Eye-tracking studies tested the understanding of two types of speech acts (questions and assertions) in 14-, 18-, and 30-month-olds (N = 280; 149 females; ethnicity data collection forbidden, testing in 2021-2024). Experiments involved objects either hidden or visible for a speaker. By 14 months, when the speaker asked questions, infants focused…
