Please add us!

These findings link fluctuations in autonomic nervous system activity with language production. We hope they provide new avenues for understanding the extended systems supporting language development and help us to find possible markers for early intervention in at-risk infants.

Amazingly, vocalizations produced just before the trough, while heart rate is decelerating, were more likely to be recognized as a word by naive listeners!

Infants were most likely to produce a vocalization when their heart rate fluctuations reached a peak (local maximum) or trough (local minimum). Vocalizations produced at the peak were longer than expected by chance.

This is awesome, thank you! Would you mind adding us?
