I agree with the article that spacial ability is an untapped resource, key to understanding and problem solving. I think there is a pretty easy way of testing this, simply by finding out what they find funny. Different kinds of humor tap this skill, and those drawn to certain types of humor, IMHO, likely have better spacial skills.
