The smell of freshly baked cookies and swimming pools can bring back fond memories of childhood. Other, often less pleasant, odors can trigger memories we’d rather forget. And studies have shown that our sense of smell is more effective for memory recall than sight and sound. One reason for this is that the body simply has more scent receptors than it does for the other senses. But sight, sound, and touch all play a role in our ability to access memories.
Although research from the University of Iowa found that we don’t remember what we hear quite as well as what we see or touch, aural learning remains among the seven learning styles, which would suggest that some people process, or even excel at processing, sound better than others.
