Allan Paivio is a Canadian psychologist best known for his work in cognitive psychology and educational psychology. He developed the Dual Coding Theory, which suggests that information is processed in two distinct systems: one for verbal information and another for visual information. This theory has significant implications for learning and memory, emphasizing the importance of using both words and images to enhance understanding. Paivio's research has influenced various fields, including education and communication. His findings support the idea that combining verbal and visual materials can improve retention and recall. Throughout his career, he has published numerous articles and books, contributing to the understanding of how people learn and remember information.
