Nota Bene:

This has been another fun project – with the inevitable @audunrosslund.bsky.social and @nataliakartushina.bsky.social!

As usual – the data is openly available (+ pre-registration + author version): osf.io/s8zrm/.

Final Takeaway 🎯

Our findings challenge the idea that acoustic modulation in IDS is a direct lexical teaching strategy.

IDS likely serves broader goals: sustaining attention, conveying affect, and social bonding.

Our Bayesian analyses provided decisive evidence against the didactic effect, suggesting that parents do not adapt their speech based on their child individual word’s attributed knowledge. Twist: vowel dispersion increased for known words with age!

This may suggest reinforcement, not instruction 🤔

Oh boy! Second language learning is not my field, but establishing a time to learn will depend on (among many others), (a) your age, (b) proximity to your first language, (c) what you mean by "learn" or "know" a language, (d) intrinsic motivation to learn, (e) cognitive ability, (f), (g), etc, etc!

It looks like there are lines with twice the slope - two-tailed versus one-tailed? I wonder if this constrains your regression line in a weird way...

From this view, data-driven age thresholds suggest older girls adopt a caregiving role a couple of years earlier than boys!

This suggests it's about household dynamics and potential resource balance, not just your spot in line!
