2. 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

3.  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

4.  Measures & records electrical activity (neuron pulses) in the brain  ACTIVITY

5.  X-ray photographs that reveal detailed pictures of physical structures of the body.  Allows us to study STRUCTURES

6.  Magnetic field and radio wave energy to create detailed pictures of structures in the body  More detailed that CT scan  STRUCTURES

7.  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

8.  Increased blood flow to active areas of the brain  Detects blood oxygen levels  Allows us to directly observe brain functioning  ACTIVITY  http://www.science friday.com/videos/ watch/10104 http://www.science friday.com/videos/ watch/10104
