This book is written primarily for psychotherapists and other practitioners; it describes a new and effective form of dynamic therapy designed for working with adults and with adolescents. The theory, on which the new form of therapy is based, is centred in a paradigm that extends and crucially alters the paradigm for developmental psychology opened by the Bowlby/Ainsworth attachment theory. It describes a pre-programmed process, the dynamics sustaining attachment and interest sharing, which is activated as soon as people perceive that they are in danger. This process is made up of seven pre-programmed systems which interact with one another as an integrated whole. They include Bowlby's two complementary goal-corrected behavioural systems: attachment (also referred to as careseeking) and caregiving. Whenever the process is able to function effectively, it enables people to adapt more constructively and co-operatively to changing circumstances.
