| Abstract | People sometimes falsely recognize novel episodes as previously experienced. We used the typical false recognition paradigm to know the role of the frontal lobe in false recognition. Eight patients with orbitofrontal cortex lesions and ten normal control subject were first requested to learn 18 sets of 14 semantic associates. In the test phase, participants were asked to recognize for paired-words including true words, related lures, and unrelated lures. The patients showed significantly higher false alarm rate than the normal control subjects for lure words. A further analysis suggests that the patients were more likely to fail to retrieve past similar events. This notion was also supported by a functional MRI study. |
