Background
Performing dual tasks, such as making eye movements or playing Tetris, while recalling a negative or traumatic emotional memory would reduce the emotional charge associated with that memory.
The theories of Memory Consolidation/Reconsolidation (M-C/R) and Working Memory (WM) may jointly contribute to understanding these effects.
Objectives
To review the current state of studies evaluating the effects of dual tasks on the vividness and emotionality of negative and negative emotions
Traumatic emotional memories and experimentally induced aversive stimuli.
To identify and describe studies using methodologies that articulate (MT) and (C/R-M) theories.
Method
A systematic review based on PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analysis) guidelines was conducted INPLASY202440065).
- Databases
Pubmed, PsycINFO.
- Inclusion criteria
Quantitative studies examining the effects of dual tasks on the emotionality and vividness of aversive, traumatic, or experimentally induced memories, published between 2000 and 2024,
- Human model,
- Academic and scientific journal articles (clinical trials, experimental laboratory studies, RCTs, etc,)
- English or French.
Conclusion
The effects of dual tasks on reducing the emotional charge associated with negative or traumatic memories are well established. However, it is not certain that articulating the (M-C/R) and (WM) theories is sufficient to account for the processes underlying their effectiveness. Further research is therefore needed to identify the processes involved.
Background and objectives
Background
Administration of dual tasks i.e. making eye movements or playing the Tetris game during the recall of a negative or traumatic emotional memory would reduce the emotional charge associated with this memory.
The theories of Memory Consolidation/Reconsolidation (M-C/R) and Working Memory (WM) can jointly contribute to their understanding.
Objectives
To review the current state of studies evaluating the effects of dual tasks on the vividness and emotionality of negative and
Traumatic emotional memories, and on experimentally induced aversive stimuli.
To identify and describe studies using methodologies that articulate (MT) and (C/R-M) theories.

A systematic review based on PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analysis) guidelines was carried out INPLASY202440065).

Conclusion
The effects of the dual task on reducing the emotional charge associated with negative or traumatic memories are well established. However, it is not certain that the articulation of the (M-C/R) and (WM) theories is sufficient to justify the processes explaining their effectiveness. Further research is therefore needed to identify the processes involved.
