While the chimpanzees outperformed human adults in memorizing briefly presented numbers that appeared on the screen, [1] the researchers found that chimpanzees were less proficient at a variety of other cognitive tasks including imitation, cross-modal matching, symmetry of symbols and referents, and one-to-one correspondence. Matsuzawa came up ...
Recently, most non-human theory of mind research has focused on monkeys and great apes, who are of most interest in the study of the evolution of human social cognition. Research can be categorized in to three subsections of theory of mind: attribution of intentions, attribution of knowledge (and perception), and attribution of belief.
While a monkey is used as a mechanism for the thought experiment, it would be unlikely to ever write Hamlet, according to researchers.. The infinite monkey theorem states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type any given text, including the complete works of William Shakespeare.

A monkey drinking Frooti from a juice box using its hands. The mind and behavior of non-human animals has captivated the human imagination for centuries. Many writers, such as Descartes, have speculated about the presence or absence of the animal mind. [7]

Less is known about variation on scales less than total brain volume. A meta-analytic review by McDaniel found that the correlation between intelligence and in vivo brain size was larger for females (0.40) than for males (0.25). [18]
