What is learning? How is this defined from the behavioral perspective?

Answer 1

Learning is gaining new information. It can be unexpected or expected, passive or/and interactive. It is a way of life, you learn as long as you live. It's how you use what you have learned that is most important and sometimes vital to good living.

Answer 2

Because they thing "nothing" of themselves - plain and simple! If they did, they wouldn't have time to obssess about what other people think!
