Subclaims¶

q2 i? Pre-test /aba/ response proportions to the nine continuum sounds did not change across sessions, but interacted with baseline age. → Romanovska 2022

Evidence¶

Romanovska 2022¶

Romanovska, L., Janssen, R. & Bonte, M. (2022). Longitudinal changes in cortical responses to letter-speech sound stimuli in 8–11 year-old children. npj Science of Learning 7:2. https://doi.org/10.1038/s41539-021-00118-3

q2 · i? · associational · r1

Pre-test in a mock scanner (98 presentations of each of 9 tokens) used to individually determine the most ambiguous sound. A session × sound RM ANCOVA showed a sound main effect and a sound × baseline age interaction; younger children's responses were "biased more towards /aba/".

"revealed a main effect of sound [F(2,24) = 4.087, p < 0.05, Greenhouse-Geisser corrected] and an interaction between sound and children ’s age in months during session 1 (baseline age) [F (2,24) = 5.629, p < 0.01, Greenhouse-Geisser corrected]."

Discussion¶

Learner Variables¶

• Age and Developmental Stage — predictor: learners who differ on it differ in outcomes

Related Claims¶

• Cortical activation changes were not linked to reading fluency or phoneme perception, and pre-CG showed no significant covariate interactions — related
• No significant behavioural text-based recalibration effect was observed in the MRI scanner environment across the three sessions — possibly the same claim (merge candidate)
• Left STG developmental activation change interacts with baseline age: younger children peak at session 2, older children show more activation at session 3 — related
