Comparing Piaget's Psychosocial And Cognitive Development

There are many early theorists that have influenced the field of psychology and mental health. Two of who are Erik Erikson and Jean Piaget. Their Psychosocial and Cognitive Development Theories outline development stages and the differences and similarities of these are outlined below (Varcarolis, E., Halter, M., 2013).
Erik Erikson was a child psychoanalyst who explained development as happening in eight life stages. His psychosocial theory dealt with eight stages throughout the life of a person. New problems depict each stage and the outcome is determined by how each person deals with each problem (Varcarolis, E., Halter, M., 2013). The stages are: Trust vs Mistrust: this stage occurs below the age of one. In this stage, theory states that
Conservation is possible in this stage. They can order objects in patterns, and are able to see things from other points of view (Varcarolis, E., Halter, M., 2013). Formal operational stage: eleven years to adulthood. Puberty and conceptual reasoning arise during this stage and the child’s problem solving and ability to think abstractly starts to reflect those of an adult (Varcarolis, E., Halter, M., 2013). Piaget’s stages differ from Erikson’s in that Erikson’s stages came from experience rather than research and observation like Piagets. Another major difference between them is that not all of Piaget’s stages will be gone through throughout adulthood; we as people influence our lives. Erikson posits that a person will go through all stages, as it is essential in the development process (Varcarolis, E., Halter, M., 2013). Both of their theories outline phases one goes through throughout their lives. Each states that each phase will bring about different challenges, which will lead to failure or accomplishment in the next stage. They also believe that people get inspiration from their environments and will lead to intellect and maybe inspire a person to want to be successful (Varcarolis, E., Halter, M.,
