Subclaims¶

q2 i1 Reliance on O-P was significantly stronger post-intervention (M = 0.39) than pre-intervention (M = 0.31), d = 0.39. → Siegelman 2022

Siegelman 2022¶

Siegelman, N., Rueckl, J. G., van den Bunt, M., Frijters, J. C., Zevin, J. D., Lovett, M. W., Seidenberg, M. S., Pugh, K. R., & Morris, R. D. (2022).

q2 · i1 · causal · r1

Paired comparison of O-P slope scores pre- vs post-intervention in 118 children with RD; the intervention "resulted in an increased sensitivity to sub-lexical O-P regularities at the group-level", d = 0.39, t(117) = 4.39, p < 0.001.

"reliance on O-P was significantly stronger post-intervention compared to pre-intervention: Mpre = 0.31, SDpre = 0.21; Mpost = 0.39, SDpost = 0.20; t(117) = 4.39, p < 0.001, d = 0.39."

Discussion¶

Learner Variables¶

• Decoding — outcome: instruction changes it
