Examine different works of art, and practice commenting on them using stream-of-consciousness dialogue. Free associating what you see in the art will help train your mind to express images as words. The better you become at translating images into words, the easier it will become to translate words into images.
Form a narrative around the work of art you are examining. Storytelling requires the use of your senses, memories and personal connections, argues researcher Abigail Housen in her essay "Eye of the Beholder." By forming a narrative you begin training your mind to associate personal experiences with visual images.
Decode the art work by examining the how, when and where of what you are seeing. By classifying the work into these basic components, you begin training your mind to visualize the basic elements of time and place. For example, by examining a painting of children on a playground in this manner, you can begin using this image to visualize such terms as school, play and recess.
