Subclaims¶

q3 i1 The continuously cumulating meta-analysis pooled effect size was negative and significantly different from zero (r = -0.115, p = 0.035), with near-zero heterogeneity. → Pedraza 2024

Fixed-effect meta-analytic model pooling the two studies' correlations between EF factor scores and implicit SL. The quote reports "r = −0.115, 95% CI = [-0.218, -0.008], p = 0.035"; heterogeneity variance was τ2 = 0 with I2 of 0% and non-significant Cochran's Q.

"The pooled effect size was negative and significantly different from zero, r = −0.115, 95% CI = [-0.218, -0.008], p = 0.035 (Fig. 6). The weights of Study 1 and Study 2 in the pooled effect were 54.3% and 45.7%, respectively."

Discussion¶

Related Claims¶

• Executive ability affected general skill learning in Study 2 but not Study 1, and affected overall implicit SL rather than the learning trajectory — related
• Implicit statistical learning is negatively correlated with a latent executive-function factor comprising verbal fluency and complex working memory in Study 1 — possibly the same claim (merge candidate)
• Study 2 replicates the negative SL–EF factor 1 correlation while EF factor 2 (short-term memory) shows no association with implicit SL — a narrower finding that bears on this claim
• At the task level, implicit SL correlates negatively with most individual executive-function measures, strongest with verbal fluency tasks — related
• Participants showed robust implicit statistical learning and general skill learning on the ASRT task in both studies — related
