- Trained a Chimpanzee called 'Nim Chimsky'
- Recorded on tape, over 200,000 communications from Nim
- During a 2 year period
- Concluded that there was a marked difference between Nim's communcation + child language
- Concluded = Nim wasn't using the equivalent of human language
- Nim Chansky's language acquistion appears to be the result of 'parrot fashion' learning RATHER than a meaningful acquistion of language

- Washoe had an adoptive son, Loulis
- Researchers only signed 7 words to him
- Loulis acquired his vocabularly of over 50 signs from other chimpanzees he lived with
- (Washoe, Moja, Tatu + Dar)
- mirroring the manner in which human children learn language.
This supports G&G, as it shows the chimps must have learnt and understood the signs, to be able to teach Loulis.
Furthermore, it shows how chimps can acquire language, as Loulis evidently learnt 50 signs.
