Lec 7 Research Methods
• Most psychologists deem themselves scientist practitioners
• Psychologist learned under scientific process
• Boulder Model Psychology will be scientist practitioners. Psychologists learn
methods of science before become practitioners.

Hypothesis based testing. Will get a positive outcome most of the
time with the scientific method of thinking. Most likely to lead to
correct outcome. Time consuming.
