Abnormality - Cognitive

A person's thoughts are responsible for their behaviour. Deals with the way information is processed in the brain and the impact of this behaviour. How a person perceives, anticipates and evaluates events has an effect on behaviour. 

Healthy thoughts and cognitions lead to normal behaviour whereas faulty thoughts and cognitions lead to abnormal behaviour.

Irrational Thinking - Ellis

- Assumes emotional problems can be attributed to distortions in thinking process.
- Distortions take the form of maladaptive thoughts.
- Polarised thinking: Seeing everything in black and white.
- Magnification and minimisation: person may magnify failure and minimise success.

C - Healthy negative emotion
