- The area assumes that all thoughts, feelings and behaviors have a biological cause

- All that is psychological is first biological

- Human genes have adapted our physiology and behaviour to the environment

- Psychology should investigate the brain, nervous system and genes

- regions of the brain:

     - Sperry: Split-brain

     - Casey: Delay of gratification

- Brain plasticity:

     - Blakemore and Cooper: Cats

     - Maguire: Taxi Drivers

- Very scientific and objective

- strong counter argument to nurture debate which states that we learn behaviour

- research methods are very reliable

- reductionist as it ignoroes other explanations of behavior such as the environment

- does not explain how the mind and body interact

- research methods lack ecological validity
