NM, who suffered traumatic brain injury (TBI) to the prefrontal cortex (PFC), was compared with a diffuse axonal injury (DAI) patient on tasks of free recall, cued recall and recognition memory. We manipulated the familiarity of items to explore the effects of item strength on retrieval. On free recall, NM performed best during the high-familiarity picture(More)

The overall group differences revealed that many patients could not reach the task criterion regardless of the location of damage and the shift condition of the task. When we compared patients with subcortical and(More)
