There are many changes that take place in human life. A human being starts as an infant, develops into an adult and later becomes elderly. The branch of psychology concerned with all these changes that occur over the course of our lives is known as developmental psychology. At first it catered for infants and children but currently it includes the changes that occur in the entire life of an individual.
In development psychology the topics covered revolve around motor skills and psycho-physiological processes. This is because as life continues, an individual is likely to face new things and should be able to move on with life without problems. For instance, cognitive development includes areas like problem solving, moral understanding and conceptual understanding.
In our lives in early stages we are expected to learn our first language, get along easily with people as we grow up and cope well. Developmental psychology entails information about language acquisition, our social attachments, our emotional responses to various situations and personality. In some cases there are children who have self conception and identity issues but cognitive development provides ways of dealing with such problems at early stages of life. This helps to build the individual’s esteem.
Changes in life are a must and a human being has to evolve through various stages of life in his life span. This shows that development knowledge is vital and is applied in fields like educational psychology, child psychopathology and forensic developmental psychology. This knowledge is also used to complement basic researches in other fields like social, cognitive, comparative and ecological. For more information on development you can browse on the Internet.
