The Electra complex was theorized to explain how girls develop a moral conscience

The Electra complex, introduced by Sigmund Freud in 1913, suggests that a young girl's psychological development is shaped by an unconscious desire for her father and a subsequent rivalry with her mother. According to this theory, the conflict is typically resolved around age six when the child begins to identify with the mother, thereby internalizing social norms and developing a 'superego' or moral conscience.
