redress this situation by examining the methodological and ethical issues
concerning deception and debriefing from a process perspective. We review t
he past research on deception and debriefing, identify key psychological pr
ocesses by which deception and debriefing influence participants, and prese
nt a framework for understanding the effects of both deceptions and debrief
ings on research participants. We then show how the results generated from
this framework can be examined from an ethical perspective to provide a bet
ter understanding of the benefits and costs of the research to all stakehol
