Monkeys show sophisticated learning abilities
...al but the monkeys needed to ignore their physical locations and touch them in the correct order. When the researchers began their study, they gave the monkeys three- and four-image lists, and once the monkeys showed proficiency in these lists, graduated to seven-image lists.
