Abstract

Background: False memory has been extensively studied using the Deese/Roediger-McDermott paradigm. Despite the robustness of the effect, there is wide variability in the results, which is not fully understood.

Method: Three experiments independently examined the role of backward associative strength (BAS), forward associative strength (FAS), and theme identifiability (ID) on false memories. In Experiment 1, lists varied in BAS while controlling FAS and ID. In Experiment 2, FAS was manipulated while BAS and ID were controlled. Finally, in Experiment 3, lists varied in ID while controlling BAS and FAS. Data was analyzed using both frequentist and Bayesian analyses.

Results: We found false memories in all three experiments. Specifically, false recognition was higher in high-BAS than in low-BAS lists in Experiment 1. In Experiment 2, false recognition was higher in high-FAS than in low-FAS lists. In Experiment 3, false recognition was lower in high-ID than in low-ID lists.

Conclusions: These findings suggest that both BAS and FAS─variables that promote error-inflating processes─and ID─which promotes error-editing processes─contribute independently to the production of false memories. Splitting apart the role of these variables helps to understand the variability of false memories and to extrapolate DRM tasks to explore other cognitive domains.

错误记忆中前向/后向联想强度和主题可识别性的影响
背景:使用Deese/Roediger-McDermott范式对错误记忆进行了广泛的研究。尽管该效应具有稳健性,但结果存在广泛的可变性,这一点尚不完全清楚。方法:三个实验分别考察了后向联想强度(BAS)、前向联想强度(FAS)和主题可识别性(ID)在错误记忆中的作用。在实验1中,在控制FAS和ID的同时,列表在BAS上发生了变化。实验2控制FAS,控制BAS和ID。最后,在实验3中,在控制BAS和FAS的同时,列表的ID发生了变化。数据分析使用频率分析和贝叶斯分析。结果:我们在三个实验中都发现了错误记忆。具体而言,实验1中高bas列表的错误识别率高于低bas列表。实验2中,高fas组的错误识别率高于低fas组。在实验3中,高id列表的错误识别率低于低id列表。结论:这些发现表明,BAS和FAS(促进错误膨胀过程的变量)和ID(促进错误编辑过程的变量)都独立地促成了错误记忆的产生。分解这些变量的作用有助于理解错误记忆的可变性,并推断DRM任务以探索其他认知领域。
