According to psychologist, psychotherapist and hypnotherapist Dr Jonathan Pointer, the appeal in returning to treasured TV, films, music, books, video games, sporting moments, and even food, lies in the connection between emotion and memory. “Emotions and memories are linked; emotions reactivate memories, and memories reactivate emotions. So nostalgic reminiscence, when we create an emotional response through reminiscing on past events, is an easy way to re-experience an emotion attached to a particular memory. This can be aided by retrieval cues, such as smells, sights, sounds, from our past,” he says.
