q3 i? A grade × time point interaction driven by eighth graders' significant reduction in performance at 2 months versus 3 days (d = 1.23), not seen in sixth graders. → Brian Mathias 2022

Twelve- and Fourteen-Year-Old School Children Differentially Benefit from Sensorimotor- and Multisensory-Enriched Vocabulary Training.

q3 · i? · causal · r2

Mixed effects modeling of composite scores across time points in the 75-child intervention; the time point main effect was χ2 (2, N = 75) = 25.57, p < 0.001, v = 0.41, attributed to reports of memory decay over time.

"The grade level × time point interaction was driven by a significant reduction in performance at 2 months post-learning compared to 3 days post-learning for the eighth graders (β = 1.38, t = 5.14, p < 0.001, d = 1.23), which did not occur for the sixth graders (β = 0.45, t = 1.74, p = 0.50, d = 0.40)"

• Concrete L2 words are learned better than abstract words overall, but this concreteness advantage appears only in 14-year-olds — related
• Gesture-enriched L2 vocabulary learning benefits 14-year-olds more than picture enrichment, while 12-year-olds benefit equivalently from both — related
