Brefczynski-Lewis Lab studies how we perceive people we love and people we don’t like, both famous and political, and how training in compassion can affect those perceptions. The Lab is examining the neural and physiological correlates of the liked and disliked persons and how these change after training in compassion. Grudge forgiveness study: fMRI response to the face of the grudge person, as well as cardio and reactive measures will be tested before and after the intervention.
