Heymans' temperamental dimensions in personality research

In this article an overview is given of personality research related to the temperamental system of the Dutch philosopher and psychologist Gerard Heymans (1852–1930). After a sketch of this three-dimensional typology, three domains of research are briefly described. The first is a line of research on the system itself and its applications in differential psychology. In the second, the role of its dimensions in modern trait psychology is sketched. In the third line of thought the Heymans categories are viewed and investigated as dimensions of person perception.
