Veridical memory for presented list words and false memory for nonpresented but related items were tested using the Deese/Roediger and McDermott paradigm. The strength and density of preexisting connections among the list words, and from the list words to the critical items, were manipulated. The likelihood of producing false memories in free recall varied with the strength of connections from the list words to the critical items but was inversely related to the density of the interconnections among the list words. In contrast, veridical recall of list words was positively related to the density of the interconnections. A final recognition test showed that both false and veridical memories were more likely when the list words were more densely interconnected. The results are discussed in terms of an associative model of memory, Processing Implicit and Explicit Representations (PIER 2) that describes the influence of implicitly activated preexisting information on memory performance.
使用迪斯/罗迪格和麦克德莫特范式测试了对呈现列表单词的真实记忆以及对未呈现但相关项目的错误记忆。对列表单词之间以及从列表单词到关键项目的先前存在的连接强度和密度进行了操纵。在自由回忆中产生错误记忆的可能性随从列表单词到关键项目的连接强度而变化，但与列表单词之间的互连密度呈负相关。相比之下，列表单词的真实回忆与互连密度呈正相关。最后的识别测试表明，当列表单词之间的互连更密集时，错误记忆和真实记忆都更有可能出现。根据记忆的关联模型“处理内隐和外显表征（PIER 2）”对结果进行了讨论，该模型描述了内隐激活的先前存在信息对记忆表现的影响。
