Like adults, children parse sentences incrementally. Consequently, they often have difficulty revising their initial parse of a sentence when it turns out to be incorrect. Unlike adults, children have more difficulty recovering from mis-analysis (this is often called the "Kindergarten path effect"). In this talk, I will explore whether differences in child-directed vs. adult-directed speech (as measured by surprisal values at each word in garden path sentences) could help explain the KPE.
