Subclaims¶

q2 i? A session × exposure-block × post-test-sound RM ANCOVA on /aba/ response proportions showed no significant main or interaction effects. → 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? · causal · r1

Behavioural analysis of auditory-only post-test responses in the same 18-child longitudinal fMRI sample. All children responded differently to post-test sounds after "aba" vs "ada" exposure, but the omnibus RM ANCOVA found no significant recalibration effect; equivalence was not tested.

"a 3 (session) × 2 (“aba” / “ada” exposure block) × 3 (post-test sounds) RM ANCOVA did not show signi ficant main- or interaction effects (all F ≤ 2.19), indicating a lack of a signi ficant behavioural recalibration effect across participants."

Discussion¶

Related Claims¶

• Phoneme-category response curves along the /aba/–/ada/ continuum remained stable across sessions, with a younger-child response bias toward /aba/ — possibly the same claim (merge candidate)
• Children showing stronger behavioural recalibration effects show more left STG activation in session 2 than session 3, regardless of age — related
• Left STG developmental activation change interacts with baseline age: younger children peak at session 2, older children show more activation at session 3 — related
• Cortical activation changes were not linked to reading fluency or phoneme perception, and pre-CG showed no significant covariate interactions — related
