Subclaims¶

q2 i? Greater pre-intervention reliance on imageability was significantly associated with less residualized gain in Sight Word Efficiency, in line with the untimed Letter-Word Identification result. → Siegelman 2022

q2 · i? · associational · r2

Stepwise regression predicting Sight Word Efficiency gains in the 118-child RD intervention sample; the second-step model improved fit, F(4, 116) = 2.77, p = .031, showing "greater pre-intervention reliance on imageability significantly associated with less residualized gains".

"The second step model again showed improved model fit compared to the intercept-only model (F(4, 116) = 2.77, p = .031), with greater pre-intervention reliance on imageability significantly associated with less residualized gains"

Discussion¶

Learner Variables¶

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

Related Claims¶

• Greater reduction in reliance on imageability over the intervention is associated with greater residualized gains in Passage Comprehension — related
• Word reading task measures of O-P and imageability reliance predict intervention gains beyond vocabulary, phonological awareness, rapid naming, and auditory attention — a broader claim this one bears on
• The phonologically-weighted intervention increased children's mean reliance on O-P regularities from pre- to post-intervention, with no significant mean change in imageability reliance — related
