Eye Movement as an Indication of Proactive and Reactive Control in Switch/Repeat Tasks
Abstract
Two main components for effective cognitive control are top-down and bottom-up processing. Top-down processing is described as the ability to use previously known information to create, seek out and achieve a goal. Bottom-up processing is described as making a reactive decision, based off the immediate sensory information available. Top-down predictions and bottom-up sensory processing must work simultaneously to interpret one’s current surroundings for the purpose of decision making. We believe that top-down and bottom-up processes are also correlated with a person’s innate level of impulsivity. This project aims at using eye-tracking data to determine if there is a correlation between where and how quickly a participant will look at a given stimuli before making a decision. Then, we aim at determining if a participant will proactively set their gaze in a certain location before a stimulus is given, indicating top-down control when making their decision. This study will provide more insight on the question of how we, as humans, make daily decisions.
