生命科学——动物行为学科
Displacement activities occur when an animal experiences high motivation for two or more conflicting behaviors: the resulting displacement activity is usually unrelated to the competing motivations. Birds, for example, may peck at grass when uncertain whether to attack or flee from an opponent; similarly, a human may scratch his or her head when they do not know which of two options to choose. Displacement activities may
also occur when animals are prevented from performing a single behavior for which they are highly motivated. Displacement activities often involve actions which bring comfort to the animal such as scratching, preening, drinking or feeding.
