In recent years, multivariate pattern analysis has been hugely beneficial for cognitive neuroscience by making new experiment designs possible and by increasing the inferential power of functional magnetic resonance imaging, electroencephalography, and other neuroimaging methodologies. In a similar time frame, “deep learning” has produced a parallel revolution in the field of machine learning and has been employed across a wide variety of applications. Traditional MVPA also uses a form of machine learning, but most commonly with much simpler techniques based on (...) linear calculations; a number of studies have applied deep learning techniques to neuroimaging data, but we believe that those have barely scratched the surface of the potential deep learning holds for the field. In this paper, we provide a brief introduction to deep learning for those new to the technique, explore the logistical pros and cons of using deep learning to analyze neuroimaging data – which we term “deep MVPA,” or dMVPA – and introduce a new software toolbox intended to facilitate dMVPA for neuroscientists everywhere.

To describe phenomena that occur at different time scales, computational models of the brain must incorporate different levels of abstraction. At time scales of approximately 1/3 of a second, orienting movements of the body play a crucial role in cognition and form a useful computational level embodiment level,” the constraints of the physical system determine the nature of cognitive operations. The key synergy is that at time scales of about 1/3 of a second, the natural sequentiality of body movements can (...) be matched to the natural computational economies of sequential decision systems through a system of implicit reference called deictic in which pointing movements are used to bind objects in the world to cognitive programs. This target article focuses on how deictic bindings make it possible to perform natural tasks. Deictic computation provides a mechanism for representing the essential features that link external sensory data with internal cognitive programs and motor actions. One of the central features of cognition, working memory, can be related to moment-by-moment dispositions of body features such as eye movements and hand movements. (shrink)

The microfinance business model focuses largely on lending to the woman in the household, rather than the man. The belief is that women are more trustworthy borrowers than men, and that lending to women may have increased social impact. Yet in several cases, women do not have control over the loan backed business despite being the borrower of record. Such takeover of the business by the man constitutes an ethical violation. We find that high dependency ratios in the family are (...) correlates of such ethical violations. Further, we also find that ethical violations have a significant economic cost, consistent with prior scholarship in the family-business domain. While access to microfinance increases household welfare, this beneficial impact reduces by over 50% in the presence of an ethical violation. Our results suggest that microfinance lenders need to move beyond the traditional role of just being a lender to providing advice on issues like family planning, and money management, and enforcement, thus moving closer to the solidarity economy paradigm of integrating savings and credit into broader canvases of social relationships and social structures.

A high percent of oxidative energy metabolism is needed to support brain growth during infancy. Unhealthy diets and limited nutrition, as well as other environmental insults, can compromise these essential developmental processes. In particular, iron deficiency anemia has been found to undermine both normal brain growth and neurobehavioral development. Even moderate ID may affect neural maturation because when iron is limited, it is prioritized first to red blood cells over the brain. A primate model was used to investigate the neural (...) effects of a transient ID and if deficits would persist after iron treatment. The large size and postnatal growth of the monkey brain makes the findings relevant to the metabolic and iron needs of human infants, and initiating treatment upon diagnosis of anemia reflects clinical practice. Specifically, this analysis determined whether brain maturation would still be compromised at 1 year of age if an anemic infant was treated promptly once diagnosed. The hematology and iron status of 41 infant rhesus monkeys was screened at 2-month intervals. Fifteen became ID; 12 met clinical criteria for anemia and were administered iron dextran and B vitamins for 1–2 months. MRI scans were acquired at 1 year. The volumetric and diffusion tensor imaging measures from the ID infants were compared with monkeys who remained continuously iron sufficient. A prior history of ID was associated with smaller total brain volumes, driven primarily by significantly less total gray matter and smaller GM volumes in several cortical regions. At the macrostructual level, the effect on white matter volumes was not as overt. However, DTI analyses of WM microstructure indicated two later-maturating anterior tracts were negatively affected. The findings reaffirm the importance of iron for normal brain development. Given that brain differences were still evident even after iron treatment and following recovery of iron-dependent hematological indices, the results highlight the importance of early detection and preemptive supplementation to limit the neural consequences of ID.

The majority of commentators agree that the time to focus on embodiment has arrived and that the disembodied approach that was taken from the birth of artificial intelligence is unlikely to provide a satisfactory account of the special features of human intelligence. In our Response, we begin by addressing the general comments and criticisms directed at the emerging enterprise of deictic and embodied cognition. In subsequent sections we examine the topics that constitute the core of the commentaries: embodiment mechanisms, dorsal (...) and ventral visual processing, eye movements, and learning. (shrink)

Yoga-Sutras of Patanjali is a foundational psychological text that organizes, codifies, and systematically presents in s_tra form the psychology as practised in India around second century BCE. Its theme is to help humans free themselves from their congenital bondage due to conditioned existence and consequent suffering. The goal is to restore the person to her inherent unconditioned blissful being. The quintessence of Yoga is meditation. Meditation consists of dharana and dhyana, a contemplative state of passive attention precipitated by a prolonged (...) practice of concentration. Dhy_na practice leads to sam_dhi, a stand-still altered state in which the mind is controlled and restrained from habitual cognitive processing. This paper provides a theoretical background of Patanjali Yoga and a select review of empirical research on the neurophysiological correlates of meditation, highlighting on the one hand some of its methodological shortcomings and conceptual problems and suggesting on the other hand the areas of promise for further research on meditation.

This book discusses the profound philosophy and practical psychology behind yoga, beyond its popular body-culture aspect. It pays particular attention to the psychological principles involved and their implications for the consummate understanding of human nature. It explores the psychological aspects of yoga theory and practice and discusses the aphorisms in Patanjali's treatise on Yoga with necessary commentary in current psychological terminology to make them intelligible to students of psychology and other interested readers. Importantly, the author draws out the implications of (...) these aphorisms for future psychological study and research. The book discusses the author's concept of yoga of nonviolence which brings in Gandhian ideas into the framework of yoga. The author's own vast experience in creating interfaces of yoga research with practice also informs the discussions in this book. This authoritative and topical book by an eminent academic like Professor Ramakr ishna Rao is of interest to scholars and students of diverse disciplines, including but not limited to psychology, philosophy and wellbeing research.

Although today Appayya Dīkṣīta enjoys a reputation as the preeminent Śaiva polemicist of the sixteenth century, it must be remembered that he also wrote works from a distinctively Vaiṣṇava perspective, in which Viṣṇu is extolled as the paramount god rather than Śiva. This paper examines one of those works, the Varadarājastava and its autocommentary. It places special emphasis on how the poem is patterned on the Varadarājapañcāśat of the fourteenth-century Śrīvaiṣṇava poet and philosopher, Vedānta Deśika, with close attention to the (...) Varadarājastava’s use of the Vaiṣṇava imagery of the dahara-vidyā or meditation on brahman as the small space within the lotus-shaped heart. While this meditation was the central devotional practice for Appayya Dīkṣita and for his Śaiva predecessor Śrīkaṇṭha, in the Varadarājastava, Appayya is able to develop a more overtly Advaita dahara-vidyā, unfettered by hermeneutic fidelity to Śrīkaṇṭha’s Śaiva approach. The paper also considers the anomaly of Appayya writing as a Vaiṣṇava in the context of the institutional conflicts that took place between Śaivas and Vaiṣṇavas at sites close to where Appayya received patronage.

Over the past hundred years, a number of scientific investigators claim to have adduced experimental evidence for phenomena information” seems to behave like a weak signal that has to compete for the information-processing resources of the organism, a reduction of ongoing sensorimotor activity may facilitate ESP detection. Such a meaningful convergence of results suggests that psi phenomena may represent a unitary, coherent process whose nature and compatibility with current physical theory have yet to be determined. The theoretical implications and potential (...) practical applications of psi could be significant, irrespective of the small magnitude of psi effects in laboratory settings. (shrink)

Argues against D. Hume's (1825) treatise "Of Miracles," which is often used to disprove the existence of psi. Hume states that a miracle is a violation of the laws of nature which are proved to be true by common experience, and that the only sufficient testimony for a miracle would be testimony whose falsehood would be even more miraculous than the miracle itself. The primary objections to Hume's argument are that (1) it is tautological, since it presupposes the nonexistence of (...) miraculous events, and (2) as a metaphysical statement, it is inappropriate when considering empirical evidence, which should be judged by its own rule.

Advaita, a non-dualist system of Vednta philosophy, and Yoga, a dualist system of classical Indian philosophy, make different ontological assumptions. Yet surprisingly they subscribe to similar views on many psychological issues. Together they provide the base for what is now known as Indian psychology. As an alternate system of psychology, it provides fruitful models that go well beyond the currently dominant reductionist postulates in cognitive science and suggest attractive programmes of research for those working in areas of cognitive excellence and (...) extraordinary human abilities. This paper provides an outline of a model derived from Indian psychology called the Body-Mind-Consciousness Trident model which favours a process view of reality, in place of entity metaphysics.

This authoritative volume, written by two well-known psychologist-philosophers, presents a model of the person and its implications for psychological theory and practice. Professors Ramakrishna Rao and Anand Paranjpe draw the contours of Indian psychology, describe the methods of study, explain crucial concepts, and discuss the central ideas and their application, illustrating them with insightful case studies and judicious reviews of available research data and existing scholarly literature. The main theme is organized around the thesis that psychology is the study of (...) the person and that the person is a unique composite of body, mind and consciousness. The goal of the person is self-realization. Self-realization consists in the realization of one's true self as distinct from the manifest ego and it is facilitated by cultivating consciousness. Cultivating consciousness leads to a kind of psycho-spiritual symbiosis resulting in personal transformation, altruistic value orientation and flowering of the hidden human potential. (shrink)

Meiotic recombination occurs preferentially at certain regions called hot spots and is important for generating genetic diversity and proper segregation of chromosomes during meiosis. Hot spots have been characterized most extensively in yeast, mice and humans. The development of methods based on sperm typing and population genetics has facilitated rapid and high‐resolution mapping of hot spots in mice and humans in recent years. With increasing information becoming available on meiotic recombination in different species, it is now possible to compare several (...) molecular features associated with hot‐spot loci. Further, there have been advances in our knowledge of the factors influencing hot‐spot activity and the role that they play in structuring the genome into haplotype blocks. We review the molecular features associated with hot spots in terms of their properties and mechanisms underlying their function and distribution. A large number of these features seem to be shared among hot spots from different species suggesting common mechanisms for their formation and function.

Perception is sensory awareness. Cognition is reflective awareness. Consciousness is awareness-as-such. In Indian psychology, as represented by Samkhya-Yoga and Advaita Vedanta systems, consciousness and mind are fundamentally different. Reality is the composite of being (sat), knowing (cit) and feeling (ananda). Consciousness is the knowledge side of the universe. It is the ground condition of all awareness. Consciousness is not a part or aspect of the mind. Mind is physical and consciousness is not. Consciousness does not interact with the mind, the (...) brain or any other physical objects or processes. Nor does it have any causative role in mental activity. Hence the existence of consciousness does not interfere or upset the apparently closed physical system. Mind in this view is the interfacing instrumentality that faces consciousness on one side and the brain and the rest of the physical world on the other. Mind is closely connected with the different systems of the brain. In normal perceptions, the mind takes the forms of objects via the channels of the sensory system and the processes in the brain. The forms themselves are non-conscious representations of the world of objects. The mental forms (vrittis) become conscious experiences in the light of the purusha. The vritti in sensory form is perception and with the reflection of the purusha it becomes cognition. All conscious perceptions are therefore cognitions. (shrink)

Two dominant perspectives on consciousness representing the eastern and the western viewpoints are discussed. In the western scholarly tradition, consciousness is generally equated with the mind; intentionality is regarded as its defining characteristic; and the goal is one of seeking rational understanding of what consciousness/mind is. In the eastern tradition, as represented by the Indian approach to the study of consciousness, consciousness and mind are considered to be different; consciousness as such is believed to be nonintentional while the mind is (...) regarded as intentional; and the goal is one of developing practical methods for transformation of the human condition via realization of consciousness as such. It is suggested that consciousness encompasses two different domains, the transcendental and the phenomenal, and that humans enjoy dual citizenship in them. The eastern and western viewpoints each seems to be directed more toward one domain than the other, resulting in a biased emphasis. Seen as complementary rather than in opposition to each other, the eastern and the western perspectives may give us a more comprehensive understanding of consciousness and its role in our being.
