Figure 11.16: Kanzi using the lexigram keyboard Each symbol on the keyboard is a word. When Kanzi, the bonobo, depresses a key, the symbol is illuminated both on the keyboard and on a larger screen that his caretakers can see. Kanzi also had a portable keyboard that he carried with him as he roamed a forested area with his caretakers. This photo was taken when Kanzi was still quite young, early during his language learning.
