All that is psychological is first physiologicalreductionist!
All behavior has a cause – deterministic!
Psychology should investigate the brain,
neurochemistry and genetics


4.
Patterns of behavior can be inherited
Cognitions, emotions and behaviors are products of
neurotransmitters in the brain and hormones in the
body
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.


Machine detects energy
given off by tracer &
converts to 3-D picture


Attached to glucose
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
