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.

新闻事件逆行记忆测试（RM-NET）以及新闻事件记忆与标准神经心理学测试表现之间的关系

语义记忆（SM）的新颖测试——例如新闻事件（NE；新闻事实）或著名人物的记忆——对于估计逆行性遗忘症的严重程度很有用。患有轻度认知障碍的个体在传统神经心理学测试中表现出相对完整的 SM/语言，但在新的 SM 测试中表现出一致的损伤，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电池测试和逆行记忆新闻事件测试 (RM-NET；一项新测试，可在成人生命周期内稳健地测量 NE 记忆，其中包括：高时间分辨率），并检查了这些测试的性能之间的关系。与 SM 分数相比，RM-NET 总分数与情景记忆分数更接近。NE 评分与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。新闻事件的测试似乎反映了传统情景记忆测试的表现，而不是 SM，特别是在测试最近的新闻事件时。
