q2 i3 Toddlers whose sleep varied night to night in timing and duration had longer target P3 latencies (r[18]=.61). → Hoyniak 2015

Correlational analysis in the same toddler sample; irregular sleep was an actigraph-derived factor of night-to-night standard deviations of sleep timing and duration variables. The study reports "a significant positive association between target P3 latencies and irregular sleep" with a printed effect size of r[18]=.61 (p=.004).

"Additionally, results demonstrated a significant positive association between target P3 latencies and irregular sleep (r[18]=.61, p=.004), such that children with sleep that varied from night to night in timing and duration had longer target P3 latencies."

Discussion¶

Learner Variables¶

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