Unveiling the Science Behind Energy Psychology: How Tapping Works

David Gruder, PhD, DCEP • February 17, 2025

David Feinstein, not to anyone’s surprise, has contributed yet another groundbreaking paper to the field of energy psychology. This one focuses on the physiological mechanisms that appear to explain how tapping actually works. While empirical verification of effectiveness is vital—and we’ve come a very long way toward establishing that—it’s a bit more complicated to credibly pinpoint the physiology behind those results.

Dr. Feinstein’s latest article, "Physiological Mechanisms of Energy Psychology Treatments: An Updated Synthesis," was just published in the journal Energy Psychology. It presents seven empirically supported premises that elucidate the biological basis for the clinical improvements we consistently see when using energy psychology techniques.

 

The Journey from Skepticism to Scientific Validation

The energy psychology field, including its most well-known method, Emotional Freedom Techniques (EFT), has come a long way since its inception in the 1980s. Met with strong skepticism for a long time, and often wrongly dismissed as pseudoscience, this approach has gained significant traction in clinical practice and academic research. This credibility has been fortified by over 200 peer-reviewed clinical trials supporting its efficacy, on top of millions of downloads of the EFT mobile app worldwide.


The challenge for energy psychology, however, has always been explaining its mechanisms in ways that align with modern scientific understanding. Early explanations often relied on concepts from traditional Eastern medicine, such as "meridians" and "subtle energies," but these concepts have been difficult to verify using conventional scientific methods.


Feinstein's paper marks a significant shift in this narrative. It provides a comprehensive synthesis of current research that explains energy psychology's effectiveness through the lens of Western science.

 

The Backbone of Energy Psychology's Efficacy: Seven Key Premises

Feinstein's paper outlines seven empirically supported premises that unveil the physiological mechanisms underlying energy psychology treatments. His focus is on methods that use acupoint tapping, like Emotional Freedom Techniques and Thought Field Therapy.


  1. Biological Markers of Improvement: Clinical improvements following acupoint tapping sessions are consistently reflected in measurable, clinically desirable biological shifts. These include reduced cortisol levels, lowered blood pressure, favorable changes in gene expression, and improved heart rate variability.
  2. Generation of Electromagnetic Signals: The act of tapping on acupoints generates electromagnetic signals through a process known as "mechanosensory transduction," in which mechanical pressure is converted into electrical signals.
  3. Signal Transmission to the Brain: These electromagnetic signals are transmitted to the brain via two primary pathways: the nervous system and the body's connective tissue network.
  4. Targeted Brain Activation: The signals reach the brain regions that are aroused by the thoughts, memories, and images the client focuses on during the tapping process.
  5. Neurological Regulation: Once reaching the brain, these signals help regulate brain activity, either increasing or decreasing activation in ways that promote healing and adaptive behavior.
  6. Alignment with Memory Reconsolidation: The process aligns perfectly with scientific understanding of memory reconsolidation, which is the way the brain updates old learnings with new experiences.
  7. Increasing the Effectiveness of Exposure Techniques: Psychological exposure is one of the most potent treatments for trauma-based disorders, and combining this with tapping sends signals directly to the limbic system that down-regulate arousal, making exposure treatments even more rapid and effective.


The Neurobiological Dance of Tapping

Feinstein's synthesis draws from multiple scientific disciplines beyond psychology to paint a comprehensive picture of how tapping works at the neurobiological level. Imaging studies cited in his paper reveal fascinating insights into the brain's response to tapping:


  • An fMRI study showed decreased arousal in brain regions associated with pain perception after tapping sessions.
  • Another study, which also used fMRI pre/post treatment measures, found reduced activation in neural areas linked to food cravings after tapping treatments for obesity.
  • Other imaging studies suggest that the technique appears to facilitate the integration of negative emotional experiences at a neural level


These findings not only substantiate the subjective experiences reported by clients but also provide a scientific foundation for the observed clinical improvements.

 

Implications for Psychotherapy

Understanding these mechanisms has profound implications for psychotherapy. For instance, the knowledge that tapping generates electromagnetic signals that travel to aroused brain regions underscores the importance of having clients focus on specific aspects of their problems while tapping. This clarity can enable practitioners to fine-tune their techniques for maximum efficacy.


Moreover, understanding how tapping facilitates memory reconsolidation can help clinicians recognize and capitalize on moments when old beliefs become more flexible and receptive so change can occur. This, in turn, can lead to more targeted and effective interventions.


Future Research Directions

While Feinstein's paper provides strong scientific support for energy psychology's mechanisms, it also highlights areas where further research is needed. He suggests some directions for future studies, including:


  • Direct measurement of the electromagnetic signals generated by tapping.
  • Real-time tracking of signal propagation through the body during tapping sessions.
  • More detailed mapping of the neural pathways involved in the tapping response.


Such studies should be able to further refine our understanding of energy psychology's mechanisms and potentially lead to even more effective treatment protocols.

 

Conclusion: A New Era for Energy Psychology

We stand on the brink of a new era in mental health treatment—one that more fully demonstrates in accepted scientific ways, that energy psychology methods do indeed harness the body's own electromagnetic and more subtle energy systems to promote healing and well-being. Feinstein’s latest paper marks a next big milestone in advancing this emerging trend. By providing a scientifically grounded explanation for the efficacy of energy psychology techniques, it opens the door for broader acceptance and integration of these remarkable methods into mainstream psychotherapeutic practice.


For practitioners, this “how it works” research offers an even more solid foundation for explaining their work to scientifically-minded colleagues and clients alike. For researchers, it provides a roadmap for future investigations that can further refine and expand our understanding of these powerful techniques.

After retiring from the military, I conducted individual and group therapy with combat veterans as a clinical social worker for the Department of Veterans Affairs (VA) at the VET Center in Warwick, RI. In my work, I've had many experiences showing the power of energy psychology to help heal trauma . One of these amazing stories occurred during my tenure at the VA. Veteran suffers from PTSD A 70-year old Vietnam Veteran suffered for 45 years from chronic PTSD as a result of life-threatening events he endured and injuries he sustained during combat. Let's call him Joe (not his real name). His symptoms included nightmares and waking up profusely sweating every night since he returned from the war 45 years ago. Joe also had insomnia and anger issues. Conventional therapies and medication were not able to alleviate the adverse impact of his trauma. Unfortunately, Joe's experience is common among a vast number of Veterans receiving treatment for PTSD at the VA. Energy psychology resolves trauma-related symptoms In the first energy psychology session, I introduced Joe to Emotional Freedom Techniques (EFT) and explained the process and its efficacy. During the next 6 sessions, he tapped on the EFT meridian points for 2-3 rounds on each combat trauma we addressed. While he tapped, I guided him to verbally release related negative emotions. We did this until he no longer experienced any disturbance associated with these challenging events, as determined by muscle testing. The results were inspiring. At the end of six 50-minute sessions, Joe reported that his nightmares and night sweats completely stopped, and he felt more rested, peaceful, and significantly less anxious. Joe was even able to stop taking most of his anxiety and depression medication. His wife said she noticed a huge positive shift in his demeanor. Lasting results Over the next 3 years, Joe used EFT on his own to clear other developmental traumas and negative core beliefs. During this time, he only had four nightmares during one two-week period, which were triggered by watching a war movie. Afterwards, he did not have any recurrence of PTSD symptoms. Joe felt joy that he did not experience previously, and he was more emotionally open and affectionate with his wife. This heart-warming story shows the power of EFT to heal rapidly and effectively, with results that last. It's why I love using it. Going forward What a difference could be made with Veterans and their families if the VA and Department of Defense (DOD) used energy psychology techniques like these! They would be free of the devastating impact of PTSD, have better relationships and an improved quality of life. Many ACEP members have stories of hope and healing. Let’s share them! When we tell our stories, we can help inspire practitioners to adopt energy psychology methods that are powerfully grounded in effective healingwith long-lasting outcomes.
