How does developmental psychology study human growth?

Developmental psychology is a branch of psychology that focuses on studying human growth and development over the lifespan. It examines how individuals change physically, cognitively, emotionally, and socially from infancy to old age. This field of psychology explores the various factors that influence human development, including genetics, environment, and social interactions.

Lifespan Perspective

Developmental psychology takes a lifespan perspective, considering development as a continuous process that occurs throughout the entire life span. It looks at how individuals progress through different stages of development from infancy, childhood, adolescence, adulthood, to old age.

Influences on Development

Researchers in developmental psychology study the interplay between nature and nurture, examining the roles of genetics and environment in shaping human growth. They investigate how genetic predispositions interact with environmental influences and social interactions to impact psychological, cognitive, physical, emotional, and social development.

Psychological Theories of Development

Developmental psychologists also apply various psychological theories to understand human growth, such as Piaget's theory of cognitive development, Erikson's psychosocial theory, and Vygotsky's sociocultural theory. These theories provide frameworks for examining developmental milestones and understanding the factors that contribute to individual differences in development.
