Episodic memory in patients with focal frontal lobe lesions.

@article{citeulike:2925932, abstract = {Episodic memory was evaluated in patients with unilateral, frontal lobe damage and matched controls using a list-method directed forgetting paradigm. Directed forgetting instructions (forget vs. remember the word), encoding instructions (learn vs. judge the word) and test format (recall vs. recognition) were manipulated in order to explore how variations in encoding and retrieval affect verbal memory. Controls demonstrated a normal directed forgetting effect in recall and less directed forgetting in recognition. Patients with left frontal (LF) damage did not show directed forgetting in either recall or recognition and patients with right frontal (RF) damage showed directed forgetting in recall, but not in recognition. Furthermore, the LF group recalled significantly more of the judge than learn words, suggesting that this group's performance improves by providing them with an encoding strategy. Conversely, the RF group's performance did not depend on encoding instructions and their recognition memory was impaired relative to the other two groups when they were instructed to judge the words. Our results suggest that (a) patients with LF damage show deficits in the rehearsal of to-be-remembered information, (b) whereas patients with RF damage show impairments in recognition memory. Furthermore, both patient groups show a lack of directed forgetting when familiarity-based processes guide performance.}, address = {Department of Clinical and Health Psychology, University of Florida, FL, USA. camcdonald@ucsd.edu}, author = {McDonald, C.
