Prikvačeni tweet
My Science Moment video series has entered the second “season”. But beware! Although they’re still short, they‘re now allowed to spill beyond 60 seconds. Moment 47 just released, uh, moments ago.https://www.youtube.com/user/mchangizi

If a parrot or crow were born with a (somehow sufficiently small) human brain inside it, would it have any idea it’s different than its flock? How easy would it be for experimenters to distinguish, if they somehow had the notion it wasn’t the usual bird?

Preview of Moment 48, on how we cognitively categorize shapes as 1D, 2D, etc, yet many (most?) natural things are 1D *and* 2D. See full video here... https://m.youtube.com/watch?v=ksBgvzsOFRU&list=PLHmody2xNMCuWf3h-TVRwOwH857PxJuYt&index=2&t=0s …pic.twitter.com/y987VRDRH8

One of the little know things about (many) parrots is that there is no sexual dimorphism. We have no idea whether Pistachio is male or female (unless we do a surgical or genetic test). Languages like Farsi can accommodate that well, because there’s no “he” or “she”.https://twitter.com/markchangizi/status/1223737447764369408 …

Many imagine our semantic network is a complex web with meanings determined by position within the network, and that there’s no foundation upon more primitive words. We can get at this by looking at dictionaries. And they’re not webs. They’re hierarchical. (And near optimal.)https://twitter.com/MarkChangizi/status/1223355651646205953 …

But for English one constantly vacillates between “him” and “her”. More generally, it interestingly strains one’s cognitive categories, because our brain “wants” to know “which is it?”

And! .. It also answers another question folks ask: Is our lexicon a web with no bottom, or is it hierarchical and grounds out at some primitive words that have no definition per se? Data suggest it’s hierarchical. (And optimally so.) Link for paper: https://www.changizi.com/uploads/8/3/4/4/83445868/dictionary.pdf …

Real data from actual dictionaries suggest they are very close to optimal.

That same idea can be applied to our entire corpus of word we know, and we can ask what is the optimal number of intermediate levels, so that the entire dictionary (the one in your head) is minimized.

If instead you first define four intermediate words, & THEN use these to define the wanted 16, the total size of the dictionary is considerably smaller because each of the 16 definitions is smaller, outweighing the extra space from the four intermediate words & their definition.

If you define all 16 words in one go, so to speak, the total size of the dictionary is big, because each of the 16 words has a long definition.

One thing about such systems is, there are more and less efficient ways of defining a bunch of words. The figure here shows two different ways to define 16 words based on two fundamental words that have no definition (the brain understands these primitively).
