Transcript of Copy of Savage Rumbaugh et. al
The results suggest that pygmy
chimpanzees exhibit symbolic and auditory perceptual skills that are distinctly different from those of common chimps.
The researchers comment that it is surprising that two closely related species differed so greatly in their capacity to acquire a functional symbolic communication system, specifically in their ability to comprehend speech WALT: Gain a better understanding of language acquisition
Understand to aim, method, procedure, results and conclusion of this study.
Be able to evaluate and write a PEC for this study. WALT: AIM:
To study the language acquisition of two pygmy chimpanzees Kanzi and Mulika,compared with
two 'common' chimpanzees
Austin and Sherman. METHOD:
Study reports on a 17
month period. The main medium of communication with all animals was a visual symbol system, a lexigram consisting of geometric symbols that brighten when touched, which is treated as the equivalent of uttering a word. FINDINGS:
Untutored gestures by Kanzi and Mulika. For
example, the pygmy chimps pushed a balloon
to the researchers mouths.
After 17 months, Kanzi got 2540 combinations correct and 256 were imitated.
Kanzi and Mulika's gestures were often more explicit than Sherman's and Austin's, for example if Kanzi wanted a hard nut opened, he would offer it to a person. if the person did not understand that this was a request to crack the nut with his hand, followed by taking a small rock and placing it on op of the rock and illustrate what he wished to have done. SAMPLE:
2 pygmy chimps:
Kanzi and Mulika
2 common chimps:
Austin and Sherman
Pygmy chimps were chosen because they already hpossessed some of the language acquisition that common chimps didnt ACROSS
4. How many months did the case study go on for?
5. One of the pygmy chimps
7. What were recorded?
1. Also known as the pointing board
2. Language any means of communication, as between speakers of different languages, using gestures.
3. Was this crossword good?
6. oral communication: STARTER-CROSSWORD Language vs Communication
Language is a system of symbols (words / sounds) which convey meaning.
Communication is the transmission of ‘something’ (a message, signal) from one location to another.
Some form of language is necessary for communication.
Linguistic universals are present in all languages. - Can animals communicate (with one another / with us?)
- Do animals have language? SYMBOLS AGE ACQUIRED (MONTHS) 30 33 32 Orange, peanut, banana, apple, bedroom, chase, Austin (cc) image by anemoneprojectors on Flickr Sweet potato, raisin, ball, cherry,

When outdoors, Kanzi and Mulika used laminated copies of these lexigrams which served the same purpose and they had to point to a diagram and then locate where it was in the garden. For example, Savage-Rumbaugh was able to demonstrate that two common chimpanzees called Sherman and Austin were able to use representational (or referential) symbol learning. Representational (or referential) symbol learning occurs when an individual can refer to the objects when there are no contextual cues to provide association, for example being able to respond to the request ‘get your ball’ even if the ball is in another room. So, what did Savage Rumbaugh
want people to understand
about animal learning?... THE STUDY: KEY WORDS: DISPLACEMENT: The ability to speak about the present, past and future. ARBITARINESS There is no natural connection
between a word or sound and the thing it denotes. Write one advantage and one disadvantage
of the study by Savage Rumbaugh.
