Control of eye movements by informational value

Planned research

We actively sample visual information from our environment by moving our eyes to different locations. In any moment in time, the most valuable location has to be selected as eye movement target. In this project we want to study whether target selection of saccadic and smooth pursuit eye movements is determined by the expected informational value for a given perceptual task. We define expected informational value as the task-relevant information that can be gained by executing an eye movement. We will compare target selection to predictions of ideal observer models under different perceptual tasks.

Current research

In any moment in time, there are several possible eye movement targets. In order to decide whether and to which target an eye movement should be executed, these different possibilities have to be evaluated. In this project we want to study whether saccadic and smooth pursuit eye movements are modulated by their expected informational value for a perceptual task. We define informational value as the information that can be gained by an eye movement. We will manipulate informational value explicitly by setting different perceptual tasks with different requirements with respect to spatial acuity and retinal stabilization.
