Can you workout your brain to make yourself smarter? Can you flex your brain and make your memory grow like Arnold Schwarzenegger’s hulking biceps? These questions were indirectly answered in the book, Smarter by Dan Hurley. Intelligence is made up of two distinct components, fluid and crystallized intelligence. Fluid intelligence is your ability to reason, make decisions, and think abstractly. Crystallized intelligence is your factual knowledge and practiced abilities which are learned throughout life-1+1=2, George Washington is the first president, and your reading speed. Think street smarts for fluid and book smarts for crystallized. Another definition, working memory, is your ability to manipulate things you are trying to remember. If I asked you to add 25+27 you would most likely add 25+25=50 first and then add the remaining 2 to get 52-that requires working memory. Alright, the painful part is over and we can mull over the main concepts of Smarter. Cognitive psychologists, are currently having orgasms over the new idea that we can increase our intelligence through simple brain training games. These games incorporate some sort of working memory task and are recommended to be done 30-60 minutes a day on a regular basis-think Lumosity. Overall, studies showing a positive effect for these types of games on cognitive function number 75, while there are only 4 studies that show no effect at all. This may seem like a lopsided and resounding, “Duh this stuff works, let me get my credit card and start playing falling numbers on my Lumosity profile-SmartestManAlive2014,”…but lets take a step back. These studies show improvements on the specific games played, but the real question is whether that translates into an improved fluid intelligence and consequently an improved brain that makes life easier? In my opinion, the verdict is still technically out in the scientific community but the common-sense benefits are real and translatable to everyday life. I like to use the analogy of squatting in the gym. Squats use primarily your legs but that single movement improves your concentration, discipline, balance, and overall strength. Lumosity may make you better at specific games but that brain training can translate to improved memory in everyday tasks, concentration, and quickness in decision making.
Alright, Lumosity helps, but are there any other ways to make my brain glisten with sweat? Sure there are you frick, studies show that exercise (both aerobic and weight lifting), learning an instrument, mindfulness meditation, caffeine/coffee consumption, nicotine, and low electrical brain stimulation all have positive effects on improving markers of brain function. Nicotine, I learned, is not harmful or addictive on its own, and the brain actually has nicotinic receptors. Nicotine is only addictive in combination with chemicals found in cigarettes and is currently being researched as a drug to help those with Parkinson’s Disease (the nicotinic receptor positively effects malfunctioned dopamine receptors in Parkinson’s). The effects of brain training are most profoundly seen in those with cognitive disorders, such as, ADD, ADHD, age related cognitive decline, autism, and Down Syndrome. In healthy adults, the degree of benefit is less pronounced but still apparent and helpful in creating cognitive reserve which is shown to delay age-related cognitive decline. Most of us design our life around things we are good at so we can be comfortable and happy at all times. If we try to be comfortable in everything we do, we are going to have a weenie brain and a weenie body. Do something that challenges your brain and your body and don’t squander the gifts that God gave you. IQ is only a number, what you do with that number is what matters most. If my IQ is 150 and all I do is go home, watch TV, and check Facebook each night then my intelligence is essentially worthless. Go out use your blessings, get smarter, learn an instrument, critically think, pick up a heavy weight, run really quick, and read a book. Don’t waist that beautiful brain of yours-make it glisten like one of Arnold’s biceps.
Words that I did not know:
Incredulity: a feeling that you do not or cannot believe or accept that something is true or real
Erudite:having or showing knowledge that is gained by studying
Abhorrent: not agreeable
Summed up learning sentence:
Training your brain can only improve memory/fluid intelligence if your willing to challenge yourself and the best way to train is with an activity that your most likely to stick with over the long term.
