> We all played with building blocks, no? Frank Lloyd Wright credited Froebel Gifts, a type of building block, as being instrumental in his early development We've all played with building blocks, but few of us are Frank Lloyd Wright. Of course, the difference here is that he played with them for several years whereas I'm told I played with them but can form no crisp memories of such an event. (I don't have many crisp memories from that age and I'm cautious of vague memories without additional witnesses just being made-up.) I don't imagine I would have enjoyed being forced to play with them up through 6th grade, nor have been more Frankish, so I'm finding it hard to believe him that it was the blocks themselves that made Frank different. (Though after a little reflection, I do remember extensions to building blocks through maybe 6th grade, such as the rubber band pegs, various polygon plastic 'biscuits'[1], plastic-log-cabin-building cylinders, and connectible cubes. As well as 2D jigsaw puzzles at home and we had a couple neat 3D puzzles in 6th grade. I never liked Lego but I like Minecraft.) Thanks for the study, though. You should emphasize the last sentence like the PDF does, the "2-sigma" effect is one of the reasons why I and many others think one-to-one tutoring is the best we can do and ways to cheat that are definitely worth pursuing.

[1]Actually, apparently these things are the 2D "building blocks" referenced in the study whereas Frank seems to be talking about the 3D "building blocks" that are actually big and blocky.
