Do you ever contemplate the idea that one miniscule event in your life could have changed you forever? Imagine that you’d been just 30 seconds earlier to class that day and sat in a different seat; you could have missed out on sitting next to the person who may one day be your best friend. Perhaps you missed a song on the radio, and you may not have ever heard of what is now your favorite band. The opportunities that we take, as well as those we skip over, have the chance to mold and shape who we are and where our lives take us. Some facets could be due to pure chance, or our background may affect some aspects of who we become. Continuing with the idea discussed in class as to whether or not worms can impact intelligence, I decided to look into what else can have an effect on a person’s academic success.
There are a few obvious factors that play into a person’s measured intelligence, such as their upbringing, environment, and role models. It’s very easy to see how these could have a huge influence on an individual’s academic success. A healthy upbringing in a happy and well-off home will allow a child to focus more on their studies, and positive role models give children something to aspire towards which usually gives them a more powerful drive to do well in school. According to The Discovery Channel, there are five main factors that influence a person’s intelligence. The first is genetics, which they refer to as “nurture.” Studies show that genetics can influence anywhere from 40% to 80% of a person’s intelligence. It is also connected to the brain structure, as brain pathways with “better” development allow for better IQ scores. The next reason they list is early nutrition. They state that the nutrients received from a mother’s diet before a child is born, as well as the nutrients they receive within the first few years of life, can enhance brain structure, as well as enlarge the caudate. The caudate is a region in the brain that involves the way we learn as well as our memory. As previously mentioned, they also list “nurture” as a factor, which is essentially the environment in which a child grows up. Another factor listed is what is referred to as “birth order,” meaning that there was once an understanding that the oldest child would be more intelligent than any child born after. While this is neither proven nor disproven, it is often accepted to be true. The final factor they list is environment, which they essentially describe to be the same thing as “nurture.” They did not form a clear line between “nurture” and the “environment” or how they may each have a different impact on a child (“Curiosity”).
The question that now remains is: what other factors play into a person’s intelligence? Also, what steps could parents take before a child is born to improve their IQ? Nutrition was mentioned, but what specific nutrients benefit the brain and its development in particular?
And, as for experimenting to test these theories, wouldn’t be unethical to purposefully deprive an unborn baby or a toddler of the proper nutrients it needs? How did they create a control group?These are just a few of the many questions left unanswered by The Discovery Channel’s research.
The fact that something like genetics or prenatal nutrition, both of which are so far out of our control, could influence our intelligence and consequently our whole life is a scary concept. Life truly is a game of chance and coincidence.
