Talk Title: How to Grow a Lexicon: Evidence from Babies & their WorldsAbstract: While a longstanding view in language development holds that infants don't understand words until they begin talking (around age 1), recent research in our lab and others has revealed that infants begin understanding words months earlier. In this talk I will explore two branches of my lab’s work that tackle the mechanisms of early language development, largely focused on building the early lexicon. First, I will discuss eyetracking data revealing infants’ initially imature expectations about how words sound and what they mean, and how their representations eventually become more adult-like over infancy and toddlerhood. Synthesizing across studies, I will discuss recent results showing a robust, non-linear, and arguably qualitative improvements in infants’ real-time word comprehension just after the first birthday. Second, drawing from SEEDLingS, my lab’s audio and video corpus of home recordings, I will argue that this “comprehension boost” is not well-explained by changes in language input for common words, but rather, by postulating that infants learn to take better advantage of relatively stable input data. I will propose complementary theoretical accounts of what makes older infants “better learners.” Finally, I will also discuss the dynamics of language learning in infants who are blind and infants who are Deaf/Hard of Hearing, considering how their unique perceptual experiences dovetail with their accruing linguistic knowledge.Bio: Dr. Bergelson is the John L.

Speaker: George Barbastathis (MIT)

Have you ever wondered what truly shapes the future you’re working toward—whether in a project, passion, or everyday decision?In this interactive workshop, hosted by the Global Health Alliance in collaboration with MIT Radius, you’ll explore what drives your work and where your decisions take you. Using a simple yet powerful framework, we’ll reflect on:The futures you’re envisioning (big or small)The people your actions touchThe values behind your choicesThe moments when small decisions really matterBring a passion, project, or activity you care about, and we’ll guide you through thought-provoking questions designed to open up new perspectives and possibilities. You’ll leave with sharper insight into how your actions fit into the bigger picture and a clearer understanding of what truly matters to you.
