What is the term for teaching an animal an action in relation to another action?

The term defined in the question refers specifically to training an animal to perform one action in response to another action or stimulus. This is known as conditioning. Conditioning involves creating associations between different stimuli and responses, leading the animal to learn specific behaviors in relation to certain cues or actions.

In classical conditioning, for instance, an animal learns to associate a neutral stimulus with a significant one. In operant conditioning, behaviors are modified based on their consequences, such as rewards or punishments. This process is essential in behavioral training and helps to establish expected responses to specific commands or situations.

The other terms provided relate to different concepts in animal behavior and training. Reinforcement refers to the consequences that increase the likelihood of a certain behavior being repeated but does not specifically describe the relationship between actions. Habituation is a process where an animal becomes accustomed to a stimulus and stops responding to it over time, while socialization involves training an animal to interact appropriately with other animals and humans.
