Biggest experimental study of Africa infant cognition! I’m very proud that we were able to get this project finished, despite COVID restrictions starting a month after our kickoff.

Exploring Variation in Infants' Preference for Infant‐directed Speech: Evidence From a Multi‐Site Study in Africa

Infants show a preference for infant-directed speech (IDS) over adult-directed speech (ADS). This preference has been linked to infants' language processing and word learning in experimental setting...

New ManyBabies publication! Over 10+ years and 5,000+ babies tested, we've learned a ton about how to study the developing mind. In this comment, we discuss three such lessons that are shaping the future of ManyBabies. We'd love to hear your thoughts!

Collective action is the most gratifying part of the reform movement. Grassroots groups like the many Many Manys are the most wonderful manifestation of it. Driven by curiosity and purpose, researchers come together to solve big problems with creative collaborations. That's why I science.

Evidence for Infant-directed Speech Preference Is Consistent Across Large-scale, Multi-site Replication and Meta-analysis

Abstract. There is substantial evidence that infants prefer infant-directed speech (IDS) to adult-directed speech (ADS). The strongest evidence for this claim has come from two large-scale investigati...

Then they compared their results to a traditional meta-analysis and MetaLab's community-augmented meta-analysis (langcog.github.io/metalab/), finding that the replications had much more homogeneous effect sizes and different moderators. (sorry, all of these slides are really exciting)

For example, for ManyBabies 1 ("Do babies prefer infant-directed speech vs. adult-directed speech?"), they tested >2K babies with 149 authors from 16 countries. The hypothesis could be confirmed - but there was also a methods effect and lots of variability through age and language.

@chbergma.bsky.social is now discussing replications versus meta-analyses in the context of infant studies. For example, at @manybabies.org, researchers are teaming up to promote open science and replications.
