Fj. Boster et al., THE RELATIVE EFFECTIVENESS OF A DIRECT REQUEST MESSAGE AND A PREGIVING MESSAGE ON FRIENDS AND STRANGERS, Communication research, 22(4), 1995, pp. 475-484
This study examined the role of the norm of reciprocity in mediating t
he relative effect of compliance-gaining message type on compliance in
interactions involving friends and strangers. Subjects received eithe
r a direct request to purchase raffle tickets or received the request
after having a favor done for them by a confederate, a pregiving messa
ge. Results indicate that friends comply more with requests than stran
gers and that their compliance is constant across message types. Among
strangers, the pregiving message produced more compliance than the di
rect request.
