Chimpanzees' (Pan troglodytes) use of gaze cues in object-choice tasks: different methods yield different results.

abstract：:Social animals have much to gain from observing and responding appropriately to the actions of their conspecific group members. This can in turn lead to the learning of novel behavior patterns (social learning) or to foraging, ranging, or social behavioral choices copied from fellow group members, which do not necessa...

Spatial memory allows animals to find a goal, such as a productive feeding patch, even when there are no goal-specific sensory cues available.

To solve the task, an animal must use a tool to push a piece of food out of a tube, which has a trap along its length. An animal may learn to avoid the trap through a rule based on associative processes, e.g. u...
