Functionalism is an early approach to psychology that concentrated on what the mind does-the functions of mental activity-and the role of behavior in allowing people to adapt to their environment.
The perspective that replaced structuralism is known as functionalism. Rather than focusing on the mind’s structure, functionalism concentrated on what the mind does and how behavior functions.
Functionalism is a school of psychology which emphasizes the Junctions or activities of the mind rather than its content, which is the emphasis of its rival, structuralism.
