The Author questions the possibility of analytically investigating the psychotherapeutic process in relation to the sole variable of Attachment, within a nonlinear dynamic system. The study analyses the effect of traumatic anxiety and dissociation: these are registered – that is, coded, according to the multiple communication styles with the caregiver, by Langs’s hypothesis, and modulated by the multiple internal working models according to the Attachment theory. The function of the psyche-soma, a structure identified by Winnicott, is related to the center of the internal working models. Because of a morphological configuration of the information, the structure would act topologically, trying to safeguard a stable form within the area of traumatic chaos: the rarity of the initial conditions, that is the unlikeliness of an event (comparable to a traumatic event), produces structures of greater complexity in relation to the recipient’s need for a message whose form is stable. This might suggest that there is a possibility to overcome the dissociation induced by the trauma, by “playfully” using metaphors, models, and proto-symbolic images produced by the patient and having a remarkable therapeutic potential during therapy.
