q3 · i? · causal · r1

Follow-up analysis addressing the potential lexical overlap between training material and test sentences. The correlation between sentence-training time and audiovisual learning effects "showed no signi ficant effect ( r = 0.04, p = 0.837)", which the authors interpret as support that lexical overlap was not a relevant confound.

"We then correlated the amount of time that was spent during training in sessions where sentences were speci fically trained with the learning effects in the audiovisual condition which showed no signi ficant effect ( r = 0.04, p = 0.837)."

• Participants who improved on audiovisual speech-in-noise comprehension had significantly lower pre-training scores than non-learners, reflecting the inherent correlation between baseline and change scores — related
• Three weeks of computer-based speechreading training improves audiovisual speech-in-noise comprehension in middle-aged and older adults, with the effect limited to the audiovisual condition — a broader claim this one bears on
• Speechreading training does not significantly improve subjectively perceived everyday listening effort or hearing abilities — related
