Study of Hamadryas Baboons ( Papio Hamadryas) Ability to Solve Object Manipulation Tasks.

Cognitive ability to solve object manipulation tasks was evaluated by 'string pulling' and 'transparent tube' tests. The string pulling task was solved by 7 of 11 animals. The task of object extraction from the tube was too difficult, not a single animal solved it. The authors conclude that Hamadryas baboons demonstrated rather poor ability to solve object manipulation tasks. [ABSTRACT FROM AUTHOR]
