Developmental psychology is characterized as a branch that aims to study the interaction of physical and psychological processes and the stages of growth, from conception to the end of a subject's life.

Development is a continuous process that begins from conception, and continues after fertilization of the egg, running from the cell subdivision until millions of cells are formed. As the cells assume specialized functions, the formation of the systems that provide the basis for the physical part of development begins. However, physical, cognitive, social, affective development continues throughout all stages of a subject's life and ends with death.

Thus, the phenomenon of development, articulates and interfaces with various areas of knowledge such as: education, biology, sociology, anthropology, medicine, among others, interacting with different types of knowledge in order to encourage their explanations.

Developmental psychology brings an understanding of the psychological changes that occur over time, with the help of some theories and theorists, as well as Jean Piaget, these models aim to explain how changes occur in the subject's life and how they can be understood and described.

Traditionally, the first studies referring to developmental psychology mentioned only the development of children and adolescents. However, this focus has changed over the years, and today, there is an idea that the study on human development should cover the entire life cycle process.
