for theology. Theologians should be aware of the possible implications of evolutionary theory and at the same time the extent and limits of such implications.
