Who was introspection used by?

The term was first used by the psychologist William James in The Principles of Psychology (1890). As the psychological novel developed in the 20th century, some writers attempted to capture the total flow of their characters' consciousness, rather than limit themselves to rational thoughts.

Which psychologist would use introspection?
