　View Summary

In the present study, we used the typical false recognition paradigm to test a hypothesis that the ventromedial prefrontal cortex (VMPFC) mediates context judgment and retrieving past events. Eight VMPFC patients and ten normal control subjects were first requested to learn 18 sets of 14 semantic associates. In the test phase, the participants were asked to recognize for pairedwords including true words, related lures, and unrelated lures. The VMPFC patients showed significantly higher false alarm rate than the normal subjects for lure words. A further analysis suggests that the VMPFC patients were more likely to fail to judge contexts and to retrieve past events.

　View Summary

<p>In the present study, we used the typical false recognition paradigm to test a hypothesis that the ventromedial prefrontal cortex (VMPFC) mediates event-category judgement and retrieving past similar events. Eight VMPFC patients and 10 normal subjects were first requested to learn 18 sets of 14 semantic associates. In the test phase, participants were asked to recognize paired words including true words, related lures, and unrelated lures. The VMPFC patients showed significantly higher false alarm rates than the normal subjects for lure words. A further analysis suggests that the VMPFC patients succeeded in judging the event category, yet they were more likely to fail to retrieve past similar events. © 2001 Academic Press.</p>

95. Directed forgetting effect in patients with frontal lobe damage

　View Summary

<p>To study the role of the frontal lobes in episodic remembering, directed forgetting effect of frontal patients was examined. Eight patients with frontal lobe damage, eight patients with temporoparietal lobe damage, and eight normal subjects were given a list of 24 nouns (12 remember-cued words and 12 forget-cued words). On the list method (Experiment 1), frontal patients were significantly impaired in recalling remember-cued items whereas they recalled inappropriate forget-cued items. Frontal patients showed much less directed forgetting effect than two control groups. On the item method (Experiment 2), performance of frontal patients was in between the other two groups. Patients with frontal lobe damage appeared to have impaired retrieval inhibition, and their retrieval process is interfered with by inappropriate stimuli which should be forgotten. © 2001 Academic Press.</p>

　View Summary

<p>Prospective memory involves memory for future intentions in our everyday lives and it is one of the hot topics in current memory research. We reexamined what is prospective memory and discussed how intentions had been conceived of in the history of psychology. We emphasize the necessity of classifying a form of remembering intentions into the self-initiated existence-remembrance and its content-remembrance. Many studies on prospective memory in recent decades were reviewed with respect to the following perspectives: (1) how intentions are recollected, (2) what is remembering intentions based on, (3) how we attempt to avoid forgetting to do things, and (4) what is neuropsychological mechanism of remembering intentions. Requirements for experimental research on prospective memory are summarized and future directions are discussed.</p>
