Describe the elements that make foot-in-the-door and door-in-the-face sequential persuasion techniques work successfully.

What will be an ideal response?

Foot-in-the-door works most successfully for prosocial reasons, when different people make each request, and when no material incentives are provided. Door-in-the-face works best for prosocial reasons, when the same person makes both requests, and when there is a relatively brief delay between requests.
