Confidence can dissociate from perceptual accuracy, suggesting distinct computational and neural processes underlie these psychological functions. Recent investigations have therefore sought to experimentally isolate metacognitive processes by creating conditions where perceptual sensitivity is matched but confidence differs (“matched-performance / different-confidence”; MPDC). Despite these endeavors’ success, much remains unknown about MPDC effects and how to best harness them in experimental settings. Here we developed a principled approach to comprehensively characterizing MPDC effects through analyzing metaperceptual (i.e., type 2 psychometric) functions relating objective (...) performance to subjective confidence across widely varying performance levels and experimental manipulations. We found that MPDC effect magnitude depends on stimulus properties, observers’ sensitivity level, and critically on trial type order (blocked or interleaved across stimulus property variations). Our findings provide the first comprehensive exploration of MPDC effects, offer a prescriptive guide to metaperceptual analysis, and suggest optimal experimental paradigms for experimentally isolating metacognition and awareness in future studies.

This book provide a unique glimpse into the lives and thinking of famous yoga masters through their correspondance with Dr. Harry Dickman.

Last year, more than seven million Americans participated in yoga or tai chi classes.Yet despite its popularity the real nature of yoga remains shrouded in mystery. A diverse range of practitioners range from white-bearded Indian mystics to celebrities like Madonna and Gwyneth Paltrow. Positioning Yoga provides an overview of the development of yoga, from its introduction to Western audiences by the Indian Swami Vivekananda at the 1893 Parliament of the World's Religions in Chicago to forms of modern practice. What makes (...) yoga practitioners affiliated with Swami Sivananda's Divine Life Society of Rishikesh, India unique--whether they hail from Indian, North America, or Europe? What values around the world have supported the surging popularity of yoga over the past century? This absorbing book considers how lifestyle values have made yoga a global industry and shows how this popular "lifestyle" is produced and disseminated across boundaries. (shrink)

This is the first book to address the social organisation of modern yoga practice as a primary focus of investigation and to undertake a comparative analysis to explore why certain styles of yoga have successfully transcended geographical boundaries and endured over time, whilst others have dwindled and failed. Using fresh empirical data of the different ways in which posture practice was disseminated transnationally by Krishnamacharya, Sivananda and their leading disciples, the book provides an original perspective. The author draws upon extensive (...) archival research and numerous fieldwork interviews in India and the UK to consider how the field of yoga we experience today was shaped by historic decisions about how it was transmitted. The book examines the specific ways in which a small group of yogis organised their practices and practitioners to popularise their styles of yoga to mainstream audiences outside of India. It suggests that one of the most overlooked contributions has been that of Sivananda Saraswati (1887-1963) for whom this study finds his early example acted as a cornerstone for the growth of posture practice. Outlining how yoga practice is organised today on the world stage, how leading brands fit into the wider field of modern yoga practice and how historical developments led to a mainstream globalised practice, this book will be of interest to researchers in the field of Yoga Studies, Religious Studies, Hindu Studies, South Asian History, Sociology and Organisational Studies.

* Hatha yoga is commonly thought to be a pure, ancient Indian spiritual discipline that transcends cultural, temporal and spatial boundaries or a spiritual discipline corrupted by Indians (for export) or Westerners (for import) to accommodate Westerners. Calling these beliefs into question, Max Popov's Radiant Bodies shows how hatha yoga was transformed from sacred practice into a health and fitness regime for middle-class Indians in India in the early and mid-20th century. Popov tells the story of this transformation through the (...) lives and accomplishments of eleven key figures: six Indian yogis (Shri Yogendra, Swami Kuvalayananda, S. Sundaram, T. Krishnamacharya, Swami Sivananda and B. K. S. Iyengar), an Indian bodybuilder (K. V. Iyer), a rajah (Bhavanarao Shrinivasrao), an Indian diplomat (Apa Pant), an American-born English journalist (Louise Morgan), and a Russian-born yogi trained in India (Indra Devi).Their accomplishments are placed within the context of such Western trends as the physical culture movement, the commodification of exercise, militant nationalism, post-World War I anxiety, the mystique of science, jazz age popular entertainment, and the quest for youth and beauty. Through a series of biographical narratives placed in a rich cultural context, Popov not only brings to life the formation of modern hatha yoga as an exercise system in the early 20th century but also its transformation over the course of the 20th century into an embodied spiritual practice. Popov draws on extensive research from rare primary sources to present a cutting edge interpretation of the history of modern hatha yoga. Radiant Bodies is a thoughtful book for the educated general reader that would also be of special interest for religion scholars and yoga professionals and practitioners. (shrink)

This essay is a first attempt to trace the evolution of biographical accounts of Appayya Dīkṣita from the sixteenth century onward, with special attention to their continuities and changes. It explores what these rich materials teach us about Appayya Dīkṣita and his times, and what lessons they offer about the changing historical sensibilities in South India during the transition to the colonial and postcolonial eras. I tentatively identify two important junctures in the development of these materials: one that took place (...) in the first generation to be born after his death, when the idea of him as an avatar of Śiva was introduced, and another at the end of the nineteenth century and the beginning of the twentieth, when many new stories about his encounters with his colleagues and students surfaced. The essay follows a set of themes and tensions that pertain to Appayya Dīkṣita’s social and political affiliations, his sectarian agendas, and the geographic sphere of his activities. These themes and tensions are closely related and prove to be surprisingly resilient, despite the many changes that occurred during the five centuries of recollection that this essay sketches. This overall coherence, I argue, is integral to Appayya Dīkṣita’s sociopolitical context and self-chosen identity. (shrink)
