Urie Bronfenbrenner's Ecological Systems Theory is a comprehensive model of human development that outlines how different environmental systems influence individual growth and behavior. According to this theory, there are five interlocking contextual systems, each nested within the other, which interact to shape human development. These systems are the microsystem, mesosystem, exosystem, macrosystem, and chronosystem.
Life span refers to the ongoing process that we go through while growing up. It is the period of time from conception extending to death.
Life-span developmental psychology is the field of psychology which involves the examination of both constancy and change in human behaviour across the entire life span, that is, from conception to death (Baltes, 1987).
Development refers to the biological and psychological changes that occur in human beings between birth and the end of adolescent, as the individual progresses from dependency to increasing autonomy.
Developmetal psychology refers to development throughout the lifespan, and pediatrics, the branch of medicine relating to the care of children.
Growth refers to the development of children from birth to adolescence.
Four areas in which children’s growth and
development take place:
a) Physical
b) Psychological and
cognitive
c) Social and emotional
d) Sexuality and gender identity
