Memory is defined as ‘learning that has persisted over time — information that has been stored and, in many cases can be recalled’. It helps make us who we are, some memories being processed automatically like our ability to walk, some being stored differently. It is these that form a chain connecting our past to our present.
We can access memories in 3 ways; recalling them directly, such as remembering the answer to a question, we can recognise something when presented with items previously learned, such as a multiple choice test, or we can relearn information, which takes less time than first learning and is more like revising for an exam.
This video takes you through how the brain creates and stores memories, and why some stick and some don’t.
