CASE STUDY: Eye Tracking to Understand Conflict During a Conversation in Real Time
Effective communication relies heavily on our ability to understand not just the words being spoken, but also the speaker’s underlying intent and perspective. In real-time language comprehension, listeners constantly integrate linguistic input with contextual information to interpret meaning. A crucial aspect of this process is “common ground” – the shared knowledge, beliefs, and assumptions between conversational partners. However, what happens when this common ground is challenged, or when perspectives conflict? This is the core research issue explored by Barr et al. (2025) in their paper, “Perspective conflict disrupts pragmatic inference in real-time language comprehension.”
Eye Tracking Method to Understand Conversation Conflict
Investigating the nuanced processes of real-time language comprehension, especially when perspectives conflict, requires highly sensitive measurement tools. This is where eye-tracking technology becomes indispensable. Barr et al. (2025) used an EyeLink 1000 to observe how addressees (listeners) direct their gaze while processing spoken language and how they resolve temporary ambiguities when their perspective conflicts with that of the speaker.
Eye tracking offers a unique window into cognitive processes by recording precise fixation patterns as participants view visual stimuli and listen to spoken instructions. In the context of language comprehension, earlier and more frequent fixations on a target object indicate faster and more efficient comprehension. Conversely, delayed fixations or looks to incorrect objects can reveal processing difficulties or ambiguities.
In the Barr et al. (2025) study, a novel “Display Change Task” was introduced to create situations of perspective conflict. In this task, participants (addressees) saw an object change identity on a screen while a confederate speaker, unaware of the change, prepared a description based on the pre-change display. By tracking the addressees’ eye movements, the researchers could precisely measure how effectively they used information about the speaker’s (conflicting) perspective to resolve ambiguities in descriptions like “the small candle.”
Eye Tracking Shows Real Time Processing Disruptions
The results from the eye-tracking data were critical in demonstrating that when perspectives conflicted, addressees exhibited a lower rate of preferential looks to the target and slower response times. This direct observation of gaze behavior provided compelling evidence that perspective conflict disrupted pragmatic inference, reflecting either a suspension of pragmatic inferencing or cognitive limitations in simultaneously representing incompatible perspectives. Without the precise temporal resolution and direct observational capabilities of eye-tracking, it would be significantly more challenging to capture these real-time processing disruptions and gain such fine-grained insights into the complexities of human language comprehension in dynamic social contexts.
