Mirror neurons
Explanation:
Mirror neuron: The term mirror neuron is defined as a neuron which is responsible for firing in both the conditions i.e when an individual or an animal acts on something as well as when he animal or an individual tends to observe the similar actions being performed by another person. Therefore, the specific neuron tends to 'mirror' a particular behavior led by someone else as if the observer himself or herself is acting.
In the question above, the given statement represents that Anna's method of learning is determined by the mirror neurons.
This example illustrates the foot-in-the-door technique.
This refers to the fact that if you manage to convince somebody to do a small favor for you, they will be more likely to help you with something more engaging and important as well. As you can see here, Maria helped Nat with one lesson, but then she was more willing to help him with three.
