Psychological effects of reading: the role of nostalgia in re-reading favorite books.
Nostalgia evoked through various experiences (e.g., scents, music) has been shown to enhance emotional well-being and reduce social pain. We propose that reading a familiar book similarly can elicit nostalgia, and provide emotional benefits through narrative transportation beyond that of reading a new book. We tested the relationship between reading new versus familiar books, nostalgia, narrative transportation, and indices of social connectedness. Participants were randomly assigned to re-read a favorite novel, read a new novel of interest, or read a set of newspaper articles. Re-reading elicited greater nostalgia and social connectedness than reading a new novel or newspaper. Narrative transportation and nostalgia fully mediated the effect of reading condition on social connectedness. We discuss implications for our understanding homeostatic nature of nostalgia and mental transportation.
