Subclaims¶

q2 i? In toddlers, no significant correlations were observed between game accuracy and standardized gains in ASQ-3 Communication or CDI Adverbs and Verbs scores. → Peña 2024 q2 i2 In preschoolers, higher TECAL total gain correlated with higher encoding-phase accuracy in the letter-sound task (r = 0.34, P = 0.005) in the Study group. → Peña 2024 (2)

Evidence¶

Peña 2024¶

Peña, M., Vásquez-Venegas, C., Cortés, P., Pittaluga, E., Herrera, M., Pino, E. J., Escobar, R. G., Dehaene-Lambertz, G., & Guevara, P. (2024). A brief tablet-based intervention benefits linguistic and communicative abilities in toddlers and preschoolers. npj Science of Learning. https://doi.org/10.1038/s41539-024-00249-3

q2 · i? · causal · r2

Bivariate correlation analysis of toddler game performance against linguistic gains; "No significant correlations were observed b etween game accuracy and standardized gain" in any comparison. The authors suggest the intervention may have trained mainly domain-general abilities.

"No significant correlations were observed b etween game accuracy and standardized gain in the ASQ-3's Communication Domain scores or the CDI's Adverbs and Verbs scores in any comparison ( P > 0.21 for the Control group andP > 0.12 for the Study group)."

Peña 2024 (2)¶

q2 · i2 · causal · r2

Bivariate correlation in the preschooler experiment: "higher standardized gain in TECAL total score correlated with higher mean accuracy in the encoding phase of the letter-sound task" (r = 0.34, P = 0.005), which the authors read as support for general-domain mechanisms.

"The bivariate correlation analysis revealed a significant correlation in the Study group showing that higher standardized gain in TECAL total score correlated with higher mean accuracy in the encoding phase of the letter-sound task (Pearson correlation coef ficient = 0.34, P = 0.005)"
