Final answer:
Reminding someone of past favors or trading favors to influence them is known as reciprocal tactics, not coalition tactics. Coalition tactics involve grouping to persuade, while reciprocal tactics rely on the principle of reciprocity.
Step-by-step explanation:
Reminding someone of past favors or offering to trade favors as a method to influence them is known as reciprocal tactics rather than using coalition tactics. Coalition tactics involve seeking the aid of others to persuade the target to agree. It's similar to forming a group with the same interests to gain greater influence. In contrast, reciprocal tactics are based on the principle of reciprocity, where one party is more likely to comply with a request if they feel they are repaying a favor or are in a position to expect one in return.
