I was interested to read this recent article on PsyPost by Eric Dolan (link here). At first blush this article might appear to be at odds with a differentiation between logical-mathematical intelligence and spatial intelligence. But in fact, it is quite consistent. Mathematics is a subject, an area, a discipline; logical-mathematical and spatial are intelligences. As I’ve often pointed out, one can use various intelligences in order to achieve mastery in a topic or subject matter. Indeed, the good teacher (and the good student ) are able to mobilize their stronger intelligences in order to master material that is important. So three cheers for researcher Torkel Klingberg’s demonstration—helpful for all educators on all topics.
