q3 i? Toddlers performed significantly above chance on delayed memory tests for word-object (65.14% Control, 62.38% Study) and letter-sound (69.19% Control, 70.54% Study) associations, with no group differences. → Peña 2024 q3 i? Preschoolers performed significantly above chance on delayed memory tests for word-object (78% Control, 77% Study) and letter-sound (63.97% Control, 64.14% Study) associations, with no group differences. → Peña 2024 (2)

q3 · i? · causal · r2

Long-term memory test 4-6 months post-intervention in 11 Control and 16 Study toddlers; both groups above chance with no significant differences (word-object P > 0.570; letter-sound P > 0.77). "Both groups performed signi ficantly above chance in the word-object task"

"Both groups performed signi ficantly above chance in the word-object task (65.14% for the Control group and 62.38% for the Study group) and in the letter-sound task (69.19% for the Control group and 70.54% for the Study group)."

q3 · i? · causal · r2

Long-term memory test in 31 Control and 27 Study preschoolers 4-6 months post-intervention; "All preschoolers performed with an accuracy significantly above the chance level (50%)" in both tasks, with no significant group differences (P > 0.070).

"All preschoolers performed with an accuracy significantly above the chance level (50%) in both the word-object task (78% and 77% for Control and Study group, respectively) and the letter- sound task (63.97% and 64.14% for Control and Study group, respectively)."
