What distinguishes Alan Baddeley's approach to working memory model from earlier approaches?
Introduction to Alan Baddeley's Approach
Alan Baddeley proposed his approach to the working memory model, which differed from earlier approaches due to its emphasis on active processing and manipulation of information. Unlike previous models that focused primarily on passive storage, Baddeley's model highlighted the dynamic nature of working memory.
Components of Working Memory
One key distinction of Baddeley's approach was the introduction of multiple components within working memory. He proposed three main components: the phonological loop, the visuospatial sketchpad, and the central executive. This tripartite structure provided a more detailed understanding of the different types of information processing and storage involved in working memory tasks.
The Role of Central Executive
Baddeley's model also included the concept of the central executive, which serves as a supervisory system responsible for managing attention, coordinating information between components, and integrating information from long-term memory. The central executive plays a crucial role in managing cognitive resources within working memory.
Emphasis on Active Processing
Overall, Alan Baddeley's approach to working memory model differed from earlier approaches by highlighting the importance of active processing, incorporating multiple components, and emphasizing the central executive's role in managing cognitive resources.
