The present study was conducted to evaluate the effect of  training on personality formation and mental development of childhood and adolescence. It is important to understand how children develop physically, socially, emotionally and intellectually to know that all areas of development are equally as important as each other, and that all impact on one another. Biological and cognitive changes transform children’s bodies and minds. Social relationships and roles change dramatically as children enter school, join  programs,  and  become  involved  with  peers  and  adults  outside  their  families. The years between ۶ and ۱۴ middle childhood and early adolescence are a time of important developmental advances that establish children’s sense of identity. A child’s development can be measured through social, emotional, intellectual, physical and language developmental milestones.  All children and young people follow a similar pattern of development so the order in which each child advances from one milestone to the next will be roughly the same. However, each child will develop at a different rate and their development may not progress evenly across all areas
