The purpose of this study was to compare reaction time (RT) and fractionated RT components (premotor and motor times) between normal and postcontraction conditions. Twelve participants performed 20 trials each of control and postcontraction RT conditions. For the control condition, participants executed a learned, rapid, knee-extension contraction response to an auditory stimulus. The postcontraction condition was identical to the control condition except that the participants performed a 3-s isometric contraction of the knee extensor muscles prior to an auditory stimulus. Muscle activity was recorded from the quadriceps muscle group. Results indicated that the postcontraction condition was significantly faster than the control condition for the average RT, premotor time, and motor time. It was concluded that reaction time, processing time, and muscle contraction time for a learned task could be significantly reduced following an isometric contraction. 相似文献

Dualisms pervade the language of higher education research providing an over‐simplified roadmap to the field. However, the lazy logic of their popular appeal supports the perpetuation of erroneous and often outdated assumptions about the nature of modern higher education. This paper explores nine commonly occurring dualisms: collegiality/managerialism, student‐centred/teacher‐centred, deep learning/surface learning, academics/non‐academics; research/teaching, old universities/new universities, liberal/vocational, public universities/private universities and higher education/further education. Illustrated by reference to a range of international contexts, it is argued that over‐reliance on dualisms among higher education scholars has adverse effects including narrowing the possibilities of research design and inhibiting intellectual advancement within the field. 相似文献

College undergraduates read a 2400-word passage, responded to 16 multiple-choice questions, and received one of four types of feedback following their responses. Complexity of feedback was inversely related to both error correctability and criterion efficiency taken as a ratio of feedback study time to post-test corrects. The results were discussed in terms of depth of processing and instructional comprehension. 相似文献

Using participatory action research (PAR), this paper explores the ethical practice of students engaged in practitioner research in a higher education context. Using narrative enquiry, the paper explores the participants’ experiences of practitioner research, including ethical dilemmas that resulted from a conflict of values between the practitioner and research roles. We postulate a multi-dimensional approach to ethical practice known as ‘ethical posture’ emerging from our consideration of conceptions of inquiry that resulted in contrasting ethical behaviour. 相似文献

The present study explored the environmental and genetic etiologies of the longitudinal relations between prereading skills and reading and spelling. Twin pairs (n = 489) were assessed before kindergarten (M = 4.9 years), post‐first grade (M = 7.4 years), and post‐fourth grade (M = 10.4 years). Genetic influences on five prereading skills (print knowledge, rapid naming, phonological awareness, vocabulary, and verbal memory) were primarily responsible for relations with word reading and spelling. However, relations with post‐fourth‐grade reading comprehension were due to both genetic and shared environmental influences. Genetic and shared environmental influences that were common among the prereading variables covaried with reading and spelling, as did genetic influences unique to verbal memory (only post‐fourth‐grade comprehension), print knowledge, and rapid naming. 相似文献

For individuals with strong work identities, the decision to retire can be particularly challenging. For academic physicians, retirement is an important personal decision that also has far-reaching implications for the healthcare system. This is because academic physicians are responsible for producing the research from which key medical decisions are made, for training future healthcare providers, and for providing specialized care for patients. For this study, we conducted focus groups with academic physicians from a large research university in Canada and then performed inductive thematic analyses to examine perceptions and concerns about later life career transitions. This study highlights tensions between professional experiences for the next generation of physicians and individual struggles with personal identity. Findings suggest improvements to institutional programs that support flexible, agentive, and respectful retirement transitions will not only be beneficial but necessary as medical and university systems continue to grapple with issues of balanced recruitment and succession. 相似文献
