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 i3 WM capacity correlates positively with all four conditions, with coefficients from .398 to .586. → Sung JE 2015

Pearson correlations between a composite WM-capacity index (average of digits-forward, digits-backward, words-forward, words-backward tasks) and accuracy on the four production conditions in the same 60-participant study. The article prints coefficients ". 503,. 586,. 474, and. 398", including r = .586 for the priming-noncanonical condition.
"WM was significantly and positively correlated with all conditions of the sentence-production tasks with the correlation coefficients of. 503,. 586,. 474, and. 398, (all ps < .01)"
Discussion¶
Learner Variables¶
- Working Memory — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Age is significantly and negatively correlated with passive-sentence production accuracy across all four task conditions in Korean adults — related
- The syntactic-priming task with noncanonical word order is the best single predictor of age among the four sentence-production conditions — related
- Working memory capacity is a robust indicator of success or failure in language learning — related
- WM capacity is significantly and negatively correlated with age in Korean adults — related
- After controlling for age, WM correlates significantly only with the most demanding condition (priming task, noncanonical word order) — reports the opposite
- Adults with greater memory capacity, measured by WAIS Digits Backward, produced more complex utterances and used more right- and left-branching clauses — related
- Two distinct implicit cognitive processes show different predictive links: implicit learning predicts skill learning, associative memory activation predicts language task success — related
