3. Many people consider the use of language as a necessary attribute of intelligence. Koko is a gorilla trained by Dr. Francine Patterson of Stanford University in the use of American Sign Language. Koko was able to form word combinations for words unknown to her; for example, she represented the word ring by the words bracelet and finger, which she already knew. Does this gorilla’s possession of knowledge modify your thinking on the subject of animal intelligence? If so, then in what ways? Could you envision an intelligence test for Koko?
