2 Opposite Ways The Child Responds To Stress : Hyperarousal And Dissociation

hyperarousal and dissociation in children

When, as children, we are subjected to trauma, stress, fear and even terror, our nervous systems may respond in two, diametrically, opposed ways. Both these responses, however, have evolved to serve the same purposes : THOSE OF SELF – PROTECTION AND SELF – PRESERVATION.

Both, too, involve biochemical changes in the brain (in particular the regions of the AMYGDALA, the HYPOTHALAMUS and the BRAIN STEM) and physiological changes in the body that, in turn, alter how we think, feel and behave (or, to put it in more psychological terms, they affect us on a cognitive, emotional and behavioural level).

To what degree the child responds to stress will depend upon the severity of the stress and its duration – the more severe and long-lasting, the more extreme the child’s hyperaroused or dissociatiated reaction is likely to be.

The psychological researcher, Sperry, has put forward an ascending scale showing different symptoms of HYPERAROUSAL and DISSOCIATION. I represent this scale below :

SYMPTOMS OF DISSOCIATION IN ASCENDING ORDER OF INTENSITY :

  • a sense of detachment
  • a sense of being numb (shut down of feelings/emotions)
  • compliance
  • lowering of rate of heart beat
  • distorted perception of time  (time may be perceived as ‘standing still).
  • a sense of being ‘detached from reality’ (the psychological term for this is ‘derealization’)
  • transient, discrete and ephemeral periods of psychosis (Sperry uses the term ‘mini-psychoses’)
  • fainting

SYMPTOMS OF HYPERAROUSAL IN ASCENDING ORDER OF INTENSITY :

  • constant feelings of being under threat and continuously being on the lookout for threats (unconsciously and consciously) ; the psychological term for this is hypervigilence
  • anxiety
  • reactivity
  • alarm
  • speeding up of heart beat, increased blood pressure, shallower / increased rate of breathing (the psychological term for this is hyperventilation), increase in amount of glucose released into blood stream and consequently delivered to the muscles (collectively, this group of physiological responses is frequently referred to as the fight/flight response).
  • fear
  • panic
  • terror

Significant stress giving rise to neurological changes that is repeated throughout childhood can, sadly, lead to long-term damage being done to the brain’s physical development (which can be learned about by clicking here).

hyperarousal and dissociation in children

 

Dissociation can be seen as avoidance strategy (although the ‘strategy’ forms automatically and on an unconscious level), involving a withdrawal from the ‘real world’ (as this ‘real world’ generates intolerable mental pain) into an ‘inner world’ (perhaps a ‘fantasy world’ of considerable complexity in which the child makes-believe s/he is ‘all-powerful’ or in which s/he is completely protected and safe : the short – term gains for the child, won by withdrawing into such a phantastical place of psychological refuge, hardly necessitates further elucidation.

During a period of significant trauma the child may (unconsciously) adopt one or both forms of psychological protection. In the case of the latter, when the biological and emotional demands of the hyperaroused response cease to be sustainable, s/he may switch to the dissociatiated form of self-protection (again, this entire process is unconsciously orchestrated).
