Psychological evaluation
Modern "Psychological evaluation" has been around for roughly 200 years, with roots that stem as far back as 2200 B.C. It started in China, and many psychologists throughout Europe worked to develop methods of testing into the 1900s. The first tests focused on aptitude. Eventually scientists tried to gauge mental processes in patients with brain damage, then children with special needs.
Psychology
The world federation of national psychological societies is the International Union of Psychological Science (IUPsyS), founded in 1951 under the auspices of UNESCO, the United Nations cultural and scientific authority. Psychology departments have since proliferated around the world, based primarily on the Euro-American model. Since 1966, the Union has published the "International Journal of Psychology". IAAP and IUPsyS agreed in 1976 each to hold a congress every four years, on a staggered basis.
