Piaget, Erikson, and Kohlberg have contributed many years studying the human developmental milestones as they each see it. Through their own tests and research they have provided answers to the moral, lifespan, brain and nervous system development. The depth that they explored, children as well as adults, has helped many through their journey of life. Psychologists have provided us with the many answers to the why and how children go through their stages of life. The three men: Piaget, Kohlberg, and Erikson, we will look ...view middle of the document...
Throughout the course of the last two decades, scores of undergraduate psychology students have been introduced to the work of Lawrence Kohlberg in their Introductory Psychology courses and Lifespan Development courses. His research, and the research of several of his contemporaries and colleagues, such as Carol Gilligan, was the first of its kind to foster a contemporary understanding of how individuals develop as moral beings. Whether or not we have had the opportunity to learn about Kohlberg’s work, most of us have asked ourselves those fundamental questions about the ways we make decisions, particularly those decisions that cannot be linked to the reduction of a primary drive, or those decisions that do not reward us with a tangible, easily recognizable reward. As human beings living in societies, many of us have struggled with the ways decisions and policies are implemented in our justice system. Kohlberg’s work aids both our understanding of the ways in which individuals make moral decisions, and demands that we use a more discerning system to critique the systems of justice that are in place in our societies. Kohlberg is known more for the older child. He calls Stage 1thinking “preconvention” because children do not yet speak as members of society. Instead, they see morality as something external to themselves, as that which the big people say they must do. Stage 2-Individualism and Exchange- At this stage, children recognize that there is not just one right view that is handed down by the authorities. Kohlberg has gone into more depth into the teenagers life and older then Piaget.
Erik Erikson has made a contribution to the field of psychology with his developmental theory. He can be compared to Sigmund Freud in that he claimed that humans develop in stages. Erikson developed eight psychosocial stages in which humans develop through throughout their entire life span. Erikson believed that development is primarily qualitative because changes are stage like, but also quantitative as one's identity becomes stronger and one's convictions solidify. He believed that nature determines the sequence of the stages and sets the limits within which nurture operates. However, all must pass through one stage before entering the next in the stated order. Birth to 1 year, 1 to 3 years, 3 to 5 years, 6 to 12 years,...
