Child’s Age

A group of children of different ages

There are several possible ways to study a child’s development:


  • Consider the child as a whole that changes through stages development. However, the emphasis is not placed on the living child as a whole, which goes through and changes through different stages, but on the developmental stage and age. In this case, these stages become the most important factors of development. This approach emphasizes that all children are at the same level of development and neglects individual differences.
  • We can study some particular aspects of children’s development such as social development, intellectual development, emotional development, etc.
  • There is also a third approach, called Experimental Child Psychology, which involves manipulating the situation in which the child becomes aware of himself but also revealing the role of learning in development.

Developmental standards are sometimes called milestones – they define the recognized pattern of development that is expected of children. Each child develops uniquely, and the use of norms helps to understand these patterns of development while recognizing the great difference between individuals.
