External inhibition is a classical conditioning phenomenon in which a strong or unfamiliar stimulus, presented just before or during a conditioned stimulus, causes a temporary reduction in the conditioned response that the conditioned stimulus would normally produce. The effect illustrates that a conditioned response is not fixed but can be disrupted by unrelated environmental interference at the moment it would otherwise occur.

External inhibition is the observed decrease of the response of a conditioned reaction when an external (distracting) stimulus that was not part of the original conditioned response set is introduced. This effect was first observed in Ivan Pavlov's classical conditioning studies where the dogs would salivate less (conditioned response) when presented with the sound of the tuning fork (conditioned stimulus) in the distracting context of a passing truck (external stimulus).
