  1. Savage-Rumbaugh Results and evaluation

  2. D A B F Results

  3. Results • 2530 correct combinations • many were ‘two foods’, e.g. hotdog and coke • 265 imitated • Person (g) chase Kanzi’ person (g) chase person (g)g = gesture to indicate ‘who’ indicates structure dependence / correct syntax Example combinations

  4. Testing Kanzi • Given lexigram and/or photo • Asked to match to object • Also match to spoken English • See example list

  5. Kanzi: comparison of imitated or spontaneous to ‘other ape learners’

  6. Conclusions Kanzi learned to use the symbols spontaneously Compared to other species of chimps pygmy chimpanzees appear to be able to learn and use language more like a human child Kanzi & the language universals? Semanticity - YES Creativity - YES Structure dependence - YES Generalisation - YES Displacement - YES

  7. Section A questions 1. Identify the FOUR Chimpanzees studied by Savage-Rumbaugh.[4] 2. Explain why the chimpanzees used lexigrams rather than spoken language to communicate with humans.[2] 3. Outline TWO methods that were used to record the lexigrams used by the chimpanzees.[4] 4. Describe TWO differences between language acquisition of pygmy chimpanzees and common chimpanzees.[4] 5.Outline ONE ethical concern that could be raised in relation to this study [2] 6. Describe why the chimpanzees used in this study may not have been representative of their own species.[2] 7. Outline why this study can be described as a longitudinal case study [2] 8. Describe TWO methods used by Savage-Rumbaugh to test the chimpanzees’ ability to comprehend lexigrams.[4]

  8. Evaluation: Choose 4 evaluative issues from the list below and write them out in the PEC format ...

  9. Evaluative issues: ++ both quantitative and qualitative data ?? validity of measurement ?? reliability of measurement ?? representativeness of sample ?? ecological validity (level of realism) ?? generalisability to other pygmy chimps ?? ethical issues ?? differences between Kanzi & child learner ?? usefulness

  10. Changes and Implications: In your 5 groups, suggest a change and an implication-Score out of 5, Best group wins a prize for their team! Write down top 2 scoring groups
