Subclaims¶

q2 i? The central executive controls the phonological loop and visuospatial sketchpad, relates them to long-term memory, and is responsible for language-learning functions including strategy switching, selective attention, retrieval from long-term memory, and dual-task coordination. → Demir 2021

q2 · i? · theoretical · r2

Narrative review statement attributed to Baddeley (1996) and Morris & Gruneberg (1994). The CE is described as the most complex and powerful WM component, a flexible but limited-capacity workspace; no effect size is printed.

"This system is responsible for the specific functions of learning a language such as a strategy switching, selective attention, retrieval from long-term memory and dual-task coordination, which represent higher-level cognition tasks."

Discussion¶

Learner Variables¶

• Executive Function — predictor: learners who differ on it differ in outcomes
• Working Memory — predictor: learners who differ on it differ in outcomes
