"Who's my happy baby? Yes, you are!" The scoop on infant directed speech! (with Martin Zettersten)

In this episode, we chat with Dr. Martin Zettersten about a ManyBabies project that he was a part of, which assessed the reliability of infant directed speech as well as the conditions that affect whether infants show a preference for it over adult directed speech. We also talk about Martin's journey in cognitive science, life as a new assistant professor, and how he met Deon loooong ago! We hope you enjoy this episode.
