Definition
Attention narrowing is the constriction of awareness under threat — focus locks on the danger while peripheral perception, memory encoding, and cognition are reduced. It is one of the most common forms of transient dissociation.
Why it matters
Explaining attention narrowing helps trauma survivors understand why their memory of an event may be fragmented or partial.
The Science
Under high sympathetic activation, sensory integration and hippocampal encoding are compromised. Memory of traumatic events often reflects this narrowing.
The NSI Perspective
NSI treats attention narrowing as adaptive under threat, and unproblematic when it fully resolves after the threat passes.
Clinical Implications
Fragmented memory of trauma is expected biology, not evidence of unreliability.
Practical Application
If you remember some vivid details and none of the rest, that is how nervous systems remember threat.
