I am interested in the interaction between sounds and meaning, and the linguistic mechanism behind the effect. Specifically, a sentence “All of the apples didn’t fall (from a tree)” with falling intonation at the end is ambiguous between the “none fell”-reading and the “not all fell”-reading – on the other hand, the same sentence with a stress on “All” and rising intonation at the end will unambiguously yield the “not all fell”-reading. My research investigates theoretical background of such phenomena (similar examples can be found in different types of sentences in different languages) and whether children and foreign language learners are sensitive to the effect.
