PATHOLOGICAL FALSE ALARM RATES FOLLOWING DAMAGE TO THE LEFT FRONTAL-CORTEX

In this study we present further data on case JB who developed memory impairment following a ruptured aneurysm of the anterior communicating artery which resulted in damage centered on the frontal cortex. The d ata reveal that JB's memory impairment is characterized by a retail im pairment in which intrusion rates are abnormally high and a recognitio n deficit characterized by an exceptionally high false alarm rates. A comparison is made between this case and other recent cases involving impairments with a similar etiology. Theoretical interpretations of JB 's deficit are also considered.
