Effects of a self-regulation intervention on exercise are moderated by depressive symptoms: A quasi-experimental study

This study investigated whether a computer-based self-regulation intervention increases physical exercise in individuals with or without depressive symptoms. A total of 361 individuals in orthopedic rehabilitation, 36 of them with depressive symptoms, were recruited in Germany. In a quasi-experimental study, individuals were allocated to either a computer-based self-regulation intervention or an online questionnaire. Exercise was measured at the beginning of rehabilitation and six weeks after rehabilitation. Depressive symptoms were assessed at the end of rehabilitation. An analysis of covariance was conducted, controlling for exercise baseline, sex, and phase of assessment. A main effect for depressive symptoms (p = .005) and intervention group (p = .011), as well as a marginal interaction of intervention x depressive symptoms were found (p = .076). Results indicate that the self-regulation exercise intervention in an orthopedic rehabilitation setting seem to be only effective in non-depressed individuals. Future research should examine how health behavior change programs can be designed more effectively for individuals with depressive symptoms.     

Deconstructing Frith and Snowling's homograph-reading task: Implications for autism spectrum disorders

The poor performance of autistic individuals on a test of homograph reading is widely interpreted as evidence for a reduction in sensitivity to context termed “weak central coherence”. To better understand the cognitive processes involved in completing the homograph-reading task, we monitored the eye movements of nonautistic adults as they completed the task. Using single trial analysis, we determined that the time between fixating and producing the homograph (eye-to-voice span) increased significantly across the experiment and predicted accuracy of homograph pronunciation, suggesting that participants adapted their reading strategy to minimize pronunciation errors. Additionally, we found evidence for interference from previous trials involving the same homograph. This progressively reduced the initial advantage for dominant homograph pronunciations as the experiment progressed. Our results identify several additional factors that contribute to performance on the homograph reading task and may help to reconcile the findings of poor performance on the test with contradictory findings from other studies using different measures of context sensitivity in autism. The results also undermine some of the broader theoretical inferences that have been drawn from studies of autism using the homograph task. Finally, we suggest that this approach to task deconstruction might have wider applications in experimental psychology.     

Treatment of Chronic Major Depression Using the Cognitive Behavioral Analysis System of Psychotherapy (CBASP)

This article presents data from an ABAB single case design study of a 60-year-old Caucasian male diagnosed with chronic major depressive disorder. The Cognitive Behavioral Analysis System of Psychotherapy (CBASP) was utilized throughout treatment, and both BDI scores and diagnostic interviews revealed states of partial, and ultimately full remission during the course of treatment. A focus was ultimately placed on generalizing what the patient learned in-session to his outside life. Additionally, the unique design of this case illustrated that the patient experienced a moderate reduction in depressive symptoms, prior to the long-term alteration of his coping style. A stable change in his coping style was necessary before full and sustained recovery was evidenced.     

Interfaith Dialogue and the Science-and-Religion Discussion

The science-and-religion dialogue has so often assumed that the key issues for discussion are those that have arisen within the Western Christian religious and intellectual tradition that little interest has been devoted to the possible insights that the presence of non-Christian voices in the dialogue might bring. In the following I explore the benefits of a truly multireligious dialogue on science and religion and offer a model for integrating various religious perspectives into the science-and-religion dialogue. Of course, taking the multifaith perspectives of the religions seriously also means making a dialogue between religions a component of the science-and-religion dialogue, and I discuss how such a dialogue might unfold along with key ideas that might emerge in ever more interesting ways once the dialogue begins.     

Natural Selection and Design: Comments on Michael Ruse's New Book

Is the adaptive complexity of living organisms the result of evolutionary processes alone? or does it give evidence of intentional design? Michael Ruse appears to argue that we can have it either way. As a scientist I find the argument from design unnecessary. Yet it has great appeal to humans, whose behavior is largely intentional and who look for patterns in events and for the intentions that may have produced them.     

From Noosphere to Theosphere: Cyclotrons, Cyberspace, and Teilhard's Vision of Cosmic Love

Two theme–setting quotations introduce this essay—that of Yeats's falcon, deaf to the falconer's call, adrift in space above the blood–dimmed tide, counterpoised to Pierre Teilhard de Chardin's call to abandon old nationalistic prejudices and build the earth. With primary references to the thought of Teilhard, along with, among others, to Ewert Cousins, Andrew M. Greeley, Karl Jaspers, Marshall McLuhan, Ilya Prigogine, Karl Rahner, Leonard Swidler, David Tracy, and Alfred North Whitehead, I argue that the most crucial intellectual paradigm shift of the twenty–first century will challenge humanity to take the turn from uncritical attachment to rigid absolutism or atomistic fragmentation toward a sense of open–ended, off–centered centeredness and fluid connections—from a static to a dynamic model of reality. Central to my argument is the Teilhardian reinterpretation of the Christian metaphors of creation, fall, incarnation, salvation, and the eschaton in the evolutionary terms of the emergence of cosmic consciousness from the chrysalis of the world of the past—from chaos to order, from biosphere via noosphere to theosphere. Facilitated by the exponential growth of populations, collaborative research, science, technology, and global communication (most dramatically manifested by the Internet), this emergent understanding of what it means to be human can, first, foster the awareness that in humanity evolution has become conscious of itself, and then, gradually, precipitate the formation of “the global village” (the mystical body of Christ), as respectful dialogue replaces diatribe and the dualistic pugilism of Samuel Huntington's “Clash of Civilizations” is gradually transformed into a nonadversarial mentality that values shared humanity and a common purpose. Thus, eons hence, empowered by love–energy, the transmutation of the human into the ultra–human can take the ultimate quantum leap into a yet higher dimension where spirit/energy is no longer in need of flesh/mass, and Earth can be safely left behind.     

New Evolutionary Perspectives on Altruism: Multilevel-Selection and Costly-Signaling Theories

Social psychological theories tend to be primarily concerned with the immediate causes of altruism, whereas evolutionary explanations focus more on the origins and ultimate functions of altruistic behavior. Recent developments in the evolutionary psychology of altruism promise an even richer understanding of this important category of social behaviors. Specifically, new perspectives offered by multilevel-selection theory and costly-signaling theory may help to shed light on some of the more problematic issues in the study of altruism.     

Evolutionary Psychology of Facial Attractiveness

The human face communicates an impressive number of visual signals. Although adults' ratings of facial attractiveness are consistent across studies, even cross-culturally, there has been considerable controversy surrounding attempts to identify the facial features that cause faces to be judged attractive or unattractive. Studies of physical attractiveness have attempted to identify the features that contribute to attractiveness by studying the relationships between attractiveness and (a) symmetry, (b) averageness, and (c) nonaverage sexually dimorphic features (hormone markers). Evolutionary psychology proposes that these characteristics all pertain to health, suggesting that humans have evolved to view certain features as attractive because they were displayed by healthy individuals. However, the question remains how single features that are considered attractive relate to each other, and if they form a single ornament that signals mate quality. Moreover, some researchers have recently explained attractiveness preferences in terms of individual differences that are predictable. This article briefly describes what is currently known from attractiveness research, reviews some recent advances, and suggests areas for future researchers' attention.
