Visual literacy was originally defined as a set of visual competencies or cognitive skills and strategies one needs to make sense of visual images. These visual competencies were seen as universal cognitive abilities that were used for understanding visual images regardless of the contexts of production, reception, and dissemination. More contemporary definitions suggest visual literacy is a contextualized, social practice as much as an individualized, cognitively based set of competencies. Visual literacy is more aptly defined as a process of generating meanings in transaction with multimodal ensembles that include written text, visual images, and design elements from a variety of perspectives to meet the requirements of particular social contexts. Theories of visual literacy and associated research and pedagogy draw from a wide range of disciplines including art history, semiotics, media and cultural studies, communication studies, visual ethnography and anthropology, social semiotics, new literacies studies, cognitive psychology, and critical theory. Understanding the various theories, research methodologies, and pedagogical approaches to visual literacy requires an investigation into how the various paradigm shifts that have occurred in the social sciences have affected this field of study. Cognitive, linguistic, sociocultural, multimodal, and postmodern “turns” in the social sciences each bring different theories, perspectives, and approaches to the field of visual literacy. Visual literacy now incorporates sociocultural, semiotic, critical, and multimodal perspectives to understand the meaning potential of the visual and verbal ensembles encountered in social environments.
