Freud's theory argues, that the morals that stem from our parents will be passed down generations not because it is what they concluded but because it is our genetic makeup to believe what our parents believe and what we are surrounded by as children. Freud's peer, Jean Piaget, also identified unconscious development. While Freud was interested in emotional and sexual development, Piaget focused on intellectual development that children can only process new concepts at a particular stage in their development (Linda Pound p.37). One of Piaget theories was the theory of Moral Development in which he explains that he sees development as progressing through two broad phases that overlap, so sometimes a child's moral reasoning will be in the heteronomous phase and at other times it will be an autonomous phase. The Heteronomous phase is when children understand that there is only one way of seeing and doing things. The Autonomous phase is when children understand that people have different views and values on circumstances. (......) Lev Vygotsky (date) also believed that children are unconsciously influenced by what they absorb in their early years. His theory of 'Social and Cognitive Development' was that children mimic the adults that surround them, he emphasizes that "children's language was social in origin because it arose in the interaction between child and others". In other words, the child's language both results from and is part of social interaction. While Piaget and Freud believe that knowledge and understanding come from personal experiences, Vygotsky emphasized the importance families, communities and the involvement with other children.
