Memory drawings are part of the methods of art educational therapy. Memory drawings can involve images on their own but words can also be connected to them in diverse ways. Memory drawings aid individuals in better memorizing various facts related to their studies, for example spelling, translations of foreign words and facts connected to academic subjects. A quantitative study conducted by Unnur Óttarsdóttir showed that, over long time periods, it is generally five times easier to recall drawn images of words than written words. In addition, along with aiding memory retention, memory drawings can facilitate the processing of difficult emotions and life experiences in the same way that the process of art-making aids mental health within art therapy.
