Subclaims¶

q3 i? Preschoolers who played the game showed greater standardized gain than Controls in the TECAL vocabulary subscale (r = -0.12) and total scores (r = -0.18). → Peña 2024 q3 i? No significant group differences were found for TECAL morphology, syntax, or TEPROSIF phonological production. → Peña 2024 (2)

q3 · i? · causal · r2

Pre-post equivalent-group experiment with 152 preschoolers (~42 months); Study group (n=68) showed greater TECAL vocabulary gain than Control (n=76), Wilcoxon-Mann-Whitney Z = -2.34, P = 0.019, r = -0.12; total score Z = -2.15, P = 0.031, r = -0.18. "the Study group had signi ficantly greater standardized gain than the Control group in the TECAL vocabulary subscale and total scores"

"When comparing the groups, the Study group had signi ficantly greater standardized gain than the Control group in the TECAL vocabulary subscale and total scores (Table 2 and Fig. 3a)."

q3 · i? · causal · r2

In the same preschooler experiment, no significant group differences emerged for TECAL morphology (P = 0.112), syntax (P = 0.884), or TEPROSIF total (P = 0.702); category differences "were not found in TECAL" or TEPROSIF. Equivalence was not tested.

"(at-risk, delay, normal) were not found in TECAL (Fisher 'se x a c t probability > 0.638) or TEPROSIF ( P = 0.702)."
