Transcript of Bonobos & Chimpanzees

What exactly are bonobos? BONOBOS & CHIMPANZEES IN LANGUAGE LEARNING Pan paniscus Genus pan Common chimpanzee South of the Congo river Physical Appearance More gracile than common chimpanzee A black face with pink lips, small ears, wide nostrils and long hair Slim upper body, narrow shoulders, thin neck, long legs Great ape "KANZI" Kanzi, a male bonobo, surpassing all other apes not only by learning more language, but by learning it without explicit training The first non-human animal to have learned a language without explicit training American psychologist Sue Savage-Rumbaugh and Kanzi's mother Matata using a keyboard labelled with geometric symbols First 6 symbols, then 18, finally 348 symbols referring to familiar objects (yoghurt, key, tummy), favoured activities (chase, tickle), even some abstract concepts (now, bad) The meaning of up to 3000 spoken English words Responding appropriately comments such as "put the soap in the water or carry the tv outdoor Comparing KANZI TO NIM CHIMPSKY AND WASHOE Kanzi compared to Nim Chimpsky Major differences between Nim and Kanzi,
Nim imitiating his trainers,
not adding anymore meaning than single signs,
interrupting conversations instead of taking turns Kanzi providing more information with longer utterances,
not repeating a word in a given combination,

Kanzi compared to Washoe Like Kanzi, Washoe would signed herself and with other chimpanzees Washoe had a foster son who was not trained by humans, but he learned more than 50 signs Unlike Kanzi, not displaying comprehension of what was being signed to her Using a lot of meaningless repetition In summary Learned language without being explicitly trained, •Used it to initiate conversations in the absence of rewards, •Spoke about other people and chimpanzees, •Was able to comprehend spoken speech, •Did not produce strings of words with meaningless repetition.
