Radical Exposure Tapping (RET) is a form of exposure therapy that can be used to quickly and effectively resolve memories of disturbing events that fuel PTSD, anxiety, fears, emotional reactivity and patterns of escalating conflict.  RET draws from the methodology of Eye Movement Desensitization and Reprocessing (EMDR) and combines it with the tapping sequence of the Emotional Freedom Technique (EFT) and imagery rescripting to produce an intervention that is more flexible than EMDR, provides greater theoretical and methodological rigor than using the EFT technique alone and can be effective in a single session.

Dr. Laurie MacKinnon developed RET by taking elements of EMDR and EFT combining them in a unique way and then analysing  and improving her effectiveness with this new method by video recording and reviewing dozens of RET therapy sessions
