Fear Extinction

« Back to Glossary Index

Fear extinction is the process by which a learned fear response gradually weakens when the feared cue is repeatedly experienced without harm. It doesn’t erase the original fear memory, but builds a new “safety memory” that can inhibit the fear response under the right conditions. Fear extinction happens when something that once triggered alarm — an elevated heartrate, crowded room, difficult conversation — is encountered without the expected negative outcome. Over time, the nervous system recalibrates: what once signaled danger begins to feel tolerable, even neutral. In clinical settings, fear extinction is the basis for exposure-based therapies. By helping a person approach rather than avoid what they fear — gradually, predictably, and with support — the brain has repeated opportunities to learn: this is not as dangerous as it once seemed.
