Spatial Ability, Creativity, and Innovation

In response to Are We Ignoring Spatially Talented Creatives, and Losing Innovations along the Way? I wrote the following:
The types of tests have changed, and maybe narrowed a bit, but when I was 12 years old and in middle school, junior high to some, we took the Differential Aptitude Tests battery. It included, among other things that are standard nowadays, tests for abstract reasoning (non-verbal, non-numeric), mechanical reasoning, and space relations, and these three (3) tests were deemed predictors of "mechanical, technical, and skilled industrial work." Maybe decomposing the standardized tests into batteries might better predict preparedness for modern work, inclusive of, but expanding on, the 3 R's of reading, writing 'rithmetic, and in particular, people that are good at "bending metal."
