Had fun writing this homage to Roy et al., 2015, who demonstrated that language learning is tied to spatial+temporal context. I touch on ecological validity, power, and boldness in study design in dev.psych. A slightly mad study showing just how cool science can be! #DevSci #devpsy #langsky

Do parents exaggerate the pronunciation of words they believe their infants don’t know yet? Our new paper suggests no. ❌ w/ @julienmayor.bsky.social & @nataliakartushina.bsky.social 🧵 1/ #DevSci #langsky #devpsy

Do older siblings help or hinder language development? And does it matter if they’re sisters or brothers? In our new paper we revisit the "birth order effect"... and took it a step further! w/ @julienmayor.bsky.social, Nora Serres and Natalia Kartushina 🙌 🧵 1/ #DevSci #langsky #devpsy
