Happy to see the hard work of our students getting recognition! 🎉 Kudos to Akvile Sinkeviciute for her MSc thesis (!) ending up in the top10% articles in Language Learning, showing that bilinguals perceive colours differently depending on the language they engage in! doi.org/10.1111/lang... 1/2

Three ManyBabies projects - big collaborative replications of infancy phenomena - wrapped up this year. The first paper came out this fall. I thought I'd take this chance to comment on what I make of the non-replication result. 🧵 bsky.app/profile/laur...
