Answer:
mirror neurons and observational learning
Explanation:
Mirror neurons are the neurons in our body that fire when we try mirror the action of another organism. When we are observing something and are trying to learn it the mirror neurons help us to convert the visual stimulus to motor actions in our body. This entire process is called observational learning.
