AbstractAn external focus of attention is considered superior to an internal focus for learning and performance. However, findings specific to changing the task difficulty are inconsistent. The present study used a reciprocal aiming task to determine the effects of attentional focus on motor performance using speed-accuracy paradigm. We constrained timing to examine how internal and external focus of attention influenced accuracy when task difficulty changes. The results indicated greater accuracy on the right target and greater consistency on both targets for the external focus condition, regardless of task difficulty. Our results uniquely demonstrated how instruction modified a speed-accuracy task. 相似文献

ABSTRACTRussia has a long, complicated and, at times, contradictory relationship with Islam and Muslims. Islam is classified as one of the ‘traditional’ religions, along with Christianity, Judaism and Buddhism. Throughout Russia’s history across the centuries, the efforts by the state and Muslims to define their relationship have led to contradictory outcomes. This special issue grew out of a conference that took place in 2016, seeking to explore the complicated nature of the image of Islam in Russia from a multidisciplinary perspective. A collection of six contributions explore how Islam is viewed and projected in the public and media sphere in contemporary Russia, including state attempts to ‘manage’ the development of Islam, initiatives to transform the public image of Muslims and the charitable work of a mosque at the local level. 相似文献

AbstractParkinson’s disease (PD) is the second most common neurodegenerative disorder. Early intervention/treatment relies on early diagnosis of PD. There is increasing interest in methods based on electromyography measurements of PD patients because of its noninvasiveness. Thus, this study was to investigate electromyographic (EMG) characteristics of the upper limb between PD patients and healthy control subjects using EMG, and to distinguish PD patients from healthy control subjects according to the EMG information using a support vector machine (SVM) classifier. Sixteen right-handed PD patients and 25 right-handed healthy subjects participated in experiments involving elbow flexion movement. The frequency power, duration, skewness, recurrence rate, and correlation dimension of EMG signals and success rate for the right hand and the skewness of EMG signals for the left hand were found to be significantly different between the two groups. This information was subsequently used to distinguish PD patients from healthy control subjects using the SVM classifier to obtain a mean accuracy of 87.02%. Although the results may not be immediately available to use in clinical applications, the safety, simplicity and speed of the system still merits further consideration. Enhancing performance accuracy and examining PD patients in different stages of disease are anticipated in future investigations. 相似文献

IntroductionThe tendency to eat by paying attention and respecting the body's hunger and satiety cues is called intuitive eating. This eating behavior has been linked to positive health and well-being outcomes.ObjectiveThe purpose of this study was to test a global model linking intuitive eating with self-esteem, body esteem, media influence and including fear of negative appearance evaluation in adolescents’ boys and girls.MethodIn total, 740 adolescent high school students (51.5% girls; M age = 14, SD = 1.5) completed self-report questionnaires with measures of intuitive eating, body esteem, self-esteem, media influence and fear of negative appearance evaluation.ResultsStructural equation modeling revealed an overall excellent fit for the final four-variable model excluding the fear of negative appearance evaluation variable. Mediation analyses showed an indirect relationship between intuitive eating and body esteem via media influence, for girls but not for boys. Body esteem mediated the relationship between intuitive eating and self-esteem, for girls and boys.ConclusionA new model is proposed where intuitive eating is associated with self-esteem through body esteem and media influence. These findings suggest that regulating attitudes and behaviors toward food may be related to higher psychological well-being. 相似文献
