Visual Literacy is a field that encompasses a variety of theoretical constructs and practical considerations relating to communicating with visual signs. The theoretical constructs that influence visual communication primarily fall into two closely interrelated categories: those that relate to the individuals involved in the communication process, and those that relate to the visual signs. The first category includes visual perception, hemispheric processes, mental imagery, and cognitive styles. The second category includes sign systems, visual languaging, image variables, and image analysis. The practical considerations include teaching about visual communication, relationships between visual and verbal learning, audiovisual materials in classroom teaching, and influences of media, especially television. Twenty-nine references are listed. (Author/LLS)
