Answer:
rule of reciprocity.
Explanation:
The rule of reciprocity refers to the social norm in which you feel obligated to do something for the person in response to what that person has done something for you. The concept of rule of reciprocation was developed by Robert Cialdini in his book titled "Influence: Psychology of Persuasion."
According to this principle, it is a universal habit in humans that one feels obligated to reciprocate to an act of generosity that has been offered by others either in a form of a material gift or a good deed. The rule of reciprocation is also used as a tool to persuade.
