Typing uses a different part of the brain than writing, and you have to think less because the letters are all at your fingertips, so it's easier to do. But the people who type are at a disadvantage, because it is all mechanical and not necessarily thought. The other 28.6% of people who like to write things down will remember the notes they take better than the people who type, because the part of your brain used to write is tied to the memory part so when you write it sticks in your memory.
When you take a test, the notes you typed will not be of much use if you did not review them multiple times, whereas even if you only wrote down your notes once, you have a better chance of remembering them.
There have been studies done all over the world to study typing and spelling. In England, there was a study done to see if people from an earlier generation were better spellers than the people from this generation. It was found that women over the age of 65 were the best spellers. (Graeme) When these women were kids technology wasn't very big. Being able to type something and have misspelled words be corrected was a dream for most kids doing their English essays. If a kid who only types were to be put into a time before technology, they would be in big trouble.
Since the age of 3, kids have been trying to spell. They start with squiggles on a paper and show off their “writing”. (Kaye) But, little do these kids know that soon they won't be writing anymore. Now, most kids are taught to type in about third grade. They are being taught an easier way to express their thoughts and it isn't helping in their writing skills.
