DESCRIPTION (Applicant's abstract): Item memory is memory for occurrence of events (e.g., Was this word spoken?). Source memory is memory for the source of an occurrence (e.g., Did A say it?). There is evidence that source memory is particularly vulnerable to aging and that it is differentially affected by different types of brain damage (e.g., frontal versus temporal). Signal Detection Theory has to date been extensively applied to item memory but has not been applied to source memory. When extended to cover source memory, it offers new and interesting predictions concerning the relation between source and item memory. The implications of Signal Detection Theory for performance of normal participants will be tested. The results will be compared with the results predicted by a different approach to memory, the family of threshold theories. The Signal Detection Theory will be applied then to evaluate the effects of aging and specific brain damage on memory.

描述(申请人摘要)：项目记忆是发生的记忆 事件(例如，这个词是说出来的吗？)源内存是用于源的内存 一个事件(例如，A说了吗？)有证据表明，源内存是 特别容易受到衰老的影响，而且它受到 不同类型的脑损伤(例如，额叶和颞叶)。讯号 到目前为止，检测理论已被广泛应用于项目记忆，但 未应用于源内存。当扩展到涵盖源内存时，它 提供了关于来源之间关系的新的和有趣的预测 和物品记忆。信号检测理论对性能的影响 正常参与者将接受测试。结果将与 通过不同的记忆方法预测的结果，阈值家族 理论。然后将应用信号检测理论来评估 衰老和特定的脑损伤对记忆的影响。
