Prediction, prediction error and learning in peripheral vision

Prediction mechanisms are fundamental to peripheral vision. Predictions, either acquired through learning or constructed based on the interpretation of the visual scene, inform the appearance of peripheral vision beyond the limits of sensory processing. At the same time one of the most fundamental functions of peripheral vision is predicting where the most useful information can be gathered through foveal vision, and thus to guide eye movements. In this project we will investigate how predictions shape peripheral appearance and how peripheral vision is used for gaze orienting.
