# Emotional impact of using different sensory modalities for autobiographical activation: a systematic review and meta-analysis

## TL;DR

This paper reviews and analyzes how different memory-based interventions affect emotions, aiming to find the most effective methods for mood manipulation.

## Contribution

The study provides the first systematic review and meta-analysis of memory-based interventions for emotional activation.

## Key findings

- Current evidence on memory-based interventions is fragmented and lacks a unified synthesis.
- The study identifies a need for standardized protocols to better understand and apply these interventions.

## Abstract

To the best of our knowledge, no previous work has synthesized the efficacy of MIPs based on the retrieval of AMs in relation to a wide range of both basic and complex emotions. This gap highlights the need to better understand how these interventions influence emotional states.

Accordingly, we conducted a systematic review of the literature and, when data were sufficient, a meta-analysis of pre-post changes in affective state. Our aim was to identify the most effective procedures for manipulating mood within empirical studies, and to develop a coherent framework to organize and interpret the efficacy of these types of MIPs, providing a foundation for future research.

The existing evidence is fragmented across heterogeneous protocols and lacks a unified quantitative synthesis. This fragmentation underscores the necessity of a systematic review and meta-analysis, which the present article undertakes to address.

Furthermore, we consider the growing interest in the field of “memory therapy”, given its clinical benefits in helping individuals access past events and allowing them to relive experiences and their associated emotions. This area holds promise for enhancing emotional regulation and therapeutic outcomes.
