Big-T, Little-t, and Neglect

Not all trauma looks the same. The field distinguishes between different types — not to rank suffering, but because the type of trauma shapes the pattern of symptoms and the approach to treatment.

Big-T Trauma

The events most people think of when they hear “trauma” — assault, accidents, disasters, combat, witnessing death. These are single-incident or acute traumas that overwhelm the system in an obvious, identifiable way.

Little-t Trauma

Less dramatic, but no less impactful. Chronic criticism. Emotional unavailability. Being repeatedly shamed, dismissed, or compared unfavourably. Bullying. A parent who raged unpredictably. Growing up in a household where nothing felt safe or predictable.

These experiences are “small” individually. Accumulated, they shape the nervous system profoundly — often more than a single Big-T event, because they happened repeatedly during development, when the brain was being built.

Research consistently shows that cumulative “little t” stress predicts PTSD and complex trauma symptoms at least as reliably as single-incident trauma. The nervous system does not distinguish between sources of overwhelm — only between whether it was processed or not.

Neglect — The Absent Experience

Perhaps the most underrecognised form of trauma: not what happened, but what should have happened and did not.

A child needs consistent attunement, soothing, being seen and responded to. When those experiences are chronically absent — when the caregiver is present but not really there, or unavailable, or too consumed by their own distress — the developing nervous system learns: I am alone with this. I cannot rely on others. Something is wrong with me.

These conclusions feel like personality. They are not. They are adaptations — and they can be updated.

The voice that says “my childhood wasn’t that bad”

This is one of the most common obstacles in trauma work. When there is no single dramatic event to point to, it can feel illegitimate to call your experience “trauma.” But the nervous system does not require a diagnosis-worthy event to be shaped by experience. If what you experienced left patterns you are still living with — that is enough.
