Sue Savage-Rumbaugh is known for teaching bonobos (apes) to use symbols for communication. Although unsuccessful in teaching one ape, Matata, Savage-Rumbaugh was surprised to discover that Matata's son, Kanzi, had learned to use the symbols, even though he had never had any direct instruction or reward. Kanzi's behavior most clearly shows that nonhuman primates can learn vicariously through observing others. observational learning is more powerful than classical conditioning. nonhuman primates learn best when reinforced on an intermittent schedule. negative reinforcement is more powerful than observational learning.

What is the difference between Koko the gorilla and Kanzi the bonobo's communication abilities? There is no difference. They both were taught American Sign Language. Koko uses a modified sign language while Kanzi uses a lexigram to communicate. Koko can communicate better than Kanzi. Kanzi has symbolic thought, whereas Koko does not. Koko demonstrates the ability to understand object permanence, whereas Kanzi cannot.

1. The increased brain size observed in the order Primates demonstrates the importance of intelligence in primate evolution and results in extended periods of nursing and development to accommodate increasing behavioral complexity. 2. The increased brain size observed in the order Primates results in shorter developmental periods to accommodate the necessary energy expenditures of larger brain size. 3.
