Experiment Make Animals Think Like Human

On June 26, 1931, comparative psychologist Winthrop Niles Kellogg and his wife welcomed the arrival of a new resident. Not a human baby, but a chimpanzee baby. The couple plans to raise a baby chimp named Gua, along with their own baby boy, Donald.

As described in The Psychological Record, the idea is to see how the environment affects development. Can the chimp grow up and behave like a human or can he think like a human?


Since becoming a student, Kellogg has dreamed of doing such an experiment. He was influenced by the stories of wild children, or those who were raised without any human connection.

Because leaving a human child in the forest or in the wilderness alone is a bad and immoral act, Kellogg then chooses to experiment with the reverse scenario, which is to bring a baby animal into human civilization.

For nine months, 12 hours a day and seven days a week, Kelloggs and his wife conducted this experiment on Donald and Gua without knowing the meaning of fatigue.


Donald is 10 months old at the beginning of the trial, while Gua is a seven and a half month old Cimpazi taken from a local animal center. Donald and Gua grew up in the same house, in the same way. Both were fed, pampered, and taught basic languages.

In short, this couple teaches the same way that all parents teach their children. Dr Kellogg learned how the two babies evolved by regularly assigning tasks to Donald and Gua.


In the meantime, Gua excelled in some of the tests given. Gua grew physically faster than Donald. Gua also imitate human behaviors such as wearing shoes, opening doors, and eating with plates, glass and spoons.


But honestly, no training or parenting can counteract the fact that it's genetically chimpanzees. What worries Kelloggs is that Donald doesn't seem interested in defeating Gua in the verbal test.

Although Donald is better than Gua, but Donald is behind the other babies in communication. Donald was just better at training to go to the toilet than Gua who didn't do it. Eventually, Donald began mimicking the scream of hunger instinctively used by a chimpanzee.


The experiment stopped after nine months and Gua was returned to the local animal center where Kelloggs had taken it. To summarize the story, when Gua showed no signs of wanting to learn human language, Donald's brother Shirley Mae Kellogg began to mimic Gua's voice. It was this linguistic problem that caused Dr Kelloggs to end his experiment with his wife.
