Researchers at Anglia Ruskin University have discovered that changing how people perceive their own bodies can enhance access to long-forgotten childhood memories. The study used the ‘enfacement illusion’, a technique in which participants view a video of their own face that moves in real time with them, creating the feeling that the face on the screen is their own.

In this experiment, 50 adults either saw their normal adult face (control group) or a digitally altered version that looked like a younger, childlike version of themselves. After experiencing the illusion, participants completed an autobiographical memory interview. They were asked to recall events from both the previous year and from early childhood. Researchers measured how many episodic details the participants reported—these are the sensory, emotional, and contextual elements that allow us to mentally ‘relive’ an experience.

The results were striking: those who saw the younger version of themselves recalled significantly more detailed childhood memories than those who saw their adult face. This suggests that the brain stores memories alongside internal cues about the body. By reintroducing bodily cues that resemble one’s childhood self, the brain may find it easier to access older, harder-to-reach memories.

The findings support the idea that autobiographical memory is not purely cognitive but deeply tied to our sense of the physical self. This links to theories of forgetting—particularly the notion that memory retrieval depends on cues that match the original encoding context. The researchers propose that, in the future, such illusions might help people with memory difficulties or potentially provide new methods to explore memories from very early life.
