Mood, dissociation and false memories using the Deese-Roediger-McDermott procedure

Area of Science:

• Cognitive Psychology
• Memory Research
• Psychology of Emotion

Background:

• Investigating factors influencing false memory susceptibility.
• Examining the role of transient states, such as mood, in memory distortion.
• Understanding individual differences in memory accuracy.

Purpose of the Study:

• To determine if dissociation and mood influence false memory generation using the Deese-Roediger-McDermott (DRM) procedure.
• To explore the relationship between dissociation, mood states, and false memory occurrence.
• To investigate how task demands moderate the effect of mood on false memories.

Main Methods:

• Utilized the Deese-Roediger-McDermott (DRM) procedure to elicit false memories.
• Assessed participants' scores on a dissociation measure.
• Manipulated participants' mood states and varied task demands for memory recall.

Main Results:

• Dissociation was not associated with false memories, contrary to previous findings with different procedures.
• The DRM procedure's dual-process requirement (lure generation and source monitoring) may explain the lack of dissociation association.
• Mood influenced false memories, with negative moods increasing false memories under high recall demands and positive moods under lenient recall demands (mood-as-input hypothesis).

Conclusions:

• Dissociation appears specifically linked to source monitoring errors, not necessarily all types of false memories.
• Mood's impact on false memories is context-dependent, influenced by task instructions and cognitive demands.
• Findings contribute to understanding memory fallibility and the interplay between emotion, cognition, and task context.
