Item-specific encoding reduces false recognition of homograph and implicit mediated critical lures

ABSTRACT We evaluated the effects of item-specific and relational encoding instructions on false recognition for critical lures that originated from homograph and mediated study lists. Homograph lists contained list items that were taken from two meanings of the same critical lure (e.g., autumn, trip, harvest, stumble; for fall) which disrupted thematic/gist consistency of the list. Mediated lists contained unrelated list items (e.g., slippery, spicy, vent, sleigh) that were indirectly related to a critical lure (e.g., cold), through a set of non-presented mediators (e.g., wet, hot, air, snow), and had no thematic/gist consistency. In two experiments, item-specific and relational encoding improved correct recognition relative to a read-only control task, but only item-specific encoding reduced false recognition of critical lures. Signal-detection analyses indicated that the item-specific reduction increased test-based monitoring. The item-specific reduction for homograph and mediated critical lures is consistent with the activation-monitoring framework given gist-based processes are reduced or eliminated on these list types.

自我参照加工与情绪性诱词的关联性错误记忆<br>The Research of Self-Reference Effect on the Associative False Memory

本研究结合DRM错误记忆范式(Deese-Roediger-McDermott paradigm)和自我参照效应的研究范式，以女大学生为被试，采用口头造句任务考察了关键诱词的情绪效价和不同参照加工条件对关联性错误记忆的影响。研究结果表明：1) 诱词的情绪效价影响了关联性错误记忆，表现为正性诱词比中性和负性诱词显示了更高的错误再认率；2) 相对于他人参照，自我参照加工具有诱发更强烈错误记忆的趋势。 The present study investigated how self-referential process influenced the associative false mem- ory for affective lures by combining the research paradigm of DRM with that of the self-reference effect. The following conclusions were drawn from the study: 1) The valence of the critical lures influenced the false memory. That is, the false recognition rate of the positive lures was higher than negative lures and neutral lures. 2) Compared to the other-referential processing condition, the recognition of critical lures has a ten- dency to increase under the self-referential processing condition.

False recognition in women with a history of childhood emotional neglect and diagnose of recurrent major depression

While previous research has suggested that adults with a history of childhood sexual abuse may be more prone to produce false memories, little is known about the consequences of childhood neglect on basic memory processes. For this reason, the authors investigated how a group of women with a history of childhood emotional neglect (CEN) and diagnosed with recurrent Major Depressive Disorder (MDD) performed on the Deese-Roediger-McDermott paradigm in comparison to control groups. The results indicated that women with MDD and CEN were actually less prone to produce false memories relative to both women with MDD but no CEN and healthy women without MDD and any form of childhood maltreatment. These findings were explained in terms of the inability to extract/retrieve gist memories that support false recognition of critical lures, an explanation that seems to fit well with emerging MRI findings linking childhood neglect to reduced volume of brain regions associated to memory function.

Mood-congruent false memories in the DRM paradigm

This study investigated the creation of mood-congruent false memories within the Deese–Roediger–McDermott (DRM) paradigm using recall and recognition of critical lures as performance measures. Participants (n=93) were randomly assigned to three mood-induction conditions (positive, negative and control) and were presented with positive, negative and neutral DRM word lists in audio form. We predicted that intrusion errors of the critical lures would be higher in the mood-congruent conditions. Results confirmed this prediction and extended previous DRM research by showing that already high false memory rates were increased when the valence of the lures matched the mood-induction condition. Furthermore, participants made more “remember” judgements for the emotion critical lures in their mood-congruent conditions. Discussion draws on spreading activation explanations of DRM findings, and considers how moods could increase activation of non-presented information.

Can test list context manipulations improve recognition accuracy in the DRM paradigm?

Only test-based manipulations can be used to help people distinguish accurate from false memories once events have been encoded. In two experiments we examined how the type of studied words (weak vs strong associates, or less vs more memorable associates) and nonstudied lure words (related vs unrelated lures) on the test list affect recognition accuracy in the Deese-Roediger-McDermott paradigm. False recognition of critical lures decreased substantially in the related-lure context, but so did correct recognition of studied words. False recognition was little affected by the studied-word manipulations. In general, participants claimed to recognise critical lures as often as weak associates or less memorable studied words but less often than either strong associates or more memorable studied words. The test-list context affected how participants classified their recognition experiences but it did not systematically change their overall memory accuracy.

False memories in children and adults: Age, distinctiveness, and subjective experience.

This study investigated developmental trends associated with the Deese/Roediger-McDermott false-memory effect, the role of distinctive information in false-memory formation, and participants' subjective experience of true and false memories. Children (5- and 7-year-olds) and adults studied lists of semantically associated words. Half of the participants studied words alone, and half studied words accompanied by pictures. There were significant age differences in recall (5-year-olds evinced more false memories than did adults) but not in recognition of critical lures. Distinctive information reduced false memory for all age groups. Younger children provided with distinctive information, and older children and adults regardless of whether they viewed distinctive information, expressed higher levels of confidence in true than in false memories. Source attributions did not significantly differ between true and false memories. Implications for theories of false memory and memory development are discussed.

The impersistence of false memory persistence

When subjects study lists of thematically related words they sometimes falsely recognise non-presented words related to the theme. The gist extraction account of these findings provided by fuzzy trace theory suggests that false recognition should decline substantially more slowly than true recognition across a delay. In two experiments we demonstrated that corrected recognition of targets and critical lures can decrease by equivalent amounts across a 48-hour delay. However the results for uncorrected recognition were mixed. In Experiment 1 we found evidence that uncorrected recognition of targets declined more rapidly than uncorrected recognition of critical lures. In Experiment 2, we found evidence that uncorrected recognition of targets and critical lures declined at equivalent rates. Results are discussed in terms of their implications for fuzzy trace and source monitoring accounts of false memories.
