Developmental Psychology: How Smart Can We Get
“How Smart Can We Get”
After watching PBS’s “How Smart Can We Get” from Nova Science Now, I realized how very complex the brain is. I used to think that a lot of people were born smart or they worked very hard to memorize all of the material on a test; I learned that there are special ways and techniques to help you memorize almost anything you want.
After studying Albert Einstein’s brain, neurologists discovered that his parietal lobe was 15% bigger than the size of an average person’s. He also had a different bump on his brain, which showed excessive movement of the fingers on one of his hands. Einstein played violin throughout his childhood and adult life. Learning a musical instrument is said to make people smarter, which was exactly Einstein’s case. He said that whenever he could not figure out a certain physics problem, he would go into his kitchen and play his violin until the solution came to him.
Memory champions each have their own way of memorizing longs lists of numbers and words. A memory champion taught David Pogue how to memorize a list of 40 words. He told him to imagine the word very vividly. For example, the first few words on the list were monkey and iron. So the champion told David to imagine a monkey dancing on his piano, but he said not to just imagine it dancing, but to imagine the sound and have as much detail as possible. He then told him to imagine the monkey holding an iron in his hand. The champion had David do this for all 40 words and he memorized almost all of the words on the list and all under ten minutes.
Cognitive neuropsychologists are redefining the concept of intelligence by explaining that those that are intelligent have more nerve cells connecting each other, which is gray matter. Math gifted children had five times more the activity in their parietal lobe than average children. Gray matter is made up of nerve cells while white matter is nerve fibers that connect the matter together. Neuropsychologist discovered that juggling helps increase gray matter, to make you smarter. The brain grows when someone juggles, so learning to juggle can increase gray brain matter, which increases nerve cells so basically makes you smarter.
George’s brain is unique because when he is calendar counting, his brain lights up unevenly, unlike someone who cannot calendar count. His brain lights up more on one side than the other, which is very uncommon. Acquired savants are people that suffer a severe brain injury or disease and come out of it with a skill that they did not have before the accident. In Derek’s case, he dove into a pool and hit his head on the bottom of the pool. When he woke up, he had the sudden urge to play the piano. When Derek sat down in front of a piano, he could play quite well, even though he could not play piano before his accident. He can only play one melody and cannot read music. Derek sees the notes as black and white boxes in his brain and these boxes tell his hands what keys to press.
When people get put under a lot of pressure to perform well, sometimes people “choke.” Stress messes with our working memory in our brain, which occurs in the prefrontal cortex, right above our eyes. What happens when we get put under a lot of pressure and stress, the emotional centers right below the prefrontal cortex overreact which prevents clear thinking. People that are said not to choke, don’t show signs of their emotional centers intervening with our working memory. Studies were done on students that were about to take a high-stakes biology exam. They gave the students the option of either writing down their feelings about the exam for ten minutes before, or to sit there for ten minutes before the exam. The students that chose to write down their feelings did better, on average, than the students who chose to sit there to themselves before the exam. It shows that expressing your feelings about what is causing stress can help eliminate stress quite a bit.
I thought this documentary was actually very helpful in learning how to memorize things and how to deal with stress better. It made me more aware of how to study and it taught me that I should write down my feelings instead of keeping them bottled up inside me, especially if I am stressed out about an exam or something else going on in my life.
