Learning may be defined as the encoding (storage) of knowledge and/or skills into long term memory in such a way that the knowledge and skills may be recalled and applied at a later time on demand.
Humans have a great capacity for learning and tend to spend their lives doing so. They learn not only how to walk upright, but also how to talk, read and write. Many people today learn how to drive a car, operate a microwave oven, and use a computer. Some even learn how to perform a heart transplant operation. For all of these tasks (and just about every other task you care to mention) the role, capacity and qualities of sensory memory and working memory remain effectively unchanged. The driving force behind all skilled performance is the knowledge base that has been acquired within long term memory.
