General Mental Ability (GMA)
A little more in-depth than Intellectual Ability. In theory, it has seven dimensions (kinda like the Deadly Sins):
1) Number aptitude: Doing math in your head…more than just 2+2;
2) Verbal comprehension: Reading or hearing something and actually getting it;
3) Perceptual speed: How quickly you get it;
4) Inductive reasoning: Problem-solving, or predicting outcomes;
5) Deductive reasoning: Figuring out who’s right, or if anyone’s actually right…or at least who’s got the best idea;
6) Spatial visualization: Arranging physical things, or at least imagining what a space would look like if set up in a certain way;
7) Memory: Remembering stuff. People with photographic memories are really good in this area. Think: Sheldon. Same neighborhood.
