An injured tennis player has to take a break from playing. While she is healing, she watches videos of other players. She pays special attention to the service mechanics of some of the top players in her league. When she plays her first post-recovery match, she is surprised at how well she can serve. What helped her tennis serve improve?

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.

Here, the tennis player was watching videos of others playing. When she was doing this she was storing all the visual stimulus. After she started to play again the mirror neurons converted the visual stimulus to motor action.

Hence, mirror neurons and observational learning were used here.
