Social and emotional development refers to a child's ability to form relationships and manage emotions. There are several theories that describe socio-emotional development. Freud's psychodynamic theory views development as occurring through the id, ego, and superego. Erikson's psychosocial theory proposes 8 stages of development centered around psychosocial crises. Bandura's social learning theory emphasizes how children learn behaviors through observation and modeling influential individuals like parents and teachers. The core focus of socio-emotional development is a child's capacity to establish and maintain relationships with others.
