Object–Dyad:

The object-dyad is an internalized representation of a highly emotional, self–object (self–other) interaction, typically between an infant and early caregiver. Three core components are an internal image of oneself, an internal image of the other, and the emotional connection (love, anger, frustration) linking them. In healthy development, according to object relations theory, these initial, often polarized, dyads form the fundamental building blocks of personality and relationships. Mature development integrates polarized images into a more whole and stable view of the self and others. Object-dyad components:

• Self-representation: Internal, psychic image of self within a specific interaction. 
• Object-representation: Internal image of the other significant person. 
• Affect-laden interaction: Intense, emotional experience linking self and object in that interaction
