More great news for those with spatial delays. Gee thanks Bostonian. Grin.
Kinda depends on the nature of the testing and spatial delays. If it is mainly a physical spatial issue, then early IQ test type manipulative test are going to be inaccurate measures (e.g. WISC block design.) I can personally guarantee that internal spatial reasoning and external spatial abilities are not inherently linked.
As to the reporting, I'm thinking that reasoning backwards from this HG+ cohort for implications to SAT content doesn't make sense. I also am not sure the research inference that associates certain tangible outcomes (e.g. patents) are translatable as creativity.
