안녕하세요, Davey 입니다. 날씨도 많이 추워지고, 코로나 19 때문에, 항상 긴장을 하면서 생활하고 있습니다. 이럴 때 일수록 건강 관리 잘하시고, 자신이 있는 자리에서 열심히 노력해야 된다라고 생각합니다.
그럼, 오늘 소개할 speech에 대해서, 말씀 드리겠습니다. Title은, How to practice effectively...for just about anything 입니다. 관련 Link는 아래와 같습니다.
일단, 첫 구문 자체가, physical activity를 마스터하기에는 연습이 필요하다는 식으로 애기를 하였고, 나중에 읽어 보니, 주로, 육체적인 기술을 마스터 하기 위한 효율적인 연습에 대해서, 애기를 하는 것이구나라고 알게 되었습니다.
내용에 대해서 간단하게 말씀드리면, 우리 뇌를 구성하는 것 중에, white matter과 grey matter을 애기하면서, 연습을 하면 할수로, 뇌에서 근육에게 전달하는 신경 신호 및 자극을 더 빠르고, 손실없이 전달을 할 수 있어서, 사람들이 주로, 하는 애기가, muscle memory라고 애기하는데, 그 이유가 이것 때문에 그렇다고 하네요.
그리고, 마지막으로는, 어느정도 skill을 연마한 상태에서는, 상상만으로 연습을 해도, 육체적으로 똑같은 시간을 연습한 사람과 비교해서, 비슷한 성과를 거두었다는 연구 결과를 애기하면서, 상상으로도 연습이 가능하다는 것을 애기 하였습니다.
어느 article에, 감옥에서 피아노 치는 법을 상상하면서 연습해서 출소해서 엄청 잘 쳤다는 사람 애기는 들어봤는데, 그 내용이 이거랑 약간 연관이 있는 거 같습니다.
그럼, 아래 본문 script 및 제가 공부하면서 찾은 단어 참조 하시어, shadowing 및 영어 공부 열심히 하세요. 아래 script는 TED 홈페이지 해당 speech의 Transcript 내용 참조하였습니다.
- How to practice effectively... for just about anything script & words
Mastering any physical skill, be it performing a pirouette, playing an instrument, or throwing a baseball, takes practice. Practice is the repetition of an action with the goal of improvement, and it helps us perform with more ease, speed, and confidence. So what does practice do in our brains to make us better at things? Our brains have two kinds of neural tissue: grey matter and white matter. The grey matter processes information in the brain, directing signals and sensory stimuli to nerve cells, while white matter is mostly made up of fatty tissue and nerve fibers. In order for our bodies to move, information needs to travel from the brain's grey matter, down the spinal cord, through a chain of nerve fibers called axons to our muscles. So how does practice or repetition affect the inner workings of our brains? The axons that exist in the white matter are wrapped with a fatty substance called myelin. And it's this myelin covering, or sheath, that seems to change with practice. Myelin is similar to insulation on electrical cables. It prevents energy loss from electrical signals that the brain uses, moving them more efficiently along neural pathways. Some recent studies in mice suggest that the repetition of a physical motion increases the layers of myelin sheath that insulates the axons.

nd the more layers, the greater the insulation around the axon chains, forming a sort of superhighway for information connecting your brain to your muscles. So while many athletes and performers attribute their successes to muscle memory, muscles themselves don't really have memory. Rather, it may be the myelination of neural pathways that gives these athletes and performers their edge with faster and more efficient neural pathways. There are many theories that attempt to quantify the number of hours, days, and even years of practice that it takes to master a skill. While we don't yet have a magic number, we do know that mastery isn't simply about the amount of hours of practice. It's also the quality and effectiveness of that practice. Effective practice is consistent, intensely focused, and targets content or weaknesses that lie at the edge of one's current abilities. So if effective practice is the key, how can we get the most out of our practice time? Try these tips. Focus on the task at hand. Minimize potential distractions by turning off the computer or TV and putting your cell phone on airplane mode. In one study, researchers observed 260 students studying. On average, those students were able to stay on task for only six minutes at a time. Laptops, smartphones, and particularly Facebook were the root of most distractions. Start out slowly or in slow-motion.

A Coordination is built with repetitions, whether correct or incorrect. If you gradually increase the speed of the quality repetitons, you have a better chance of doing them correctly. Next, frequent repetitions with allotted breaks are common practice habits of elite performers. Studies have shown that many top athletes, musicians, and dancers spend 50-60 hours per week on activities related to their craft. Many divide their time used for effective practice into multiple daily practice sessions of limited duration. And finally, practice in your brain in vivid detail. It's a bit surprising, but a number of studies suggest that once a physical motion has been established, it can be reinforced just by imagining it. In one study, 144 basketball players were divided into two groups. Group A physically practiced one-handed free throws while Group B only mentally practiced them. When they were tested at the end of the two week experiment, the intermediate and experienced players in both groups had improved by nearly the same amount. As scientists get closer to unraveling the secrets of our brains, our understanding of effective practice will only improve. In the meantime, effective practice is the best way we have of pushing our individual limits, achieving new heights, and maximizing our potential.
