- 1more ecological validityhowever teaching a chimp a language is itself not ecologically valid as human- chimp interaction would not occur in everyday life
- 2counterargument ecological validityhowever, as washoe taught her adopted son louislis the language, in increases ecological validity because it is chimp-chimp interaction meaning we can generalise results to real life.
- 3internal reliabilitylow as it was only done on washoe and was not repeated, this is a weakness as we cannot see if results are consistent and therefore reliable or not meaning our predictions may not be reliable
- 4counterargument internal reliabilityalthough, they had three different observers who observed each sign washoe learnt (didn't know the aims of the study) inter-rater reliability therefore increasing it slightly
- 5ethicsWashoe was taken out of her natural habitat to do something unnatural to her (learn ASL). this is bad as it could have put her under psychological harm which she would not have been under in real life
- 6counterargument ethicsalthough Washoes companions as well as Gardner and Gardner commented on how happy and chirpy Washoe was.
- 7Time validitylow as it was not repeated since it was carried out in 1969. weakness, times may have changed along with the ability of chimps to learn a language so cannot generalise results to diff time eras
- 8time validity counterargumentSavage-Rumbaugh in 1994 carried out similar study on a lexigram with a Bonobo, taught 500 words and showed a clear understanding of complex human sentences suggesting animals can learn lang.
- 9What 5 things would you include about the methodology?Internal validity
Ecological validity
Time validity
Internal reliability
Ethics - 10Internal validitylacks due to it not controlling any extraneous variables as well as not having Washoe from birth. in their conclusion they were unable to state whether she had learnt a language or not
- 11internal validity explainweakness as we cannot establish a true cause and effect therefore we do not know if chimpanzees can learn a language
- 12counterargument internal validityhowever said washoe learnt 133 signs which she taught to her adopted son Louslis which was correct ASL, therefore chimps can learn a language
- 13ecological validitydid not live in the G&G household all the time, as they wanted it to be as natural as possible for Washoe. raised her as though she was a deaf child
