Subclaims¶

q3 i? PES in either the incongruent or mixed block of the HF task was not associated with intelligence or WM (all ps > .056), even after controlling for age, and hierarchical regressions confirmed null predictions. → Ger Ebru 2023 q3 i? The trajectory of PES across a block did not vary as a function of intelligence: neither the three-way interaction nor the block × index interaction was significant. → Ger Ebru 2023 (2)

q3 · i? · associational · r2

Pre-registered correlational analyses in the N = 147 sample found no PES–intelligence or PES–WM associations. Pre-registered hierarchical regressions predicting PES (Table 3) added no variance: intelligence step ΔR2 = −0.006 in the mixed-block model.

"Regarding cognitive control, PES in either block of EF was not associated with intelligence or WM (all ps > .056), even after controlling for age"

q3 · i? · associational · r3

Exploratory mixed linear regression on trial-level RTs tested whether PES magnitude across errors varied with intelligence. Neither the three-way interaction nor the two-way interaction was significant, so the PES trajectory was independent of intelligence.

"Model comparisons revealed neither a significant three-way interaction (Χ2(3) = 0.46, p = .927) nor a two-way interaction between the block and index (Χ2(3) = 0.48, p = .487)"

Discussion¶

Related Claims¶

• Accuracy in the mixed block decreases across trials while PES also decreases, independent of intelligence — related
• Exploratory WM-task measures correlate with EF indices: inhibition accuracy with correct colors, PES mixed with verbal span, congruency effect with correct locations — reports the opposite
• Post-error behavioural adjustments can occur automatically, dissociated from explicit error detection — related
• Inhibition accuracy is marginally correlated with verbal WM but not visuospatial WM in kindergarten children — related
• Shifting accuracy and shift cost show no association with intelligence or WM in kindergarten children — related
• PES is robustly present in kindergarten children and decreases over the course of a task block — related
• Mean RT in HF blocks is negatively correlated with visuospatial WM and mixed-block RT positively with intelligence — related
• Inhibition accuracy in the Hearts and Flowers incongruent block is positively correlated with fluid intelligence in kindergarten children — related
• Mean RT in the shifting block is positively correlated with intelligence, counterintuitively, in kindergarten children — related
