Subclaims¶

q3 i? The DD group scored significantly lower than the TR group on syllable, letter and word reading tasks, with no difference on visual symbol recognition. → Cao 2026

q3 · i? · causal · r1

Independent-samples t-tests on posttests in 62 adults: "the DD group scored significantly lower than the TR group on each of the Syllable, Letter, and Word reading tasks" (all ts > 2.10, all ps < .05); no group difference on visual symbol recognition. No effect sizes printed for these group contrasts.

"the DD group scored significantly lower than the TR group on each of the Syllable, Letter, and Word reading tasks (all ts > 2.10, all ps < .05). No significant differences were observed between the two groups on the more basic visual symbol recognition task (Posttest Visual)."

Discussion¶

Learner Variables¶

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