A wave of recent research has pointed to the risks of over praising a child. And it seems that how to draw a line between too little praise and too much has become a high-pressure _  _act for parents.
Self-esteem (自尊)  serves as a kind of tool to measure how much children feel valued and accepted by     . This sensitivity to others'      develops because of humans' need for social acceptance, which is considered to be      to survival. As early as age 8, children's self-esteem tends to rise and fall in response to feedbacks about      peers see them as likable or attractive.     , it can also be beneficial for kids to feel bad about themselves occasionally, if they behave in selfish, mean or hurtful ways that might      their ability to maintain relationships or hold a job in the future.
In the past, many parents and educators believed that high self-esteem      happiness and success, and kids could gain self-esteem simply by getting      and awards from their parents, teachers and people around. But recently researchers have found self-esteem doesn't  _   these desired results. Instead, if parents praise their kids     , their self-esteem becomes focused on being very smart and being the best and being perfect. Building too much self-esteem of the children can not go as planned, making them feel      later on when they hit setbacks (挫折).

Children who have a      understanding of how they are seen by others tend to get recovered more readily      disappointment, depression or the like. The best path is a      road, helping children develop a positive but      view of themselves in relation to others by praising them for the      they invest and behaviors they are able to sustain, like "It's      that you're working so hard on your homework.
