The biological approach in psychology explores how biological structures and processes influence human behavior and mental processes. It emphasizes the role of genetics, brain function, and evolutionary factors in shaping psychological phenomena.
Key points:
- Assumes all psychological processes have a biological basis
- Focuses on genetic influences, neurochemistry, and nervous system function
- Uses twin studies to examine genetic contributions to behavior
- Applies evolutionary theory to explain adaptive behaviors
- Employs scientific methods like brain imaging techniques
- Has real-world applications in developing treatments for mental illness
- Faces criticism for being overly deterministic and reductionist
