Researchers from Georgia Tech, led by Yiren Ren, a doctoral student at the School of Psychology, have conducted studies that provide deeper insights into the impact of music on memory and learning. Their research reveals how music can play a crucial role in the formation and modulation of memories, with results suggesting potential therapeutic applications for mental health.

Ren, together with her mentor Thackery Brown, a cognitive neuroscientist, has published two papers that are the results of this research. The first paper deals with how familiar and predictable music can enhance the learning process, while the second focuses on the modulation of the emotional tone of pre-existing memories using music.

Music as a tool for better learning
The first part of the study investigates how familiar music can ease the process of learning and memorizing new information. Study participants learned sequences of abstract shapes while listening to different types of music. Results showed that music which was familiar and rhythmically predictable to participants improved learning. The brain creates a structured framework for new information, allowing for faster recall and easier remembrance.

Ren utilized her skills as a musician and composer to create musical compositions used in the study. Participants remembered sequences more successfully when listening to pieces with familiar musical patterns, whereas irregular compositions hindered learning. This research opens new possibilities for using music as a mnemonic tool, potentially beneficial in educational methods.

Music and modulation of emotions in memories
The second part of the research focuses on how music can alter the emotional tone of memories that are already stored in the brain. In collaboration with scientists from the University of Colorado, Ren and Brown investigated whether music with a strong emotional impact could change the way we recall past events.

In the experiment, participants listened to movie soundtracks while recalling difficult moments from their past. Results showed that participants, under the influence of music, were able to alter the emotional tone of their memories. The next day, even without the music, their emotional reaction to the memories remained in line with the music they had listened to the day before.

Practical applications in therapy
This research has significant implications for therapeutic applications, especially in working with patients who suffer from mood disorders such as post-traumatic stress disorder (PTSD) or depression. Music could be used to modulate negative emotional memories, helping patients to reinterpret and reduce the intensity of negative emotions associated with certain events.

Ren, who plans to continue her research through a postdoctoral position, aims to develop musical therapies not only for individuals with mood disorders but also for the elderly and those with dementia. By studying the neurological mechanisms that allow music to influence human behavior, she hopes to open new areas of application in rehabilitation and therapy.

Her future research could provide valuable evidence to support the development of musical interventions for mental health and cognitive functions, enabling better control over the emotional tone of memories and improving the quality of life for patients.

Science & tech desk

Our Science and Technology Editorial Desk was born from a long-standing passion for exploring, interpreting, and bringing complex topics closer to everyday readers. It is written by employees and volunteers who have followed the development of science and technological innovation for decades, from laboratory discoveries to solutions that change daily life. Although we write in the plural, every article is authored by a real person with extensive editorial and journalistic experience, and deep respect for facts and verifiable information.

Our editorial team bases its work on the belief that science is strongest when it is accessible to everyone. That is why we strive for clarity, precision, and readability, without oversimplifying in a way that would compromise the quality of the content. We often spend hours studying research papers, technical documents, and expert sources in order to present each topic in a way that will interest rather than burden the reader. In every article, we aim to connect scientific insights with real life, showing how ideas from research centres, universities, and technology labs shape the world around us.

Our long experience in journalism allows us to recognize what is truly important for the reader, whether it is progress in artificial intelligence, medical breakthroughs, energy solutions, space missions, or devices that enter our everyday lives before we even imagine their possibilities. Our view of technology is not purely technical; we are also interested in the human stories behind major advances – researchers who spend years completing projects, engineers who turn ideas into functional systems, and visionaries who push the boundaries of what is possible.

A strong sense of responsibility guides our work as well. We want readers to trust the information we provide, so we verify sources, compare data, and avoid rushing to publish when something is not fully clear. Trust is built more slowly than news is written, but we believe that only such journalism has lasting value.

To us, technology is more than devices, and science is more than theory. These are fields that drive progress, shape society, and create new opportunities for everyone who wants to understand how the world works today and where it is heading tomorrow. That is why we approach every topic with seriousness but also with curiosity, because curiosity opens the door to the best stories.

Our mission is to bring readers closer to a world that is changing faster than ever before, with the conviction that quality journalism can be a bridge between experts, innovators, and all those who want to understand what happens behind the headlines. In this we see our true task: to transform the complex into the understandable, the distant into the familiar, and the unknown into the inspiring.
