Does practice make perfect?

The old saying "Practice Perfection" has been applied to various research from high school chemistry and creation to music and sports. One thing is obvious, while experts continue discussing the best time to success and the type of practice. Training improves performance and changes brains.

More than a century ago, scientists began to study the impact of practice on performance. According to a survey of women working in a cigar factory in the 1950s, people can finish their work earlier, even after years of practice (in this case a cigar). Recently sports scientists who have studied college basketball players have found that skilled players make better predictions on the free throw line than other parts of the court. However, when the player tries to jump over the free throw line, he does not see a similar effect. This means that many exercises can improve certain actions over other exercises.

With the advent of brain imaging technology it turned out that the human brain maintains the ability to change its structure and function throughout life through a process of plasticity called empirical or learning-dependent. These changes include the strength of relationships and changes in activities related to specific actions and conditions. For example, when comparing the brains of a professional violinist and an amateur violinist, scientists discovered that the pro showed higher activity in the auditory cortex and the auditory cortex processes the brain part of the sound.

These and other discoveries over the past two decades have greatly contributed to our understanding of learning and memory. In order for practice to practice brain changes dependent on learning, we found that there must be meaning, motivation, skills, challenges and rewards. My laboratory uses this knowledge to develop a principle based approach to promote the restoration of voluntary movements of people with loss of motor skills such as stroke, walking and hand grip. Ultimately, I would like to optimize neurological rehabilitation by accelerating skill acquisition program.

Carolee Winstein is a physiotherapist and rehabilitation scientist at the University of Southern California. She developed behavioral interventions on social and psychological science of neurological rehabilitation, neuroscience based on motor learning, and behavioral changes.

It may not be surprising that students will benefit from practice. Ultimately, do not practice perfection? Unexpected discovery of cognitive science means that practice is not perfect. Please practice until you are perfect, you will be perfect for a short time only. What you need for continuous exercise Through continuous practice, I mean on a regular basis, constantly reviewing or using target materials (eg reflecting recent historical data) Periodic use of new computing skills to solve increasingly complex mathematical problems This transcendent practice is one of three important educational objectives: acquiring facts and knowledge, acquiring skills, or becoming an expert It is necessary to satisfy.

Conclusion? Today's challenge to you is that a famous cellist Mr. Ma Youyou said, "I think practicing is perfect, I do not think that practice is eternal, only perfect practice is perfect" . Please challenge. These people are deeply involved in health care and health. For everyone involved in cancer in particular, I will challenge you, I will look into your exercise in detail and ask yourself, I will practice my exercises perfectly in a way to make old ways permanent Do you have?

Why do people stop improving? Practice is not always perfect. Practice makes it permanent. If you always practice in the same way you will stabilize. When many people reach an "acceptable" level of performance, we stop deliberately making improvements. Because they made little mistake, their customers rarely complain (although they may not always come back). Their managers no longer make them better. Continuous improvement beyond a certain point requires motivation, time and skill.
