In this post, we’ll unpack all you need to know about memory, defining exactly what it is, its evolutionary role, the science, short-term versus long-term, how to maximise retention and recall and more.
What Is Memory?
Memory refers to the psychological process that the brain uses to encode, store and retrieve information over time.
The Evolutionary Perspective
From an evolutionary perspective, memory evolved as a survival mechanism by allowing humans to learn from past experiences, recognise patterns and also make more informed decisions.
Short-Term Versus Long-Term
Short-term (also known as working) memory is limited and is designed to temporarily store information for the short-term.
Long-term (also known as procedural) memory is unlimited and is designed to permanently store information for the long-term.
The Science
Memory is determined by association, emotion and repetition.
Association links new knowledge with existing knowledge and activates specific neural pathways. Both emotion and repetition strengthen neural pathways, thus improving retention.
How To Maximise Retention & Recall
There are two keys to maximising retention and recall of information. Firstly, connect new information to emotional experiences. Secondly, reinforce information through spaced repetition.
Summary (TL;DR)
Memory is the process that the brain uses to encode, store and retrieve information over time.
It evolved to allow humans to learn from past experiences, recognise patterns and also make more informed decisions.
It is determined by association which links new knowledge with existing knowledge and activates specific neural pathways and emotion and repetition which strengthen neural pathways.
