Final answer:
Imitation is a learned behavior supported by Epstein's experiments on direct and delayed spontaneous imitation.
Step-by-step explanation:
Epstein's experiments on direct and delayed spontaneous imitation support the idea that imitation is a learned behavior. Learning, unlike innate behaviors such as reflexes and instincts, involves acquiring knowledge and skills through experience. Epstein's experiments showed that imitation can be acquired through observation and copying, which suggests that it is a learned behavior.
