Meaningful Communication in Primates, Birds, and Other Animals6; Sternberg and Kaufman, 2002). Many experiments conducted with chimpanzees, gorillas, and orangutans have since underscored the belief that great apes have higher cognitive abilities, but the view that these might be unique to great apes amongst animals has become incresingly doubtful.

Increasing the Brain’s Capacity: Neocortex, New Neurons, and Hemispheric Specializationed according to brain size, and now there is revived interest in doing so, especially in ranking species according to both brain size and cognitive abilities. It is timely, therefore, to see what light these studies, with emphasis on the recent ones, might shed on our topic of debate, “Are primates special in terms of their cognitive abilities?”
