Final answer:
American negotiators tend to exhibit friendly interactions during the persuasive stage of negotiation, using persuasive strategies and seeking common ground.
Step-by-step explanation:
American negotiators tend to exhibit friendly interactions during the persuasive stage of negotiation. Rather than using force, they seek to win over the other party or parties to comply with their wishes. This can involve employing persuasive strategies such as the foot-in-the-door technique, where negotiators get the other party to agree to a small favor or request before making a larger ask. American negotiators also aim to find common ground and make compromises that are acceptable to all parties involved.
