Research and Sources
Most parenting content says "research shows" and stops there. This page is where I show the work.
Every source below is a real paper you can look up. Where a study measured something narrower than the claim it supports, I say so. Where something is my clinical judgment rather than a finding, I say that too, because those are different things and you deserve to know which one you are getting.
If I ever make a claim you cannot find here, ask me. I would rather be asked.
The Presence Protocol
What the guide says: when you are flooded, the thinking part of your brain becomes less available and threat processing takes over.
The source: Kredlow, M. A., Fenster, R. J., Laurent, E. S., Ressler, K. J., & Phelps, E. A. (2022). Prefrontal cortex, amygdala, and threat processing: implications for PTSD. Neuropsychopharmacology, 47(1), 247-259.
What it actually is: a review of how prefrontal regions and the amygdala interact during threat, written with PTSD in mind. The mechanism it describes is general. The clinical population it was written for is not. Nothing in it is about parents in a kitchen at 7am.
What the guide says: naming what you feel reduces the intensity of the reaction.
The source: Lieberman, M. D., Eisenberger, N. I., Crockett, M. J., Tom, S. M., Pfeifer, J. H., & Way, B. M. (2007). Putting feelings into words: affect labeling disrupts amygdala activity in response to affective stimuli. Psychological Science, 18(5), 421-428.
What it actually is: a brain imaging study of adults looking at emotional images in a lab and labeling what they saw. Labeling reduced amygdala activity and engaged prefrontal regions. It is not a study of parents, not a study of real stress, and not a study of anyone mid-conflict. The finding is solid and the setting is artificial, and both of those are true at once.
What the guide says: emotion can be deliberately regulated, and which strategy you use changes the result.
The source: Ochsner, K. N., & Gross, J. J. (2005). The cognitive control of emotion. Trends in Cognitive Sciences, 9(5).
What it actually is: a review article summarizing how deliberate regulation strategies work and differ. It is the map, not a single experiment.
What the guide says: a parent's state and a child's state influence each other physiologically.
The source: Bornstein, M. H., & Esposito, G. (2023). Coregulation: a multilevel approach via biology and behavior. Children, 10(8), 1323.
What it actually is: a review of coregulation across biological and behavioral levels. It supports that caregiver and child states influence one another. It does not establish a specific neural mechanism for it, and I am not claiming one.
What this research does not say
This section matters more than the one above it.
No study has tested the Presence Protocol. The four steps are my own synthesis, built from the findings above plus what I see in practice. The underlying pieces are evidenced. The sequence is mine.
The affect labeling work is adult laboratory research. It is good research. It is not evidence about what happens in your hallway during a meltdown, and I am not going to pretend otherwise.
Co-regulation is well supported. The popular explanation for it is contested. You have probably heard "polyvagal" used as the mechanism behind co-regulation. The observable phenomenon, that a child's body responds to a caregiver's state, is well evidenced. The specific anatomical and evolutionary account behind the polyvagal label is disputed in the literature, with a substantial published critique and a rebuttal from its author. I use the model because it describes something real and useful. I do not call it settled neuroscience, because it is not.
Nothing here is a diagnosis or a treatment. I am a child and adolescent development specialist, not a physician or a therapist.
