Maturation could be physical, psychological, or social (PDE702 Pg 199). While growth involves quantitative changes (such as physical and mental changes) in an organism (PDE702 Pg 77). On the other hand, development refers to a series of orderly changes in the physical status of an individual. It occurs in body size i.e. weight and height; body proportions i.e. shapes as a result of changes in body size (PDE702 Pg 109).
