This paper from last spring describes new evidence for our hyperfocusing theory of cognitive dysfunction in schizophrenia.  Remarkably, we found that people with schizophrenia were actually better able to focus centrally and filter peripheral distractors than were control subjects. Under the right conditions, we even observed a (slightly) larger P3 wave in patients than in controls.
