Avoidance learning

Learning actions that prevent or escape an anticipated aversive outcome. In anxiety, immediate relief and the absence of disconfirming experience can maintain avoidance even when the feared prediction is inaccurate.

An action reducing contact with an anticipated aversive situation or experience. It can provide immediate relief while limiting corrective learning, but avoidance of genuine danger is not thereby pathological.

A precaution intended to prevent a feared outcome or conceal anxiety. It can maintain fear when safety is attributed to the precaution, when it blocks informative experience, or when it produces misleading symptoms. Whether a behavior has this function depends on context; objectively useful precautions are not inherently pathological.

Use of a precaution in a way intended to support engagement while preserving useful learning. Its value cannot be settled from its label; prediction testing, attribution of safety, replacement precautions and longer-term transfer should be measured. An undergraduate contamination experiment showed why reduction in symptoms need not be logically impossible in the presence of a safety behavior.^[ref]

Seeking another person's confirmation of safety or certainty. In an anxiety-maintaining cycle, immediate relief can reinforce repeated requests without changing the underlying interpretation. This function should be distinguished from appropriate information seeking or clinical assessment.
