Dimension 05 of 15
Developmental — When It Happened
How age at wounding shapes the architecture of injury
The developmental dimension tracks not just what happened but when it happened — because the timing of relational disruption determines which neurological systems were being built at the moment of injury, and therefore which functions are most affected. An attachment disruption in the first 18 months affects the subcortical stress-response systems and implicit memory. A disruption at 3-5 years affects the identity formation systems. A disruption in adolescence affects the prefrontal-limbic integration that governs emotional regulation in adult relationships.
The wound pattern
The developmental wound is the gap between what the environment provided and what the developing nervous system required at a specific phase. That gap gets filled by the adaptive self — the personality that formed around the wound. Understanding the developmental timeline helps locate the wound with precision: what is intact (was in place before the disruption) versus what is fragile (was being formed when the disruption occurred).
The healing path
Developmental healing follows the principle of meeting the person where they are developmentally, not where they are chronologically. Dan Siegel's 'name it to tame it' approach targets the cortical-limbic integration that trauma disrupted. Janina Fisher's trauma-informed stabilization treatment phases healing through somatic grounding, parts work, and finally narrative integration — in that sequence, never the reverse.
