Object Relations Theory: the idea that the ego-self exists only in relation to other objects, which may be external or internal. The internal objects are internalized versions of external objects, primarily formed from early interactions with the parents. There are three fundamental "affects" that can exist between the self and the other - attachment, frustration, and rejection. These affects are universal emotional states that are major building blocks of the personality.
In psychology, sublimation is a mature type of defense mechanism where socially unacceptable impulses or idealizations are consciously transformed into socially acceptable actions or behavior, possibly resulting in a long-term conversion of the initial impulse.
