According to Klein, the child’s relation to the breast is fundamental and serves as a prototype for later relations to whole objects, such as mother and father.
The very early tendency of infants to relate to partial objects gives their experiences an unrealistic or fantasy-like quality that affects all later interpersonal relations.
Klein’s ideas tend to shift the focus of psychoanalytic theory from organically based stages of development to the role of early fantasy in the formation of interpersonal relationships.
Melanie Klein was born on March 30, 1882, in Vienna, Austria, as the youngest of four children born to Dr. Moriz Reizes and his second wife, Libussa Deutsch Reizes.
Her father, a struggling physician, ended up as a dental assistant, while her mother, despite her fear of snakes, ran a shop selling plants and reptiles.
Klein felt neglected by her elderly father, whom she saw as cold and distant, and although she loved and idolized her mother, she felt suffocated by her.
In mourning, Klein married Arthur Klein, a close friend of Emmanuel, and later regretted that this marriage at age 21 hindered her dream of becoming a physician.
Projection is a defense mechanism used by infants to remove both good and bad objects, imagining their feelings and impulses as external entities, to alleviate anxiety about internal forces causing destruction.
Klein (1955) suggested that, from very early infancy, children adopt several psychic defense mechanisms to protect their ego against the anxiety aroused by their own destructive fantasies.
Introjected objects are children's fantasies, often depicting their mother as constantly present within their body, despite the fact that the real mother is not always present.
Introjection, one of Klein's concepts, suggests that infants fantasize about incorporating their experiences with external objects, such as the mother's breast, into their bodies.
Infants' biological predisposition to value nourishment and life instincts leads to ambivalent feelings towards a single person, a concept similar to transference feelings experienced by therapy patients, as they do not use language to identify good and bad breasts.
Depressive children understand their mother as both loved and hated, remorse past destructive actions, and feel empathy for her, enhancing their future interpersonal relationships and fostering better relationships.
Adults adopt the paranoid-schizoid position in a primitive, unconscious way, experiencing themselves as passive objects or projecting their unconscious paranoid feelings onto others to avoid destruction or to view themselves as empty or worthless.
Projection allows people to attribute their subjective opinions to others, allowing them to believe their own feelings are true, as seen in infants and adults who attribute their goodness to nurturing breasts.
Under pressure of ambivalence, conflict and guilt, the patient often splits the figure of the analyst, then the analyst may at certain moments be loved, at other moments hated.
Klein's theory suggests that children can have both homosexual and heterosexual relationships with both parents, with girls and boys experiencing the Oedipus complex differently.
To foster negative transference and aggressive fantasies, Klein provided each child with various toys and substituted play therapy for Freudian dream analysis and free association.
A study at York University found that abuse survivors with malevolent and less emotionally invested relationships were correlated with greater symptoms of PTSD and lower self-esteem.
