特征为兴趣集中于内心过程的一种典型态度。

A turn from reality to phantasy. Freud borrowed this term from C. G. Jung and defined it this way: "introversion denotes the turning away of the libido from the possibilities of real satisfaction and the hypercathexis of phantasies which have hitherto been tolerated as innocent" (Introductory Lectures 16.374). For Freud, an example of such introversion is art, since the artist turns away from real satisfaction to the life of phantasy.
