Abstract:
During natural communication, caregivers pitch statistics at infants, and infants figure out what to pay attention to across milliseconds and months. In doing so, they make progress in detecting and then running with meaningful, naturally variable structure in their environments. I will present recent studies examining how caregivers package language to infants, how infants process patterns in the complexities of their input, and how infant-adult dyads align their brains and behaviors during natural play. I will also present preliminary analyses suggesting that such alignment is relevant to children's learning of new information. The data collectively suggest that fine-grained, predictable statistics embedded in everyday communication are key to understanding the dynamic and consequential nature of early learning.
