q2 i? Mixed regression revealed a significant session × baseline age interaction in the left STG cluster, with opposite session 2 vs 3 patterns for younger vs older children. → Romanovska 2022 (2)

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 · r2

Post-hoc mixed regression on individual beta values from the longitudinal sample, with session, baseline age, reading fluency, recalibration effect and pre-test slope as within-subject covariates. The session × baseline age interaction was significant (F(2,13) = 8.702, p < 0.005).

"younger children showed higher left STG activation during session 2 compared to session 3 (mean difference = 0.596, t(11) = 2.950, p < 0.05), whereas older children showed more STG activation in session 3 compared to session 2 (mean difference = 0.502, t(10) = 2.918, p < 0.05)."

Romanovska 2022 (2)¶

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

Same mixed regression models: both the session × baseline age and session × recalibration effect interactions were significant in the left STG cluster only, with no significant interactions in the lateral inferior pre-CG.

"The analyses showed signi ficant interactions between session and children ’s baseline age [ F(2,13) = 8.702, p < 0.005] and between session and the recalibration effect [ F(2,17) = 5.808, p < 0.05] in the left STG cluster."

Discussion¶

Learner Variables¶

• Age and Developmental Stage — moderator: an instructional effect differs with it

• No significant behavioural text-based recalibration effect was observed in the MRI scanner environment across the three sessions — related
• Children showing stronger behavioural recalibration effects show more left STG activation in session 2 than session 3, regardless of age — related
• Phoneme-category response curves along the /aba/–/ada/ continuum remained stable across sessions, with a younger-child response bias toward /aba/ — related
• Lateral inferior pre-CG activation differed significantly between sessions 1 and 2, with other pairwise differences only at uncorrected levels — related
