1. All that is psychological is first physiological- reductionist!

2. All behavior has a cause – deterministic!3. Psychology should investigate the brain,

neurochemistry and genetics Patterns of behavior can be inherited Cognitions, emotions and behaviors are products

of neurotransmitters in the brain and hormones in the body

4. Animals may be studied as a means of understanding human behavior

CAT scan, PET scan, MRI, fMRI Make it possible to:

directly study living brains in action to correlate specific areas of brain damage

with specific changes in a person’s personality or cognitive abilities

Measures & records electrical activity (neuron pulses) in the brain

ACTIVITY

X-ray photographs that reveal detailed pictures of physical structures of the body.

Allows us to study STRUCTURES

Magnetic field and radio wave energy to create detailed pictures of structures in the body

More detailed that CT scan

STRUCTURES

Identifies active cellular areas of the body.

Injection of radiotracer, travels through body and is absorbed by organs and tissues. Attached to glucose

Machine detects energy given off by tracer & converts to 3-D picture Active neurons burn

more glucose ACTIVITY

Increased blood flow to active areas of the brain

Detects blood oxygen levels

Allows us to directly observe brain functioning
