Paying attention to the world around you: applied problem. The need to solve a problem: theory testing. Conduct a study to try to test whether the prediction is correct: new question generated from past research.

What is a theory: should summarize & account for the existing data, a statement about relationships between abstract variables, use theory to make predictions about behaviour. E. g. , cognitive dissonance when you have 2 opposing ideas at the same time, you are uncomfortable: takes constructs & tries to relate them to each other.
