Awareness as the heart of working memory

Area of Science:

• Cognitive Psychology
• Neuroscience
• Computational Modeling

Background:

• The multicomponent model of working memory is foundational in cognitive science.
• It initially comprised a central executive, phonological loop, and visuospatial sketchpad.
• The episodic buffer was later added to explain information integration.

Purpose of the Study:

• To trace the developmental trajectory of the multicomponent working memory model.
• To highlight the evolving role of the episodic buffer.
• To present a reformulated model with the awareness buffer at its core.

Main Methods:

• Historical analysis of working memory model development.
• Conceptual review of key theoretical shifts.
• Examination of the functional evolution of model components.

Main Results:

• The model evolved from a simple executive-control structure to a more integrated system.
• The episodic buffer's role expanded to include conscious accessibility and multidimensional integration.
• A reformulated model places the 'awareness buffer' as the central element.

Conclusions:

• Working memory models have progressively integrated more complex functions.
• The awareness buffer represents a significant conceptual advancement, unifying storage and executive control.
• This revised model offers a more comprehensive framework for understanding cognition.
