The Cognitive Tradeoff Hypothesis S3 (Ep 1)

Humans are the only Earthlings with complex language. But at what cost was that ability acquired? In this episode, I visit Tetsuro Matsuzawa to learn about his influential cognitive tradeoff hypothesis.

  • One way to test this tradeoff hypothesis would be to implement the memory test on chimpanzees that have been taught sign language. If the hypothesis holds true then the chimpanzees who know sign language should have worse memory test results than the regular chimpanzees.

  • I wonder if mentally translating the numbers into, "one", "two" etc slows the process down. The chimps just see symbols. I also wonder if improving at this would be much like sight reading music where eventually you go into "sponge mode" and don't translate to say an E flat but just know what it is without paying that much attention. Great documentary. :)

  • The question here would be, if we train a human being for as long as that chimpanzee, which one would perform better? That’s not a brilliant hypothesis . It would have taken a long long time for those chimpanzees to find a correlation between the order of the numbers, and how would a new chimpanzee act???!! I still think we would be better even in short-term memory. We have additional amount of prefrontal cortex that made language possible. The idea is wrong from the start, we didn’t need any tradeoff.

  • Its all about environment, look at Speed cubers (Quick solving Rubix cubers), High level rhythm gamers, Chess players, Jazz Musicians, FPS gamers, I can list so much it hurts for an example. The more you concentrate on specific traits you will be able to achieve things that seem "inhuman". Anyone ever heard of "OSU!"? Like, I have never seen this Micheal be so sucked into something before while not looking at actual human capability. Luv ya bruh, but this was weak. sorry for raging.

  • I’m sorry but those chimps are in a fairly controlled environment and trained to take those tests. Put a human in those conditions, since birth like them, with a repetitive daily task to obtain all meals and he/she will do just as well. This hypothesis is severely flawed.

  • This is obviously not an apples to apples comparison between chimps and humans at this task...also, Ai’s mistakes seem to have to do more with a lack of dexterity. I have heard that humans have greater dexterity than chimps, and she is old, so that would make sense

  • Id like to see if replacing the numbers with circles of increasing size would have any effect or perhaps different shapes so that our brains dont try to read the numbers. Id also like to see them try to teach the chimps some basic math.

    • +Skippy BestDog Scientists want to work on humans and probe and test them, in such things as desperation of food and survival. But it seems this is a humanitarian issue, the humans need to accept and not be forced into cages. In saying that, there are many tests online of human behavioral concerns under pressure. Vsauce even mentioned at 22:16 revisiting the Stanford Prison Experiment again!!

    • No. It would take thousands of years of forming the connections in the brain and even the which particular parts are more convoluted than others through evolution by natural selection. Plus evolution cannot work backwards! So our physical brain could never be at the same level of the evolved monkeys brain ever again. I agree they would be quite good through pure desperation of food. But not 0.5 second good! Plus the 'want' to do this would be missing. These monkeys have free choice in the matter. A free choice human would sit at home on the Internet :D

  • Pictures Vs logic. My brother has dyslexia. He can spell some very difficult words that he has remembered. I can ask, how do you spell: "Occupational Therapeutic Syndrome" And he'll get every letter correct. BUT if I ask him to spell a word he has never ever seen before, the most shocking thing happens. I ask, how do you spell: 'Descry' (a descriptive word meaning catch sight of). He will say: Z then A then U then any amount of jumbled letters for any length! Dyslexic people do not form words by sounding them out, or using common association like SH has the letter S then H. They look at EVERY single word as a picture! That's right, he cannot read or spell a single word. But he has memorized the squiggles (pictures of formed words) so perfectly that he knows ... I have no idea maybe 100s of thousands of words. He can read them write them down fully BUT he must learn the picture or look of the word first! When I was a child helping him spell words, and still ignorant to his condition. I could not understand how he could spell Kite but when asked to spell say CAT, he would say: S then M then X then B ??? NONE of these letters are in cat! I would have accepted K, but not X!!!! It was the most strangest thing, that after he memorized the picture of the word he'd know it forever. Plus (I suppose due to this) his memory is incredible, my Mom has confirmed that some of his memories (in detail) at say 2 years old is precisely the scene at the time! I think my earliest memory is late 3yo of a single gate! He remembers the entire house, the plants, the color, and even a broken window!!! My brother is truly amazing, sometimes I think he's a savant. But whilst growing up, many doctors have informed us he is merely dyslexic and has learned to memorize letters forming words, obviously lots of them! I bet my brother could do this memory test a lot better than Vsauce did. Edit// Spelling :) EDIT 2// This must be said. He's a logistics manager at one of the most leading international companies, a millionaire and owns (outright) 2 houses!!!!! Whereas I went to Uni, and I'm in absolute poverty and still renting. Pay day is today, that's good because I need some food, hanging out!!! Anyway that's our society, all good.

  • It's interesting how our human evolutionary path, which led us towards complex social skills such as language, art, math, science, curiousity & the desire to learn & share our discoveries, was at the cost of other skills. It makes sense of course - evolution tends to pick just one or two key paths at the sacrifice of others. But the loss of things like short term memory may be the reason why our progress hits a wall in the fields of math & science. Our strengths in some ways are also our downfalls. Maybe we can learn a thing or two from "less intelligent" animals who preform better on these tasks ;)
