Chapter 3 dives into biological psychology, which refers to the study of the relationship between the nervous system and behavior. The section I found most intriguing in this chapter is the "Which Side of Our Brain Do We Use for What?" section. There is a psychomythology piece in this section about "right-brain" vs. "left-brain" people and if these types of people exist. To my surprise, there has been no research done to prove its validity. According to research, we use both sides of our brain in a complimentary way. I believe that is true, however, I'm surprised to read that there is no valid research on whether we can be classified as left-brain or right-brain individuals or logical and analytical or creative and emotional. I say this because I have never personally met anyone that has a lot of characteristics in both. Most people I've encountered either are good at math and science or writing, language, and art. However, I haven't done any particular research on the subject to probe further into people's lives. I am better at writing, language, and art and from my experience have been worse at math and science. I also don't like math and science though, so I spend the least amount of time doing it as possible. Could it be that we're better at what we enjoy doing and we haven't discovered that we're good at other things because we haven't put the time and effort into it?
