Picture Superiority Effect

According to the picture superiority effect, pictures are remembered better than words—especially when people are casually exposed to the information and the exposure is for a very limited time. When information recall is measured just after exposure to a series of pictures or a series of words, the recall for pictures and words is about equal. The picture superiority effect, however, applies when the time after exposure is more than 30 seconds, according to research cited in Universal Principles of Design (Rockport Publishers). “Use the picture superiority effect to improve the recognition and recall of key information. Use pictures and words together, and ensure that they reinforce the same information for optimal effect,” say authors Lidwell, Holden, and Butler. The effect is strongest when the pictures represent common, concrete things.
