Scientific Methodology
Crash Course: Psychological Research
Psychological Research
- For any events and phenomenon, you need a conclusion
- But your intuition is not always right. In fact, sometimes it is exactly wrong
- Hindsight Bias: I-knew-it-all-along phenomenon
SCIENTIFIC METHODS
Operationalizing
1. Ask general question and need a theory which explains something
2. Turn it into a testable prediction: hypothesis
3. Test it with a replicable experiment (replication: in order to generalize)
Case Study:
Look at the cases to determine or understand people’s mind and behavior
Naturalistic Observation:
It is great at describing behavior, but they are very limited in explaining it. (can observe the behavior but cannot really understand the mind behind it)
Survey:
An interview to people, great way to access people consciously held attitudes and beliefs but how to ask question is very tricky because a word choices can influence people’s answers and results.
Sampling Bias, Random Sample= the representative have equal possibility to be tested
