Thanks, good to see there are some tools for long term memory testing.

I think of those more as baseline skills (with some aptitiude component) that many people never grok accidentally through school. Along the lines of my going through school getting marked down for handwriting, and not realizing until my thirties that I've been holding my pencil wrong my whole life and no teacher ever mentioned it. Or when I was in school they didn't teach study skills or note taking.

To the origional post if a kid is particularly talented in memory encoding and retrieval, then they could show a marked discrepancy between achievement, IQ, and effort.
