Biological Perspective
Also called biopsychology or physiological psychology and is related to neuroscience
Deals with microscopic physical and
genetic components that contribute to
certain behaviors
Uses DNA as well as scientific instruments such as
MRI and PET scans to see how drugs, disease, and brain
damage affect thought processes and behaviors
Background

Stated that behaviors or phsyical traits
that benefitted the organism would be
selected upon. Started the belief that
behaviors can be biological.
Sheldon
Body type dictates
personality
Although he was for the most
part wrong, his assumption that
certian body types made certain
personalities was an important
step for biological psychology
Sperry
Proved localization
Severed corpus collosum in monkeys and found that their performance in tasks differed with changing visual fields
Proved that different parts of
the brain control different mental
abilities, thus proving localization
Nature vs
Nurture
Twin Studies
Shown that separated twins have
similiar "nurtured" characteristcs,
showing the genetic role in
many psychological aspects of
humans
Memory
EEG scans have shown
that different parts of the
brain deal with different
types of memory
Short Term at the
parietal and frontal
lobes
Long term at the
hippocampus
Emotions and
the Brain
PET scans can show which
parts of the brain are associated
with certain emotions and how
these can be affected by brain
damage
Criticisms
Questioning the generalization
of findings of biological psychology
because all humans don't think the
same
Do all humans have the same
brain structure for thinking?

Survey of Feelings
on a "positive" religious
holiday
Two groups of religous
christians and non-religious
people
Survey them based on
thier feelings of happiness,
how they feel toward the day,
and how they look toward
the future
Variables are whether of not
the people are religous or not
Also the answers to their feelings
on a numerical scale of 1 to 10
Expect to find that religious
people will show a better
attitude toward their day and
the future than non-religious
people
Ethical issues are that some of
the people may have strong
emotional reactions to questions.
Also they may feel an invasion of
privacy
