The homework this week was definitely a step up from last weeks work and gave everyone a good idea of the amount of work that is required of this class, I believe. At the beginning of the week, I was excited to get down to business with the reading and start to learn about the physical brain. I have always had a very strong interest in the brain's processes, so the reading was not bad to me most of the time. Modules 14/15, however, were a little rough. It was difficult to wrap my mind around how heritability works. I found it very amazing, though, how twins who are separated at birth and go decades without knowing each other turn out to be extremely similar. I always knew that genetics obviously play a huge role in who we are and that identical twins have the same genes so they must be incredibly similar, but I assumed that the environment we are raised in has nearly as much effect. I thought this because when you spend a lot of time with another person, you tend to pick up certain things that they do such as sayings and other mannerisms. I figured if it is that easy to become like the people we are surrounded by, then a great amount of our personality could be contributed to our surroundings. This is why I was kind of shocked when I read about how little our parents/siblings have to do with who we become. Most kids are surrounded by their family more than anyone when they grow up, so it only seems logical to believe that they would develop similar traits to their family members. Reading about this made me more interested in the whole nature vs. nurture debate. I realize now why it is such a big topic in the psychology field.
