Eye Movements as a Window into Decision-Making.

Area of Science:

• Cognitive Neuroscience
• Psychology
• Ophthalmology

Background:

• Eye movements have been historically utilized as indicators of human sensory and cognitive functions for over a century.
• Understanding the neural and cognitive underpinnings of decision-making is a key area of research.

Purpose of the Study:

• To review and evaluate the contribution of eye movements to understanding decision-making processes.
• To highlight how eye movement metrics can elucidate various stages and aspects of decision formation.

Main Methods:

• Literature review of studies examining eye movements in relation to decision-making.
• Analysis of how different eye movement metrics correlate with cognitive processes involved in decision tasks.

Main Results:

• Eye movement metrics reflect visual and task contexts during information accumulation and evaluation.
• Gaze patterns indicate efficiency in understanding task instructions, decision timing, reward expectation, and outcome accuracy.
• Eye movements provide insights into confidence and predictive abilities related to decisions.

Conclusions:

• Eye movements serve as valuable, non-invasive, real-time indicators of complex decision-making processes.
• The continuous nature of eye movements allows for detailed probing of cognitive functions during decision formation.
• Further research leveraging eye-tracking can deepen our comprehension of human judgment and choice behavior.
