Imagine slipping on a virtual reality headset and—just for a moment—seeing a child’s face staring back at you… but it’s your face. The same eyes. The same smile. The same freckles you had at age six. What happens next might surprise you: a flood of vivid, once-forgotten memories. Recent research into body illusion therapy and the enfacement illusion shows how self-perception can access inaccessible childhood memories, opening up new possibilities for therapy, identity understanding, and the science of memory.
Understanding Childhood Memory Recall
Childhood memory recall, or the ability to recollect personal experiences from early life, is more than just a nostalgic exercise—it’s central to forming who we are and for our mental health. These memories, called autobiographical memories, contribute to our sense of who we are. From understanding our relationships to dealing with life changes, these recollections play a crucial role.
But, most people find their early memories frustratingly fragmented or entirely absent. This common thing is known as childhood amnesia. By the time we reach adulthood, memories before the age of about three or four are typically inaccessible. That’s not due to laziness or lack of clear experiences, but rather to the way the brain grows during early childhood.
During infancy and early childhood, the brain’s memory systems are still under construction. The hippocampus, responsible for forming and keeping long-term memories, is immature in children. And then, the medial prefrontal cortex—which helps put together emotional and contextual information—is also still growing.
Moreover, the way we save memories shifts over time. Early memories are often stored without the full language or story structures we later use to get them back. This makes them especially hard to find as we grow older. And then, our internal ways of thinking change, filtering out experiences we see as less important based on what adults care about.
But what if there were a way to bypass that adult mental model? A way to reconnect with an earlier version of ourselves—triggering the context our brain needs to get to those early years?
What Is the Enfacement Illusion?
The enfacement illusion is one of the most powerful examples of how adaptable our self-perception truly is. At its core, the enfacement illusion is a multi-sensory psychological event where people start to see another face as their own. This happens especially when sensory cues—such as what they see and what they feel—are perfectly matched.
Here’s how it typically works: participants wear a virtual reality headset and see another face—often either generic or slightly changed to look like theirs—on a digital avatar. At the same time, they receive touch on their own face, timed and placed to match what they see. For instance, if the avatar is touched on the left cheek, the participant also feels a touch in the same place at the same time.
This artificial sensory match tricks the brain into adding the virtual face into its self-model. Brain scans and studies on behavior have shown that people start to feel they are the avatar, even taking on emotional and behavioral cues that fit with the virtual person.
Crucially, the key to the enfacement illusion is that things must line up. When touch, movement, and visual perception are all matched in real-time, the brain does not fight the illusion—it adapts. The line between self and other becomes blurry. When the “other” looks like our younger self, it creates a deep identity connection.
Childlike Self-Representation and Memory Access
An exciting part of the enfacement illusion is using it with childlike avatars. In a first-of-its-kind study by Ludersdorfer and colleagues (2024), researchers wondered: what if the virtual face wasn’t just anyone—but you, as a child?
Using facial-aging software and machine learning algorithms, researchers made childlike versions of adult faces based on the adult facial features. These avatars were placed within immersive VR settings, and participants were guided through an interaction where the child-avatar was touched and moved at the same time as their own actions and feelings.
The effects were remarkable.
Participants who took on their child selves through virtual reality had significantly improved childhood memory recall. Not only did they call back more memories, but the memories they called back were also more vivid, emotionally strong, and specific. The childlike body seemed to work like a key—allowing access to childhood memories that were previously out of reach.
These findings marked the first time researchers successfully used self-related body illusion therapy to measurably improve childhood memory recall. This is very important, especially for people where memory access is limited or important for therapy.
Mirror Neurons and Multisensory Integration in Self-Recognition
Behind the enfacement illusion are the complex ways our senses combine and how mirror neurons work. These systems make human empathy, imitation, and self-recognition possible.
Mirror neurons—initially found in the premotor cortex—become active when a person does an action and when they see someone else doing the same action. This mirroring is thought to be basic for forming a concept of the self in relation to others. When this system is active through matched interaction with a virtual avatar, it helps build an illusion of having that body.
Multisensory integration plays another part. The brain constantly combines information from different senses to form a clear view of reality. Sight, touch, proprioception (sense of body position), and even sounds are combined to decide what is seen as “real” and what belongs to the self.
In the enfacement illusion, when the sensory inputs from the virtual child’s face match those of the real adult body’s feelings, the sense-of-self stretches to take in the new input. It’s not just a mask; it becomes a temporary picture of the body schema—a brain map of the physical self.
By reacquainting the neural body map with its earlier form, the brain is prompted to get to memories stored with that form—essentially rewriting the cues needed to get back early memories.
Neuroscience Behind Body Illusions and Memory
Brain scan studies also show the effectiveness of the enfacement illusion in changing self-perception and memory processes. Functional MRI (fMRI) shows increased activity in several brain regions during and after using childlike self-representation.
Key brain regions affected are:
- Temporoparietal Junction (TPJ): Involved in body ownership, where one is, and taking another’s view.
- Anterior Insula: Helps with emotional awareness and interoception (sense of the internal state of the body).
- Medial Prefrontal Cortex: Linked to self-relevant thought, planning, and autobiographical memory.
- Hippocampus: Important for saving and calling back episodic memories.
When participants identified with their childlike avatars, these regions became more active, especially those involved in getting memories back and processing emotions. This gives strong support to the idea of embodied cognition: that our physical self directly tells us and shapes how we think, call back, and feel.
These findings fit with other research on memory-mediated self-processing. They show that how we see ourselves and what we call back isn’t a coincidence—it’s a closed loop system where memory affects self-image, and self-image can, in turn, reawaken memory.
Therapeutic Implications: Could Body Illusion Therapy Aid in Trauma and Memory Disorders?
The practical uses of this science are just beginning to appear—but they could be very impactful.
Body illusion therapy, which uses controlled changes of bodily experience to improve emotional or neurological conditions, is already used in innovative ways. VR-based therapies exist for treating:
- Phantom limb pain
- Eating disorders, including body dysmorphia
- Post-traumatic stress disorder (PTSD)
- Stroke rehabilitation and motor recovery
- Social anxiety and self-image issues
Now, researchers are looking at how these techniques might help with memory-related disorders.
For people with childhood trauma and dissociative disorders, getting to early memories can be both healing and hard. Body illusion treatments could offer a controlled, gentle reentry into early-life identity, without stressing the nervous system. For brain-wasting conditions like Alzheimer’s disease, creating a link with earlier stages of the self could strengthen brain pathways by reactivating memory—possibly slowing decline.
Of course, these are hopeful uses; the field is still being actively researched. But the early data shows huge potential for enfacement illusions to reshape not just what we know—but who we know ourselves to be.
The Ethics and Limitations of Induced Memory Retrieval
As the power of body illusion therapy and childhood memory recall becomes clear, so do the ethical worries.
Memory is built up, not simply played back. When we think back, we don’t just pull up a video of our past—we rebuild it. We add partial clues with guesses and emotion. The risk, then, in using techniques like the enfacement illusion, is creating situations that are easy for suggestion.
False memories could be made if the process isn’t managed with care. Especially in therapy settings—where at-risk clients look at traumatic or key life events—this could lead to emotional upset or wrong facts being misused.
To work against these risks, strict ethical rules must be put in place:
- Professional clinician oversight
- Client protections and basic rules
- Clear explanation of the therapy as being for finding things out
- Use of confirmed memory anchors when possible
The technique must never be used to find truth—instead, it should be a self-discovery tool. This difference could mean everything for patient results and whether it is seen as right.
Building a Future of Memory-Enhanced Tools
Looking ahead, the mix of neuroscience, psychology, and immersive technology is set to change how we interact with our identity over time.
As virtual reality becomes easier to get, developers might create platforms made not just for fun, but for emotional growth, educational progress, and self-discovery. Imagine:
- VR memory-training programs for seniors
- Self-regulation tools for teenagers handling identity crises
- Tailored therapy packages for working through childhood trauma
- AI-driven memory journals that change based on your past experiences
These advancements will only work if built on solid science and ethical foundations. Just as importantly, working together across different fields—between neuroscientists, programmers, clinicians, and ethicists—will be essential to use this potential responsibly.
Everyday Applications: Can This Help Us Call Back What Matters?
You don’t need a full VR setup to start looking at your relationship with your past. Even simple methods of guided visualization, photo therapy, or journaling across different life stages can awaken deeply held memories.
For educators, parents, and counselors, simple exercises like drawing yourself at age eight, writing letters to a younger self, or viewing childhood pictures through immersive media can be powerful tools for empathy and self-reflection.
In a world more and more focused on getting things done and moving forward, reconnecting with our younger selves can provide grounding, clarity, and emotional insight. Whether you’re a therapist, a teacher, or someone simply trying to understand themselves better—the idea that our present self can use the wisdom and wonder of our past is both empowering and healing.
How to Stay Curious: Learning About the Inner Workings of Your Mind
If you looked in the mirror and saw your 8-year-old self, what memory would resurface?
The study of childhood memory recall through body illusion therapy—especially via the enfacement illusion—is still in early days. But its power lies in the invitation it offers: to revisit ourselves with openness, curiosity, and care. While memories may fade, the self remains deep and complex, waiting to be rediscovered.
