This semester psychology has been an interesting class. The only reason I took it was because it was required for me to take it, but I am glad I did. I learned so much about how people's minds work and my questions from the beginning of the semester were answered. The things that most stood out to be from this semester is about how certain things can affect people's brains. For instance the uses of drugs alters people's brains which changes the way they feel and act. Alcohol is a depressant and slows down people's reaction time and inhibits their ability to think and behave rationally. Some other drugs such as LSD are stimulants and can cause people to hallucinate. These are two widely known examples, but another think that affects how people think and behave is their environment. I find this interesting because a person can be shaped by their environment, as well as their genes. Another thing we touched on is sometimes when a part of a person's brain gets injured they can sometimes not operate as well. For example I thought the person who had a pole go through their brain and losing their personality is interesting, though it may be pretty scary at the same time. Overall I have enjoyed my semester of psychology and it was a great class to be in.
