Alan Baddeley is a British psychologist best known for his work on memory. He developed the Working Memory Model, which suggests that short-term memory is not a single store but consists of multiple components. These include the central executive, which manages attention, and two subsystems: the phonological loop for verbal information and the visuospatial sketchpad for visual data. Baddeley's research has significantly influenced our understanding of how we process and store information. His model has been widely used in various fields, including education and cognitive psychology, to explore how memory functions and how it can be improved.
