hydraulic model

any physiological or psychological model based on the analogy of fluid flowing through a system under pressure, such that pressure may build up in the system and seek release. Sigmund Freud’s model of the libido as an energy that can build pressure and seek release (catharsis) is a notable example. A more literal use of the hydraulic model was the erroneous concept of the nervous system introduced in the early 17th century by René Descartes, who believed that nerves were tubes through which animal spirits flowed from the brain to the muscles. According to this model, habits were formed when repeated use of the nerve tubes caused them to become distended and blocked.
