Damage to the lateral prefrontal cortex impairs familiarity but not recollection
چکیده انگلیسی

Frontal lobe lesions impair recognition memory but it is unclear whether the deficits arise from impaired recollection, impaired familiarity, or both. In the current study, recognition memory for verbal materials was examined in patients with damage to the left or right lateral prefrontal cortex. Words were incidentally encoded under semantic or phonological orienting conditions, and recognition memory was tested using a 6-point confidence procedure. Receiver operating characteristics (ROCs) were examined in order to measure the contributions of recollection and familiarity to recognition memory. In both encoding conditions, lateral prefrontal cortex damage led to a deficit in familiarity but not recollection. Similar deficits were observed in left and right hemisphere patients. The results indicate that the lateral prefrontal cortex plays a critical role in the monitoring or decision processes required for accurate familiarity-based recognition responses.


► Frontal lobe lesions impair recognition memory; unclear which memory processes are influenced.
► Used receiver operating characteristics to measure recollection and familiarity.
► Lateral prefrontal patients had deficits in familiarity but not recollection.
