neural network known as the innate releasing mechanism in response to an external sensory stimulus known as a sign stimulus or releaser. A mating dance may be used as an example. Many species of birds engage in a specific
series of elaborate movements, usually by a brightly colored male. How well they perform the "dance" is then used by females of the species to judge their fitness as a potential mate.
The key stimulus is typically the presence of the female. Although fixed action patterns are most common in animals with
simpler cognitive capabilities, humans also demonstrate fixed action patterns. For example, infants grasp strongly with their hands as a response to tactile stimulus" Reference Wikipedia.org back to 206)
