Research on the communication skills of nonhuman primates reveals their inability to refer to objects that are not immediately present in their environment, such as food and danger. The ability to describe things and events that are not present is called:

Displacement

Explanation:

Displacement in psychology refers to the transfer ff thoughts, feelings and emotions to the target or less threatened person.

The misplacement ability of primates can be expressed in terms of aggressiveness and therefore displacement ability is considered as a defence mechanism in organisms.

The primates show displacement to other primates to describe any situation and the condition which is not present in the form of gestures.

Thus, displacement is correct.
