Lifespan Development Definition
The term lifespan development refers to age-related changes that occur from birth, throughout a persons' life, into and during old age.
The six stages of lifespan development are:
Infancy, Childhood, Adolescence, Early Adulthood, Middle Age, Older Age.
Birth-two years. While the infant is dependent on adults for most things, many psychological characteristics are rapidly developing. During this stage, the bond that develops between the infant and their primary caregiver is important in terms of the infant's later emotional development.
Two-ten years. During this stage, children become increasingly independent from their parents as they learn to do things themselves and gain more self-control. During this stage, children's cognitive skills develop and they also begin to develop an understanding of what is right and wrong.
Ten-twenty years. The onset of puberty marks the beginning of adolescence. It is dominated by seeking independence from parents and developing one's own identity. Compared to the child, an adolescent's thought processes are more logical, complex and idealistic.
Twenty-forty years. This is the stage of establishing personal and financial independence and establishing and consolidating a career. For many, it is also the time in which individuals select a partner, develop an ongoing intimate relationship and begin a family.
Forty-sixty five years. This is a period of expanding social and personal involvements and responsibilities, advancing a career, and supporting offspring in their development to becoming mature individuals.
