Working memory training

Overview

  • Influence: Working memory training
  • Domain: Student Learning Strategies
  • Sub-Domain: Learning strategies
  • Potential to Accelerate Student Achievement: Likely to have positive impact
  • Influence Definition: The capacity to temporarily retain and manipulate information. It is often claimed to consist of four components: the phonological loop; the visuospatial sketchpad; the episodic buffer integrates or ‘binds' and consequently stores information from the phonological loop and visuospatial sketchpad with long-term memory; and then these three storage systems work under the influence of the central executive, which is responsible for retrieving and manipulating information, and directing resources to the storage components.
