Final answer:
Latent learning is learning that is not immediately apparent and is only demonstrated when there is motivation to perform the learned behavior.
Step-by-step explanation:
Latent learning is defined as learning that occurs without immediate reinforcement or overt behavior change, and it might not become evident until there is a specific need or motivation to demonstrate the behavior. An example of latent learning can be observed when children watch their parents perform a task, such as driving a specific route, but do not show evidence that they have learned this task until they are required to perform it themselves, often at a later time.
Therefore, the correct answer to the student's question is: Latent learning is d. not demonstrated until motivated to perform the behavior.
