Winthrop's results showed that he was disappointed that Gua had hit a wall of development. He hoped that immersing the ape into the human household would have created the reverse of a wild raised by wolves child. It's undeniable that Gua did developed many human like behaviours such as walking more upright, being relatively potty trained, understanding a multitude of commands and even showing off her problem solving skills.

Ultimately Gua was limited by the fact that she was a chimpanzee, and that her heredity limited her ultimate ability of language.

He was only in possession of around 6 words, but he did show signs of vocal imitation, although not from his human carers, but instead from his chimpanzee sister. The child would screech and scream like an ape.

Gua although not learning to speak words herself, did learn the words spoken to her and began to show signs of being able to differentiate between different commands, Her word reaction vocabulary eventually expanded to around 95 words.

Another test was devised where reward was placed behind a wire mesh attached to a door frame. The only way to get the reward is via the use of a hoe to drag it under a small gap under the mesh. Both figured out out the solution at around 100 attempts, Gua proved to be more consistent in her success rate.

The chimp's ability to learn and develop in human environment showed that apes are capable of a surprising amount of learning and adaptation. However, the experiment also revealed that inherent physical and cognitive differences between humans and apes prevent them from fully replicating human behavior.
