A totally different style of game which also seriously stretches spatial reasoning: https://vladimirslepnev.itch.io/zigzag Inspired by Super Hexagon (remember that?), you need to repeatedly tell a "snake" which way to go with the left and right arrow keys... while the game viewport twists and rotates randomly as it continually zooms out. GoOd lUcK. (It's from here, 1 month ago: https://news.ycombinator.com/item?id=29…

Another good one is the eyeballing game, by Matthias Wandel. You have to eyeball half-distances, half-angles, center of a shape, etc.

The nod to culture war bs is pretty funny, but this is also a deep and interesting problem. In this talk Hinton relates it to conv nets (and their shortcomings). The shoe example is also great. https://www.youtube.com/watch?v=x5Vxk9twXlE

I don't follow. Wrong post?

Using less strength in your solving algo is a peak shape rotator skill. It’s yet another kobyashi Maru incident.

IIRC Kobyashi maru incident involves a no-win situation where you change the rules of the game to create a winning situation. How are we looking at a Kobyashi maru incident here? Can you explain?

Shape rotation is often used as a proxy for G.

The shapes generally progress in difficulty until they are deemed “impossible” for any human shape rotator to figure out.

If you reduce the problem to counting instead of shape rotation (3D matrix multiplication) many humans can “shape rotate” to impossibly high levels of IQ

Wowch, I'm really bad :) 9.29: https://i.imgur.com/BEEqbKL.png

Thanks for the pointer!

Difficult to control for the effects of "building toys" such as Lego being primarily marketed at boys. These types of toys help train this kind of spacial awareness from an early age. See also early computers being marketed almost exclusively at men and boys, potentially being the cause of a major drop off of women in computer sciences in the 1980s: https://www.npr.org/sections/money/2014/10/21/357629765/when...

Not really. Babies show sex differences in spatial skills. https://www.sciencedaily.com/releases/2008/12/081209100948.h...

…and once they grow up?

Sometimes the initial rotation hides a part of the shape. Also, I have always wondered if there's a way to translate these shapes to strings for quick "mental algorithm" matching. Something like, "5, left turn, 3, right turn..." I guess you'd need a normal form. The first turn can be defined as always "right" or "left," and subsequent turns can be right, left, up or down. The first turn that's "up" or "down," can be…

A small improvement: use a vowel to encode turns, and consonants to encode segment lengths. So each shape would be encoded by a "word", e.g. "bakitux". Brains have dedicated "word-processing units" and those are much faster than number-processing units.

Abstracting into words will lead to invention of words that are disconnected from the underlying geometry (i.e., shapes that are not possible due to collisions), but have strong verbal associations. Eventually, the word thinkers will redefine the system to allows them to play word games without dealing with the pesky geometric limitations.
