Erik Erikson viewed development as a series of conflicts affected by social and cultural factors. Each conflict must be resolved for the child to progress emotionally, with unsuccessful resolution leaving the child emotionally disabled. Sigmund Freud proposed a psychosexual theory of development. He proposed that certain parts of the body assume psychological significance as foci of sexual energy. The foci shift as the individual moves through the different stages (oral, anal, phallic, latency, and genital) of development.
Lawrence Kohlberg described moral development as having three levels (preconventional, conventional, and postconventional). His theory closely parallels Piaget's. Jean Piaget's cognitive theory interprets how children learn and think and how this thinking progresses and differs from adult thinking. Stages of his theory include sensorimotor, preoperations, concrete operations, and formal operations.
