Our main interest is in understanding visual perception, more precisely, the analysis of simple visual features and forms in cooperation between different cortial areas to achieve figure-ground segregation and, finally, object recognition. The methods used includes primanly psychological experiments probing visual perception. These are complemented by imaging technigues, such as functional Magnetic Resonance Imaging (fMRI, on both a 1.5 and 3.0 tesla scanner) and multi-channel EEG recording. A strong emphasis lies on the temporal domain of visual perception and on changes over time as a result of perceptual learning (see book "Perceptual Learning").

A second emphasis is on further clarifying the relation between visual function and underlaying central nervous structures (e.g. by fMRI), and by testing patients with circumscribed brain lesions, using a neuropsychological approach (see book "Visual Neuropsychology").
