It outlines two specific contiguity principles: 1) place printed words near corresponding graphics, and 2) synchronize spoken words with corresponding graphics. It describes common violations of these principles, such as separating text from graphics or separating graphics and narration. It concludes by explaining the psychological reasons why the contiguity principle improves learning.
