birth order, personality development


Personality development, and even intelligence, is influenced by family members once a child is brought into the world. The family, especially the siblings, has a notable impact on the child’s development. Siblings provide the first social interactions children have, both positive and negative. Siblings affect the personality and intellectual development of individuals via differences in family responsibilities and changes that arise in the home environment as more children are added to the household. Older siblings will likely have stronger leadership skills because of these responsibilities, and younger children may not receive as many benefits in intellectual abilities because of these changes in the home. Results are shown through a variety of longitudinal and observational studies. Although these studies are limited due to the increasing belief that peers have a greater impact on the development of individuals, the studies reviewed here promote the relationship between personality and intellectual development and the birth order of children in a large family.
