q3 i? The autistic control group showed no significant improvement in on-focus expansion across acoustic cues between the two production sessions. → Chen 2026

Evidence¶

Chen 2026¶

Chen, S., Wang, B.X., Cheung, J.C.-W. et al. (2026). Lab perceptual training and robot-assisted training in improving speech prosody of autistic children. npj Science of Learning. https://doi.org/10.1038/s41539-026-00425-7

q3 · i? · causal · r?

Untrained autistic control group tested in two speech production sessions separated by the training period; LMM post-hoc comparisons showed no significant on-focus improvement. No effect size printed; equivalence was not tested.

"Overall, these results suggest that there is no significant improvement in on-focus expansion for the control group in using acoustic cues such as f0, duration and intensity."
