Final answer:
The two compliance techniques that involve reciprocity are door-in-the-face and that's-not-all. Door-in-the-face technique involves making a large request followed by a smaller one, and that's-not-all technique adds extra incentives to make an offer more attractive.
Step-by-step explanation:
The two compliance techniques that specifically involve reciprocity are door-in-the-face and that's-not-all.
Door-in-the-face technique is a persuasion strategy where a person makes a large request that is likely to be refused, and then follows it up with a smaller request. The person is more likely to comply with the smaller request because they feel obligated to reciprocate the concession made by the persuader.
That's-not-all technique involves making an initial offer and then adding extra incentives or bonuses to make the offer seem more attractive. This technique makes use of reciprocity by giving the individual the feeling that they are getting a better deal.
