Childhood

Childhood is the age span ranging from birth to adolescence. According to Piaget's theory of cognitive development, childhood consists of two stages: preoperational stage and concrete operational stage. In developmental psychology, childhood is divided up into the developmental stages of toddlerhood (learning to walk), early childhood (play age), middle childhood (school age), and adolescence (puberty through post-puberty). Various childhood factors could affect a person's attitude formation.

The concept of childhood emerged during the 17th and 18th centuries, particularly through the educational theories of the philosopher John Locke and the growth of books for and about children. Previous to this point, children were often seen as incomplete versions of adults.

The term childhood is non-specific and can imply a varying range of years in human development. Developmentally and biologically, it refers to the period between infancy and adulthood. In common terms, childhood is considered to start from birth. Some consider childhood as a concept of play and innocence which ends at adolescence. In the legal systems of many countries, there is an age of majority when childhood officially ends and a person legally becomes an adult. The age ranges anywhere from 15 to 21, with 18 being the most common.

Early childhood follows the infancy stage and begins with toddlerhood when the child begins speaking or taking steps independently. While toddlerhood ends around age three when the child becomes less dependent on parental assistance for basic needs, early childhood continues approximately through years seven or eight. According to the National Association for the Education of Young Children, early childhood spans the human life from birth to age eight. At this stage children are learning through observing, experimenting and communicating with others. Adults supervise and support the development process of the child, which then will lead to the child's autonomy. Also during this stage, a strong emotional bond is created between the child and the care providers. The children also start to begin kindergarten at this age to start their social lives.
