The phenomenology of trauma is a historical, epistemological, and methodic inquiry that wishes to test the validity of an already settled dynamic model of surprise as shock-rupture based on its correlated inner structures of attention and emotion. Thanks to an integrative approach, crossing phenomenological subjective experiences and empirical data, we hope to renew the understanding of the blank lived experience of trauma and the passive preconscious dynamics of traumatism, as well as to generate possible therapeutic effects.
