a study of smell and memory

A Viking museum in England decided to replicate more than just the sights and sounds of the life of the Vikings. They also created an experience.to remember with the help of smells, including smells of a leather-making shop and the salty ocean. In one study of smell and memory, 50 participants who had visited the museum were asked to describe the museum five years later. Researchers were amazed to discover that when the participants were exposed to identical smells to the ones used in the museum, they were shown to have remembered 20 percent more of the museum's contents. Since the study was published, many other museums have considered including smells in their exhibits
