    Observing entrainment in music performance: video-based observational analysis of Indian musicians’ tanpura playing and beat marking

    Get PDF
     Entrainment has been suggested as an important phenomenon underlying aspects of musical behaviour, and is attracting increasing attention in music psychology (see e.g. Large and Jones, 1999; Large, 2000), and in ethnomusicology (Clayton, Sager and Will, 2005). Approaches to its study in ethnomusicology must address a significant methodological problem: how to study entrainment phenomena in an ecologically valid manner, and to integrate this process into a programme of ethnographic research. Video recordings contain important data regarding the physical movements of participants in musical events (as well as their audible results), and through the application of observational analysis software these recordings can form the basis of studies of entrainment between different quasi-periodic musical processes as manifested in movement patterns. For the present study a short video clip of an Indian raga performance was selected (taken from a performance of Shree Rag by the singer Veena Sahasrabuddhe). Observational analysis was carried out using The Observer Video-Pro software, configured to record the plucking of tanpura strings and performers' beat markers (hand or finger taps). Time series data thus generated were analysed using calculations of phase relationships, revealing several instances of both self- and interpersonal entrainment (the stated intention of the performers is, on the contrary, that the tanpura rhythms should each proceed independently). Entrainment between these behaviours points to a complex, but unintended form of emergent order. This unexpected result demonstrates the usefulness of this method in revealing otherwise unnoticed phenomena in musical performance, and raises important questions for future research

    The role of prediction in social neuroscience

    Get PDF
    Research has shown that the brain is constantly making predictions about future events. Theories of prediction in perception, action and learning suggest that the brain serves to reduce the discrepancies between expectation and actual experience, i.e., by reducing the prediction error. Forward models of action and perception propose the generation of a predictive internal representation of the expected sensory outcome, which is matched to the actual sensory feedback. Shared neural representations have been found when experiencing one's own and observing other's actions, rewards, errors, and emotions such as fear and pain. These general principles of the “predictive brain” are well established and have already begun to be applied to social aspects of cognition. The application and relevance of these predictive principles to social cognition are discussed in this article. Evidence is presented to argue that simple non-social cognitive processes can be extended to explain complex cognitive processes required for social interaction, with common neural activity seen for both social and non-social cognitions. A number of studies are included which demonstrate that bottom-up sensory input and top-down expectancies can be modulated by social information. The concept of competing social forward models and a partially distinct category of social prediction errors are introduced. The evolutionary implications of a “social predictive brain” are also mentioned, along with the implications on psychopathology. The review presents a number of testable hypotheses and novel comparisons that aim to stimulate further discussion and integration between currently disparate fields of research, with regard to computational models, behavioral and neurophysiological data. This promotes a relatively new platform for inquiry in social neuroscience with implications in social learning, theory of mind, empathy, the evolution of the social brain, and potential strategies for treating social cognitive deficits

    The Magnificent Seven: a Narrative Analysis of Suppressed Discourses in Psychiatric Diagnoses

    Get PDF
    This study is a Narrative Analysis of the hidden strengths and positive qualities inherent to identified psychiatric diagnosis. Seven individuals were interviewed on two occasions and also corresponded with me via email and telephone. Analysis of individual narratives yielded common thematic elements and common plot points, these factors were further analyzed and contemplated in the light of their implications for the Counseling profession. an informed critique of the research design is presented, followed by implications and suggestions for future research

    Flux Variation of Cosmic Muons

    In the current paper, we analyzed the variation of cosmic radiation flux with elevation, time of the year and ambient temperature with the help of a portable cosmic muon detector, the construction of which was completed by a team from Southern Arkansas University (SAU) at Lawrence Berkeley National Laboratory (LBNL). Cosmic muons and gamma rays traverse two synchronized scintillators connected to two photomultiplier tubes (PMT) via light guides, and generate electronic pulses which we counted using a Data Acquisition Board (DAQ). Because muons are the product of collisions between high-energy cosmic rays and atmospheric nuclei, and therefore shower onto earth, the scintillators were arranged horizontally for detection. The elevation measurements were recorded at different locations, starting from 60 feet below sea-level at the Underground Radiation Counting Laboratory at Johnson Space Center, TX, to 4200 feet at Mt. Hamilton, CA. Intermediate locations included sea-level Galveston Bay, TX, and Mt. Magazine, AR (2800 feet). The data points showed a noticeable increase in flux as elevation increases, independent of latitude. Measurements investigating the dependence of cosmic rays on temperature and time of the year took place locally in Magnolia, AR. We found that cosmic muon flux is uniform, appears to be independent of conditions on earth, and is anti-correlative with temperature. We are convinced that the sun has minimal to zero effect on cosmic-ray flux; it cannot be a major contributing source of this background radiation. The source of cosmic radiation remains one of the biggest unanswered questions in physics today
