phrenology (redirected from phrenologic)

phrenology, study of the shape of the human skull in order to draw conclusions about particular character traits and mental faculties. The theory was developed about 1800 by the German physiologist Franz Joseph Gall and popularized in the United States by Orson Fowler and Lorenzo Fowler through their publication the Phrenological Almanac and other publications. Modern neurology and physical anthropology have refuted the theory and consider its use a form of quackery.

phrenology

Study of the shape of the skull as an indication of mental abilities and character traits. Franz Joseph Gall stated the principle that each of the innate mental faculties is based in a specific brain region (“organ”), whose size reflects the faculty's prominence in a person and is reflected by the skull's surface. He examined the skulls of persons with particular traits (including “criminal” traits) for a feature he could identify with it. His followers Johann Kaspar Spurzheim (1776–1832) and George Combe (1788–1858) divided the scalp into areas they labeled with traits such as combativeness, cautiousness, and form perception. Though popular well into the 20th century, phrenology has been wholly discredited.
