Accessibility of Referent Information Influences Sentence Planning: An Eye-Tracking Study

Area of Science:

• Psycholinguistics
• Cognitive Science
• Computational Linguistics

Background:

• Sentence formulation involves complex cognitive processes.
• Understanding the time-course of sentence planning is crucial for psycholinguistic models.
• Discourse context significantly influences language production.

Purpose of the Study:

• To investigate the time-course of online sentence formulation.
• To examine how discourse context affects sentence planning incrementality.
• To determine the role of agent and patient accessibility in sentence production.

Main Methods:

• Two eye-tracking experiments were conducted.
• Participants described transitive events (e.g., a frog catching a fly).
• Agent and patient accessibility were manipulated in preceding discourse (Literal, Associative, No Mention conditions).

Main Results:

• Eye movements indicated participants looked at the agent before speech onset and the patient around/after speech onset.
• Sentence formulation was sensitive to literal mention of the agent, and to a lesser extent, conceptual accessibility.
• Patient accessibility, whether literal or conceptual, did not affect the time-course of utterance planning.

Conclusions:

• Linguistic planning before speech onset is primarily influenced by the accessibility of the agent's name.
• Findings support the theory of highly incremental planning in sentence production.
• Discourse context plays a critical role, particularly in the initial stages of sentence formulation.
