Fifty-two subjects between ages 40 and 79 years were administered a questionnaire assessing their ability to recall semantic information about famous people from 4 different decades and to recollect its episodic source of acquisition together with autonoetic consciousness via the remember-know paradigm. In addition, they underwent a battery of standardized neuropsychological tests to assess episodic and semantic memory and executive functions. The analyses of age reveal differences for the episodic source score but no differences between age groups for the semantic scores within each decade. Regardless of the age of people, the analyses also show that semantic memory subcomponents of the famous person test are highly associated with each other as well as with the source component. The recall of semantic information on the famous person test relies on participants' semantic abilities, whereas the recall of its episodic source depends on their executive functions. The present findings confirm the existence of an episodic-semantic distinction in knowledge about famous people. They provide further evidence that personal source and semantic information are at once distinct and highly interactive within the framework of remote memory.
对52名年龄在40至79岁之间的受试者进行了问卷调查，评估他们回忆来自4个不同十年的名人语义信息的能力，以及通过记住-知道范式回忆其情景来源和自我感知意识的能力。此外，他们还接受了一系列标准化的神经心理学测试，以评估情景记忆、语义记忆和执行功能。年龄分析显示情景来源得分存在差异，但每个十年内语义得分在年龄组之间没有差异。无论年龄大小，分析还表明名人测试的语义记忆子成分之间以及与来源成分之间高度相关。名人测试中语义信息的回忆依赖于参与者的语义能力，而其情景来源的回忆则取决于他们的执行功能。目前的研究结果证实了在名人知识方面存在情景-语义区分。它们进一步证明，在遥远记忆的框架内，个人来源和语义信息既相互区别又高度互动。
