The article says Sue Savage Rumbaugh has observed Kanzi in communication to his sister In this experiment Kanzi was kept in a separate room of the Great Ape Project and shown some yogurt Kanzi started vocalizing the word yogurt in an unknown language his sister who could not see the yogurt then pointed to the lexigram for yogurt 5 Now in this case TG there is a clear misrepresentation of the source which reads In one experiment she described to me she placed Kanzi and Panbanisha his sister in separate rooms where they could hear but not see each other Through lexigrams Savage Rumbaugh explained to Kanzi that he would be given yogurt He was then asked to communicate this information to Panbanisha Kanzi vocalized then Panbanisha vocalized in return and selected yogurt on the keyboard in front of her Savage Rumbaugh tells me These accounts are substantially different as you can see In the source S R explains to Kanzi through lexigrams that he would be given yogurt in the article he is shown the yogurt In the source Kanzi is asked to tell Panbanisha that he would be given yogurt in the article he isn t In the source Kanzi simply vocalizes in the article he vocalizes in an unknown language Why is the wiki article simplified in this way Because the claims in the source are incredible As far as I know lexigrams do not include words such as would so S R can t tell Kanzi that he would be given yogurt Secondly Kanzi is supposed to understand 3000 spoken English words that s according to the wiki bonobo article which references guess what the same Raffaele article we re talking about so why does S R need to use the lexigram at all More importantly both the article and the source refer to this experiment It would be nice to know the details of this experiment which might describe how many objects Kanzi was shown how often he vocalized and how many times Panbanisha responded with accuracy and so on I can t find this experiment Tonight I contacted the Great Ape Trust where S R works with Kanzi and asked for the reference I ll let you know what they say I ll leave off amending the article in the meantime
