DESCRIPTION (provided by applicant): This project aims to investigate the status of associative recognition memory in global amnesia in the context of a dual-process model that postulates two separate bases for recognition performance, recollection and familiarity. Four studies will be conducted to examine this issue. The goal of Experiment 1 is to determine whether associative recognition for unrelated word pairs, as compared to single word recognition, is disproportionately impaired in amnesia. Experiment 2 compares associative memory for stimuli in which there is a pre-existing representation of an association (i.e., compound words) to stimuli in which there is not (i.e., unrelated words pairs). Experiment 3 examines whether associative recognition in amnesia is better preserved under the former conditions. Finally, Experiment 4 aims to specify the nature of the familiarity process contributing to amnesics? associative recognition (i.e., conceptual or perceptual) for compound stimuli.

描述（由申请人提供）：该项目旨在调查 整体失忆症中联想识别记忆的状态 双进程模型，假设两个独立的识别基础 表现、回忆和熟悉度。将进行四项研究 检查这个问题。实验 1 的目标是确定是否 与单个单词相比，对不相关单词对的关联识别 失忆症患者的认知能力受到严重损害。实验2比较 对刺激的联想记忆，其中存在预先存在的表征 与不存在刺激的关联（即复合词） （即不相关的单词对）。实验 3 检查是否具有联想性 在以前的条件下，失忆症的认知能力得到了更好的保存。 最后，实验 4 旨在明确熟悉过程的本质 导致健忘症？联想识别（即概念或 知觉）复合刺激。
