. We go through a lot in our life and just in one year everything can change for us. These changes can happen because of what we have had or learned and wanted in the past. It can also help us not make the same mistake we made in the past or observe what others have done. This article focuses on the application of knowledge and applications to long-term memories, classical conditioning, positive reinforcement, and children's language learning. Long-term memories are files stored in the “files” area of ​​our brain. We use these memories to learn from them, so that we can guard against things similar to these experiences we have had in the past. With each passing day, each of us will learn something new in this life and we try not to make the same mistake as in the past. These memories contain sad or happy things that happened in our life and we forget some things because they are not important to us at the moment. It's interesting to me because one day you can be sitting down and start remembering something that happened when you were just 8 years old. It could be your first love and the most important person in your family who died or something you thought you had forgotten. This is helpful because you start by talking about the mistake you made in the past and how you should have learned from it. If you look at the mistakes you have made in the past, you will not repeat them. I would use it to solve the problem I have in my life, which is not keeping anything in my heart for people who have hurt me in the past. So when I was a freshman in high school, one of my friends made fun of me for being in ESL (English as a second language) and the truth is, I hate it to death and I just... in the middle of the paper. .....king for us and it also turns into words after we grow up a little. This is interesting because a baby can hear you when he is in the womb and can help his parents teach that baby. This is helpful to know because you're talking to that baby and teaching him everything you want him to know before he comes out. We apply what we learn every day to help us in our lives. About applying knowledge and applying long-term memories to avoid making the same mistakes we made in the past and not making them again. Classical conditioning helps force people to do something to see the reaction to doing things for something they are experiencing. Positive reinforcement to reward you for achieving a goal. A child learns a language even before being born with that word. We learn new things every day to help us in this world.
