Why are animals cognitive?

Chimpanzees cannot normally succeed in a task in which the rule is: whichever of two piles of food you point to, your companion gets, and you are left with the other. Trial after trial, a chimpanzee will point to the largest pile, only to be frustrated by the outcome: they simply cannot inhibit their natural attraction to the desired goal. But if Arabic numbers are substituted, they immediately solve the problem and switch to the lower number; if the test reverts to real entities, they again fail.

Streams of new data and theories, critically from neuroscience, are converging into a new, trans-species model of the psyche.
