Child psychology is one of the many branches of psychology and one of the most frequently studied specialty areas. This particular branch focuses on the mind and behavior of children from prenatal development through adolescence. Child psychology deals not only with how children grow physically, but with their mental, emotional and social development as well.
The Different Contexts of Child Psychology
When you think of development, what comes to mind? If you are like most people, you probably think about the internal factors that influence how a child grows, such as genetics and personal characteristics. However, development involves much more than the influences that arise from within an individual. Environmental factors such as social relationships and the culture in which we live also play essential roles.
