In the history of psychology there have been many different fields of interest. Human development, in particular, has been an interesting field of study for many psychologists. Freud, Erikson, and Piaget are all great theorists with similar, but different, ideas about human development. Their theories of human development predicted that humans go through different stages as they age. Although the three theorists have common relationships in that they developed their ideas and theoretical stages for human development over the lifespan, each theory represents its own uniqueness as to what these stages were and what they focus on and where they also connect human development .

According to Freud, he believed that human development is fueled by internal forces (Essay UK, 2014). He believed that our sexual being was the most powerful of all internal forces during human development. That said, Freud linked everything to sex. Therefore, nowadays, Freud's theory of human development is labeled as stages of psychosexual development. According to Berger, the author of The Developing Person Through the Life Span, Freud believed that “human beings go through different stages in their lives based on which part of their body gave them sexual gratification (Berger, 2014).” Erikson developed his theory inspired by Freud. Not only did Erickson focus on child development, but he also added stages for adulthood. He focused on identity rather than sexuality, unlike Freud. Later now, Erikson's theory is known as the psychosocial stages of development. It is also known for its eight stages of life; trust versus mistrust, autonomy versus shame and doubt, initiative versus guilt, industry versus inferiority, identity versus identity confusion, intimacy versus isolation, generativity versus stagnation, and integrity versus desperation (Berger, 2014).

Its phases are recognized as cognitive phases. These stages are based on what the child can do. That said, Piaget's theory focuses on the child's learning and development. According to Piaget, a child goes through four stages while growing up. Although both Piaget and Freud were interested in the child's abilities and senses, Piaget did not relate the stages to sexual desires unlike Freud. Piaget believes in four developmental phases known as the sensorimotor phase, preoperational phase, concrete operational phase, and formal operational phase (Berger, 2014). These three theories of human development each have their own positive points and their own frauds. In other words, each of these theories has some value because they are not entirely wrong, but they are also known to receive some criticism since the theory is not a science, so it cannot be applied to some cases. To conclude, although each of Freud, Erickson, and Piaget's theories are similar in their calendar and sequence of life events, they differ in their focuses. Freud focuses on sex, Erikson focuses on social ability, and Piaget focuses on the child's cognition and senses. Works Cited Berger, K. S. (2014). The developing person across the lifespan.
