ABSTRACT
The mammalian brain analyzes features of the outer world in separate parts of the brain in parallel. How these features are bound to the percept of a unique object is known as the binding problem. Whereas the neural mechanisms underlying feature binding are heatedly debated less is known about the spatio-temporal characteristics of binding itself. Here, we focus on one of the very basic binding processes, namely, feature fusion. In feature fusion two elements are rapidly presented one after the other at one spatial position. Because of rapid presentation only one element is perceived combining the features of both elements (Efron, 1967). To test feature binding we used a vernier discrimination task.
