Say for instance you are feeding your child dinner: They are spitting the food out saying they don’t like it even if they loved the exact same food just a few days earlier. What to do? There are discipline actions such as “no dessert until you finish!” or positive reinforcement, “If you eat this then I can give you a dessert when your plate is all gone!” It is all about what you say is what you get. Child behavior development a key to cognitive development and can partly determine the aggressiveness of the child. If you constantly fight with them, they will either fight back (because of being around the environment) or they will become an introvert feeling like they might disappoint their parents because they feel like they are always in trouble. This can also determine how the child reacts to the disciplinary actions or the positive reinforcement. The child’s mind is extremely absorbent in the early childhood stage and it is important to focus on the good things! If a child makes a mess in the living room trying to build a castle for you with building blocks, you should try to focus on the fact that they meant well and calmly explain to them why it is important to put their belongings away and then give them praise when they play with toys again and clean up by themselves! Positive reinforcement results in changes of brain chemistry or how a child thinks. This has been proven in Pavlov’s experiment with the salivating dogs. The behavior changes with positive reinforcement. The dog produced excess saliva when he heard the bell meaning there would be food rewarded. A child will act the same way to receive praise from the parents. good behavior then would make more praise. If you were to slip (we are all human) and yell, they would understand that they should not do that anymore because as a child they would not want to be confronted with anger.
