[originaltext] Hi. Welcome. Today I’m going to talk about how children learn

Hi. Welcome. Today I’m going to talk about how children learn social behaviors, especially how they learn lessons from the family, which is the most basic unit of our social structure.
    There’s a lot of discussion these days about how families are changing and whether non-traditional families have a good or bad effect on children. But it’s important to remember that the type of family a child comes from is not nearly as important as the kind of love and support that exist in the home.
    There are three ways by which children acquire their behavior: through rewards, punishments, and finally, modeling. In today’s lecture, let’s first discuss rewards. A reward can be defined as a positive reinforcement for good behavior. An example of a reward is when a parent says: "If you eat your vegetable, you can have ice cream for dessert. " Or a parent might say: "Finish your homework first. Then you can watch TV. " Most parents use rewards unconsciously, because they want their children to behave well. For example, a parent might give a gift to a child because the child behaved well. Or parents might give a child money for doing what the parents asked.
