Audiovisual Correlates of Interrogativity: A Comparative Analysis of Catalan and Dutch

Languages employ different strategies to mark an utterance as a polar (yes–no) question, including syntax, intonation and gestures. This study analyzes the production and perception of information-seeking questions and broad focus statements in Dutch and Catalan. These languages use intonation for marking questionhood, but Dutch also exploits syntactic variation for this purpose. A production task revealed the expected language-specific auditory differences, but also showed that gaze and eyebrow-raising are used in this distinction. A follow-up perception experiment revealed that perceivers relied greatly on auditory information in determining whether an utterance is a question or a statement, but accuracy was further enhanced when visual information was added. Finally, the study demonstrates that the concentration of several response-mobilizing cues in a sentence is positively correlated with the perceivers’ ratings of these utterances as interrogatives.
