Brain stores and process information based on the following principles
Photographic: Brain has enormous capacity to remember pictures and images. It is much easier to remember a picture than to remember long lines of text.
Keywords: Brain stores information based on the abstraction principle. After reading long paragraph, brain condenses this information and stores keywords or headlines which abstracts the content in the paragraph.
Stories: It is more important than facts for remembering ideas. Stories capture facts in many different context and aids in retrieving and correlating with many other aspects. “Humans are not ideally set up to understand logic; they are ideally set up to understand stories.” –Roger C. Schank, cognitive scientist
Associations:Brains links different subjects together to create a pattern. New information feed to the brain will get associated with existing pattern already formed based on the previous information fed to it.
Context: Information fed into the brain is stored based on the context. For example ‘laptop’ is stored in brain with contexts such as when it is bought, who bought it, How much, Where it is bought,etc. Once it is stored in brain it can be retrieved with one of more context values as input.
