What does the cognitive approach to depression suggest?

The cognitive explanation of depression suggests that negative thoughts and belief's cause depression. Beck's cognitive triad suggests that there are three focuses of negative thinking: the self (I am stupid), the future (I will always be stupid) and the world (no body loves me). Beck also proposed systematic bias', also known as faulty thinking. These include selective abstraction (focusing on the worst), magnification (making a small problem big), minimisation (making something positive seem small or non-existent), personalisation (blaming everything on yourself) and dichotomous thinking (everything seems black and white - there is no inbetween).
