Looking at a contrast object before speaking boosts referential informativeness, but is not essential.

Area of Science:

• Psycholinguistics
• Cognitive Science
• Linguistics

Background:

• Traditional theories of referential form focus on linguistic and discourse factors.
• Eye tracking in psycholinguistics is increasing, but its role in informative reference production is understudied.

Purpose of the Study:

• To investigate the relationship between visual scanning behavior and the production of informative referring expressions.
• To determine if visual attention to referents influences how speakers describe objects.

Main Methods:

• Participants produced referring expressions for target objects in visual scenes.
• Eye movements (fixations) were tracked during speech planning and production.
• The informativeness of referring expressions was analyzed in relation to visual fixations.

Main Results:

• Speakers generally produced informative descriptions, especially in simpler displays.
• Fixations on contrast objects boosted informativeness but were not essential.
• Fixations during speech planning facilitated but did not fully predict informative reference; pragmatic expectations may be more critical.

Conclusions:

• Direct visual scanning is not a prerequisite for informative reference production.
• Pragmatic factors and goal-based processing likely play a significant role in linking eye movements and language production.
• This study offers a novel application of eye-tracking to language production processes.
