The encoding of information, its storage and retention, and subsequent retrieval. The information can range from stimuli, events and images through to ideas. Many different memory systems have been identified such as perceptual memory, working memory and the distinctions between long-term memory (of which perceptual memory is a part), sensory and short-term memory (of which working memory is a part), declarative and procedural memory, episodic and semantic memory, as well as explicit and implicit memory. There are some overlaps in meaning between these different systems.
