Our perception of time as a continuous flow contrasts with the way our memories compartmentalize into distinct episodes. Science is just beginning to unravel how emotions shape this process. UCLA psychologists recently uncovered a significant clue: fluctuating emotions, induced by music, play a pivotal role in forming enduring and separate memories.
MUSIC AS AN EMOTIONAL CATALYST
Published in Nature Communications, the study manipulated volunteers’ emotions using music while they performed simple tasks on a computer. Emotion dynamics, the researchers found, transformed neutral experiences into memorable events.
CREATING BOUNDARIES BETWEEN MEMORIES
Lead author Mason McClay highlights that emotional changes spurred by music delineated boundaries between episodes, aiding people in remembering what they saw and when they saw it. The study foresees therapeutic potential for PTSD and depression.
TUG OF WAR IN MEMORY FORMATION
Memory formation involves two processes over time: integration, linking memories into episodes, and expansion, separating each memory as experiences fade. This constant interplay helps shape distinct and meaningful memories, aiding understanding and retention of information.
EMOTIONS: MEMORY’S ORGANIZATIONAL TOOL
Corresponding author David Clewett likens emotions to boxes for long-term memory storage, making memories more accessible and organized. Emotional changes act as effective organizers, facilitating better recall of information.
The study suggests parallels between emotional experiences in Taylor Swift’s “Eras Tour” and the research findings. Concerts often contain emotionally charged chapters that linger in memory.
MUSIC-INDUCED EMOTIONAL RESPONSES
Using specially crafted music to evoke varied emotions, participants imagined narratives for neutral images while monitoring their emotional reactions. Post-task distraction and image recall revealed that emotional shifts affected memory, separating and expanding the mental distance between new memories.
DIRECTION OF EMOTIONAL SHIFTS
Shifts toward more positive emotions resulted in better memory integration and recall of sequential items, while shifts toward negative emotions expanded the mental distance between memories.
MUSIC’S THERAPEUTIC POTENTIAL
The study highlights music’s potential as an intervention tool, suggesting emotionally dynamic music could directly treat memory issues prevalent in disorders like PTSD. Positive emotions, particularly, could help fuse and re-integrate fragmented memories.
AIDING PTSD RECOVERY
The team believes employing positive emotions, possibly through music, could help those with PTSD reintegrate traumatic memories, preventing negative emotions from intruding into daily life
