The author contends that, following Freud, trauma may be viewed as a disruption of the ego's ‘protective shield’ and that a central factor of this shield is an internalized relationship to a thinking-containing mother. Severe trauma destroy this inner connection, resulting in the reversal of α-function and the establishment of a rigid traumatic organization (β-screen) that brings coherence to the shattered psyche. However, this is an ‘organized chaos’ in which concrete forms of thinking predominate. The patient's ability to think, dream and imagine is significantly curtailed and she is consequently locked in a traumatic world from which she is unable to evolve. He offers a detailed case history to illustrate these points and the vital role the analyst's imaginative capacities play in the analysis of such individuals. Finally, he addresses the development of the capacity to represent the trauma, starting with primitive, often somatically encoded experiences, and evolving toward the capacity for historicization.
