Psychological Theory:

Psychological theories are systems of ideas that can explain certain aspects of human thoughts, behaviours and emotions. Psychology researchers create these theories to make predictions for future human behaviours or events that may take place if certain behaviours exist. These theories are based on a hypothesis, which is backed by evidence. Thus, the two key components of a psychological theory are:
1. It must describe a behaviour.
2. It must make predictions about future behaviours.
