Learning is a relatively lasting change in behavior resulting from observation and experience. It is the acquisition of information, knowledge, and problem-solving skills. When you think of learning, it's easy to focus on formal education that takes place during childhood and early adulthood.
Learning, like reflexes and instincts, allows an organism to adapt to its environment. But unlike instincts and reflexes, learned behaviors involve change and experience: learning is a relatively permanent change in behavior or knowledge that results from experience.
