The Most DISTURBING Human Experiment

What happens when a child is forced to accept another as a sibling? Well, what happens when the new baby sister is actually a chimpanzee? A couple conducted an experiment in the 30s, using their own toddler as the control and a baby chimp as their test subject. However instead of the chimp learning to act like a human, they got unexpected results as their own child ended up having developmental issues. Monkey see, monkey do? Let’s get into it.

I feel horrible for Gua, imagine growing up with a loving family and then out of nowhere they abandon you but you don't understand why. Gua didn't know she was just part of an experiment, this was her family. Of course Donald was also a victim, but he at least got to stay with his parents.

I wonder if they used an older child (maybe 2 years old?) and a younger monkey they might have gotten results closer to what they wanted. The problem was the baby wasn’t a full human yet and hadn’t learned enough human behaviors and the monkey was too old and had learned too many monkey behaviors

I Googled; Gua reportedly died less than a year after being returned to the primate center.

Did her mother remember her, and re-bond with her? Her short life was so full of trauma.

@äpplet 1234 Exactly, it kills me how people don´t stop to think that, life out on the wild is way way harder than in human society where you don´t have to worry about being prey, about diseases, about being out in the cold or having to fight for food, it is crucial for an animal to learn how to adapt to the environment at a young age. (i know that this isn´t the case for all humans, there are people that still have to worry about all of that, but i´m referring to people like the ones conducting the experiment).

Have you heard of the language experiment done on a young male orangutan? He was able to get simple words like Koko, and was very social with the researchers and grad students at the university where he lived. The grad students would take him out for icecream as a treat sometimes and people usually thought it was cute until he started getting bigger and accidentally hurt someone. Because of this incident they had to stop their studies and he was sent to a nearby zoo. The saddest part is that the researchers would go to the zoo to check in on him and see how he was doing, but he wasn’t able to socialize with the other orangutans, and would communicate things akin to “why am I in here with these animals, take me home” (that’s a translation by his researchers, no apes have been able to string together full sentences, even after being taught words)

@agalaxy8397 Год назад

I personally believe this one theory: when humans are born, our brains aren't very developed. Meanwhile when animals are born, their brains are far more developed. As time goes on, their brains will finish developing. Part of why "nature" might be so strong is not only a shorter timespan to "mold" the brain a certain way, there's less of the undeveloped brain to mold. Human babies are so impressionable because it's so easy to imprint them- and unimprint them. It's also why humans need like 20 years to mature while other animals are adults in like 6 months. There's less to learn for them to survive.

Unethical scientific research seeks to answer the most interesting questions. Unfortunately, it's deeply harmful to the subjects. For example, it would be cool to know the limits of the human genome (how large or small can a human be and still be healthy), but obviously we can't force a group of humans to selectively reproduce like that on any time scales in an ethical manner.

Interresting how the difference between monkey and human is humans innate ability to learn through mimicking. The monkey seems to have a more instinctive learning curve and because a human child learns through mimicking, the monkey would be the dominant influence. I loved that part, nice video.

@joejanota707 Год назад

The changes make perfect sense. The boy, having a more complex brain, would be capable of imitating and learning effective behavior from his peer. His peer, could not. Observation is used as a crucial learning method. I wonder if the boy had any interaction with other human children. Doing so should have advanced his development without compromising the experiment. Though it is hard to understand what outcome anyone could hope for, besides the one they got. You only have to look at the slight differences in neurodivergent humans and the changes in social behavior and communication. To understand why a different species might struggle to behave as a human. Being neurodivergent myself, I'm well aware of how small differences in very specific parts of the brain can make one person look completely different to their typical counterpart.

This would only be fair if you used a deaf human that only used sign language with deaf parents, as a chimpanzee can't speak. It would also be better if you used an orangutan or a bonobo, or maybe a gorilla. Not a chimp. Having an orangutan, bonobo, or gorilla (preferably female) raised by deaf parents who use sign language would be best.
