The experiment included a baby who was ten months old and a baby chimpanzee. They were far from being the first nor the last people to survive scientific research.

Scientists have occasionally experimented on their own children in the past.

So Winthrop Kellogg, a psychologist, and his collaborator decided to look into what would happen if a newborn and a chimpanzee were raised in the same way starting at birth.

Before starting his most well-known experiment, Kellogg was a lecturer at Indiana University. He looked into the anxieties of rodents, birds, and other species. Having grown up around animals, the Mowgli children’s past was investigated by Kellogg.

He was curious as to why they couldn’t communicate despite spending so much time around people. In 1931 Kellogg submitted an application to the Yale Center for the Study of Great Apes.

He removed Gua, a seven-month-old chimpanzee, to grow. The scientist’s kid Donald was 10 months old when this happened. Their ages are comparable.

The Kelloggs’ son and the chimpanzee were given the identical circumstances. Gua shared several things with Donald, including his attitude, toys, and furniture. Gua immediately adapted and connected with Donald on a linguistic level.

Their parents watched after and evaluated their progress as they grew up together. Comparisons were made between reflexes, motions, dexterity, speech comprehension, fears, and alertness.

During the first 6 months of the experiment, Gua was in front of Donald. The chimpanzee gained independence by learning how to use a spoon, a glass, and to open doors on her own. She could learn roughly 50 orders and phrases.

mimicked other people’s actions and used hugs and kisses to show her devotion. According to Kellogg, this is a result of chimpanzees developing more quickly. Goa has been practicing using the restroom, though, for a longer amount of time.

She could never speak clearly and had no idea how to operate a pencil. After an additional 15 months, Kellogg discovered that nothing could change hereditary variables.

The experiment was abandoned when Donald was a year and a half old. He started acting like Gua, which worried his parents.

The two came to the conclusion that it is more likely for a person to turn into a chimpanzee than the other way around. They claimed that, up to a point, training may help an animal resemble a person.

The Yale Center for Great Ape Research received Gua back. Gua received abhorrent treatment. She was first forcibly removed from her customary house and then surprisingly brought back.

Two years following the conclusion of the trial, she died of pneumonia. Almost minimal information is provided on Donald. Some stories state that he died by suicide at the age of 42.

Following their discovery of the Kellogg study, psychologists began to critique it. To begin with, it is utterly unethical to experiment on a baby. Second, they were alarmed by the cruelty displayed against the little chimpanzee.

Some considered Kellogg’s contribution to the study of interactions between humans and primates was significant.
