In the 1930s, psychologist Winthrop N. Kellogg<\/a><\/strong> conducted a controversial experiment, adopting a 2-month-old female chimpanzee named Gua<\/strong> and raising her at home exactly like his own son Donald<\/strong>, then under a year old.<\/p>\n\n\n\n

His goal was observing if the primate could adopt human behaviors<\/strong> like walking upright or communicating, but results differed from expectations.<\/p>\n\n\n\n

Raising Gua and Donald<\/h2>\n\n\n\n

Kellogg, a Columbia University professor specializing in conditioning, learning, and human behavior, aimed to investigate animal-human differences<\/strong> in learning\/behavior.<\/p>\n\n\n\n

Study covered memory, drawing ability, vocalization\/language, manual dexterity, locomotion, problem-solving, fear responses, obedience, etc.<\/p>\n\n\n\n

Gua<\/strong> lived with Donald for nine months<\/strong>, remarkably “humanizing<\/strong>“\u2014learning faster\/more effectively than the psychologist’s son. Gua obeyed commands, kissed others, self-fed human-style, even groomed independently.<\/p>\n\n\n\n

Conversely, Donald<\/strong> developed chimpanzee-like behaviors<\/strong>: mouthing everything, howling\/grunting. He showed marked language development delay<\/strong> and communication<\/a> difficulties.<\/p>\n\n\n\n

After nine months, Kellogg ended it\u2014Gua returned to originating zoo<\/strong>. She couldn’t adapt, dying the next year. Donald, 19 months at study end, uttered limited words<\/strong>. Over time, he improved communication, even attending university as adult.<\/p>\n\n\n\n

Findings published 1931 in “The Ape and the Child<\/a>“<\/strong>, detailing Gua\/Donald learning activities\/games and effects.<\/p>\n\n\n\n
