Final answer:
Urie Bronfenbrenner developed the Ecological Systems Theory, which emphasizes the diverse environmental factors influencing human development.
Step-by-step explanation:
The psychologist Urie Bronfenbrenner is best known for developing the Ecological Systems Theory. This theory suggests that development occurs based on complex interactions among various environments such as school, family, and community. The Ecological Systems Theory is a comprehensive framework that examines how the inherent qualities of a child and the characteristics of the external environment can influence how the child grows and develops.
While other theorists, such as Sigmund Freud with Psychoanalysis and B.F. Skinner with Behaviorism, offered different perspectives on psychological development, Bronfenbrenner's approach is unique in its focus on the multiple layers of environment that affect an individual's development. His theory has had a profound impact on understanding the complexities of human development within a societal context.
