and what it does is that it enables one particular aspect of intelligence, spatial reasoning, to function at a higher level. It does so by a significant amount, too! Eight or nine points on an IQ test, which is way more than other methods of increasing intelligence have been able to do.
Spatial intelligence, as you probably already know, is the ability to visualize things in 3D and be able to rotate that 3D object in your mind to "see" it from another angle It also covers the ability to visualize a description of a room, for example, as you read a novel.
The big thing that it does as far as I was initially concerned was that it enhances the ability to follow geographic directions. When you're in NJ, that's an essential.
Another activity that spatial intelligence is important to is flying a drone. I remember when my brother first got his drone he talked about the difficulty he had adjusting his mind to how to get it to go in a certain direction.
Yet another instance is a friend who analyze racetracks and horses so he could place more winning bets on horses. It amazed me how he could break down a track spatially and calculate how a certain kind of horse would traverse that part of the track. He did this back in the days before computers, so you had to know he loved doing math. He was so good at it that he made millions. He couldn't even get a bookie.
I think it is just a temporary effect, though. If you read the book, however, there is chapter after chapter of research studies. Many researchers have studied this.
There is even a "Mozart Effect" Symphony Orchestra! They curate their CDs to various aspects of what you might want to work with, like creativity. I think there might be some for children, too. They have a web site.
I listen to it as part of my overall attempt to keep my brain flexible. I have been listening to music for an hour each morning for quite some time, ever since I read some of the studies on how listening to music has a remarkable effect on patients with dementia. I don't have dementia, not even close, but hey, why wait? There are 30 years worth of studies in this area that show an effect, so it's kind of like taking aspirin. Effective and safe.
When I listen I don't do anything else. I don't think of anything else. Just lean back and listen and focus totally on the music.
Check your CDs to see if you have "12 Variations on 'Ah vous dirai-je, Maman', K.265." You will be dazzled. He goes from on variation to the next. It's like a listening roller coaster ride!
After I finish The Mozart Effect, I'm going to read a biography of Mozart.
