Question

What are the changes from the Baddeley 2000 model to the new Baddeley 2012 model?

Answer 1

In 2000, Baddeley proposed a model of memory that included three components: the phonological loop, visuospatial sketchpad, and central executive. However, in 2012, Baddeley updated his model to include two additional components: the episodic buffer and the fourth component was added to explain interactions between the other components.

This new model improves our understanding of how we store and retrieve memories. The episodic buffer acts as a temporary storage unit for information from all the other components before it is transferred to long-term memory. This addition helps us understand how we can remember complex events with multiple sensory inputs.

Additionally, the fourth component serves as a way to integrate information from the other components to help guide decision-making and problem-solving. By updating this model, Baddeley has provided a more comprehensive framework for studying human memory that allows researchers to better investigate how different cognitive processes interact.

Answer 2

The Baddeley 2000 model proposed that working memory consisted of three components: the phonological loop, the visuospatial sketchpad, and the central executive. In this model, the central executive was considered a general-purpose attentional control system that could direct attention to different tasks and coordinate the other two components.

The Baddeley 2012 model built upon the previous model and included a fourth component, the episodic buffer. The episodic buffer is responsible for integrating information from the phonological loop, the visuospatial sketchpad, and long-term memory into a single, coherent representation that can be used for higher-level cognitive processes such as reasoning and problem-solving.

Additionally, the central executive was further elaborated in the Baddeley 2012 model to include two distinct attentional control systems: the supervisory attentional system and the attentional control network. The supervisory attentional system is responsible for controlling and coordinating the other three components of working memory, while the attentional control network is involved in goal-directed attentional control and conflict resolution.

Overall, the Baddeley 2012 model expands upon the Baddeley 2000 model by including a new component (the episodic buffer) and elaborating on the functions of the central executive.
