If a same sex parent is absent during the phallic stage (when the superego is developing), the child cannot internalise that person's moral code/attitudes as there is no opportunity for identification
The consequence is that the person has little control over anti-social behaviour and is dominated by their instinctual id impulses
Normal identification with the same sex parent during the phallic stage (when the superego is developing) means that the child takes on the same moral code/attitudes as that parent
The consequence is that if the parent's behaviour is deviant, the small child adopts similar deviant behaviours and morals
Due to significant deprivation of maternal love during the critical period of attachment formation, leading to a negative internal working model for future relationships and a negative understanding of the world
