The Development of Numerical Competence

The area of animal counting has historically been the subject of a long and colorful debate, but only more recently have systematic, more rigorous experimental efforts to evaluate numerical abilities in animals been undertaken. This volume contains chapters from investigators in a range of disciplines with interests in comparative cognition. The studies described characterize the emergence of number-related abilities in rats, pigeons, chimpanzees, and humans, bringing together -- for the first t
