Can Eye Tracking with gauze behavior, Focus Maps detect Self Perception differentiating True and Fake News?
Eye-tracking technology has become a powerful tool in studying human cognition and behavior, especially when combined with other analytical techniques. It can provide insights into where a person is looking (gaze points), how long they fixate on a particular point, and the path their gaze takes as they scan an image or text.
Using eye-tracking to differentiate between true and fake news based on a person's self-perception (i.e., whether or not they believe the news they're reading) is a novel and intricate challenge. Here are some considerations:
1. Gaze Behavior and Focus Maps:
When people read, they engage in specific gaze behaviors:
Fixations: When the eyes remain relatively stationary, allowing for information processing.
Saccades: Rapid movements between fixations.
If individuals, based on their self-perception, are more critical or skeptical, they may exhibit different gaze patterns, such as longer fixations, on specific information that seems off or inconsistent.
2. Cognitive Load and Pupil Dilation:
Pupil dilation can be an indicator of cognitive load. When processing complex or contradictory information (like that in fake news), there may be an increase in cognitive load, leading to pupil dilation. If a person doubts the veracity of the information, their pupils might dilate more than when they believe the information.
3. Differentiating True from Fake:
The primary challenge is that belief in the veracity of a news item can be influenced by several factors:
Pre-existing biases and beliefs: Someone may believe fake news if it aligns with their pre-existing beliefs or disbelieve true news if it contradicts them.
Presentation: Well-presented fake news may be more believable than poorly presented true news.
Source credibility: Trust in the source can heavily influence news perception.
Self-perception is an individual's self-awareness and understanding of their behaviors, beliefs, and motivations. If individuals are aware that they are more prone to believe or disbelieve specific types of information, this self-awareness might influence their reading behavior, and it could be detected using eye-tracking.
While eye tracking might provide insights into how a person processes information, determining the veracity of news based on gaze behavior is challenging. It would likely require a combination of eye-tracking data, other physiological measures, and post-reading assessments (like quizzes or interviews) to accurately gauge a person's perception of the news they've just read. Even with all these tools, predicting belief in news veracity based on gaze patterns would not be straightforward and would require a sophisticated analytical approach.
