Testing attitudes,social desirability and behavioral regulations as moderators of implicit-explicit exercise discrepancies: A replication study in Iranian students

IntroductionThere is mixed evidence regarding moderators of the relationship between implicitly and explicitly measured constructs. This study examined this issue with evaluations of exercise relative to health or appearance in a sample of Iranian adolescents. Investigaing automatic associations and reflective constructs might provide important implications for developing interventions targeting exercise behavior in a population with different cultural, social, and economic barriers to exercise than European or North American adolescents.MethodsParticipants were 471 students enrolled in grades 9 to 12, of whom 269 (54.9%) were female. Behavioral regulations, explicit attitudes, and social desirability were investigated as possible moderators. All students completed questionnaire measures of physical activity behavior, attitudes, social desieality and behavioral regulation. They also completed two Go/No Go Association tasks to measure automatic associations of exercise with health and apperarance.ResultsAttitude was a significant moderator of discrepancies between automatic associations of exercise with health and health motives. Interjected regulation moderated implicit-explicit appearance discrepancies. Participants with low social desirability and negative automatic appearance associations had the highest appearance motivation.ConclusionsParticipants focused on the potential of achieving positive health outcomes of exercise rather than physical appearance outcomes, which differs from research from other countries. It is possible that, health was strongly linked with exercise by the pervasive societal pressures in Iran to have a healthy body.     

CHANGING THE PAST: RETROCAUSALITY AND NARRATIVE CONSTRUCTION

Abstract: This article is a reply to Jeanne Peijnenburg's argument for retrocausality in “Shaping Your Own Life.” Although it is perfectly possible to make sense of the way Peijnenburg deals with the subject of changing the past, there is no need to think this implies retrocausality.     

Pupillometric decoding of high-level musical imagery

Humans report imagining sound where no physical sound is present: we replay conversations, practice speeches, and “hear” music all within the confines of our minds. Research has identified neural substrates underlying auditory imagery; yet deciphering its explicit contents has been elusive. Here we present a novel pupillometric method for decoding what individuals hear “inside their heads”. Independent of light, pupils dilate and constrict in response to noradrenergic activity. Hence, stimuli evoking unique and reliable patterns of attention and arousal even when imagined should concurrently produce identifiable patterns of pupil-size dynamics (PSDs). Participants listened to and then silently imagined music while eye-tracked. Using machine learning algorithms, we decoded the imagined songs within- and across-participants following classifier-training on PSDs collected during both imagination and perception. Echoing findings in vision, cross-domain decoding accuracy increased with imagery strength. These data suggest that light-independent PSDs are a neural signature sensitive enough to decode imagination.     

Healthy Conflict in an Era of Intractability

The essay responds to four critical essays by Rosemary Kellison, Ebrahim Moosa, Joseph Winters, and Martin Kavka on the author’s recent book, Healthy Conflict in Contemporary American Society: From Enemy to Adversary (2018). Parts 1 and 2 work in tandem to further develop my accounts of strategic empathy and agonistic political friendship. I defend these accounts against criticisms that my argument for moral imagination obligates oppressed people to empathize with their oppressors. I argue, further, that healthy conflict can be motivated by a kind of “secular” love. This enables my position to immanently critique and mediate the claims that one must either love (agapically) one’s opponent in order to engage them in “healthy conflict,” on one hand, or that one must vanquish, exclude, or “cancel” one’s opponent, on the other. In Part 3, I demonstrate how my account mediates the challenge of an alleged standing opposition between moral imagination and socio-theoretical critique. I defend a methodologically pragmatist account of immanent prophetic criticism, resistance, and conflict transformation. Finally, I respond to one critic’s vindication of a strong enemy/adversary opposition that takes up the case of white supremacist violence in the U.S. I argue that the time horizon for healthy conflict must be simultaneously immediate and also long-term, provided that such engagements remain socio-critically self-reflexive and seek to cultivate transformational responses.     

The Virtues of Metaphysics: A Review of Iris Murdoch's Philosophical Writings

Iris Murdoch's moral philosophy has long influenced contemporary ethics, yet it has not, in general, received the kind of sustained critical attention that it deserves. Existentialists and Mystics and Metaphysics as a Guide to Morals provide new access to most of Murdoch's philosophical writings and make possible a deeper appreciation of her contribution to current thought. After assessing the recent critical reception of Murdoch's thought, this review places her moral philosophy in the context of contemporary trends in ethics by tracing her influence on the work of Charles Taylor, highlights the distinctive features of her moral philosophy (especially her analysis of consciousness), and suggests future directions for Murdochian ethics.     

AXIOLOGY, SELF-DECEPTION, AND MORAL WRONGDOING IN BLAISE PASCAL'S PENSÉES

Blaise Pascal is highly regarded as a religious moralist, but he has rarely been given his due as an ethical theorist. The goal of this article is to assemble Pascal's scattered thoughts on moral judgment and moral wrongdoing into an explicit, coherent account that can serve as the basis for further scholarly reflection on his ethics. On my reading, Pascal affirms an axiological, social-intuitionist account of moral judgment and moral wrongdoing. He argues that a moral judgment is an immediate, intuitive perception of moral value that we willfully disregard in favor of the attractive, though self-deceptive, deliverances of our socially constructed imaginations. We can deceive ourselves so easily because our capacity to evaluate goods is broken, a dark legacy of the fall. In the article's concluding section, I briefly compare Pascal to contemporary ethicists and suggest directions for future research.     

Reliable change in neuropsychological test scores is associated with brain atrophy in older adults

The reliable change index (RCI) is a commonly used method for interpreting change in neuropsychological test scores over time. However, the RCI is a psychometric method that, to date, has not been validated against neuroanatomical changes. Longitudinal neuroimaging and neuropsychological data from baseline and one-year follow-up visits were retrieved from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) database. The RCI was used to identify participants showing reliable decline on memory (ADNI-Mem; N = 450) and executive functioning (ADNI-EF; N = 456) factor scores. For each factor score, two groups (reliable change vs. no reliable change) were matched on potential baseline confounding variables. Longitudinal neuroanatomical data were analysed using tensor-based morphometry. Analysis revealed that reliable change on ADNI-Mem was associated with atrophy in the medial temporal cortex, limbic cortex, temporal lobe and some regions of the parietal lobe. Similar atrophy patterns were found for reliable change on ADNI-EF, except that atrophy extended to the frontal lobe and the atrophy was more extensive and of higher magnitude. The current study not only validates clinical usage of the RCI with neuroanatomical evidence of associated underlying brain change but also suggests patterns of likely brain atrophy when reliable cognitive decline is detected.     

Mental imagery and fiction

Fictions evoke imagery, and their value consists partly in that achievement. This paper offers analysis of this neglected topic. Section 2 identifies relevant philosophical background. Section 3 offers a working definition of imagery. Section 4 identifies empirical work on visual imagery. Sections 5 and 6 criticize imagery essentialism, through the lens of genuine fictional narratives. This outcome, though, is not wholly critical. The expressed spirit of imagery essentialism is to encourage philosophers to ‘put the image back into the imagination’. The weakened conclusion is that while an image is not essential to imagining, it should be returned to our theories of imagination.
