Subclaims¶

q2 i? WM and STM are generally acknowledged as distinct constructs: WM differs from STM in the number of subsystems involved and in its emphasis on functional roles in learning, reasoning, and comprehension. → Demir 2021

Narrative review statement attributed to Baddeley (1996). The article notes some researchers use the terms interchangeably while others (Gathercole, 1998; Unsworth & Engle, 2007; Dehn, 2008) argue they are distinguishable; no effect size is printed.

"Baddeley differentiates the concept of WM from STM in two respects: the number of subsystems involved during the process and the considerable emphasis on its functional role in other cognitive tasks such as learning, reasoning, and comprehension."

Discussion¶

Related Claims¶

• The episodic buffer integrates multimodal representations from WM components and long-term memory, which is important for learning — related
• Same-construct memory task correlations exceed different-construct correlations — a narrower finding that bears on this claim
• The two-factor STM/WM structure holds for both younger (8-10) and older (11-13) children — a narrower finding that bears on this claim
• Working memory, but not short-term memory, predicts word decoding skill in children — a narrower finding that bears on this claim
• The central executive coordinates WM subsystems and supports higher-level language-learning functions such as attention switching and strategy switching — related
• Cowan's three-factor embedded processes model fit young children's working memory data slightly better than Baddeley and Hitch's three-factor model and decisively better than Baddeley's four-factor episodic buffer model — a narrower finding that bears on this claim
• Lesion evidence links written-language processes to language, working memory, and other cognitive skills
• Distinct neural substrates selectively support orthographic long-term memory and orthographic working memory in spelling — related
• Processing speed is linked to working memory in both studies, but its link to short-term memory is inconsistent across studies — a narrower finding that bears on this claim
