Long-term memory (LTM) has virtually unlimited capacity and can store information for a lifetime. It includes declarative memory (explicit: episodic and semantic) and non-declarative memory (implicit: procedural, priming). Sensory memory lasts milliseconds; short-term memory holds about 7±2 items for 15–30 seconds; working memory is the active, limited-capacity system for immediate cognitive tasks.
