Based on the existing research, this study explores the effect of image coding processing level and word presentation on false memory under the DRM paradigm. A two-factor completely randomized experimental design of 2 (image coding processing level: deep processing, shallow processing) × 2 (presentation method: group presentation, random presentation) was used for the study. 120 undergraduates were recruited for the experiment, with 30 students in each experimental group. This study can draw the following conclusions: (1) the level of image coding processing has no significant effect on false memory; (2) word presentation method has an impact on false memory, and the false memory rate under group presentation is higher than that in random presentation; (3) The level of representational coding processing and presentation methods jointly affect false memory. Under the condition of group presentation, the false memory rate of the deep processing group is higher than that of the shallow processing group; The false memory rate of the group presentation group was greater than that of the random presentation group. This suggests that learners may group learning materials to improve learning efficiency in the process of learning and memory, and discriminate learning materials with similar semantics to reduce the occurrence of false memory and achieve better learning and memory effects.
