Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Factor analyses of training and transfer data suggested two separate processes: an early task-specific improvement accounting for 44% of the total increase, and a slower capacity improvement. → Julia Ericson and Torkel Klingberg 2023

Confirmatory factor analysis of performance data from 1300 children on the trained Grid task and 3 transfer tasks (OOO, FI, Math), tested for strict longitudinal measurement invariance. The article reports "an early task-speci fic improvement, accounting for 44% of the total increase, and a slower capacity improvement."
"Factor analyses suggested two separate processes: an early task-speci fic improvement, accounting for 44% of the total increase, and a slower capacity improvement."
Discussion¶
Learner Variables¶
- Working Memory — outcome: instruction changes it
Related Claims¶
- Capacity improvement increased continuously throughout training while task-specific improvement occurred only between the first two test sessions — related
- Individual slopes of the trained task correlated significantly with slopes of the odd-one-out and following-instructions transfer tasks but not with the math task — 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 — related
- Working memory capacity increases with age independently of knowledge, encoding speed, and articulation — related
- Brain games produce statistically significant cognitive performance gains in older adults, but gains are modest and do not detect improvements over control tasks or produce far transfer — related
