Anjie chats with Dr.Casey Lew-Williams.  Casey is a Professor at Princeton University, where he also directs the Princeton Baby Lab. He studies how babies learn, with a particular focus on language and communication. In this episode, we chat about a recent preprint he co-authored with Dr. Jessica Kosie titled "Infant-Directed Communication: Examining the multimodal dynamics of infants’ everyday interactions with caregivers". Casey shares his thoughts on why it is important to study and how to study infant-directed communication.  If you found this episode interesting at all, subscribe on our Substack and consider leaving us a good rating!
