Subclaims¶

q3 i? By age 10, attention robustly increased late-N1 amplitude for linguistic probes, and the modulation persisted at 13, 16, and adulthood. → Karns Christina M. 2015

q3 · i? · causal · r2

In the dichotic story ERP study, linguistic-probe late-N1 amplitude showed significant attention modulation at every age from 10 years onward: "p < .001" at 10 years, an Attention x Hemisphere interaction at 13 (F(1,17) = 14.8, p = .001), and p < .05 at 16 and in adults. No late-N1 was present in 3–5-year-olds.

"By age 10 years, attention robustly increased the late-N1 amplitude (p < .001). At age 13 years, attention interacted with hemisphere (Attention x Hemisphere: F(1,17) = 14.8, p = .001). By age 16 years, attention increased the late-N1 amplitude (p < .05), as it did with adults (p < 0.05)."

Discussion¶

Learner Variables¶

• Attention — predictor: learners who differ on it differ in outcomes
