As some who has a dis-harmonic intelligence profile, this has been obvious for a very long time. In the family of my mother there are several individuals struggling with language while excelling in the field of exact sciences. I very strongly suspect that my non-verbal (performal) IQ is much higher (around 130) than my verbal IQ (around 100). I have struggled my whole life to express my ideas with language. I consider myself an abstract visual thinker. I do not think in pictures, but in abstract structures. During my life, I have met several people, especially among software engineers, who seem to be similar to me. I also feel that people who are strong verbal thinkers have the greatest resistance against idea that language is not essential for higher cognitive processes.
