Early and Middle Adulthood

As individuals move through early and middle adulthood, a variety of physical changes take place in the body.

Cognition changes over a person's lifespan, peaking at around age 35 and slowly declining in later adulthood.

Early and middle adulthood is influenced by a number of social and emotional factors, such as work and interpersonal relationships.

Several theories examine how interpersonal relationships form and develop during adulthood.
