The proust effect: Scents, food, and nostalgia
Abstract
Autobiographical memories activated by the senses, particularly smell and taste, can be among the most potent and influential, an experience labelled the Proust Effect. Contemporary research has helped to explain the physiological, neurological, and psychological reasons underlying this phenomenon. Nostalgic memories triggered by taste and smell are especially self-relevant, arousing, and familiar. These memories have an even more positive emotional profile than nostalgic memories elicited by other means, with individuals reporting lower levels of negative or ambivalent emotions. Scent-evoked and food-evoked nostalgia also confer numerous psychological benefits, including enhanced self-esteem, feelings of social connectedness, and deeper meaning in life. Such memories might be harnessed in clinical or other settings.
