Lifespan development is the scientific study of the changes that occur in human beings over the course of their lives. This field of study looks at both physical and psychological changes, and how they interact with each other. Researchers who specialize in lifespan development seek to understand how different people age, and what factors influence this process.
One of the most important aspects of lifespan development is research on aging. Scientists have only recently begun to understand the complex biological processes that take place during aging, and there is still much to learn. However, we do know that aging is a natural process that happens to everyone, and that it cannot be prevented. We also know that there are many different ways to age well – by staying physically active, eating a balanced diet, maintaining social connections, and so forth.
Developmental psychologists often study children and adolescents, as this is a time when people experience many significant changes. However, lifespan development research can encompass people of all ages – from infants to older adults. In fact, studying developmental change across the entire lifespan can give us a better understanding of individual differences in how people grow and change over time.
