a statistical trendp = .085
All age effects remained significant with large effect sizes (η 2 p ≥.14), except for the modality-by-age interaction across the whole RPE network, which showed a statistical trend ( p = .085; see Supplementary Material B.7 for more details). 4 Discussion This study provides insights into the behavioural and neural processing underlying multisensory learning in children, focusing on audio-visual and tactile-visual associations.
