Usage notes
The use of this word for the study of pleasure and pain was originally coined by Henry Rutgers Marshall in the late 19th century. It has fallen into disuse in modern psychology and neurology, except when referring to the historic work of Marshall and his colleagues. However, modern research into the neurology of pleasure and pain has led to the use of the term in management theory.
