idiographic

adj. Of or relating to psychological approaches in which the individual is the unit of analysis as opposed to understanding people in general, which is called a nomothetic approach. This approach is embodied in the theories of Gordon Allport, who differentiated between individual dispositions and common traits, and the work of Henry Murray, who described the study of individuals as personology. Idiographic psychology focuses on the uniqueness of the individual, as opposed to the characteristics shared by some other people or all other people. Also spelled ideographic.
