托福口语 Task 4

Now let's talk about a fascinating behavioral adaptation in animals called 'displacement behavior.' This occurs when an animal faces a conflict between two strong urges, and instead of resolving the conflict, it performs a seemingly irrelevant action. The main point is that displacement behavior helps animals cope with stress or conflicting motivations by redirecting their energy into a safe, non-threatening activity. Consider the example of the three-spined stickleback fish. During mating season, a male stickleback aggressively defends its territory from other males. But when a rival male approaches, the resident male faces a conflict: fight or flee. Instead of attacking, it may suddenly perform a displacement behavior—it will swim to the bottom and dig a small pit in the sand, as if preparing a nest, even though it has no intention to nest at that moment. This action reduces tension and allows the fish to reassess the situation. Another example comes from humans. When people feel nervous in a social situation, such as giving a public speech, they might start adjusting their clothing, touching their hair, or tapping their fingers. These are displacement behaviors that help relieve anxiety and manage the conflict between the desire to perform and the fear of judgment. So, in both cases, displacement behavior serves as a coping mechanism to deal with internal conflict or stress.
