Traumatic experiences, particularly those in early life, give rise to psychological ("internal") conflict. The greater part of mental activity is unconscious: conscious mind is protected from the experience of this conflict by inbuilt defences, designed to decrease 'unpleasure' and to diminish anxiety. These defences are developmentally appropriate but continuation into adult life results in either psychological symptoms or in a diminished ability for personal growth and fulfilment. Psychological conflict can be examined with regard to the anxiety itself, the defence, and the underlying wish or memory. The individual's previous family and personal relationships will have symbolic meaning and be charged with powerful emotions. Representations of these relationships will emerge during therapy and provide a route towards understanding and change.
