Our body language tells the world a lot about us. But can it change the way we see ourselves? The answer is YES.
Two scientists, Amy Cuddy and Danna Carney, who know much about body language, did a famous research. According to the result of their research, body language can change the chemistry of our brains. Some high-power body language can make you become confident(自信的). For example, you will feel confident when you hold your head high you will feel confident when you walk with your shoulders back; you will feel confident too when you put your arms out wide as if you were winning a race. However, some low-power body language can make you feel unconfident, such as sitting with your arms close to the body, sitting with your legs together or walking with your head down.
Why do all these happen? The scientists think the reason is that body language changes the amount(数量) of something special in our brains. It's called hormone(荷尔蒙). One kind of hormone can increase your confidence; another kind can increase your stress(压力). But too much stress hormone is bad for learning. It also increases the risk of health problems.
The result of the research is also helpful for your studies. Please remember: try to use more high-power body language in your studies then you will be confident. That is, always believe you can study well, act as if you were doing well then you will make greater progress in real life.
