New memories refer to recently acquired information or experiences that are stored in our brains for later retrieval. These memories can be short-term (temporary) or long-term (more permanent).
Encoding refers to how incoming information is processed by our brains before being stored as a memory. It involves transforming information into a format suitable for storage.
Retrieval is the process of accessing stored memories from our brain. It involves bringing stored information back into consciousness for use in the present moment.
