The topic I most found interesting and memorable this semester in Psychology was when we learned about the different components of intelligence. I enjoyed both the lectures on the subject and the discussion section for the topic of that week. Intelligence can be so variant from person to person, and I thought it was important to realize the causes and examples of different types of intelligence. As the text states, there is the concept of g, or general intelligence, but there are also nine different forms of intelligence that psychologist Howard Gardner narrowed down to define the different ways a person can have intelligence. For example, there is linguistic intelligence, where a person can write and speak well, musical intelligence where an individual is musically inclined, or spatial where a person can reasonably and easily think about an area or space. Intelligence or how people are perceived based on their intelligence also varies between cultures. An "intelligent" act in one culture could be construed as something completely different in another. Because of these different types of intelligences, there has never been an IQ test developed that reasonably and fairly, without bias can test a person's intelligence. I also found it interesting this semester learning how much genetic influences have on IQ, or if intelligence is more largely based on the environment a person was raised. Twin studies were an interesting example when learning further on this subject as it showed there was a high correlation of the level of intelligence twins shared, especially if they are monozygotic. This shows that genetic influences do play a large part on the IQ of a human being.
Agreed. I found the whole concept of IQ fascinating. I think it's a bit of a stretch, at least by today's understanding of the brain to think that we can boil down the entirety of a brain's functioning power into one number. Psychologists are definitely on to something though, because there are some pretty strong correlations that arise from IQ.
