阶级的涵义

It is common to believe that learning just takes place in school, but much of human learning happens outside the classroom, even from birth and people continue to learn throughout their lives.

Even before they enter school, young children learn to walk, to talk, and to use their hands to use toys, food, and other objects. They use all of their senses to learn about the sights, sounds, tastes, and smells in their environments. They learn how to communicate with their parents, grandparents, siblings, friends, and other people important to their world. When they enter school, children learn subjects like reading, writing, and maths. They also continue to learn a lot outside the classroom. They learn which behaviors are likely to be rewarded and which are likely to be punished. They learn social skills for communicating with other children. After they finish school, people must learn to deal with many changes that affect their lives, such as getting married, raising children, and finding and keeping a job.

Because learning continues throughout our lives and affects almost everything we do, the study of learning is important in many different fields. Teachers need to understand the best ways to educate children. Scientists, social workers and other human service workers need to understand how certain experiences change people’s behaviors.

Learning is closely related (相关的) to memory, which is the storage of information in the brain (大脑). Scientists who study memory are interested in how the brain stores knowledge, where this storage takes place, and how the brain later offers knowledge when we need it. However, scientists who study learning are more interested in behavior and how behavior changes as a result of a person’s experiences. 
