Much research has shown both cognitive deficits and negatively valenced cognitive biases to be present in depression. Rumination - the tendency to think repetitively about ones own thoughts feelings, symptoms and problems - has also been linked to cognitive deficits and biases. It has been proposed that rumination which is a risk factor for degression and is consistently found to be elevated in currently depressed patients, may cause cognitive deficits in depression by overwhelming cognitive resources. Rumination may also cause negative cognitive biases by focussing attention onto negative over positive information and therefore causing it to be over-consolidated into memory.
