I am intrigued by this study and find it validating. As a psychologist, and as a parent of two gifted kids, I have always recognized how strongly spatial skills correspond with a certain type of intelligence. These skills need to be identified earlier and nurtured. They not only correspond with STEM fields, but also with music, art, strategic planning, conceptual abilities, etc.
Rudimentary verbal and math aptitude tests just don't pick up on this. Spatially gifted kids are overlooked and these skills are rarely challenged. Some parents may notice them and encourage their children to become involved in robotics, chess, art, etc. But schools need to pick up the pace and offer more opportunities.
