- Savage Rumbaugh
- The aim was to study the ability of chimpanzees to learn language
- The sample was two pigmy chimpanzees (Kanzi and Mulika) compared with two common chimps (Sherman and Austin)
- It was a longitudinal study over a 17 month period
- IV: two pigmy chimpanzees compared with two common chimps
- DV: language acquisition
- The chimps were taught language using a visual graphic symbol system called a Lexigram, consisting of symbols that light up and a voice synthesizer
- For a new word to be considered learned it would have to be 9/10 correct.
- The data is qualitative and is easy to analyse and compare
- The study could be improved by having a bigger sample so it is more generalised
- It lacks ecological validity because the chimps were not in natural enviroment
