PSYB01 Lecture 1
Slide 1 Why Learn Research Methods?
- Become a better consumer of research
o Psychology study says violent video games makes kids riskier drivers
o Does Facebook make you fat?
The above are articles on example studies; we study methods so that we can
question the procedures, findings, etc. of the study to determine if we believe
it or not
- Research is built on previous research
- Often used in work settings
- Used in making policy decisions
Slide 2 The Scientific Approach
- Have an observation/insight develop a hypothesis (a prediction of what you think you will
find) testing of hypothesis findings
- Previous findings, insights, and theories contribute to the scientific approach
Slide 3, 4 Goals of Science
- 1. Description of Behaviour
o What happens, how often, where, under what circumstances, etc.
o Observations are systematic and precise
o Use large groups to even out individual differences
- 2. Prediction of Behaviours
o What will happen to B if A has a certain value?
- 3. Determining cause(s) of Behaviour
o Does A cause B?
Temporal precedence (A happens before B)
Covariation (A varies along with B) but they do not need to vary in the
same way (i.e. A may increase, while B decreases)
No other alternative explanations
- 4. Explanation of Behaviour
o Understanding why a behaviour occurs

Document Summary

The above are articles on example studies; we study methods so that we can question the procedures, findings, etc. of the study to determine if we believe it or not. Have an observation/insight develop a hypothesis (a prediction of what you think you will find) testing of hypothesis findings. Previous findings, insights, and theories contribute to the scientific approach. Covariation (a varies along with b) but they do not need to vary in the same way (i. e. a may increase, while b decreases)
