Triggers
A cue (sight, sound, smell, phrase, tone, situation) linked to past harm that sets off a reaction belonging to the original event rather than the present.
What drives it
The threat system generalises from the original danger to anything that resembles it; reacting fast protected the person once and now fires at harmless lookalikes.
How it shows
Work
A specific phrase ('Can I have a word?') or tone produces a sudden shift: going pale, rushing to defend, shutting down. The reaction is consistent and specific, and puzzling to others because the situation seems ordinary.
Relationships
A partner's sigh or the sound of keys sets off an argument that seems to come from nowhere; the reaction fits a past relationship or parent more than the present person.
Self
A sudden jump in feeling that you can trace to a cue in the room and that feels older than the present moment.
What tells it apart
Anger as a secondary emotion: Trigger reactions are cue-bound and repeat with the same cue; secondary anger can arise in any situation that hurts or frightens.
Rejection sensitivity: Rejection sensitivity is a general readiness to perceive rejection; a trigger is tied to particular cues from a particular past experience.
Amygdala hijack: 'Hijack' names any fast overreaction; a trigger points to a specific, identifiable cue and a past source.
A test
Track when the outsized reactions occur; if they cluster around specific, nameable cues and feel older than the present, it may be a trigger.
Questions to carry
- Where do the outsized reactions cluster, and which specific sound, phrase or tone sets them off?
- Which small cue sends me somewhere older than the room I’m standing in?
How strong the research is
moderate. Cue reactivity in PTSD is well documented; popular use stretches 'triggered' to any discomfort, and research finds trigger warnings do not reduce distress.
Where it comes from
Ivan Pavlov, 1890s to 1900s (conditioning); O. Hobart Mowrer, 1947 (two-factor theory); DSM-III, 1980 (cue-induced distress); popular use from the 2010s
