Abstract

Novel tests of semantic memory (SM)-for example, memory for news events (NE; news facts) or famous personalities-are useful for estimating the severity of retrograde amnesia. Individuals with mild cognitive impairment exhibit relatively intact SM/language on traditional neuropsychological tests but exhibit consistent impairment on novel tests of SM, suggesting novel SM tests are dissimilar from traditional SM tests. To identify the relationship between NE memory and traditional cognitive measures, older adults (N = 51) completed a traditional neuropsychological battery and the Retrograde Memory News Events Test (RM-NET; a new test that robustly measures NE memory across the adult life span with high temporal resolution), and the relationship between performance on these tests was examined. Total RM-NET scores were more closely aligned with episodic memory scores than SM scores. The strength of the association between NE scores and episodic memory scores decreased as the age of NE memory increased. Tests of news events appear to reflect performance on traditional tests of episodic memory rather than SM, especially when recent news events are tested.

新闻事件回溯记忆测试（RM-NET）以及新闻事件记忆与标准神经心理测试成绩之间的关系。

语义记忆（SM）的新测试——例如，对新闻事件（NE；新闻事实）或著名人物的记忆有助于估计逆行性健忘症的严重程度。轻度认知障碍的个体在传统的神经心理学测试中表现出相对完整的SM/语言，但在SM的新测试中却表现出一致的障碍，这表明新的SM测试与传统的SM测试不同。为了确定NE记忆与传统认知测量之间的关系，老年人（N=51）完成了传统的神经心理学测验和逆行记忆新闻事件测验（RM-NET；一种新的测试，以高时间分辨率稳健地测量整个成年寿命的NE记忆），并检查了这些测试中表现之间的关系。RM-NET总分与情景记忆得分的一致性高于SM得分。NE评分和情景记忆评分之间的关联强度随着NE记忆年龄的增加而降低。新闻事件测试似乎反映了传统情景记忆测试的表现，而不是SM，尤其是在测试最近的新闻事件时。

期刊介绍： The neurobiology of learning and memory is entering a new interdisciplinary era. Advances in neuropsychology have identified regions of brain tissue that are critical for certain types of function. Electrophysiological techniques have revealed behavioral correlates of neuronal activity. Studies of synaptic plasticity suggest that some mechanisms of memory formation may resemble those of neural development. And molecular approaches have identified genes with patterns of expression that influence behavior. It is clear that future progress depends on interdisciplinary investigations. The current literature of learning and memory is large but fragmented. Until now, there has been no single journal devoted to this area of study and no dominant journal that demands attention by serious workers in the area, regardless of specialty. Learning & Memory provides a forum for these investigations in the form of research papers and review articles.
