Asking or Telling--Real-time Processing of Prosodically Distinguished Questions and Statements

Area of Science:

• Psycholinguistics
• Speech Perception
• Cognitive Science

Background:

• Understanding how intonation affects language interpretation is crucial for psycholinguistics.
• Previous research has explored prosody's role, but online processing remains an area of active investigation.

Purpose of the Study:

• To investigate the online processing of intonational contours in sentence interpretation.
• To determine if intonation signals linguistic categories or adapts rapidly to experimental paradigms.
• To assess the interaction of prosody with other cues in determining sentence type.

Main Methods:

• Utilized a targeted language game approach with a visual world, eye-movement paradigm.
• Created a computer-based card game presenting elliptical utterances with distinct intonational contours (question vs. statement).
• Analyzed eye-movement patterns and timing to index online interpretation.

Main Results:

• Intonational contours had an immediate effect on utterance interpretation, evidenced by fixation patterns and timing.
• The association between specific contours and listener intentions was robust, even without clear syntactic cues.
• Prosody's influence persisted despite a grammatical bias towards interpreting certain constructions as questions.

Conclusions:

• The developed paradigm offers new insights into the online comprehension of intonation.
• Prosody plays a significant and immediate role in shaping sentence interpretation.
• Intonational contours robustly signal communicative intentions, independent of rapid adaptation.
