The elements of a mind map are created relative to the importance of the ideas or concepts, and are classified into groupings, branches, sub-branches, or areas, with a goal of representing connections between the information.
A mind map is a graphical method of taking notes. It radiates from the center and uses lines, words, symbols, images and color according to simple, brain-friendly concepts. It is a different way of thinking compared to the typical linear approach of writing an outline. It allows ideas to flow onto the page from every angle. You can worry about organizing them at a later time.
Pictorial or graphical methods for recording knowledge have been used for centuries in brainstorming and visual thinking exercises by educators, psychologists, engineers, and others. British psychology author Tony Buzan has made a claim to the origin of the Mind Map.
He argues that ‘traditional’ outlines require that the reader scans the information from left to right and top to bottom, whilst the brain’s natural preference is to scan the entire page in a non-linear fashion. Buzan also uses widespread assumptions about the cerebral hemispheres in order to promote the exclusive use of mind mapping over other forms of note making.
