The creation of false memories within the Deese-Roediger-McDermott (DRM) paradigm has been shown to be sensitive to many factors such as task instructions, participant mood, or even presentation modality. However, do other simple perceptual differences also impact performance on the DRM and the creation of false memories? This study explores the potential impact of changes in perceptual disfluency on DRM performance. To test for a potential influence of disfluency on false memory creation, participants viewed lists under either perceptually disfluent conditions or not. Results indicated that disfluency did significantly impact performance in the DRM paradigm; more disfluent presentations significantly increased the recall and recognition of unpresented information, although they did not impact recall or recognition of presented information. Thus, although disfluency did impact performance, disfluency did not produce a positive benefit related to overall task performance. This finding instead suggests that more disfluent presentations can increase the likelihood that false memories are created, and provide little positive performance benefit.
在迪ese-罗迪格-麦克德莫特（DRM）范式中，错误记忆的产生已被证明对许多因素敏感，如任务指令、参与者情绪，甚至呈现方式。然而，其他简单的感知差异是否也会影响DRM任务的表现以及错误记忆的产生呢？本研究探讨了感知流畅性变化对DRM任务表现的潜在影响。为了测试流畅性对错误记忆产生的潜在影响，参与者在感知流畅或不流畅的条件下观看列表。结果表明，流畅性确实对DRM范式中的表现有显著影响；更不流畅的呈现显著增加了对未呈现信息的回忆和识别，尽管它们没有影响对呈现信息的回忆或识别。因此，虽然流畅性确实影响了表现，但流畅性并没有产生与整体任务表现相关的积极益处。这一发现反而表明，更不流畅地呈现信息会增加产生错误记忆的可能性，且几乎没有带来积极的表现益处。
