Why visual perception is a decision process

The study shows that humans occasionally perceive prediction errors as illusory percepts. In contrast to
popular predictive coding theories, where the brain 'explains away' prediction errors along a hierarchical processing scheme, our data demonstrate continued access to residual prediction errors.
We propose that such a strategy maintains flexibility at perceptual decision stages when coping with highly dynamic and ambiguous sensory input.
This research was done in collaboration with colleagues from the Freiburg University, and primarily funded by the SFB 874.

The Institut für Neuroinformatik (INI) is a research unit of the Faculty of Computer Science at the Ruhr-Universität Bochum. Its scientific goal is to understand the fundamental principles through which organisms generate behavior and cognition while linked to their environments through sensory and effector systems. Inspired by our insights into such natural cognitive systems, we seek new solutions to problems of information processing in artificial cognitive systems. We draw from a variety of disciplines that include experimental psychology and neurophysiology as well as machine learning, neural artificial intelligence, computer vision, and robotics.
