Subclaims¶

q3 i? In the final CFA model, transfer improvements were driven by the capacity factor alone, capacity increased continuously throughout training, and task-specific improvement increased only between T1 and T2. → Julia Ericson and Torkel Klingberg 2023

q3 · i? · associational · r2

CFA results from the final model (RMSEA = 0.036, CFI = 0.984) fitted to data from 1300 children across 5 test sessions. The article reports "Cap increased continuously throughout the training period while TS increased only between T1 and T2."

"First, the transfer improvements were driven by Cap alone while the improvement on Grid was a combination of both Cap and TS. Second, Cap increased continuously throughout the training period while TS increased only between T1 and T2"

Related Claims¶

• Working memory training improvement decomposes into an early task-specific process accounting for 44% of the total increase and a slower capacity improvement — related
• HMM-derived task-specific and capacity parameters correlate with the corresponding CFA estimates, validating the daily-data model — related
