    The fourth dimension: A motoric perspective on the anxiety–performance relationship

    Get PDF
    This article focuses on raising concern that anxiety–performance relationship theory has insufficiently catered for motoric issues during, primarily, closed and self-paced skill execution (e.g., long jump and javelin throw). Following a review of current theory, we address the under-consideration of motoric issues by extending the three-dimensional model put forward by Cheng, Hardy, and Markland (2009) (‘Toward a three-dimensional conceptualization of performance anxiety: Rationale and initial measurement development, Psychology of Sport and Exercise, 10, 271–278). This fourth dimension, termed skill establishment, comprises the level and consistency of movement automaticity together with a performer's confidence in this specific process, as providing a degree of robustness against negative anxiety effects. To exemplify this motoric influence, we then offer insight regarding current theories’ misrepresentation that a self-focus of attention toward an already well-learned skill always leads to a negative performance effect. In doing so, we draw upon applied literature to distinguish between positive and negative self-foci and suggest that on what and how a performer directs their attention is crucial to the interaction with skill establishment and, therefore, performance. Finally, implications for skill acquisition research are provided. Accordingly, we suggest a positive potential flow from applied/translational to fundamental/theory-generating research in sport which can serve to freshen and usefully redirect investigation into this long-considered but still insufficiently understood concept

    A Theory of Humanity: Part 2—Conditions for True Universalism

    The currently used humanity model is chaotic, devoid of logic or coherence. In Part 1 of this two-part paper, we examined human traits of a scientific model in absence of ‘born sinner’ starting point. We demonstrated that the so-called ‘viceroy model’ that is characterized as scientifically sustainable can replace the existing models that are based on fear and scarcity. Part Two of the paper deals with adequate definition of moral campus that conforms to the viceroy model. In this paper, it is shown that the talk of morality or a moral compass is aphenomenal in absence of strict necessary and sufficient conditions. It also follows that natural justice can only be followed after defining the term ‘natural’ with the same scientific rigor as that of the viceroy model. Once these terms are consistently defined, one is well poised to talk about inalienable rights, moral compass, environmental sustainability, and humanity. The immediate consequence of this model is the demonstration that currently used governance models, such as democracy, is inherently implosive and must be replaced with a new model that is in conformance with the scientific definition of ‘natural’. This emerging model is free from inconsistencies and will remain effective as a governance tool that optimizes individual rights and balances with the right of the state as well as a Creator. It is concluded that this model offers the only hope of maximizing individual liberty without compromising universal peace and natural justice. At this point, morality and legality become equivalent to each. The implications of this paper are overwhelming, making all current judicial actions immoral, in essence repudiating the entire Establishment as little more than a mafia entity, bringing back ‘might is right’ mantra, packaged as ‘social progress’. The paper finally shows how a standard that is necessarily and sufficiently universal can become impetus for a true knowledge

    Prenatal screening, ethics and Down's Syndrome: a Literature review

    Get PDF
    This article reviews the literature on prenatal screening for Down's syndrome. To be evidence based, medicine and nursing have to take account of research evidence and also of how this evidence is processed through the influence of prevailing social and moral attitudes. This review of the extensive literature examines how appropriate widely-held understandings of Down's syndrome are, and asks whether or not practitioners and prospective parents have access to the full range of moral arguments and social evidence on the matter. Highly valued ideals of justice, personal autonomy, parental choice, women's control over their reproduction and of avoiding harm can all tend towards negative rather than neutral approaches to Down's syndrome. This article considers how ethics and prenatal screening policies and practice that take greater account of social evidence of disability could use moral arguments that inform rather than determine the choices of people who use prenatal services

    Development and initial validation of the Music Mood-Regulation Scale (MMRS)

    Get PDF
    This study designed a measure to assess the perceived effectiveness of music as a strategy to regulate mood among a sport and exercise population. A strategy of assessing and comparing the integrity of competing hypotheses to explain the underlying factor structure of the scale was used. A 21-item Music Mood-Regulation Scale (MMRS) was developed to assess the extent to which participants used music to alter the mood states of anger, calmness, depression, fatigue, happiness, tension, and vigor. Volunteer sport and exercise participants (N = 1,279) rated the perceived effectiveness of music to regulate each MMRS item on a 5-point Likert-type scale. Confirmatory factor analysis (CFA) was used to test the integrity of four competing models, and results lend support to a correlated 7-factor structure for the MMRS (RCFI = .94; RMSEA = .06). Cronbach alpha coefficients were in the range of 0.74 – 0.88 thus demonstrating the internal reliability of scales. It is suggested that the MMRS shows promising degrees of validity. Future research should assess the extent to which individuals can develop the ability to use music as a strategy to regulate mood in situations in which disturbed mood might be detrimental to performance

    Psychophysical and ergogenic effects of synchronous music during treadmill walking

    Get PDF
    The present study examined the impact of motivational music and oudeterous (neutral in terms of motivational qualities) music on endurance and a range of psychophysical indices during a treadmill walking task. Experimental participants (N = 30; mean age = 20.5 years, SD = 1.0 years) selected a program of either pop or rock tracks from artists identified in an earlier survey. They walked to exhaustion, starting at 75% maximal heart rate reserve, under conditions of motivational synchronous music, oudeterous synchronous music, and a no-music control. Dependent measures included time to exhaustion, ratings of perceived exertion (RPE), and in-task affect (both recorded at 2-min intervals), and exercise-induced feeling states. A one-way repeated measures ANOVA was used to analyze time to exhaustion data. Two-way repeated measures (Music Condition Trial Point) ANOVAs were used to analyze in-task measures, whereas a one-way repeated measures MANOVA was used to analyze the exerciseinduced feeling states data. Results indicated that endurance was increased in both music conditions and that motivational music had a greater ergogenic effect than did oudeterous music (p .05) upon RPE or exerciseinduced feeling states, although a moderate effect size was recorded for the latter (p 2 = .09). The present results indicate that motivational synchronous music can elicit an ergogenic effect and enhance in-task affect during an exhaustive endurance task

    A SYSTEMS APPROACH TO THE PROBLEM OF FALLS IN OLD AGE

    Get PDF
    The problem of falls in old age is enormously costly and disruptive for the older individual, others, and society, and its severity is likely to intensify as our population ages. This dissertation takes a systems-oriented approach toward the falls problem and is presented in two parts. The first part critically develops a new approach to the problem of falls. The second part describes an empirical study that applies this new approach in a pragmatic manner. Conventional fall prevention strategies employ a reductionist approach to the problem of falls. This approach is questioned because it corresponds poorly to the holistic nature of postural control. A systems-oriented conceptual framework explains postural instability in old age as the gradual decline of a postural control system’s ability to adapt. Realizing that falls arise from a complex system of interacting components of various levels and domains makes it imperative to investigate interventions aimed toward systemically fostering robust postural control. A dynamic systems theoretical framework is outlined that views postural control to be the result of synergies which function to control myriad inherent degrees of freedom. Complexity-based measures of postural sway are suggested as indicators of postural control system robustness. This new approach to the problem of falls is applied in an empirical study in which Tai Chi serves as a systems-oriented intervention. Using a dynamic systems perspective, motor imagery, along with other Tai Chi principles, are hypothesized to provide interacting physical and cognitive constraints on motor behavior that form synergies which enable robust postural stability into old age. This hypothesis was tested in a quasi-experiment comparing effects of Tai Chi motor imagery in Tai Chi experts and non-experts. The expected significant effects on postural sway complexity were not found, but significant main effects and interactions on sway variability and ease of imagery were discovered with respect to expertise and imagery type. Findings, results, innovations, implications and future directions are presented, and discussed as they pertain to four specific aims, and to ameliorating the problem of falls in old age

    Intellectual Property, Globalization, and Left-Libertarianism

    Get PDF
    Intellectual property has become the apple of discord in today’s moral and political debates. Although it has been approached from many different perspectives, a final conclusion has not been reached. In this paper I will offer a new way of thinking about intellectual property rights (IPRs), from a left-libertarian perspective. My thesis is that IPRs are not (natural) original rights, aprioric rights, as it is usually argued. They are derived rights hence any claim for intellectual property is weaker than the correlative duties attached to self-ownership and world-ownership rights, which are of crucial importance in any left-libertarian view. Moreover, IPRs lack priority in front of these two original rights and should be overridden by stronger claims of justice. Thus, as derived rights, IPRs should not benefit of strong enforcement like any original rights especially if it could be in the latters’ detriment

    Consciousness, cognition, and the hierarchy of context: extending the global neuronal workspace model

    Get PDF
    We adapt an information theory analysis of interacting cognitive biological and social modules to the problem of the global neuronal workspace, the new standard neuroscience paradigm for consciousness. Tunable punctuation emerges in a natural way, suggesting the possibility of fitting appropriate phase transition power law, and away from transition, generalized Onsager relation expressions, to observational data on conscious reaction. The development can be extended in a straightforward manner to include psychosocial stress, culture, or other cognitive modules which constitute a structured, embedding hierarchy of contextual constraints acting at a slower rate than neuronal function itself. This produces a 'biopsychosociocultural' model of individual consciousness that, while otherwise quite close to the standard treatment, meets compelling philosophical and other objections to brain-only descriptions
