How sound and smell are tied to learning, and the connection to sleep | Matthew Walker
Context-dependent memory, a type of memory that occurs when contextual cues facilitate memory recall, is based on the premise that during memory storage, contextual information, such as sounds, smells, or tastes, are also stored. Retrieval of the memories is enhanced when exposed to the context. Although smells are among the strongest cues in inducing and retrieving memories, sounds can also provide strong stimuli for learning. In this clip, Dr. Matthew Walker describes how sound and smell cues played during learning and subsequent sleep can enhance memory formation and retrieval.
