Incredible experiments accidentally turn babies into 'chimpanzees'

Historically, there have been many cases of children unknowingly being nurtured by wild animals and behaving in the same way that they are nearly impossible to integrate with human society.

So in the 1930s, American comparative psychologist WN Kellogg did an experiment to raise a small chimp with his own son to prove the theory that chimpanzees could not speak and have actions. bad behavior is because they are not rivers and raised in human society like children.

The experiment to test the chimpanzee hypothesis is impossible and there is no good behavior because they are not raised as children.

Initially, Kellogg selected families whose children volunteered to participate in the experiment and asked them to strictly control their behaviors and behaviors so that there would be no discrimination in nurturing and teaching. coax the chimpanzees and their offspring.

But in fact this has failed because those volunteer parents have always had difficulty discriminating and always prioritizing their biological children.

Understanding these difficulties and it is difficult for volunteers to perform as required for their experiments, this psychologist decides to take part in his own experiments.

Gua, the 7-month chimpanzee adopted by the Kellogg family.

When his son Donald was 7 months old, the psychologist couple decided to pick a chimp named Gua of the same age to officially begin working on the experiment. .

Since then, the small chimp has more love and care from adoptive parents who are human and Donald has a younger sister.

The chimp is nurtured with Donald's son as if they were brothers and sisters.

Kelloggs strictly followed the comparative comparison of physiological data of Gua's weight, blood pressure and height, Donald from the early days of adopting Gua and considered this small chimp like his own.

Kellogg's original plan for this experiment will be done in five years, but in fact it was forced to mark in the ninth month because the small chimpanzee does indeed have more good and human-like behaviors and expressions. but Mr. Donald's biological son is the exact opposite, the boy is like a chimp in a human body.

Gua not only obediently obeyed but every time he did something that was not allowed, he would ask his "parents" to forgive him with kisses and hugs, even Gua would take the initiative to signal before they wanted go to the toilet.

Gua has learned to hold a spoon with his hand and understand a little bit of human language.However, this animal does not have as much progress as expected of the experiment.

As for the Donald chalk, the boy is always perceived slower than Gua and acts similar to chimpanzees, the boy perfectly reproduces the chirping sound of chimpanzees when he wants food and gasps. roaring violently when he saw his favorite food.

In Donald's eyes, the boy always considers Gua to be a leader, though he has been taught but most of the time he uses 4 legs to move like chimpanzees, but he learns very well. Many of Gua's bad habits like biting people, using their mouths to pick up things.

In the 9 months of the experiment, Donald could only learn 3 single words, while a normal child of the same age was able to speak about 50 words fluently and started saying simple sentences.

Gua not only obediently heard but used kisses and hugs to express affection.

That's why Kellogg had to cancel this experiment because Gua could not speak and behave completely like a human, but Donald, his biological son, turned into a chimp in the form of a child.

After the experiment, Gua was sent back to the chimp populations in Orangery, Florida and continued to be fed by its own parents.

However, as Kellogg has surmised, Gua could not eliminate the habits formed during the experiment and could not stand life in iron cages.

Gua's mentality is completely unstable because he does not know how to behave like other chimpanzees or behaves like a child when he was raised at Kellogg's house and died of illness when he turned 3.

During the 9 months of the experiment, Donald always studied chimp's behavior and Gua's bad habits.

After parting with Gua, Donald has a completely different transformation, the boy has changed bad habits like chimpanzees, cognitive ability and language have also been developed quickly and catch up with the children. other in the same age.

Even Donald was smarter than normal children and became a psychiatrist after graduating from Harvard Medical School.

Although there were no serious consequences, for decades afterwards, Kellogg himself was heavily criticized by the society for the experiment.
