Convincingly demonstrates that there is almost no cognitive impairment in outpatients reporting high levels of depressive symptoms—when patients failing CARB or the WMT are excluded.  Green (personal communication) replicated the findings using ONLY patients meeting DSM-IV criteria for depression. *** Authors of the latter paper were selected to receive the Nelson Butters award at the National Academy of Neuropsychology annual conference in Dallas, TX, 2003 (best empirical paper in neuropsychology for the year 2002).
