The article says   Sue SavageRumbaugh 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   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 SavageRumbaugh explained to Kanzi that he would be given yogurt He was then asked to communicate this information to PanbanishaKanzi vocalized then Panbanisha vocalized in return and selected yogurt on the keyboard in front of herSavageRumbaugh tells me  These accounts are substantially different as you can see   In the source SR 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 isnt  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 SR cant tell Kanzi that he would be given yogurt Secondly Kanzi is supposed to understand  spoken English words thats according to the wiki bonobo article which references guess what the same Raffaele article were talking about so why does SR 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 cant find this experiment Tonight I contacted the Great Ape Trust where SR works with Kanzi and asked for the reference Ill let you know what they say Ill leave off amending the article in the meantime
