Teaching sign language to a chimpanzee

Email Coby is not your average chimpanzee. It's true that the year-old chimp has a peculiar fascination with shoes, taking every opportunity to lure observers close enough to stick his fingers through the fence and feel their footwear.

Teaching sign language to a chimpanzee

Chomsky claims that humans possess an innate universal grammar that is not possessed by other species.

This can be readily demonstrated, he claims, by the universality of language in human society and by the similarity of their grammars. No natural non-human system of communication shares this common grammar.

Washoe (chimpanzee) - Wikipedia

Macphailcited by Pearce, made the claim that "humans acquire language and non-humans do not not because humans are quantitatively more intelligent, but because humans possess some species-specific mechanism or mechanisms which is a prerequisite of language-acquisition".

Some researchers have provided lists of what they consider to be the criteria that animal communication must meet to be regarded as language. For this lecture the list devised by Hockett is utilised, although this list is not the only such list available. Such Teaching sign language to a chimpanzee tend to be quite similar and certain elements of the Hockett list are considered particularly important in evaluating the question "can animals be taught language?

This applies to many animal communication systems, but there are many exceptions. Also, it does not apply to human sign language, which meets all the other 12 requirements. It also does not apply to written language. Broadcast transmission and directional reception: Rapid fading transitory nature: Signal lasts a short time.

This is true of all systems involving sound. It doesn't take into account audio recording technology and is also not true for written language. It tends not to apply to animal signals involving chemicals and smells which often fade slowly.

All utterances that are understood can be produced. This is different to some communication systems where, for example, males produce one set of behaviours and females another and they are unable to interchange these messages so that males use the female signal and vice versa.

The sender of a message also perceives the message. That is, you hear what you say. This is not always true for some kinds of animal displays. The signal produced is specialised for communication and is not the side effect of some other behaviour eg.

There is a fixed relationship between a signal and a meaning. There is an arbitrary relationship between a signal and its meaning. That is, the signal, is related to the meaning by convention or by instinct but has no inherent relationship with the meaning.

This can be seen in different words in different languages referring to the same meaning, or to different calls of different sub-species of a single bird species having the same meaning. Language can be said to be built up from discrete units eg.

Exchanging such discrete units causes a change in the meaning of a signal. This is an abrupt change, rather than a continuous change of meaning eg. Speech loudness and pitch can, on the other hand be changed continuously without abrupt changes of meaning.

Communicating about things or events that are distant in time or space. Bee dancing is an example of this. Language is an open system. We can potentially produce an infinite 2 number of different messages by combining the elements differently. This is not a feature of, for example, the calls of gibbons who have a finite number of calls and thus a closed system of communication.

Each generation needs to learn the system of communication from the preceding generation. Many species produce the same uniform calls regardless of where they live in the range even a range spanning several continents.

Such systems can be assumed to be defined by instinct and thus by genetics.


Some animals, on the other hand fail to develop the calls of their species when raised in isolation. Large numbers of meaningful signals eg. Human language is very unusual in this respect. Apes, for example, do not share this feature in their natural communication systems.

Teaching Language to Apes and other animals It seems well established that no animal communication system fulfils all of the criteria outlined by Hockett Chimpanzees can communicate in American Sign Language (ASL) to independent human observers whose only source of information is the ASL signs of the chimpanzees.

The Apes Who Learned Sign Language

Oct 30,  · Research into great ape language has involved teaching chimpanzees, bonobos, gorillas, and orangutans to communicate with human beings and with each other using sign language, physical tokens, and lexigrams (Yerkish).

Fouts wanted to observe if Washoe would teach the young chimpanzee sign language, and that is what happened.

In fact, Loulis learned approximately 50 signs from Washoe. It is interesting to note that Washoe taught signs to the younger chimp in the same manner she was taught. She molded his hands into the correct shape.
