Development is the study of the way people change, from the first moments of conception right through the life span to old age and death. Development begins from the moment conception occurs. The definition emphasizes that development is an ongoing process, right through life until the moment of death. This definition also states that development is about a person changing in some way. Changes within the development can be examined in two ways:Quantitative changes look at measurable changes in a persons development. It occurs when individuals acquire novel information and experiences like, the individuals become stronger, bigger, gain more weight or height.Qualitative changes reflect a new stage that is different, in quality, from what was happening before. Examples would be going from crawling to walking stage or beginning to talk using words from a babbling stage. These examples show a change in the quality of movement and the quality of communication.Hence, we can conclude that in the context of children, 'development' includes both qualitative and quantitative changes.
