Draw a Star and Make it Perfect: Incremental Processing of Telicity.

Area of Science:

• Psycholinguistics
• Cognitive Science
• Linguistics

Background:

• Predicates describe events with duration and endpoints (telos).
• Perfective aspect implies event completion, but early reader commitment to event boundedness varies.
• Previous studies show early integration of aspectual and temporal cues in sentence processing.

Purpose of the Study:

• To investigate the incremental processing of the perfective aspect in Italian.
• To compare the processing of telic durative predicates with punctual predicates.
• To examine how linguistic and visual cues interact to derive culmination inferences.

Main Methods:

• Utilized the visual-world paradigm with eye-tracking in two experiments.
• Presented listeners with durative predicates in perfective form in scenarios depicting completed and non-completed events.
• Compared telic durative predicates (e.g., 'coloring-the-star') with punctual predicates (e.g., 'lighting-the-candle').

Main Results:

• Perfective aspect incrementally triggers culmination inferences during sentence processing.
• For durative predicates, culmination inference requires integrating visual event completion with linguistic perfective aspect.
• Punctual predicates have lexically encoded telicity and culmination inferences in the perfective verb.

Conclusions:

• Novel evidence supports continuous integration of linguistic processing with real-world visual information.
• The perfective aspect plays a crucial role in incrementally deriving culmination inferences.
• Visual context is essential for interpreting the completion of durative events expressed in the perfective aspect.
