vacuum activity

in classical ethology, the occurrence of a fixed action pattern in the absence of the usual external stimulus (the releaser, or sign stimulus) that triggers the pattern. This is believed to be caused by a build-up of action-specific or motivational energy that overrides the innate releasing mechanism. Also called vacuum response. [proposed by Konrad Lorenz]
