Baddeley and Hitch are renowned psychologists known for their work on the model of working memory. In 1974, they proposed a multi-component model that includes the central executive, which manages attention and coordinates information, and two subsystems: the phonological loop for verbal information and the visuospatial sketchpad for visual and spatial data. Their model challenged the earlier view of memory as a single store, emphasizing that working memory is an active process. This framework has significantly influenced cognitive psychology and our understanding of how we temporarily hold and manipulate information in our minds.
