Dual coding

Dual coding is the idea that we process and remember information better when it is encoded in two ways: verbally (words, language) and nonverbally (e.g. mental imagery). Allan Paivio’s dual coding theory proposes that the mind has separate but linked systems for verbal and image-based representation; when you store something as both a word and a mental picture, you create two retrieval paths and often improve retention and recall. The benefit is especially clear for concrete, imageable material. So visual imagery (or other sensory imagery) can add a second memory pathway alongside verbal rehearsal—which is one reason imagery-based study strategies can support learning and recall. The Imagination Index measures your vividness in each sense so you can see which channels might support your own encoding and recall.
