Desensitizing

A part of debriefing, it is an attempt to remove any undesirable consequences of participation in research through restoring the participant to a state of emotional well-being following deception.  There is evidence that desensitizing does not always this goal as participants can be made aware of any unflattering behavior they may have revealed during an experiment.  In a completely different context, there is systematic desensitisation: a technique employed in behavior therapy for treating phobias, and devised by Joseph Wolpe (1915-1997).
