Negotiators can use reinforcement to shape the behavior of the party they are negotiating with. Reinforce behavior immediately after it occurs—don’t delay reinforcement. Withhold reinforcement from any behavior you do not want the other side to use—just don’t respond. Forms of social reinforcement are simple, nonverbal gestures such as nodding, smiling, and eye contact. More direct reinforcements are statements such as: “I like that.” “This could work.” “That is interesting.”
