‘Acting Out’ Behavior of Traumatized Children, through the Lens of Polyvagal Theory

Recently I have been learning, or trying to learn may be more accurate, about polyvagal theory. I am thinking about its application in work with traumatized children and young people. Although, what I have understood so far is relevant in many other areas of life and work. I have been reading Stephen Porges (2017) – The Pocket Guide to the Polyvagal Theory: The Transformative Power of Feeling Safe. As the 2nd part of the title implies, this is fundamental to working with trauma, and hence my interest. If the title of Porges’ book suggests easy reading, i would say it is not, but it is written clearly, and I am finding it very helpful.

Learning a new theory is always a challenge, but when a theory is connected to our own experience it is easier to conceptualize.  It also helps us when a new theory fits well on the top of other theories, which we already understand well. Development is usually incremental.  I believe in the practical implications and use of theory. As Kurt Lewin (1943) a pioneer in organizational psychology famously noted, there is nothing so practical as a good theory.  Tongues (2016, p.80) succinctly states the usefulness of a good theory, 
A theory is an explanation, a set of ideas about how something works, and the practical application of good theory can be invaluable.
I think polyvagal theory is very useful in helping us understand some complex issues. So, I am going to try and apply it to something i have been talking about recently – the meaning of ‘acting out’ behaviour of children who have suffered complex trauma. In particular, the phenomena of ‘running away’ behaviour, which i wrote about in a previous blog (Tomlinson, 2015a).

Porges explains that a vagal pathway (nerve) is part of the autonomic nervous system and poly means there are many of them. The vagal pathways function to protect safety. They alert the person to threat and mobilize a protective response. This happens at an unconscious level, which Porges refers to as neuroception.  In other words, it is the nervous system that is identifying threats to safety, as well as opportunities for enhancing safety and well-being. Dana (2018) explains, 
Neuroception results in the gut feelings, the heart-informed feelings, the implicit feelings that move us along the continuum between safety and survival response. Neuroception might be thought of as ‘somatic signals that influence decision making and behavioral responses without explicit awareness of the provoking cues’ (Klarer et al., 2014, p.7067).
When we are in danger neuroception takes charge and over-rides our thought processes. This was demonstrated to me vividly in a personal experience.  I was on a beach in Israel where a group of soldiers had set up a temporary camp.  Suddenly, I heard a loud bang behind me. Before I knew it, I was sprinting and ended up about 30 yards down the beach.  I was safely in the sea before I stopped to turn around.  Thankfully no-one was injured.  There had only been a minor explosion of a small cooking gas canister and nothing more sinister.  I remember wondering how I moved so quick and so far without even thinking.  Good job my neuroception was working well and gave the orders to flee! 

Problems arise when the vagal pathways have been impacted by trauma, especially of the complex kind. The neuroception becomes hypervigilant, misreads situations and may respond to safe situations as if they are dangerous. We know this well in our work with trauma. 

Theoretical understanding of the centrality of safety in healthy development and treatment is not new. Bowlby (1952, 1988) explained the concept of how a secure base is the starting point of healthy development during infancy. In the treatment of trauma, Pierre Janet in the 19th century, outlined that safety/ stabilization was the first phase of treatment followed by processing and integration (Kezelman and Stavropoulos, 2012).  

In work with traumatized children and others, safety is the starting point.  The child must actually be safe and then reach the point where he/she also feels safe.  Feeling safe is not the same as being safe. It might take a year or longer of being safe, before he/she begins to feel safe. And there will be plenty of ups and downs along the way. Before connections can be achieved, safety must be established. Only when a disconnected or unconnected child begins to feel safe will he/she be able to take the risks involved in connecting. Once the process of connecting begins the child is moving towards integration.  
The foundations of well-being can be considered as safety, connection and integration (Tomlinson, 2015a).  
A brief look at Porges’ breakdown of the autonomic nervous system, into three distinct functions helps elaborate our understanding of safety. The oldest part of the nervous system is the dorsal vagal circuit, which developed over 500 million years ago. It can be considered reptilian in its nature. This is part of the parasympathetic nervous system. The dorsal vagus takes hold when a person feels trapped and in life-threatening danger. The typical responses include, freezing, becoming immobile, fainting and appearing dead. The aim is to be still, to avoid attack. And if attacked the heart rate and breathing are slowed, blood is withdrawn from the surface of the body to the organs. This is a survival, energy conserving response making death less likely if attacked and injured.  

Another feature of the dorsal vagal circuit is dissociation. This is where the person who is physically trapped in a traumatic situation becomes psychically removed from their body.  Again, this is not a conscious process.  Sometimes afterwards a person talks about being outside of their body, observing what was happening but not feeling the pain.  It is also possible that they may have no conscious memory of the event. Dissociation is a protective function, but if repeated regularly it can begin to have serious consequences for healthy functioning.  As Van der Kolk and Newman (2007, p.7) state,
 …posttraumatic syndrome is the result of a failure of time to heal all wounds. The memory of the trauma is not integrated and accepted as a part of one's personal past; instead, it comes to exist independently of previous schemata (i.e., it is dissociated).
I was fortunate to begin my work at the Cotswold Community, a therapeutic community in England. It was for boys who had suffered complex trauma. The therapeutic approach was based on the work of Psychoanalyst and Pediatrician, Donald Winnicott. Our consultant Barbara Dockar-Drysdale (1958) had developed the concept of a ‘frozen’ child. This was one of the syndromes of deprivation (1970, 1970a), that children developed as defence mechanisms in response to repeated trauma, including neglect and abuse. A ‘frozen’ child usually had the most serious levels of abuse and neglect often from birth.  I think the frozen child had much in common with a child whose dorsal vagal circuit is hypervigilant. Dockar-Drysdale explained her preference for the term ‘frozen’ rather than ‘affectionless’, which was also used at the time, because, 
…‘affectionless’ sounds final, but a thaw can follow a frost.
A thaw of something frozen inevitably means movement. This progression can also be linked to the second part of our autonomic nervous system, which developed 400 million years ago. This is the sympathetic nervous system and is mobilized in response to danger. As in a thaw, mobilization means movement and is a progression from the freezing function of the dorsal vagal circuit. The sympathetic nervous system prepares our body for action. Faced with danger this is in the form of fight/flight.

Accurate neuroception detects a threat from which there is a possibility of escape, as in my experience on the beach. Where neuroception is over-active, as is often the case with traumatized children, danger may be perceived where there is none, or the level of it is exaggerated. So, the child over-reacts, and fights or takes flight when there is no actual need. This can happen very quickly from a state of apparent calm and is often bewildering to those involved.  However, we might all recognize our own ‘trigger’ points, which can lead to defensive over-reactions. (pic, Anxiety Canada, 2019)

Thinking of this in relation to running away, there may be different things going on. The child who runs away maybe in a fearful state and has sensed a threat, whether it exists or not. The aim is to escape. Another child in the same situation, may perceive the threat to be even more serious, and he or she may freeze rather than flee. The dorsal vagal circuit for this child may be dominant and the first form of defence.

For anyone working with this, such as a carer, the fleeing child may evoke more anxiety than the freezing child, though the fleeing child may be healthier and less traumatized. This reminds me of Winnicott’s (1956, 1967) concept of the antisocial tendency and delinquency as a sign of hope. The fighting/fleeing child is at least ‘alive’ and mobile. The nuisance caused by the child also contains hope, which provides an opportunity for us to respond and nourish.  Children who have suffered inescapable terrifying abuse, often feel that their bodies are useless and a source of shame. It seems a natural and healthy consequence in the process of recovery that the ability to escape might be put to the test. Feeling that this is now possible can be seen as a hopeful development.
Clearly, we don’t want traumatized children running away just to prove that they can. There is also always the possibility that the situation is not so benign and something real is causing fear. We always need to be vigilantly aware of any possibility of abuse or potential harm. Establishing and preserving safety is always the number one priority.  We should make sure that the environments we provide for children are nurturing and emotionally containing.

We can also help the young person gain a sense of physical mastery in many other ways. For example, playing sports, bike riding, running, skipping, music and dancing. Games such as tag and, hide and seek, which allow a feeling of being able to escape might also provide an excellent way of fostering a newfound sense of belief in a competent body. We can see that as Porges says, the mobilization of the sympathetic nervous system, can be playful and not just fight/flight.  Simon Bain (2012), a resident of the Cotswold Community in the 1970s, seems to suggest this when he talks of his memories of running away, 
Although, you could say, I wasn’t a success - the funniest and indeed my fondest memories are the ‘running outs’ we used to do, with the staff spending half the night chasing us. 
Porges (2017, p.129) explains, 
The difference between the fight/flight and play is that while mobilizing, we’re making eye contact and engaging each other. We’re diffusing the cues of threat with social cues, so we can utilize the sympathetic nervous system to support movement without moving into defensive fight/flight behaviors. When we involve the social engagement system, we can even use the oldest system, which is immobilization, and we can be in the arms of someone that we feel safe with.
The final and most recently evolved part of the autonomic nervous system is the ventral circuit. As with the dorsal vagus this is part of the parasympathetic nervous system.  It evolved 200 million years ago and is uniquely mammalian. The ventral circuit looks for safety and social connection. In this sense it could be considered as a preventative and anticipatory part of the nervous system. It gives us the capacity to co-regulate (Dana, 2018). The neuroception involved is picking up cues for connections that will add to our safety and hence improve our potential for survival. Unfortunately for many traumatized children this function of the nervous system is shut down and underdeveloped. 

Conditions of safety and repeated positive experiences are essential for it to develop and come into use. This will happen as the dorsal vagus and sympathetic circuits are less active. As freeze, fight/flight are reduced, moments of calm are increasingly possible. Connection is a hugely protective factor that promotes further development. Once connections are established potential threats are reduced. As Porges (2017, p.43) explains this important aspect of polyvagal theory, 

"Moreover, and perhaps most important, the theory explains how safety is not the removal of threat and that feeling safe is dependent on unique cues in the environment and our relationships that have an active inhibition on defense circuits and promote health and feelings of love and trust (e.g., Porges, 1998)."
Once protective connections are established, these can be used to anticipate and prevent the activation of the dorsal vagal and sympathetic circuits. Once this begins the individual is more in the connecting and less in the defensive state. This begins a positive spiral where the person is on the road to recovery. Acting out, such as running away are now less likely.

I have outlined how the three parts of the autonomic nervous system may be activated and their use in promoting our safety, survival and well-being. Understanding the different functions is vital to effective treatment. For example, the sympathetic circuit of fight/flight, whilst being more difficult to manage may mean the child is in a healthier state than if he/she was freezing and immobile.

Using running away as an example, not running may be at both ends of the spectrum of frozen and connected. Stillness can be due to calm safety or fear. The difference between the two can be sensed by our neuroception – how we unconsciously read and are attuned to what is happening. The difficult job of responding to running away behavior offers the potential bridge between the dorsal vagal and ventral circuits.  The fight/flight and playful mobilization of the sympathetic nervous system, however challenging may also contain the hope that Winnicott referred to over fifty years ago.

As Porges (2017, p.56) states, 
I want to emphasize that understanding the response, not the traumatic event, is critical to the successful treatment of trauma.
