Approaches to knowledge- Rationalism
developing ideas using existing ideas and logic
Approaches to knowledge- Empiricism

Approaches to knowledge- Science

4 science values
(science values) accuracy

-free from biased
*not let biases from getting in the way when collecting data
(science values) Skepticism
multiple attempts to verify its claim
(science values) open-mindness
-ability to adapt.
-open to changing mind
5 Logical structure of scientific method
(components of scientific method) laws
-can be tested eveyrtime and come out the same result everytime
(components of scientific method) theory
-system of ideas that explain complex phenomena
(components of scientific method) hypothesis
(components of scientific method) Experimentation
test hypothesis or set
(components of scientific method) Observations
real subjects behave, no interference
5 verifiability of claims
(5 verifiability of claims) Public process
-research is out in open.
*how it was done and how can it be repeated
(5 verifiability of claims) Repeatability
the research has to be able to be repeated by someone that reads the research paper
(5 verifiability of claims) operational definition
ex) want to test a study on aggressivity.
how do we go about to bring that behaviro out to measure
(5 verifiability of claims) Falsification
tested in a way to come out false.
* trying to prove your research false
(5 verifiability of claims) Parsimony
the simpler the better
merit of scientific research judeged by other scientists
*will receive the highest scrutiny

-we must be able to tie these behaviors to mental events
(best mechanism for studying something that exists in mental world) Overt behavior
how hard someone punches bag
(best mechanism for studying something that exists in mental world) Questionnaire responses
*why choose 5 and not 8 on scale from 0-10
